I own both of these cars, a 2017 Bolt and a 2018 Tesla M3. My wife drives the Bolt, I drive the M3. We both had EVs previously, a Leaf and a Spark. What changed principally from day to day is that we don't both rush for the charger every night. My wife likes the hatchback, the fact that the Bolt is slightly smaller, and she appreciates the fact she does not have to worry about range to get anywhere around the city. She rarely if ever charges away from home.
I have a long commute, 44 miles round trip, charge about every 3 days, and use chargers away from home only when we take long trips.
The biggest difference between the cars is charging away from home. We went from San Fransisco to Los Angeles in both cars. In the Bolt, we were restricted to highway 101, a longer route, because the shortest and most heavily traveled route has no CCS chargers. At all. According to plugshare, it still does not. Trying to charge down the 101 is somewhat hit or miss. There "appear" to be a lot of high power chargers for CCS, but most of them are actually 1/2 power chargepoint 25kW stations that take way longer to charge. On the way down we made it with one charge, but we left fully charged, stopped for 2 hours (!) at a 50kW charger, and barely had any charge when we made it to San Fernando Valley. On the way back we hit three chargers, made worse because the hotel we stayed at had no charger, so we had to hit one on the way out. Note: if you can find a hotel with a charge spot, even only an L2, this is a huge help, since you leave the hotel fully charged.
With Tesla we left fully charged, hit the Harris ranch charger even though we could have gone farther, and charged twice in LA before returning on the I5. Another charge at Harris ranch got us home.
There really is no comparison between cars when it comes to on the road charging. With CCS charging you are luck if there are two 50kW charging spots, and the chances are good one of them is out of order. When you get there you fiddle with a card, and even having a card does not always help. My EVgo card works only %50 or less of the time, and they have sent me several replacement cards. Thus I waste 10 minutes at each charge calling them and setting up a charge on the account.
With Tesla, we go to chargers and there are 10 spots, with some up to 20 (!) spots. You plug the car in and go. The billing is completely automatic, and the prices are reasonable. There is an odd thing going on with the A/B system, if you plug in to A, and another car is on B, or vice versa, you both get slowed down, so you pick an A-B pair that is unoccupied. Coming into a charge station at about 50 miles left (my personal minimum), you get to see the car charge at over 100kW/h for about 2 minutes to reach over 200 miles left, then less after that. Its truly a breathtaking sight to see a car charge that fast, and apparently this is unique to the model 3, which has improvements in charging speed even over the Model S.
In short, we are happy with both cars, but the Bolt is clearly a local, city car, and the M3 is for long trips.

The more i look at it the more i like it.
"Not for everyone" is an understatement, but the price, performance, utility and features are a compelling package for site workers in all construction fields.
I suspect it will develope a hard core of fans in that market who, like early Tesla car adopters, will sell their friends on the product. The styling and features will become the new normal, and on the road, as you said, it will turn heads like nothing else, and that is what some people want.
Round some edges a bit maybe and influencers will do their thing. I have a construction background and many younger tradespeople i know would love to roll up to the job in one of those, just to mess with the boss and show off the features to their peers.
This is like the original Roadster, a technology demonstrator and market awareness ploy. I suspect future iterations will reflect consumer input to some extent, but that the market will come to accept and embrace this new design language. Millions of future buyers are in their teens today, and old dudes like me are literally a dying segment of consumers. Society, ultimately, changes one funeral at a time, but tastes can change on a dime. We shall see.

Ricky, sorry for a long write-up but as you will read on it will make sense. I moved to Barcelona from NC back in 1989 for a 3-5 yr job which ended in my finally retiring here after falling in love with Spain, Barcelona and lifestyle. As usual, I went to Sagrada Familia in back then for the first time and was thoroughly impressed but it was still just a shadow of what it is today. Back then, and looking at how little it had advanced throughout the years, I thought it would take at least another 50 years. I remember my wife and kids going up the towers by the circular staircase, I refused, and they told me about the broken glass that is cemented in the top of the towers to reflect different colors - talk about designing detail few would ever see.
Every to time friends from visit it is an imperative to visit Sagrada Familia and I see the progress which has been impressive. The construction has been advancing and I do believe that they will meet the timetable of for Gaudí's 100 yr death anniversary.
When you talk about the inverted structural sand analysis it reminds me of my first thoughts upon seeing it. As a civil engineer, although never actually worked as as one, it reminded me of the structural classes with vectors which are a very graphic way of designing relatively simple structures but in this case taken to an unbelievable level.
As a final note on Gaudi may I say that Gaudi was a genius and the only architect I know that when you see a building he designed you can immediately say THIS IS A GAUDI. There are 2 in Paseo de Gracia Avenue in Barcelona, Casa Batlló and La Pedrera, as well as Parque Guell which are worth a visit. I never forget a company Christmas dinner we had in Casa Batlló where you could see the detail even in the individual doors/frames to the apartments which are just unbelievable. I also remember seeing on visiting Leon where immediately remarked this is a Gaudi. Lots of respect to the man's genius.

Last week the clean air as a result of this global lockdown, has been the talk of the day all around the world, with wonderful pictures of cities finally smog free... I am sure thousands upon thousands of people who were already weighing their options between an electric car or one more time an ICE car, now have definitely flipped to electric, as we now all can experience ourselves first hand what it does to our environment. Other people might not wait any longer and buy an electric car as soon as they can, I am in this catagory, thinking about doing away my gasoline car early and buy a Tesla... I hope the Model Y comes out in Europe soon.. WITH a tow hitch! I have a reservation for a Cybertruck, but that takes I think at least 3 years, and is way too big for me and our narrow roads and parking garages.
So yes, that stupid Trump move is just a temporary band aid, and will need a replacement sooner than he might think. GM and Ford are doomed, speed of innovation at Tesla and startups like Rivian, NIO, Byton, Fisker, Lucid... Just to name a few, will together oblitarate the Old Legacy Automakers sooner then we might think, Like Tony Seba said, they will face "Market Trauma" just like Kodak, Nokia and GE in the past within this decade, Tonay Seba has brought his prediction forward that sales of new Ice cars will drop to zero by 2025, he used to say that would happen 2030.
I like the video's you made lately quite a lot, therefore Liked and subbed.

Good production, but I have a few little quibbles. You mentioned batteries losing energy while they sit idle, but lithium-ion cells don't really self-discharge the way other rechargeable chemistries do. At the same time, hydrogen is notorious for gradually leaking out of any storage container. Furthermore, all electric cars, whether BEV or HFCV, will have some small amount of "vampire energy drain" through their electronics when sitting idle, just like a computer in sleep mode.
When you talk about the huge energy density of hydrogen, it's very misleading, because the physical density is so low, volume rather than weight becomes a limiting factor. Compressing the hydrogen to high pressure helps with the volume problem, but then you need a much stronger, and heavier, tank to store it. Then the energy density of your complete storage system plummets. Rather than individual li-ion cells versus hydrogen gas, you need to compare the filled hydrogen tank against the complete battery pack. And then it seems fair to acknowledge that those bulky hydrogen tanks present a real packaging problem for car designers, too. By comparison, BEV designers are almost all going to a "skateboard" design with batteries in the floor, which seems to be pretty versatile and efficient.

Good analysis, but while I agree with the basic premise...that Porsche is just way behind Tesla, I think that some of the reasoning was incorrect.
First, it is simply not true that Tesla doesn't sequester battery capacity. Various folks have analyzed this (like Bjorn) and it appears that for a Model 3 long range/performance the actual battery capacity is about 80 kw, of which you can access about 74. So, when you think you are charging to 100%, you really aren't. While it's possible that Porsche sequesters a larger percent of the capacity, it's not clear that they do. Bottom line is that they both limit how much of the battery you can access, both at the top and the bottom.
Second, you are mixing up efficiency and range. Range will be a function of capacity and efficiency, but efficiency is what this is really all about. It wouldn't matter what size battery the Porsche had (or what percent was sequestered), the efficiency is just lousy.
Third, the idea that part of the Porsche's problem is due to their tying regeneration to braking may not be entirely true. According to Porsche, the vast majority of their braking is coming from regeneration, not friction. In fact, they brag about how they can regenerate more than anyone else due to their "800 volt architecture". The fact is, when you need to slow down you can either take your foot off the throttle (as is the case with Tesla) or you can use the brake pedal. But assuming the same level of motor regeneration is available, it doesn't matter (from a physics perspective) which method you used. It's all about feel, not regeneration. Again, if we believe Porsche, if anything their system should result in MORE regeneration rather than LESS regeneration.
So, if these aren't the reasons for the low efficiency, what is?
1. The car is too heavy. For a car with less interior and storage capacity than a model 3, it weighs over 1,000 lbs more. All that weight requires energy to move it.
2. The car probably uses higher rolling resistance tires. This is definitely a choice Porsche is making to optimize handling over efficiency.
3. The 2 speed transmission is a problem. I'll talk about why they did this a little later, but suffice to say that this adds weight and frictional losses.
4. The car uses 2 PM motors rather than one PM and one inductive motor. This may not seem like a big deal, but it is. PM motors are more efficient than inductive motors, so it makes sense to use them as the primary motor in a 2 motor vehicle. Inductive motors are less efficient than MP motors but they have the advantage of having less drag when idling...as they are most of the time in a properly designed 2 motor vehicle. So, unlike Porsche, what Tesla has done on dual motor cars is to get the best of both worlds by using a PM motor at the rear and an inductive motor at the front. Clear evidence of the benefits of this can be seen with the Raven architecture on the S, where they added significant range/efficiency as a result of invoking this architecture that was pioneered with the Model 3.
5. Going back your original point about Porsche just being behind, here are some specifics:
a. It's clear from the Model 3 dissection done by Munroe that there is some advanced technology in Tesla's control systems and motors. They believe that the magnets used in the motors are extremely complex and not easy to copy. I suspect that Porsche's motors simply aren't as sophisticated.
b. I suspect the energy density of the Tesla batteries is higher than the Porsche batteries. This is because unlike Tesla, who seems to be at the state of the art of battery technology....and controls the manufacturing of their cells, Porsche is buying off the shelf batteries from LG. The result is lower discharge rates for the same capacity and lower power density, resulting in a heavier and lower performing pack.
It seems that for EVs, lots of little things add up. This bring me back to where you started. Porsche is simply a number of years behind Tesla, and while they were (barely) able to equal Tesla's performance, they could only do it by having really bad efficiency. I sort of feel sorry for the folks buying a $250k Taycan only to find out that it's going to be hopelessly obsolete within just a few years.
Keep up the good work!

Good video, nicely encapsulated. Domestic roofs and walls are, more often than not, doing nothing other than offering shelter and waterproofing to people. So they are free space largely going to waste in terms of power generation. Would seem to be a natural space to put solar photovoltaic panels and batteries to me. And instead of putting flammable coatings on high rise apartments, cover them in solar panels. You get 30-40 years of power generation, and the panels do a half decent job of keeping the weather out too. Put batteries on the roofs and put solar panels on top of them. Seems obvious to me. Do enough of them and they produce as much power as a conventional power station, and for cheaper. Do several cities of them and you produce as much power as a nuclear station for a fraction of the cost. Of course, the drawback is, who pays? Well who pays for another nuclear power station that nobody wants and is too costly to build anyway, and will never be turned on because the electricity coming out of it, if it ever gets built, will be too expensive?

The days of "Big OIL" are numbered but not for oil as a whole. Way too many modern conveniences are made from oil byproducts. Cars are a big consumer of oil products and sustain the industry at high level of efficiency, diversification, and redundancies.. Shipping {diesel trucks and trains; cargo ships}, home heating {natural gas and/or propane - HVAC, water heaters, clothes dryers, bbq grils, etc; fuel oil HVAC, etc), food (agricultural tractors, combines, etc.)… the "non-car" list is quite long and extensive! Great video! Thanks for sharing❗❗❗ 🙂🙂🙂 👍👍👍

The concept of a range extended EV isn't new. I have a BWM i3 REx, which is one of the only production vehicles I know of that uses this architecture. It's essentially a "series plug-in hybrid", but what makes it a range-extended EV is that your primary "fuel" is electricity from the battery, which ultimately comes from the grid or home rooftop solar, and gasoline is supposed to be your secondary fuel, or support to bridge the gaps between charging stations on a road trip.
It works really well. The only problem with the series hybrid design is that it's less efficient than letting the engine directly drive the wheels. Toyota's hybrid architecture is "series-parallel" such that the engine can, in certain conditions, directly provide mechanical output to the drive shaft/transaxle. This is especially desirable if your battery is depleted and you're cruising at highway speeds, and even though it results in a more complex "transmission" (e.g. with a planetary gearset, or a clutch pack like the Honda Clarity PHEV), it is ultimately more efficient when running on gas than a series hybrid.
The inefficiency of the series hybrid is awfully clear when you consider how it runs when the battery is nearly depleted. It generates mechanical work, then a generator converts that to electricity, then that electricity goes into the battery, then the battery gets discharged to drive the electric motors, which convert the electricity back to mechanical work. Every time the energy is converted, you lose some efficiency. Even if each step is very efficient, when you combine them together, you lose a lot of energy. Regenerative braking helps a lot in heavy traffic, but if you're going at highway speeds over long distances, running on the REx is gets pretty poor MPG. It's in the high 20s last I tested, like 28 MPG. Icky.
If I had my way, we would adopt one of these small-and-light "generator" designs -- this one or some other -- as the range extender in a so-called "series-parallel plugin hybrid" with an architecture similar to the Toyota Prius Prime or Rav4 Prime, but with a much larger battery pack. Let's say we can shrink the weight and size of the engine by 50% and triple the size of the battery pack. This would give us an EV range around 150 miles, which is enough for all but road trips. Then we'd have an 8-10 gallon gas tank which can easily bridge the gap between charging stations, even if you pull into an Electrify America station and all the chargers are broken. Oh well, just drive on gasoline for another 20 miles until you find the next one.
A car of this design would work perfectly fine even in a charging "desert" (where all the chargers are broken, or they don't exist), and at a decent fuel efficiency, too (probably 40 mpg or higher in a mid-size sedan configuration). But it would also have 150 miles of EV range, so if you charge it up at home, nearly all trips, even "regional" trips (say, trips from the Baltimore area to the Washington DC area) could be taken completely on electricity. But if you needed to drive out to the midwest, and you couldn't find good chargers or didn't have time to stop, you could just keep driving on gasoline, and fill up every 200-250 miles at a gas station.
That would be the "dream car" for me, and I would probably buy cars that operate on that architecture for the rest of my life. 95% of my driving would be fueled by the grid (so, its "cleanliness" would depend on the energy mix of the power grid) and partially offset by my rooftop solar. The remaining 5%, those long distance trips, would not require me to rent a car -- I would just use gas to the extent necessary.

My wife and I bought a Bolt as soon as they were available in our state. We are really happy about the purchase and have owned the car for nearly two years now. I haven't had a chance to drive the Model3 yet for comparison, but the Bolt has plenty of torque and is certainly fun to drive. We primarily chose to buy it over the Tesla because it was cheaper, available immediately, was a hatchback, and Tesla's spartan interior design is not for me (I'm a button and knobs kind of guy).We haven't even charged at a public charge station yet and are only using the 120v outlet in our garage. Though I should add that we also kept my '02 manual Celica for long distance trips, but it sees very little use these days. Really there have only been a couple of times that we felt restricted by the charge limitations of the Bolt, the 200+ mi range has been more than enough for our driving habits. We don't even charge it to 100% every night and in the summers we see closer to 300 mi range.So far the car has been a very reliable. I love letting friends drive it around a bit and everyone likes the tech and how fun it is and most are surprised to learn that you can literally charge from any 120v outlet anywhere and how low maintenance/reliable electrics are (including the battery packs).My wife and I are glad we chose the Bolt over the Tesla but we would highly recommend both to anyone considering a new car, let alone an electric. For those who are concerned about range, please do your self a favor and just buy Chevy's Volt. I personally think the Volt better represents the future of transportation with it's zero emission, reliable and efficient 100% electric drivetrain, but the added benefit of a small onboard combustion engine to generate electricity for the electric motors when you need to drive further than the 50+ mi range of its small battery pack.

Hi Brian and Ricky, I met both of you at Fully Charged Vancouver last September. What do you think about how Elon seems to be attacking the Tesla base? Tesla has increased the Model 3 by $9000 in Canada starting February 1st. Oddly, on the same day, Trump threatened to saddle Canada with 25% Tariffs. I was a huge fan of Tesla, but now that Elon is throwing salutes from "his heart," not so much. Great company, very poor international optics. Love my Tesla Y, but will soon trade-in for a Ford Lightning to try and wash some of the bad vibes Elon is sharing. Unfortunately, in the long term, if Elon doesn't move on, I don't really see a future for Tesla.

Just discovered your channel. I work for a major Class 1 railroad and this accident is “The Big One” we’ve all been talking about since the carriers have adopted PSR. The reduction in staff, mainly in the maintenance departments, is astonishing. As an example, on my territory, everyday at least 3 trains are stopped because of mechanical issues. And as far as our pay raise is concerned, I was very vocal about this. Keep your money and let me call off when I need to. The average person works 5 days a week so, they have 8 days off per month plus 11ish holidays so, the average person has about 100-110 days off per year. With my seniority, I have now reached the point where I get 30 days off. Oh, and they have to be scheduled…anyway, when it comes down to it, this accident is because of PSR. And I’m afraid it’s going to happen again….thanks for posting about this.

I’m an electrical engineer who spent nearly 20 years designing and operating many parts of the Western Interconnect (the U.S. lower 48 has three main grids: Eastern Interconnect, Western Interconnect, and the Texas ERCOT. And while the “grid” is very complex, there are many automatic relays that help maintain stability (frequency and voltage). Bulk power operators bring generation on, off, or raise/lower power output to maintain stability, yet there are millions of devices that can shed load when frequency and/or voltage get out of spec. I also spent 15 years working at the national laboratory (DOE EERE NREL) and supported the development of standards and codes that are critical for integrating distributed energy resources (DER) to the various grids. It’s definitely an extremely complex system, the Grid, and it’s highly unlikely that batteries and EVs can stabilize a stressed out electrical grid of any size or location. Some in the Green New Deal community are actively pushing for the elimination of anything that burns, which is, in my humble opinion and many others, dangerous as we cannot rapidly raise the use of electricity as would be required if you were to eliminate gas furnaces, stoves, gas peaked power plants, and all things petroleum. People need to listen to those who build and operate electrical systems as they do know a thing or two about these topics. Well shoot, I have too many things to do rather than writing responses here. Cheers.

Great discussion of the voltage and amperage issues. You didn't mention the difference between operating voltage and open-circuit voltage, so lets be sure that people understand that.
Open-circuit voltage is the voltage the panel(s) generate when there is no current being drawn. The total open circuit voltage in series must be lower than the maximum voltage accepted by the inverter. So if you have three panels in series, you take Voc * 3 and make sure that number is less than the maximum voltage the ecoflow can handle. Also note that even in shade, a solar panel will generally be producing its open circuit voltage when open circuited (no current).
Operating voltage is the voltage the panel(s) generate when operating at their maximum power point. It also tends to be roughly the voltage the panels operate at when partially shaded (just with less current). You want the total operating voltage in series to be within the MPPT range of the EcoFlow. And its actually a bit more complicated because you also want the inverter to be able to handle a partially shaded string, so really you also want the total operating voltage in series, minus one panel, to also be within the MPPT voltage range of the inverter.
Also keep in mind when calculating the total possible production, that the production is occurring at the operating voltage, not at the open circuit voltage. So you want the total operating voltage of the string to be as high as possible to make as much production as possible given the current limit of the inverter.
--
Now there is a huge problem with partial shading in a parallel x series configuration. In your case, 3s3p. The problem is that if a panel in one of the series is shaded, the optimal operating voltage for that string is far lower than the optimal operating voltage of the other strings connected in parallel. Since the voltage is forced to be the same for things connected in parallel, this will cause the partially shaded string to contribute almost no current (essentially losing the entire string instead of just the shaded panel) due to the other strings forcing the voltage higher.
This is why you generally do not want to parallel strings, not in modern day. You want each series string going into its own dedicated MPPT. That way partial shading on one string only drops out the partially shaded-panels in that string and allows the rest of the panels in that string to fully contribute to your production.
--
And there is also a problem when you parallel more than two strings. Nearly all solar panels are specified to only be able to parallel two strings without fusing.
The only safe way to parallel more than two strings (and I would argue even when paralleling just two strings...) is to run them through a solar combiner box that includes a series fuse for each string. If you don't do that and one of your strings shorts out (due to damage or whatever), the other strings in the array will feed their entire combined current into that one shorted string. If you have more than two strings in parallel, that can cause a fire. That's why a proper solar combiner box is necessary when paralleling panels or paralleling strings.
(But as I said above, in modern times you want to avoid paralleling strings if at all possible and have each string going into its own dedicated MPPT, to ensure that a partially shaded string can still contribute to production).
--
And there is ALSO (yet again) a problem when paralleling a lot of strings... now the highest possible current might exceed what DIYers actually use for their wiring. And that can cause a fire too. As long as there is a series fuse for each string, then the wiring for each string only has to nominally handle that string's current contribution. The trunk (after the paralleling) wiring on the other-hand must be able to handle to the total combined current. Getting 30A-capable "solar" wiring and MC4 connectors for this is easy. Once you head north of 20A, though, a lot of the cheap stuff people buy starts to have problems. Cheap MC4 connectors, cheap wires, bad crimps, etc... things can get dangerous in a hurry. Yet another reason not to parallel more than two strings.
Hand-touching the MC4 junctions and all the wiring during full production is a good idea to make sure there are no hot spots.

Love the specs and pricing, and although I really appreciate the courage Tesla showed with the design, overall nope, just don't think it's for me--looks like I will stick with my first choice, a Model Y. Too bad, as I wanted to love this truck (really liked a couple of the pre-reveal renderings I saw online) , and per Elon's comments pre-reveal, I knew it would be different looking--warmed up a bit to the front end design, but the back half of the truck (not a fan of sail pillars), just a no go for me. That being said, I am glad the pre-order numbers are strong, as I love the company and want it to do well, but I won't be buying the truck--AWD Model Y for me in 12-18 months if I can swing it!

A fair overall assessment. Unfortunately I’m not surprised as to why we are not seeing more reporting on this incident based on where the money is coming from. A few thoughts. Maintenance, not just in the train business but throughout US industry, is lacking. For example bridges, water treatment, electricity grids, and the list goes on. The US infrastructure and manufacturing base has woefully declined which will probably lead to more of these types of disasters. The US could benefit from a focus on training many more people in the trades. As far as the train employees benefits it would be helpful to know their full compensation package for perspective in order to judge their time off, sick days, and other comp. Would also be good to know the breakdown of the rail companies expenditures for R&D, employees, regulatory mandates, etc.

Thank you for you videos!
I live in Phoenix, AZ, and I just bought solar and storage, based on knowledge I've gained from your channel.
I did go with Tesla, after quoting other companies.
16 kWh pv and 3 power walls.
Cost wise, worst case with interest on a loan, I break even in 20 years. Not planning on moving, ever. Paying off the loan sooner, we then save $2-3k a year in electricity, or offsetting the Time of Use plans.
For emergency preparedness, the #1 reason I got the system, is excellent. My house is 100% electric. We use near 45k kWhs a year. 2 A/C units, 2 electric cars, a large pool, my spouse bakes often, and my kids keep every electrical device on. This system should keep us from being dependant on the grid during the day, use our powerwalls in the evening, and we can run our pool pump, and charge our EVs on the super-off-peak hours of 11 pm - 5 am, at 5-6 cents a kWh.
Hoping to do our part, to help the environment, with an exchange of financial costs.
I do hope they enable off-peak charging for the powerwalls in the future!
Thanks again!

You misspoke when you said the Cybertruck has ground clearance of up to 16 feet. It's inches. I doubt anyone would be misled, though.
The Hummer will have 35" wheels. Don't know yet if that's an option or standard. It'll be much more expensive than the top-tier Cybertruck, but man, if you have to go off-road, the Hummer will have insane ground clearance. Exactly what that will be, we don't yet know.
Several of those brands you discussed might not make it to production.
Bollinger's cost versus capability looks like a bad deal for consumers, though the design is interesting. They're looking weak.
Nikola strikes me as a pure scam, rip off investors then fold the company, though I hope it isn't so.
Atlis makes compelling CGI pictures. That's about it.
Rivian has already signed a deal to sell 100,000 vans to Amazon, and they'll supply skateboards to Ford; they're looking like they might succeed, though the unit cost seems high.
The best deal is undoubtedly the Cybertruck. For $50K you get a truck that competes well against any of its rivals for far less money. For $70K you get 500 miles of range and the best performance of any of them. And with the cold-rolled 3 mil steel body, you get durability we've never seen in a consumer automobile of any sort. You want tough? This is where to find it.
It's sort of shocking just how many contenders will be entering the e-pickup space in the near future, even if a few of them fail. Things are moving fast - if they can all secure the battery cells they'll need. Tesla has secured its own supply chain for battery cells; everyone else will be scrambling in an open market where supply lags far behind demand. We'll probably see some schedule slippages and slow production ramps from most of these rivals.

They said heavier than air flight was impossible, so much so, when the wright brothers first flew at kitty hawk, no news paper even sent anyone , no photographer, they said it wouldn't happen, 60 years later there is an air force, fighter jets, thousands of airports, tons of aircraft, ppl flying all over the world everyday!! But everyone was convinced it was impossible, but the wright brothers were wright, as in correct!!

As usual, a very well balanced evaluation. You even managed to explain the political shenanigans without getting political. One item you did not cover was reliability. As a retired Director of Engineering {EE}, I love most things electric/electronic however, living in Western NY, for over 70 years I can say I've NEVER lost Natural Gas while lost of electricity is normally a 4-5 times a year event. I had contemplated an Induction cook top but did not do the math like you did and the $$$ increase for electric was quite eye opening. Cost and lack of reliability are two obstacles to converting from Natural Gas for cooking. In the last 3 years, I've had to use our wood stove for heating a total of 4 weeks to assure we don't freeze when the electricity goes out. I may look at a biochar reactor to generate gas to run a generator if NY keeps playing with our energy sources. We have enough wood to do this but not everyone does.
NY has imposed their ban on Natural Gas appliances with a goal of banning replacements [I'm sure when the public gets used to government restrictions on fuel choice]. NY State just announced a major KW/hr price increase to strengthen the grid which now fails mainly from wind storms and the occasional capacity failure in hot weather. Our grid is at the limit and EVs will push it over the edge. Even though a Tesla Model S is my dream car, I dislike my government telling others what type of car they MUST drive.
I'd love to see a TRUE and centuries old solution, biochar, used for both energy production AND sending 25% to 35% of carbon back into the soil where it will improve water retention, reduce runoff, minimize fertilizer requirements {encapsulated in the biochar} AND where it will sequester this excess carbon for thousands of years. Couple this with regenerative agriculture and the world would be on the road to true reduction of CO2 and other "greenhouse" gases.

Yeah, a good, rational appraisal. FSD is an incredible achievement already, and if your money’s on anyone reaching autonomy, it’s Tesla. But amongst all the furore, we seem to be loosing grip on what Tesla are fundamentally...transport, tech and energy company, that are quietly expanding into energy provision, and ‘accelerating the world in adopting sustainable energy and transport’.
They’re shaking everything up. Tesla’s worth is in this, and to me, FSD is the icing on the cake. We didn’t buy FSD with the car, precisely because we have a finite amount of spare cash (we’d have grabbed it otherwise), and therein lies the conundrum...how many people can afford it? FSD itself is priceless, but the irony is that it has to be cheap for universal adoption, or it won’t solve the road safety goal.
Elon’s excitement and optimism is fully understandable, but unfortunately, there’s a pragmatic realism at work. I believe that a subscription cost would bizarrely, have to be around £9.99 per month. Tesla cars (all their products) are ridiculously good, but for mass adoption into the future, they have to be ‘cheap’. I know a heck of a lot of people who want them, but can’t afford them...yet their products are actually worth more than we pay for them now. Paradox.

Thanks for covering this Ricky. As micro-turbine gas-electric generators already are capable of about 70% efficiency, are very compact and simple, why not use them instead combustion photovoltaics?
In regards to your concept of photovoltaic ICE exhaust power recovery, I'm thinking that if you were able to recover 50% of the waste energy from an ICE exhaust using photovoltaic generator, you would be recovering about 15% of the total engine thermal losses. Having worked with large Exhaust heat exchangers (stack robbers) to capture waste exhaust heat, but due exhaust restriction and back-pressure reducing engine power, we typically only recovered about 30% of exhaust heat. If similar was the case with photovoltaic recovery, you would only be recovering about 15% of the waste energy in the exhaust stream, and something like a exhaust power recovery microturbine, adapted from a turbo-charger to drive an electric generator might be as efficient and less expensive.
BTW: Back in the 80's when I was working for in the Oil and Gas Industry and dealing with HPS and Mulit-Vapor lighting systems, the thought of using high temperature combustion gas to produce combustion based lighting using a multi-vapor tubes for remote off-grid locations occurred to me. I mentioned it to some engineering colleagues, and we estimated the efficiency could be considerably higher than electrically excited tubes but the maintenance, cost and complexities of producing such a system would likely be practical and affordable, plus having combustion sources in flammable environments is not suitable.

Really well researched video. I am also an engineer, and retired about 10 years ago after 43 years in aviation design. My retirement gave me time to do much more detailed research into the quality of the more recent aviation NTSB investigations. As a result, I must disagree with one point you made in the video. The NTSB of today is not the NTSB of 10 years ago, at least the aviation side of the organization. Their investigations have been quite shoddy in the last 10 years or so, with more consideration to political concerns than safety concerns. If these railroad NTSB investigators are anything like today's aviation investigators, I have little hope that anything good will come out of this. I do, however, agree with your idea of separating hazardous cars into separate trains that have special handling rules including things like reduced speed limits, length of train limits, closer spacing between defect detectors, etc. Thank you for the great video.

Thank you. I'm an environmental scientist. I support nuclear power. However, due to the diving costs of wind, PV and storage- most new nuclear facilities don't make sense (besides maybe in places where land is scarce). SMRs might be 20% cheaper than conventional nuclear plants, but they're still more expensive than wind/PV +storage.
The sad truth is that the environmental movement in the 1970s-1980s was hysterical regarding nuclear power (mixing nuclear weapons anxiety with nuclear power), and it led to the halting of nuclear energy development. The result? Climate change now, instead of in 2050 or maybe even never. Not to mention that per KWh produced, fossil fuels kill 10,000s of times more people, and their externalities (health, economic and environmental damages) cost 1,000s of times more- compared to nuclear power (without even taking into account climate change externalities).

We have come to the ID4 RWD from a Bolt EV (battery debacle) and you’re review is spot on, the charging curve for this vehicle is great, 30mins and you’re at 80% and ready to move on, plus 3 years of free charging on EA! I agree the tech is not Tesla level, but you can have wireless CarPlay! The size and storage is great, plus you get towing capability! Acceleration is more than adequate, but not Tesla performance, but you are paying much less and you could go for the AWD.The only stumbling block to make this vehicle is a real winner is getting the OTA updates coming out regularly as VW has promised, that is lacking at the moment. But, definitely if you coming from an ICE CUV check this out, a much better built Model Y with VW/Audi build quality. Plus, all doors have mechanical releases, so you can get out in an accident, no fear of being trapped in the back seats and having to crawl out the front drivers’s door, that has always bugged me about Teslas and having kids in the back seats.

Great video.
Here’re a few useful work around/fixes I’ve picked up from various Tesla forums;
1. When the reverse screen goes blank, perform a reset, by holding down both scroll wheels for around 10 seconds. The Tesla ‘T’ will appear, and the screen should reappear.
2. If the entire screen is black, do the same thing, and it should be back on again. The car is still fully functional with a blank screen........even autopilot.
If reseting/rebooting doesn’t work, try removing anything you have plugged into the usb sockets, such as dashcam, and a music usb stick, etc, and then hold down the scroll wheels to reboot. This also works if an ‘update’ download hangs.

Back in 2008, I designed and built a 3/4 Hp, 6 speed electric road bike.
It worked as design, able to go up steep hills or cruise at the designed 16 mph.
I rode it 11 miles each way to work and back all that season.
I discovered that riding my bike uphill next to traffic, without any pedaling, REALLY ticked off some car drivers. I was hit by passing, open doors and shoved off the road several times. Unfortunately, a pickup truck driver pushed me off the road into a construction area. The result was a 180 flip and a head-first smash into the road at 16 mph. I put my hand up in front of my face in a fist to protect myself, thereby punching myself in the left eye hard enough to crack my skull above my eyebrow, get one hell of a concussion, cracked numerous teeth and blow out the bottom of my left eye socket.
Mind you, I used ALL the relevant safety gear: A helmet, polycarbonate wrap-around safety glasses, a sweatshirt with multiple, bold, reflective stripes, etc, so I know the people who pushed me off the road did it on purpose.
The moral here, and the purpose of my post, is to emphasize all aspects of safety and not just go all gaga about electric bikes. E-Bikes are not dangerous - car drivers can be, and it only takes one 'hole who thinks it's cool to slam yo with a door or put you in a hospital while the doctors wait to see if your brain will swell, dangerously.
The host and creator of this video said NOTHING about safety.

Thanks for calling the model Y a "crossover".... I CRINGE when people constantly keep calling it an "SUV", it is NOT an SUV people! And Ricky, "traditional" SUV's are body-on-frame (Tahoe, Sequoia, Ford Expedition, Lexus LX), but modern-day full size SUV's (Honda Pilot, Acura MDX, Chevy Traverse) are unibody but still large enough to be in the SUV category. I know you are a Honda guy (so am I!). I'm 6'6" and my daily driver is a Honda Prelude. All of the men in my family are between 6'4-6'10". So, size is important for me. We have 4 kids under the age of 7 (who won't always be so small). I currently own 2 Honda Odysseys, not because they are cool, but each holds my entire family including luggage/Costco trips, and with ease. And I know you had a Honda Pilot, because you liked the room (otherwise you would have bought something smaller, like a CR-v, or Fit). Now, I LOVE Tesla and Elon musk, SpaceX, he is a genius and great for humanity. I'm a recycling Nazi and pro-Earth guy, who dreams of owning a solar roof and 100% electric cars. HOWEVER... Tesla doesn't offer a vehicle for me. The X is what I would call a larger crossover (NOT an SUV), but who can afford his/her model X's? The 1%ers. The Y is a smaller crossover and when it offers that 3rd row, it will be a joke. I can put a 3rd and 4th row into a Prius, that doesn't make it a 7 or 10 passenger car. Maybe for tiny kids if you wanted to trade in the car again once your kids outgrew the kiddie 3rd row. I think manufacturers throw a 3rd row into a car "just" to check a box, not for comfort or practicality. Anyway, for practicality with large families/Costco-runs, Odyssey's are the most practical. For cool factor, you might downsize a bit into a Honda Pilot (still 8-passenger!) or even into the smaller Acura MDX (7 passenger). Or for smaller family's, can do the compact-"SUV" CR-V. But even the model Y is SMALLER than the medium-sized Honda CR-V. So, I'm dying here... WHEN is Tesla going to make an ACTUAL SUV.... Where is Tesla's version of an 8-passenger SUV (Tahoe, Escalade, Pilot) or even "gasp" a Tesla mini-van... ok, I won't hold my breath on that last one. Plus, all of the Tesla vehicles are naturally smaller inside because they all have the same sloped rear roof (like a Honda Crosstour or BMW X4). They do it for the sake of range, but rear passenger head room and Cargo room suffer! Again, I don't care for range... give me 8-passenger electric "SUV" with a squared off back (i.e., Honda Pilot, Chevy Tahoe, Odyssey) and I'd totally be fine if it had less range (200 miles should be easy). Heck, I've NEVER EVER EVER wanted a pickup... I hate them... that is, until I saw the CyberTruck... I was smitten...it was LOVE at first sight. Crazy, huh? But I don't need a pickup. Elon, PLEASE, PLEASE make a "CYBER SUV".... 8-passenger... you can leverage off the CyberTruck platform!! (same as model3>y, same as Rivian p'up>suv, same as Silverado>Tahoe)... can be built on the same assembly line. Someone needs to do a render of what a CyberTruck would look like if was an SUV (with LOTS of headroom for all rear passengers). Sorry for the long post, love your channel! :)

Great video. You should do a video on the new solar technology being developed by the British company "Cambridge Photon Technology" (CPT), who have been published in Nature Science journal. They are working on a transparent layer which could be placed over EXISTING solar panels, and this layer makes use energy from different parts of the light wavelength which are not used at all by normal solar panels, and it converts that otherwise unusable range into EXTRA photons of light that can be used, and passes those, along with the other light, onto the solar panel below. In brief, it does this by converting the normally unusable light into pairs of excitons which, via quantum dots, then causes the film to emit lower energy photons that the solar panels CAN then use in addition to the normal light bands the current do. This can effectively potentially double or more the efficiency of existing solar panels! Solar is already the cheapest way of making electricity, but if we can DOUBLE the amount of energy generated in by the same area of panels, then it would, when paired with batteries to make the energy available 24/7, change the world overnight to 100% renewable, clean, cheap and limitless energy.
As the saying goes "If God had wanted us to have clean and limitless free energy then God would have put a huge nuclear fusion reactor in the sky... oh wait, God already did that, we call it the Sun!" Solar power is a way of simply using the same natural nuclear fusion energy that has provided the energy for all life on Earth, via heat and photosynthesis - so as all of life's energy comes from the Sun, it makes sense that ALL our energy should come from the same eternally reliable source!

I'll start off by saying I am a stock and reservation holder. But, purely there was a bait and switch or an imature initial promise (which might look like a bait and switch as time and ability goes by). I identify with these reasons for buying the car: safety, environment, maintenance, cool tech. I believe most buyers have that in their mind in some order. The final and controlling factor is cost.
For me, I believe that more cars could have been produced and delivered at a higher profit percentage (not dollar amount) if the packaged car would have been or would be the base battery, auto pilot package, and premium package. Then add the all-wheek drive, and performance package and lastly the extended battery option. If battery production was an issues (as stated at one point during production) fewer batteries would have been needed to produce more cars equiped with the highest profit margin options. Greater economies of scale would have been realized on more parts and production sunk cost.
Last thought: there is a reputation cost that has suffered. The thinking is better than other car manufacturers, the process although adequate, could have been better, and will improve... so I remain long and hopeful for the company.

Hey, love the video. Honestly so much good information!
I think Hydrogen and BEVs dont need to smash each other. I think about it like Diesel and Gasoline. Both have their pros and cons.
BEVs might be the sporty consumers favourite as well as commuters who rarely need to go above 100km a day. If they want to, there will be fast charging available!
Buisinesses could even rent out some of their BEV fleets battery capacity to the grid companys to use for energy storage if they dont need it.
Trucking companys and commuters that need to travel long distances might prefer they way faster refueling and higher range! (As well as obviously flight and shipping companys prefer the high energy density. For planes especially so, due to Hydrogen being used making the plane lighter, where as discharged batteries become dead mass.)
Also I think it is likely that grid companys will have to put steep prices on fast charging at peak times when BEVs are commonplace because it can really destabilze a grid if too many charge at once during peak power consumption. Maybe this even leads to new natural gas power plants being build to compensate. This is obviously the opposite of what "emmisson free vehicle" is supposed to mean. While Hydrogen could be made with PEM during nighttime between 1:00 AM and 5:00 AM where the power consumtion is really low. This would stabilize the grid and could lead to fossil power plants closing down.
So to be frank a COMBINATION of the two really could make zero emission transport for goods and people possible!
Also I dont like some of the fierce "I'm right, you are wrong", here in the comments. Relax stay neutral and think about whats best for the planet!
It is our future and we need calm minds to prevail, not some hotheads blowing steam.
If anyone ever reads this and thinks about it, thank you so much.
And if you can support Two Bit da Vinci, do it, because I'm a student and I really can't.
Have a nice day!
Ludwig

That was a fun breakdown. I have followed all these companies. We are on our second Prius. We have had it for eleven years. 165,000 miles. 46 mpg. We drive mostly highway speeds.60-80. We have our cosmetic issues such as paint peeling, monitor screen for navigation burning out, things falling apart on the inside and some other oddities. So, I think we paid top dollar then. My guess is it has cost us under $2000 a year. Battery is fine. I meet people with 300,000 miles on their Priuses and they are happy. My old 1979 Cadillac with a 475 cid gave me 12 mpg and I was happy at the time. It had to go to the boneyard with 275,000 miles in 1992 because of frame rot. A 300 mile range is the minimum that makes any sense. Leaf, Smart and the other low miles electrics just gave people the jitters if they were stuck too far away from civilization with no place to charge. If the Chevy Volt could up the electric miles from 38/48 to 60 or 75, I think it would be a great transition car. I know lots of Volt owners that barely use the gasoline. Funny people? Yup. I drove the new Bolt. It is okay. No, it is not like the Tesla. The one I drove retailed for $43,000. 210 for range. I commend ALL MANUFACTURERS for doing their best. Thank you Two Bit da Vinci. Congratulations on your upper income success!

Hi, the Tesla Model Y 7-seater is the first Tesla I ordered, the very day it was announced. Months later, when I finally test-drove it with my spouse + 3 kids (11, 13, 19 years old), it became obvious that the 2nd row was too cramped for them to coexist. There was fighting almost right away. If not for that, it would have been a contender. Our needs for many seats is mostly in town (grandparents coming over, all 7 of us want to go somewhere) or there's a soccer practice or kids birthday party. However, for longer roadtrips, with 5+ people and their luggage, this car is just too small. So, we got the Model X, back when it was $75K or so, and haven't looked back. It can sit 5 or 6 people comfortably and haul some decent amount of luggage. There's just a few more inches in every direction.

Hi, I enjoyed watching you uTube video & especially that you included a narrative of the prices, costs & benefits. So thank you for your presentation & I will look forward to a further update on your PV system & progress in future years.
You live in a sunny part of the USA & I reside in the UK (Colchester), at my latitude we do not receive any where near as much sunshine & the weather is cooler, more temperate & cloudier. In October of 2011 I had a 4-kwp system installed on the roof of my house & have since added a few more PV panels to squeeze 5.75 kwp through a 4-kwp inverter. I'll try & give you some maths (as I was so impressed with yours). System cost just over £12,841 in total, but I keep adding to it & tweaking it (I can't seem to help myself - lol). Included in this cost are two Immersun units, two 110v transformers & three power halvers. These help me more fully utilise the power when it's available without importing much electricity from the grid. We don't have net metering here (sob) but we do have a subsidised Feed-in-Tariff, I don't have any export meter either. The FIT income averages around £2,500 pa & it saves me about £350 pa of direct electricity costs. My system paid for itself in 4.95 years & over the 25-years of FIT it should yield an IRR of 21.6% pa. My annual electricity imports are now down to around 125 kwhs pa costing a mere £20 pa on a zero standing charge tariff. Most people don't believe this, however I have the bills & FIT statements to prove these figures. The system generates around 5,000 kwhs pa. I have a very detailed spreadsheet which auto-calculates the discounted cash-flows & income / savings budgeted & compares them to actuals. It also calculates the projected IRR, (I used to work as a cost analyst). The reason my imported electricity bill is so ridiculously low, is that I have gone mad on installing insulation: cavity wall insulation, double thickness loft insulation, triple glazed windows & I will hopefully this summer install insulation under the ground floorboards (horrible job). I also live quite an alternative type of lifestyle, so I live a green & frugal lifestyle.
Just thought I'd show to your readers that there are benefits wherever you live in the world to trying to live a greener & more environmentally conscious way of life. I hope this comment helps someone out there.
Regards to all,
JohnnyK.

Hi Ricky. Love your channel. Anyway, early in this video you mention the argument that too many EV's will overtax the grid and that you would make a video on this issue should the viewers request it. I'm officially request you research and bring us an analysis. I'm and EV owner as well as a solar and storage owner, so I feel like I am doing my best to offset my grid impact. For those sounding the alarm of EV grid stress, I wonder why I never see these issues discussed in editorials, YouTube videos, letters to the editor etc when a new 1000 home subdivision is built, a mega casino, large apartment buildings, shopping centers complete with Walmart and Home Depot etc, (well you get the picture) pop up around cities and towns all over the country and world. It certainly seems to me that all of my examples would have a much larger impact and for a longer sustained duration than the few hours per day of low kW charging rates and time that most EV's use. So, yes, please do a video on this. Thanks!

Very well done video on the new Lightning. I've been interested in electric cars since Morrison came out with his back in the late 1800's. The high torque at zero rpm was always a big plus. When Toyota came out with their Prius hybrid, I thought that was a good idea, especially when gas went up to $5/gal, plus the hybrids had a huge range and there was no one hour wait at a charger. But then the question of battery life came up after several years. 8-10 years and you need a new $2.5k to $4k battery, or if you knew how to do it, you could get a used or refurbished one much cheaper but with a reduced life time. And this is with a hybrid system. A pure electric system might have a worse life and judging by the size of the battery in this truck, it has to cost way more than a Prius battery. This subject is seldom mentioned when discussing costs to operate these electric vehicles and probably never mentioned by anybody at Fords. You mention that there is almost no maintenance required on this Lightning, which is probably true, but at a certain amount of miles, it's going to need a new, very expensive battery. Back in the 60's, Ford ran an inline 6 cyl gas engine continually in a test fixture for one million miles. I know many people that have Ford pickups with more than five hundred thousand miles on the original engine. Yes they required the usual maintenance and maybe a few replaced a transmission for $2k, but not 3 or 4 expensive batteries. Having to fork out maybe $6k for a new battery every 100k-150k miles for this Lightning, which I personally think is a fantastic F150, may be a possible turn off for prospective buyers. It is for me.

I understand the rationale behind a lighter hydrogen drive train allowing more cargo to be carried, increasing profit per mile, but I wonder how that will measure up against the higher cost of hydrogen, which also scales per mile.
If we assume that the Tesla Semi takes ~2 kWh/mile (Tesla says it will take less, but didn't cite a more specific number, so we'll err on the side of caution) and the Model 3 and S take 1/4 to 1/3 kWh per mile, we can expect a hydrogen semi to similarly take 6-8x as much as a more conventional passenger vehicle (currently $.22/mile). Multiply that out and we've got $1.32 to $1.76 per mile for a hydrogen semi. A bit of Googling suggests that diesel can cost $0.54/mile for a typical semi (out of a total average cost of $1.38/mile for all expenses, including wages and maintenance). And a semi can drive 2000-3000 miles a week, which we'll average to 130,000 miles per year.
If we crunch the numbers and are optimistic for hydrogen, the extra 78 cents per mile adds up to $101,400 per year compared to a diesel truck. Maybe improvements to aerodynamics and hydrogen refining will help bring that down, but on the surface it doesn't look promising compared to the status quo. In comparison, Tesla hopes to match or beat the cost of diesel semis (though to be fair, this assumes Tesla providing the power at a very low price, which I'd say is a bit optimistic for the near future).

Two things, and this is just a very general explanation of a common, long freight train, not necessarily the one involved in this tragedy. One is that (very generally speaking) the multiple brake shoes per car are the same size, on the same size wheels, on almost all train cars despite how heavy they might be. Therefore, a lighter-loaded car might come to a halt quicker but heavier cars behind it keep surging forward, not yet able to come to a full stop as quickly.
The other factor is the very nature of how the train brakes work, which is via a compressed air line that begins at the diesel locomotive(s) and runs all the way to the last car. If an engineer executes an emergency stop, he or she releases the compressed air which begins to engage the brakes almost instantly on the locomotive, then very quickly on some of the cars right behind the locomotive, then taking a little longer on the cars further back, and so on down the line. On these huge 1-2 mile long trains, it simply takes time for the compressed air to gush out of the line and clamp the brake shoes on the cars furthest back. Therefore, the longer the train, the more parts of it keep plowing ahead before the brakes take effect.

Brilliant vid Ricky, as always. 👍
An Aussie here, with the bulk of my working life, spent in our State government-run essential services electricity supply industry.
In the latter stage of my career (late last century), the government was adamant that electricity prices would be cheaper for all consumers if the industry went private instead of being publicly owned/run.
That was the biggest con job ever.
Needless to say, my career ended early due to health reasons aged 48, electricity prices have escalated & reliability plummeted. Who would've thought? 🙄
Back on topic, we went solar about 9 years ago because it made sense, & also to give the lie of privatisation the bird.
Payback was instantaneous & we've saved money from those 9 years of going solar.
Installed vacuum-tube solar hot water in 2014 & highly recommend others do that too.
Your mention of base-load generation & gas turbines being used to cover peaks is also on the money.
Not good for the hip pocket, & definitely not for the environment.
In closing, electricity suppliers should subsidise consumers that have solar & triple it for those with storage.
Let me dream. 😉

Ordered the AWD as a retirement toy. For me, this is a once in a lifetime purchase. I love that there is no PAINT JOB to worry about, and it has massive tires, with elbow-high wheel wells. It's ALL BUSINESS. I won't be towing or carrying much to be honest. To me... it's an EV FIRST and a TRUCK, second. I don't drive very much, so the extra energy required above and beyond the model 3 or Y is not much of a big deal. I would get the solar panels, because it will sit in the sun all day long. But.... can the "jaws of life" extract me from this thing, if ever needed? Is it capable of V2G to power my house in case of a power failure? I would never buy it without driving it first, but I am probably @ 60,000th in line, so there will plenty of time to drive one before i must commit.

I was 7 years old when I watched Neil Armstrong as he lumbered down the ladder of "The Lunar Landing Module," (L.L.M.,) & on the last rung, He paused and uttered those immortal words, "That's One Small Step For ("A,") Man, One Giant Leap For Mankind." (If you've never heard & you don't what The "A" In Parentheses is all about, Armstrong's actual words were "THAT'S ONE SMALL STEP FOR 'A MAN',,,Etc." A Glitch In The Radio Signal Covered Up The "A," so those of us earth-bound people didn't hear The "A," & to this day not a lot of Earthlings know about the error caused by 1960's Radio Technology.) Hopefully, when we make it back to Lunar Surface, we'll hear every word in Stereophonic Clarity! We were told that by the time that we were grown, that we'd be taking Moon Vacations as easily as we took took any Earth Vacation by Airplane. Personally, I was in love with The Space Shuttle! The Launches & Landings were spectacularly beautiful! My Late-Wife's First Cousin was Judith Reznik, The NASA Astronaut on Her Second Shuttle Flight on Challenger when it Exploded 113 Seconds after Launch on January 28th, 1986. I had applied & accepted to be a Mission Specialist on A Shuttle Mission. I was a Licensed Jet Pilot, and I looked forward to flying higher & faster than ever before. I had even been through The Astronaut Training Program, but The Mission, which included My Mission on The Flight was Permanently Scrubbed. I applied Two More Times but I was never selected. The Shuttle was permanently retired and I am getting a little long in The Tooth for NASA to consider me for a Mission NOW. My only hope for reaching the 64 mile mark, (100 Kilometers,) The Edge Of Space is in one of The Private Passenger Space Planes being designed by various Individuals and Corporations. I'm surprised that they're not taking people for the flight of a lifetime yet! (Yes, I'll spend My Kid's Inheritance for The Chance To See The World From Space, even if it is just for a few minutes!) Technically Speaking, on Earth, We've reached a point that we imagined when we were kids. Virtually every Home Has At Least One Computer, Cars Are Equipped With Computers, And There's A Computer In Everyone's Pocket! Cars Can Drive Themselves, (and I Once Thought that "Cruise Control" was High Tech. LOL) Drones Now Fight Our Wars, Most Anyone Who Wants One Can Own Their Own Drone For Aerial Photography or To Spy On The Beautiful Gal Nextdoor That Sunbathes By Their Pool Topless. Drones Now Deliver The Stuff That You Order Off Of The Internet, Drone Cars Now Deliver Your Pizzas, Drone Ships Collect Spent Rocket Stages After A Space Launch From K.S.C. If You Get Lost, Your Smartphone, ("The Computer In Your Pocket,") Can Tell You Where You Are & How To Get To Where You Want To Go Using "Global Positioning Satellites," (G.P.S.) We live in a High Tech. World, A Robotic Vacuum Cleaner Cleans Many People's Homes, Though The Humanlike Robots are still some decades away, Robots Are Beginning To Become More Common In Places That Couldn't Have Even Been Imagined Just A Few Years Ago. Oh, And About The Flying Car Thing. Don't Hold Your Breath! One day, We May Use Hovercraft Motor Vehicles instead cars sitting on Four Tires, But Take It For A Long Time Pilot, Flying Cars Are Just NOT Feasible! Just As The Weather Grounds & Airplane Flights, It Would Also Ground Your Flying Car! Your Boss Would Likely Not Be Very Understanding If You Couldn't Make It To Work Because The Weather Grounded Your Flying Car!
However, Back To Space Travel! I'm Disappointed That We Didn't Replace The Space Shuttles with a more Up-To-Date Design. I feel like in many ways We've reverted back to 1960's Technology. However, if it'll move us forward in Human Space Exploration, They can get to Space By Helium Balloons for all I care! I look forward to our return to The Moon. I will be just as excited as I was between 1969 & 1972 when We sent The Original Lunar "Bunny Hoppers" to The Moon. But that happened in the Early Years Of My Life, and Before I Leave This World, I Want To Live To See Humans Set Foot On Mars! That'll Be The Ultimate In Human Space Travel For A Lifetime!!!

Maybe I am missing something. But from the drawings that you overlayed, the walls and columns only extend halfway into the street, but not into the buildings across the way, as long as you omit the elaborate stairs. Having a grand cathedral in the middle of empty fields meant that they could extend the design for the stairs, fountains, outbuildings and gardens out a great distance. Sure, getting a longer distant view of the incredible cathedral would allow you to take in the amazing scale and grandeur of the building. But in the reality of a modern city, property owners in the surrounding areas are not likely to tear down their profitable businesses and housing just for broad and impressive staircases. It seems to me to be a reasonable compromise to close off the street, finish the columns and spires, build less expansive stairs, and call it done.

Tell us all, how many Hp and Nm do these 100 electric motor appliances in your household produce? With the Tesla motors, it's just wear and tear, in 99% of cases the bearings fail and as they are not a user replaceable item, Tesla replaces the whole unit and sends the faulty one back to the factory. Also, as you mention very complicated ICE cars, I had 30+ years old cars, that had the original engine, gearbox and differential. Now, how to prove what I say? My word is as good as yours, and you may only search the internet. I do not own a Tesla and even if I did, you would not believe what I say.
Also Tesla cars are heavy, so all the suspension componets die prematurely and the AWD versions have issues with the front end due to weak drive train. Once again, your 100 electric motor appliances do not move around 2 tons and do not output several hundreds of Hp and Nm. It's all a matter of scale.

Funny that this one is coming out now. I bought a radiant stove a few years ago to replace a coil electric and have hated it since we bought it. The inability to control cooking temperature combined with a really bad oven that won't hold temps has driven me to look for a new gas stove. Nothing I've used has come anywhere close to giving me the temperature control I've had with gas with old coil electric coming in second. I'd like to try induction, but these appliances are expensive and I can't buy one to just try it. Buying a cheap one wouldn't be a fair comparison for the tech. Besides, induction may be great for a cooktop, but my oven will still have to be something else and modern electric ovens just seem to all be designed for convection, not for baking with no blasted fan running. So again, gas... Flame away folks, I'm going to have to go to gas again for equality of life reasons.
On a slightly divergent note, has anyone looked at air quality when there is a mix of gas and hydrogen, like they are experimenting with in the UK? We could debate the merits of an even more reactive gas being used, but I'm more curious about the effects on air quality given the current debate,
Live long and prosper. Yeah I saw that!

Excellent video, thanks a lot!
As you mentioned, we are comparing here two different technologies of different maturity levels. Hydrogen has still a lot to improve... I am confident that hydrogen will take off, not thanks to cars but other applications, and then, eventually will reach personal vehicles.
Everything that move us away from polluting solutions is GREAT!
A few notes to go further: in your numbers, I would have taken into account manufacturing, not just usage. Good videos on YT about it. For ex, for the first years a Tesla is more polluting than a gasoline car, but if used a long time it is greener. In addition, we move the pollution from usage point to mining and refining points (-> in poor countries, which is rather unfair).

Hey Two-Bit DV: Really like your stuff, but here my main concern with this comparison, is that you're using a Model 3 that does not yet exist: The literally still-non-existent "base" $35,000 model. As I'm sure you know, the actual, cheapest Model 3 built so far, that people can buy, is the $49,000 "First Production" model (in black - add $1,000 for any other color). I know you made this video well before it became apparent that there would be no base $35k model available for a long time, but I think it would be useful to update it, to reflect what people can actually get, which is the $49k First Production model (Premium upgrade package, and Long Range 310 Mile battery mandatory/included). You might as well throw in another $1,000 (to get to $50,000), since you pay that extra for anything other than the color black) As such, it's difficult to utilize your comparison, since it's using a car that literally does not yet exist.
BTW, I have a Model 3, First Production, it's utterly amazing, and I'd get it again even if it wasn't the cheapest TCO in any comparison, and I viewed your video just to see how it fares against comparable ICE cars. But . . . .since the Model 3 in your comparison is literally still a Unicorn, and comes in at a full $15k less than anyone else could buy it for, I really wasn't able to assess how an actual, obtainable Model 3 would compare. (I get full rebates, so my actual cost, before tax, is $39,500 - i.e., $50k minus: $500 local electric utility rebate, $2500 CA rebate, $7500 Fed Tax credit).

Can't wait to watch your progress. I'm on a similar path with a 20-year-old all-electric, 2900 sq ft house in Central Texas. Started in 2010 with a radiant barrier, additional attic insulation, and two air-source heat pumps. In about 2014 replaced the conventional electric water heater with an air-source heat pump water heater. In 2018, replaced the composition roof with standing seam metal (galvalume) and added an 11.4 kW solar array. The solar array is bolted onto the standing seam metal roof, so there is no roof penetration for the solar. I've replaced most of the windows with low-E, double pane, synthetic frame windows. The next step is battery backup. I'm planning to go with an Enphase system because: 1) already have compatible Enphase micro-inverters on the solar panels, 2) LFP battery chemistry vs NCM and 3) the Enphase system creates a whole-house micro-grid when the grid is down. After batteries I'm planning to add rainwater capture. Ground source heat pump is also under consideration when the current heat pumps need replacement.
Re: Heat pumps ... If you are already planning to drill a well you should do a deep dive into ground source heat pumps for heating, A/C, and pool heating. Based on the minimum possible research (Symbiont Service Corp Youtube channel) it looks like you can combine central heat, A/C, hot water, and pool heat with a closed-loop ground source heat pump and a lot of plumbing. Also, no plumbing on the roof. You could even include hot water for the Studio House.

I just watched this watching your video on the recent fires and ongoing devastation in Hawaii. Talk about a deja vu. Shudder. My heart so goes out to the Hawaiian people. But also to the others who've had terrible fires this year, eg, here in Canada, and others. Then there have been so many floods, and just the past couple of days landslides in India. I'm nearly 70 years old and i definitely notice changes in weather, etc. It's definitely warmer in the winters here in Ontario, Canada, than it used to be, for the most part. Summers...not sure. It seems hotter sometimes, sometimes less so. I think we're getting more cloud cover now than we used to, even before our fires in 2023. Thank you for all the info you pull together and altho it's fast, I can follow it. Really appreciate it. (am typing with broken arm, so excuse any errors.

This type of comparison is why it's Game Over (long term) for ICE cars. Good video. Having said that, there is a HUGE market Tesla will not tap until they get the (all in) price under $30K. For example, I've always driven small cars costing under about $20K, and I am most definitely NOT alone. Many simply can't afford much more than, say, $20K - $25K for a vehicle, and others (I'm one) are able to buy more expensive cars, but don't, seeing it as a waste of money, even accounting for cheaper operating costs, because such buyers look for the most economical way to reliably meet their transportation needs, which is typically not in the $40K+ realm.

Experts has always under-estimated change. And when it comes to AI, just look at what happened w chess and Go. W enough varied and quality data the progress always surprises on the upside.
I agree, competition is going to come from AI companies like Google, Apple, Amazon, CommaAI, Microsoft, etc.
Legacy auto will not be able to compete on price w ICE based robotaxis and higher prices solutions added to their vehicles.
I think you are missing the cost aspect here. Technology wise, there will be competition. Tesla is following Apples script. And if legacy auto + some AI company is Android, they will be fighting for the crumbs (un terms of profitability).
Teslas advantage w EV and Autonomy is more cost than technology. 4680 tabless dry-electride high silicone anode cells and castings w structural pack will give Tesla a tech advantage again.
Teslas FSD computer is a specific solution that is efficient, optimal and cheap. The rest if the industry use power-hungry inefficient general purpose solutions from NVIDIA (and possibly others). Their power consumption is too high to work in EVs and their cooling requirements are not practical for a mobile solution.
Designing a chip like Teslas is easy and anyone can do it (and they only designed a small part if it). But you need demand for a million units to make it cost effective.
No one will do it bcz they think Teslas solution won't work. Once Tesla has proven their solution others will follow.
As for regulations, if the cars prove safe enough they won't require more safety devices. But over time there will be changes. The one sure thing is hardware requirements will change over time. However not one regulator makes all the decisions, so Tesla could operate in many places under different requirements/regulations.
Cars won't have to communicate like air traffic control. Humans don't have central control today and we drive pretty good Planes is a bad comparison to cars in this respect.
There already are 'exams' autonomous cars have to pass to get licensed. The 'eye exam' is another bad example and irrelevant. I think the test requires prove of driving accident free for x hours and y miles. If you can do that, it means the sensors are up to scratch.
Humans sit just in front if the B pillar and can manage fine. Yes, wr can lean forward, but you assume Tesla engineers would have made this elementary mistake is reaching IMO. I believe the side-vision issue is more a NN/AI or processing issue (not all the cameras are running on their own NN currently but it is coming w v9) and not a vision/sight issue.
Good vid overall and solid roundup of relevant issues/ideas.

Another though provoking topic, well presented. Unintended consequences is on of my biggest issues with 'big government' and more regulation being the 'go to' answer. (Though it needs to remain in the toolbox when deregulation yields the same.)
Overall, I agree days of ICE are numbered (at the poles and on the road). It's well know in the markets, academia as well as the Oil Industry. Bloomberg New Energy and countless other have given a timetable similar to what you mentioned. My point being, LONG TERM FOR THESE GUYS IS 5-YEARS. If you can't win, you delay and try to squeeze every last dime out of the current system. Look at Trump's horizon - about 5-years as well without some sort of coup or other political upheaval. (Though I'm not dismissing this as a possibility.)
Executives doing things for short-term profits - i.e. their pockets vs. long term health of the company (and in this case is the world), is closer to a norm than an exception. Under the covers and above, expect further support for both autos and fossil fuel to get more subsidies, bailouts and handouts.
In a previous reply, I mentioned I didn't expect the 'current regime' to go away quietly - or with empty pockets. Call it confirmation bias, or 'correct call' - readers choice.
Essentially, Pandora is out of the box and markets take no prisoners. Beyond the standard transmission high performance cars you pined in past videos, I will shed no tears.
Stay safe one and all!

Balloons as Weapons
What a paradigm changing concept of using a balloon to further political/military strategies and tactics. Multiple waves of balloons, their 3 CONEX containers full of S300 'switchblades' to launch an Island invasion.
First wave, drop over the island, absorb/consume/overwhelm the defensive weaponry and exhaust the defenders.
Second wave, drop over the island to create civilian panic, disruptions and absorb the remaining defenses.
Third wave to target seaborne defenses.
Fourth wave to cover the offensive ICBMs and seaborne invasion armada.
Offensive benefits: cheap, low tech, hard to defeat, defense draining resources, minimal risk and minimal loss of personnel/materiel, excellent cover for invasion forces
Defensive challenges: expensive, hard to target swarm, hard to defend against swarm, exhausting, arms depleting, excellent cover for aggressor.
Sun Tzu and Clausewitz would be proud.

Comments :
-This video was interesting. I follow a lot of things about space, and I still learned enought to make it fun to watch. I did not consider anything about the size, or economies.
-Why is the thermal scale (boiling point) from top to bottom ? That's confusing as fuck. You either need to put an axis, or stay with the standard 0K on bottom. I know that when programing usually the vertical axis origin is on top, but honnestly that too is pain in the ass except with good APIs.
-The starting thing about gravity and equation leads to wrong interpretation. That's not because satellites/starship are in high in Low earth orbit, so gravity is smaller that they don't have to have lot of fuel. Earth radius is 6300km. LEO is somewhere from 160km to 1000km. So taking the "big" number is like 6300km to 7300km, leading to a decrease of only ~30% (i.e. on earth surface, gravity is 30% more than at 1000km altitude).
The key here is being in ORBIT which is moving REALLY fast without anything to push (no air to propel yourself). Thus you rely only on newton's third law, and propulsing your own mass (fuel combustion byproducts) with. That's why when talking about space travel, you are not talking about distances, nor time, but about the speed change you have to achieve (delta-v) for a given path. I don't remember the exact numbers, but getting to orbit a body is like half the power (delta-v) needed to get away from it NO MATTER the gravity, or object mass. Thus, once in orbit, as you jettisoned all conteners and fuel to get there, you don't even have to get the same work to go away.
I did some research for illustration purposes, according to wikipedia, LEO is around 7.8km/s orbital velocity. And earth escape velocity (speed needed to escape earth gravity) is 11km/s. Thus, going into earth orbit is like doing 2/3 of the job (delta-v you remember ?) before escaping its gravity (that's why you jettison first stages, and second stages). Fun fact : I did not know anything about this like 4 years ago before playing kerbal space program. That's where I learned that orbital physic, manoeuvers and shit are REALLY REALLY different from physic on earth, even if that's the same underlying equations. When considering orbital manoeuvers, especially if you consider the earth point of view, you are not in a newtonian model anymore.
That's confusing, and beautifull. And complicated. Especially when talking about gravity assists.

I really like your vids, how you mount things and show related to what you're saying. Keep your good job.
On your topic, I think there may be lots of changes on long term about commute reduction, work at home and everything. But I don't think things are going to change to point where big oil companies will ALL go bankrupt. I think what will happen is that lots of oil companies will bankrupt, then offer will shrink. It will lead to prices going up (not to what they where like, but up), and then things will repeat themselves, just not to what we were used to.
It may even be better : we move to EV, and as oil prices are low, governements can start building oil plants for EVs. Even if that's not totally green, it may be greener than having lots of inefficients motors on cars. (bigger plants = bigger efficiencies, EV = bigger efficiencies). Maybe I'm wrong, but that may be an answer.

A lot of these are things I'd be highly interested in whenever my wife and I build a new house. As it stands, I live in a house where everything - the plumbing, wiring, doors/windows, and even the physical construction of the house - was built/setup by my dad years ago when he was maybe 20-21 years old (my dad built this entire house with the help of his dad and grandpa who was a stonemason and rocked the entire house) - and he was also an alcoholic at the time. He gave his brother a 30 pack of beer to help him build the laundry room in a weekend. I mean, I'm 36 years old now and he built it when I was only a year or two old and it's still standing and I've lived here since 2009 but everything is just built in such a way where stuff is starting to get old and rickety, out of square, floor joists and wall studs are starting to give way and it's just where it would be hard to upgrade stuff. I feel like a clean slate with a new house someday and I'll get back to home improvement stuff - hell I miss doing home improvement projects. I worked on this house all the time when I first moved in. But it's just too far gone at this point. It's a good starter house, bachelor pad, emergency/hard times living quarters, etc. though.

so, This NEEDS to be said. efficiency and what is ultimately better is a much more complex answer than simply switching your stove. i understand the environmental push and everyone wants a greener solution, but please don't mislead the audience on limited facts. ANY electric stove is 100% efficient - but... the electricity getting to the stove is far from it. Generation is usually lower voltages 5-24kv and then losses occur at the initial step up transformer (GSU). voltages are again boosted across TRANSMISSION for distances and lower losses. Then again, its stepped down to a distribution transformer (4-13kv) to be transported by local poles in your neighborhood. At last, its stepped down AGAIN to your common household voltages 120-240 ,by way of pole transformer. EVERY transformer has loss, every connection has loss, and it's exceptionally hard to answer how much, short of all data points. Gas has similar setup, but the actual GAS itself is not lost.(i don't want to get into natural gas transmission) is one or another better for the environment? honestly -i don't think we have crossed that point yet. If your mission is pure green and efficiency then pick up a MICRO Combustion turbine (multi-stage or burn) and use natural gas to generate your own electricity. its a demand as need setup, and burns the cleanest of any fuel. But this is impractical and sadly most people continue to think an electric stove is better for the environment without looking at every aspect that's involved.

This ONLY works in CA where electric costs are so high. CA does this to force you into China solar panels. In Michigan, I'm paying 16 cents per kilowatt hr. My break-even (you strangely call this buy back) would be double what yours is. 17 years??!
Also, my home was built in 2020, I likely use less electric than you do, thus it would take me even longer to break even, because if we both used zero, you'd never break even.
I promise, if you had put $10k into the stock market 10 years ago, you'd have $30,000 vs saving $10,000. That's a $20,000 difference.
Id go solar if it paid itself back in about 4-5 years, not nearly 20. It's neat, but the up front cost is way way too high.

the finnish company doing the sand battery I think is on the right path... you just have to improve insulation around it and then pump as much heat as you can in when the existence of it, or power to generate it, is available... They all talk about excess renewable energy... yeah, they curtail some from the grid but there's not that much yet... sand, steel plate stacks, even crushed rock and molten salts all have some viability as heat sink storage... heat to recover - and in this system to aid in the re-gasification phase... There's a great energy flow map that LLNL puts out each year with flow from raw to end use / rejected heat... any heat source contributing to that 65% waste/reject end point is a potential source ... just under .25 of those points come from electrical generation... trap and store some of that at those generation points and use for space heating, or this sort of re-gasification, or frankly Stirling engines to generate more power from... where there's waste, there's opportunity. But in the end, nothing is going to add more power back than properly insulating, processes, homes, businesses and optimizing to use the best HVAC, motors and pumps... that stuff is all substantial incremental sources of nega-watts that you never need to alter the grid to add back... same with behind the meter solar panels on homes... Such a great challenge out there, and ripe for the picking over a decade of focused effort...

Your science of the ozone layer is quite a bit off. First off the ozone in the ozone layer has a half life of about 3 days. If it stops being produced it will be gone in a couple weeks, no CFCs needed. The UVC in sunlight is what creates it, and in large amounts, enough to continuously replenish the natural decay. The amount of UVC hitting the atmosphere is enough to produce way more ozone than we see because the ozone produced in the upper atmosphere is enough to shield the lower layers, it is in equilibrium. The concentration of ozone is directly proportional to the intensity of sunlight, more sunlight, more ozone, less sunlight, less ozone. As a matter of fact the concentration of ozone above you decreases every night and goes back up in the morning. Since the polar regions have months without any sunlight, the ozone completely disappears over the poles every year, a real live "hole in the ozone layer" but it is completely natural. The south pole is worse because it gets much colder (no ocean under Antarctica) this causes microscopic ice crystals to form in the upper atmosphere which act as catalysts ripping ozone apart, thus the south polar "hole" takes a lot longer to recover in the spring, the air has to heat up enough for the ice to melt. This equilibrium of ozone and sunlight is a buffered system, you can increase the ozone decay rate (such as from CFCs) and it makes very little difference. The problem is that if the decay rate gets high enough to be greater than the rate sunlight can create it the system goes out of equilibrium and the entire ozone layer would be gone in a few weeks and there would be nothing we could do to stop it. The amazing thing here is that the response was swift and effective. And probably DID save the human race. Even though almost everyone had (and still does) a completely wrong idea of what is going on. BTW CFCs and cousins are completely unreactive with ozone, the problem is they are so stable they slowly float into the upper atmosphere where the UVC is much higher intensity and that rips the molecule apart freeing the flourine, which is a catalyst that destroys ozone. So we replace an incredibly stable molecule (otherwise known as "safe" compound, you can breath it, eat it and it doesn't harm you) with things that are slightly harmful but get destroyed in the lower atmosphere were the by products can't harm ozone.

Only just found you - very impressed and subscribed. I particularly liked the basketball court image - even a space nerd like me didn't realise just how big Starship is!
But, I do have one worry about all this. Starship (+SH), amazing as it is, is still 'only' a means of transport, and, as long as it is justified by reference to Mars colinisation, we need to bear in mind that there's a hell of a lot more to simply getting people to Mars, let alone living there long-term. Leaving aside problems like getting Starship human-rated, and developing the massive life-support systems that will be required, there's the radiation (not just on the way, but on Mars itself), the poisionous soil (no growing potatoes in that!), and all the technical difficulties of fuel manufacture, habitat construction, etc, and, of course, the cost (Starlink isn't going to pay for all this!) - never mind the politics! But, most significant of all, there's the gravity - or rather the lack of it. And I don't mean just on the way there and back (although that long in zero-G is bad enough), but on Mars itself. We have evolved over millions of years in a 1G environment, and it's highly unlikely that we'll be able to survive long-term in a 1/3G one. Maybe we'll be able to cope with it for months or even years (although returning to 1G after years on Mars could literally be lethal), but I seriously doubt that we'll be able to colonise Mars because we won't be able to conceive and raise children there. Don't mention this to Musk, because I'm enjoying the Starship ride, but I don't think we ever will be a multi-planet species. We are Earthborn, and, I'm afraid, it will turn out that we also Earthbound.

How come the Bolt is rated at 200HP, and only go 91MPH?
For reference, my Ford Fiesta ST, is rated at 180HP on 87 octane fuel, and 200LB ft of torque,
It does 0-60 in 7 seconds, and has a top speed of 145MPH.
So while I believe the Torque rating, I seriously doubt the HP rating.
HP on a gasoline car is a good indicator of top speed, but on an electric car drops as MPH goes higher.
In that sense, they should have suggested that the Bolt has about 70-75HP, as that's much closer to the same top speed as a smart for two...
The torque sounds about right. The bolt has a lot more torque, but also a much higher weight.

Ricky: I have enjoyed all of your videos that I have watched. I guess you could call me a frustrated hippie, I graduated H S in 69 but became an engineer. However, I have always had this Mother Earth News side to me, thinking about how to do things better. Elon has the drive and the resources to do what I would have loved to. He has a company that can quickly put together needed items like the ventilators. Very admirable. However, don''t ever think that the old U S industrial giants can't do the same thing. I was part of that for many years, there are a lot of forward thinking highly intelligent people working for old school companies ran by bean counters. The fastest way to drive innovation out of a company is to put a bean counter (Roger Smith) in charge. However, rewind to WWII, the arsenal of democracy. Ford, GM, Chrysler, and the rest of the industrial base of the US won that war. That get it done spirit is still there, as witnessed by the call to arms issued as a response to our latest crisis. Tesla was not the only company that jumped on the bandwagon. Living near Detroit, which was the center of the arsenal of democracy, that same spirit was alive and well in Michigan's commercial and industrial companies. With the right leadership, these organizations can perform equally as well as Tesla, we need to clone Elon to lead more of our companies and get government out of the way and let these companies fly. Challenge them, they will excel. I don't blame you for your admiration of Tesla, I'm with you. Just don't count out the US industries, I know what they can do.

Thank you again Ricky for your fabulously thought-provoking videos, the Iron-Air batteries seem ideal as base-load supplies, the exact area where fossil fuel plants still find their place, even with solar & wind.
However, the low power density is a major stumbling block as your 1MWh TeslaWall with room to spare in your garage analogy brilliantly illustrates.
Well, unless your garage is 1.3 acres. 😉
The Tesla-based Hornsdale energy storage in South Australia has a capacity of 194MWh, so even with the denser 3MWh/acre Iron-Air batteries, it's going to need substantially more real estate.
In any case, transmission losses from large remote storage incur losses & the length makes them vulnerable to damage/failure.
I'd be very interested to know the capacity of the washing machine-sized modules & how many would be needed for domestic storage.
The price might be right, but I fear that they may be too bulky, as the popularity of high-density living will be problematic for strong Iron-Air storage uptake.
Perhaps install the modules underground before pouring a concrete driveway? 💡

Liked and new subscriber!
Eventually, there will be no carbon footprint!
As long as solar, wind, hydro and geothermal can energy pay for themselves, their buildup to the inverse of their capacity factors and their energy storage. Granted, they can work together, especially with longer powerlines, reducing the need to build up to their inverse capacity factors, which would give higher overall E-ROI. What would be really cool, though, would be space solar power... and lots of it!
We will be able to, once again, not worry about our energy usage.

Your air conditioner is a heat pump? Spoken like someone who lives in California and assumes almost everyone, almost everywhere, has an air conditioner, I guess? I live somewhere with a mild climate year round (typically mildly warm in the summers, typically mildly cool in the winters), and I know lots of people with heat pumps. But they all got them to replace their heating systems (usually oil furnaces, very few people use natural gas for.... well, for much of anything around these parts). They consider the cooling as a bonus, as most of them didn't have any kind of cool air conditioning before replacing their heating system with a heat pump. The life assumptions of your Californian perspective showed through in several comments in your video. Not a criticism, just a caution/opportunity to genericize your videos a little to a wider audience. :)
I am excited for this video series, as I know tonnes of people with heat pump systems for centralized heating, but I know no one with any heat pump appliances yet (but I've been looking at them with curiosity/interest!).

In December last year I tried to buy Bolt in Canada and didn't due to very long delivery time. Now I am glad I didn't. I ended up leasing Corolla for 2 years. I still beleive that Bolt would be a good choice from many aspects. It has many good things going on. Electric performance, equipment, built quality, availability, service and other details. However I can't get over design, doesn't matter how hard I try. Also seats are quite bad. Too thin, too small with plastic frame that cuts into the sides.
Why electric car must look like small, dinky, somewhat futuristic vehicle? Yes why? Also I am afraid of small cars because I consider them unsafe. Any crash or collision with regular sized car must produce wrecked small car due to shear lack of size and metal construction. For that reason I wouldn't use Smart car under any circumstances.
Back to design. Why manufacturer can't take let's say BMW 325 vehicle and convert it into full electric car? GM for that matter has a "regular" looking cars that could be a huge success given conversion to full Bolt technology platform. But no. They had to take side road and created unlikable car. GM makes cars long enough to understand that person will not buy a car that he/she hates when approaching every day to go somewhere. BMW had to make i3 with similar results. Not selling at all. Not based on being a bad car but based on freaky design that nobody likes.
While writing this in YouTube there are several other videos suggested on the right side. Some of the cars are even worse than Bolt. One I see is actually in a tricycle shape with 2 wheels up front and single in the back. Needless to say I wouldn't get caught dead in something like that! Technology may be a top notch but design is total failure! Price point is totally irrelevant.
For those reasons when you see both cars side by side, like in this video, Tesla 3 and Bolt there is no contest what buyer will get. Tesla wins hands down every time. For approximately same money why would I buy an ugly car? Something that I have to force myself to like and use? Why they didn't simply take Cruz which will not win beauty contests but is decent looking car and loaded it with Bolt technology?
I hope Tesla will improve build quality and delivery times by the time when I am ready for the next car. It will be a model 3 for me.

Brilliant Work Ricky!
Thanks for the great video! Wow, I'm geeking out over the outstanding job you have done!
I am in the US as well, in the Virginia area (snow today, haha), not your beautiful California. It looks like your home is new, so did you build from the start with solar and make optimizations?
Since winter production takes such a drop-off, I was wondering if:
-- you oriented your home and roof angle to optimize the winter production...
-- perhaps a steeper roof pitch and maybe rotated the home 5 or 10 degrees off perfect south-facing to better catch the winter sun setting further northward?
-- I love all the real data for the solar panel production on each day... It looked like you had some kind of app in the video (about 12:01mins)?
-- Ricky, you said you no longer needed UPS for your computers and electronics... so is the Tesla PowerWall truly instantaneous? We lose power all the time here in rural VA but it takes my propane generator about 15 seconds it to kick in, so I still need UPS's on all my electronics.
Since I am looking at building a retirement home and have never had solar panels, I am wondered what kind of production could be expected... or who is the Authority on the subject. I suspect the payback in VA is much less than San Diego. haha, I'm geek out a bit on planning. I am free to design my roof any way I want and can also orient my home any way as well.
Cheers,
Eric

I just demolished and filled in my pool as the first step of my current remodel.
The 17K-gallon kidney-shaped pool was too small for serious swimming, and too large to use as a hot tub. Over the decades I had replaced the pump and filter, with the filter being grossly oversized to reduce backpressure and thus allow a smaller pump to do the job. A fiberglass liner was added to slash chemical use (by 90%!), later shifting over to a "salt pool" with an electrolyzer. When the liner was being installed, I also replace the pool lights with color changing LED units, which was another energy gain, plus fun for parties. Also tried multiple cover systems, from bubble wrap to a trampoline, each of which had major tradeoffs.
Despite all the time and money invested, I wasn't ever satisfied with the results. Plus, due to a hill in my back yard (starting to drop away just 10' from the back door), my pool was in the front! It essentially consumed 80% of the available yard, largely preventing many other yard uses. One reason for my remodel is to make my home and property pet-friendly, and I'll want my future dog to have a great yard. (I'll get a kiddie pool, if needed.)
The inexpensive bubble-wrap cover did a fantastic job of heating the pool, but aged quickly and was a hassle to take on and off. The trampoline cover was safest by far, but was even more of a hassle to take on and off. A simple tarp cover on a wide spool was the compromise that worked best overall. Best moves overall were the fiberglass liner, salt system and big filter / small pump.
Plus, I live in San Diego! It takes me 20 minutes to get from my front door to feet wet in the ocean. Way, WAY better than any pool, and is one of the main reasons none of my pool solutions ever seemed worth it to me. YMMV, for sure.

I’ve said this before, but they could hire, or buy the tunnel mining equipment from Elon Musk, to place a series of tunnels across the US, to pipe it to areas that are in a constant drought, … create, and build water treatment facilities to re-facilitate, a disbursement of flood waters, from storms and snow melt, flooding , … in order to refill, and replenish the needs of the regions that the pipelines will establish, and reestablish, in areas affected by drought, … storage of water, ie: freshwater supplies that can be found, and done in underground reservoirs, …
And to utilize aqua farming techniques to allow siphon transference of waters across the country, instead of having to rely on electrical pump stations to move the waters more effectively, … and having the creation of moving mass amounts of water over weeks, we could effectively move the same amount in a matter of days, … theses underground pipelines would have to route around any natural, disorders in the continental plates like by passing Yellowstone, as we will have to mine tunnels at least with a 6 foot, compliance shaft, and with effective ballast plates, & panels to adjust the flow rates in order to achieve a longevity to the wall structures of the pipelines, as with any type of material, being pumped through a line, the integrity of wall materials will be under the stresses of some forms of pressures, and the movement of any materials through such conveyances will have an imposed limit of the co-efficient, of friction, … as travel through such materials will congregate forces of water, versus unknown, wall materials, … so to achieve a maximum volume, a standardizing of wall materials will need testing, & maintenance, even if it is only being monitored by relay sensors, … with a visual inspection in order to maintain, a constant flow projection, and if manned, visual inspections are required, then lock out procedures must be followed thusly, as to avert any type frame, &/or form of catastrophe, … and waters from the source shall be required to be channeled to different areas/regions, with the beginning of a lock out situation, … prior to entry by manned inspectors, …

Bro they are building for super rich 🤑,after climate change disaster,world economy is going to collapse,eg the movie,hunger games, maze runner,the last of us,etc
Climate change disaster is increasing day by day ,soon we could have food shortages,flood , drought,
Connect the dots🤔😁

Vehicle balance is a matter of design intent and preference. Taking Rear Midship Rear (RMR) drive cars for example, the bulk of the operating mass is toward the rear to make the front of the vehicle much more responsive for maneuvers. We will see a LOT of this comparison when the RMR Corvette comes out and is compared to the C7 Corvette, which has its engine in the Front Midship (FM or FMR) position, to that end.
Having an evenly spread out weight distribution reads as advantageous and in most vehicles, seeking stability, it is. The Vehicle is much less apt to twitch change direction with a perfectly distributed weight. So any such car is not going to be the best at cutting corners. Even Front or Front midship cars have the ability to use their often somewhat lighter rear ends to induce over steer that makes harder maneuvers ever. I say "often" as the Dodge Viper, for example, was actually "tail heavy" its balance was more like RMR sports car. In fact, most sports and GT cars today, while more closely 50/50 balanced are still either lighter to the front or the rear allowing more dynamic driving techniques and strategies to be used... just not to teh same weaponized degree and more deliberately unbalanced cars like the Porsche 911, Ferraris 488, among others.
The Lower Center of Gravity (CoG) is always desired, but in practice there is such a thing as too low, as it makes it harder for the vehicle to "dig" into a corner to better use its tires for grip and handling.
Finally, a higher curb weight is NEVER better. More weight stressed suspension and chassis parts. It taxes the tires and brakes more. It also demands MROE weight to support more weight. But on the up side, a heavier vehicle is somewhat easier to setup of a more comfortable ride, and you have more weight on the tires top facilitate more grip from a standing start, great for drag racing.
Future Sports cars will be very reluctant to use large amounts of batteries if they can actually avoid it simply because of the weight. If anything we may see more cars like the Koenigsegg Regera, which has one of the most evenly blended and stunning effective Hybrid drive systems currently in existence on this planet.

Great video. I'd never thought you'd ever cover anything I'm actually familiar with.
My two cents on it. You state It's a gothic construction. It's not. By no means. This is modernisme 101. (You may want to deep dive in the trend, I personally find it fascinating).
I remember visiting la sagrada familia familia when I was a kid, back in the late eighties. It only had the towers, nothing in the middle. They had no clue how to continue as the blueprints had been lost (as you very well stated). The "plan" back then was to make something sort of "plain", Notre Dame height style, just rectangular.
Since then, the speed of construction skyrocketed. That's because it was open to visit for tourists (they said 'the japanese love it!' back in the day). The tourism money made all the difference.
Later on, to decide on the center construction, they thought that Gaudí's late 'capella de la colònia Güell ' was a training exercise for the sagrada familia. So they decided to go for that design, adjusting for size and grandeur.
On Gaudí's death. It is said that he was a very stubborn man and he thought that the streets were for the pedestrians. He strode every day, doing the very same path. Ignoring all traffic until some day he was just ran over.
He also used to say regarding sagrada familia 's delays: "el meu client no té cap pressa". (My customer god is by no means in a hurry).

Some advice for you on the salt cell, you’ll get a more life out of it if you chose to clean it with a less aggressive acid to water ration and spray it out with water. As soon as the calcium carbonate is loosen from the acid mix is a good time to start rinsing it off just be care at first for the spray back.
The percentage of output doesn’t mean it’s making more chlorine, it just means it running more.
An example we always give is at 100% output, your cell is running 60 seconds of every minute and at 50% output it’s running 30 seconds of every minute. Every manufacturer has their own timers, but that’s the principle it works on.
Also, I’m not sure at what stage of this that you’re in but if the deck is still pulled up, you have a Really Great Opportunity to increase the size of your plumbing. There’s math involved in determining what size you’ll need (I’m by no means an expert on it but we are a repair contractor in Florida that does work just like this).
Anyways, when you increase the size of the plumbing, you decrease the resistance which means you’ll increase your flow rate at roughly the same amount electrical cost.
It’s something called Total Dynamic Head, or the friction of your entire pool to include from your pool to your equipment pad and back again.

Steve Barnes is the expert there, guy’s a genius!
Thanks for doing what you do, we love watching your videos!

Hey brother! I'm also in San Diego. I would love to meet up with you. Anyhow, there is one thing I haven't heard you talk about in this video. The more water you suck out of the air, the less moisture will travel inland, thus increasing water scarcity(a.k.a. less rain) in many regions, including many mountain ranges that get snowpack and feed into our nation's rivers. Even if we do this out in the oceans far away from shore, it will still reduce the overall humidity of the Earth, thus leading to increased desertification. Saying all that though, I am looking into these technologies to help my family in the near future. To anyone paying attention, California is already strarting to run out of water, as are many other regions. Mexico is having many cities in crisis right now, like Monterey. The only sustainable solution for the world is desalinization, or if we are going to pull water from air then we first need to add extra moisture into the air through boiling ocean water.

Great and accurate presentation. In Northern California, I added to solar panels a 20 KW whole house generator (8K total including installation) including automatic switch instead of batteries. PGE offers rebate after 9 months, maybe, on batteries for what would have been 21K outlay for 2 batteries and extensive rewiring to accomplish a critical load setup. Only caveat is that you don't want the generator power to restart the inverter when the grid goes down. I accomplished this by isolation of the generator system from the solar system by putting in a subpanel so that there is no crossover. Interestingly, the installer was unaware of this issue, but honored their original bid. I am told that Generac was talking about an add on to their generator setup to accomplish the same thing. Get the EV first, if you have enough roof space, as that would figure into how many panels you are allowed (at least in California). Loving every minute, including the Tesla Y. There are still $10,000 rebates and credits on Volvo XC40 EV and other brands, so that the difference in price is recovered in 3 years.

Both of you individually, and now together, might be the two most likeable presenters on youtube - reasonable, intelligent, engaging, informative, but beyond so many others, you are simply pleasant, respectful people...So rare to not find someone being annoying, annoyed, or simply not funny. You are just real, in addition to professional. Thank you!

This whole balloon fiasco makes no sense. US, under the Project Genetrix, flew more than 500 high-altitude balloons over China and Russia territories, and around the world. US insists that it is within its international rights to do so. National air space is usually around 30K feet above ground. And these high-altitude balloons fly 60K feet above. Granted, they are flying way lower than the low orbit satellites and the international laws are vague about this. But the real point here is that US is, in practice and in statement, accepts this as concensus.
In fact, China and Russia routinely fly these high-altitude balloons over US territories. During Trump administration, China flew 3 balloons over to US. And US military, politicians and media did not raise any concern. After all, US is doing exactly the same to the world. So this sudden rise of "outrage" by American media is puzzling. Is US turning back against its own practice? Or is it that US government wants to create tension between US public and China, so to distract its people from social unjust and economic stagnation at home? Or worse yet, is US Military Complex trying to create tension with "scary foreign enemy" to extract more money from its own country?

Congratulations times 10! Delayed gratification at this level is beyond words or comprehension. Timing is everything. The impact on you, the people you work with, and the people that know what you do for a living, are about to see a transformation the day you pick up and drive for the first something that has now become a part of you. From now on it will all be through your eyes and ears, not something you read about something you heard about and I believe you will no longer have to go to the source, because from here on out you are the source. I've been watching you guys for a while you guys been doing some really good work but this is going to be a big change, a really big change. Here's just a bit, something to think about. Set aside piece of paper and a pencil and over the next 7 to 10 days write down everything that comes to mind everything that is good about Tesla. And at the same time whatever comes to mind, whatever you or whoever thinks or feels something bad about Tesla. Write that down too. And know that in time, all the things bad, that people have the said and thought will slowly disappear and will be forgotten and what will remain? Is Tesla. That is who they are! And once again congratulations times ten and enjoy the ride! You've earned it and well deserve it!

A few points.
Two things to note regarding the Porsche battery.
The large buffer is due to the smaller number of cells.
If, as seems to be the case with the pouch format, the cells aren't as resilient as the Tesla cylindrical cells, they will need a certain number as backup in case of failure(?)
I believe that the pack contains approximately 400 pouch cells, meaning a single reserve cell is 0.25% of the pack.
The pack is reduced by a greater percentage both by the buffer, and if cells fail, than a Tesla pack with (at least) 4000 cells? 10 cells for the same effect.
Also, with more cells, the stress is more dispersed.
Gearbox.
As we know, the advantage of EV's is instant, maximum torque from zero motor speed.
Their failing is a drop in torque at higher revs, and since the drive is essentially fixed, high wheel/ road speed.
I suspect Porsche worked out that there was more to be gained by gearing the rear motor for higher torque at launch, then as it's revs reach the ideal peak, using a high gear to drop the motor back to its high torque band and freewheeling the front motor when cruising.
Side note.
When Tesla tried gearboxes, they blew them up.
That was then, this is now(!)
They have the development resources and time available (!)
Gearbox in the "Plaid", roadster?
Could be a component towards the range?

Rick E. Dat was another good one! Great factual info, yet independent. One might think you work for Tesla? Ha ha. Another might think you did your homework? And your focus and firm beliefs in Tesla, seperates the narrative from an opinion. You go to the source and drink from the well, as others drink from a bottle of water. It's just water or is it? You, know the difference between the two and they don't. Maybe one day they'll drink from the well and as I watch more episodes of you and maybe it dozen others who like you are original, focused on the facts and believe. It's what I call "a conceptual formula". And that came about after months and months of watching Elon time after time coming up with a concept, and then surrounding himself with great a bunch of brainiac people who believe and come up with a formula that works. and I can't wait and I look forward to the day that is hanging out and playing with his five boys and slowly starts to conceptualize the education system in this country and starts looking for a formula that works. and in the meantime you just keep doing what you're doing because you ain't got much of a choice haha! and I'm holding you to this what you decide to post it or not, when you show up to pick up your car, there are two people with you with cell phone cameras that record you walking up, climbing in, firing that thing up, looking out that windshield to a great future!!!!!!!!

The problem with the statement was it implied, strongly, that future production of gas stoves should be banned. Many homes that use gas stoves also use gas heat. And as you said, gas is way cheaper. So $100 extra for cooking may not be much, but a doubling of a heating bill may be death to a lot of people. for heating. And the language used in the statement just seemed to be that same type to be what some may describe as 'woke', but also government speak for we're doing it for your own good. ie the incandescent light bulb debacle. (Though yes, I am also all LED now, but the CFL in between was horrible).
Personally, I am building an off-grid home, and will be using induction mainly because I don't want to go through the hassle of running a gas line inside the house. The house will have an ACH50 rating of about 0.5, which is nearly sealed. I will have some gas, for an outdoor fire pit, grill, patio heater, and pool/spa heater. But all those lines are outside the house.
And let's not forget induction ranges are at least double the cost of gas ranges. On top of new pots and pans.

ICE Vehicles grills are more an affectation of styling and shockingly do not need to be so big. This is not merely about trucks, whose grills have mostly become ridiculously, cartoonishly, huge and ornate. To be fair, the new RAM Grill looks great and is not at all overlarge. Probably works great aerodynamically as well.
If you recall, just as an example, early Ford Taurus and Mercury Sable sedans. These did not have very large grills with only moderate sized lower opening, not any larger than what is seen on BEVs now, for cooling. Teh Famous "blocked grill" look. If you look in the engine bay of most modern vehicles, the air intake box is often positioned and opened very close to the front (or outside) of the car. This is so it can get the most outside air and be free of ambient engine temperatures inside the engine bay. As a result, most of the grill is NOT needed for engine air or cooling. The lower intake often seen on most vehicles now is more than enough and a small grate or slot is more than enough for engine air intake.
Tesla's lack of a grill looks awful because it looks like someone forgot to remove the protective cover. It looks bad, generic as a white can with only the word "beer" on it and is easily to most unattractive part of a Tesla's exterior.
Next, Drag is misused by seemingly everybody, even trained experts of aerodynamics. Drag is essentially the vacuum force generated by an object exiting a given volume of air or space or air. This is the force of the air trying to get back to where it was or filling in the vacuum space behind the object. This force of drag increasing both with speed of the object and the size and shape of the area creating drag.
In regards to the Grill, you are thinking of Wind Resistance (WR), a somewhat figurative name that describes how much the air or wind, felt as movement through air, resists being moved out of the way and/or increases the difficulty of and object to move into or through a given volume or space of air. Grills create a good amount of WR. However most grills, even huge ornate ones, often produce far less WR than their visible area entails. This especially as most grills have slats and grating that block and deflect so much incoming air as to reduce the effective area. Modern aerodynamic theory and practice actually has the fairly frequent habit of rendering huge, gaping, "fish mouth", grills as near zero impact on the vehicles aerodynamics at speeds the vehicle would not try to take flight at.
Grills are largely retained because unless you just like having utterly generic looking vehicles (looks at Tesla), then grills are not going completely away, if at all. "When all vehicles have the same features and capabilities, the remaining defining attribute is design." - Peter Delorenzo (Paraphrase). Yes, people are still attached to them, the car makers and the people who buy them. They are needed for various functions, but do not need to be so big. But in the end People want their car to look like something, not like nothing. Tesla gets away with it best they are the only ones doing it. Leave the to it. To Everyone else, find their own solution.
It is never simple or easy, it only looks like it because it has been so developed over so long a time, it is taken for granted.

OK I'm a little confused on the comparison at time index 3:00. Why compare an Electric Tesla Sudan with one of the worst gas guzzling vehicles that probably only gets about 20 mpg and weights far more than the Tesla. You should be comparing it with a Tesla Truck no the Sedan. The two vehicles shown have totally different purposes, a Sport Utility doesn't have to same role as a Sedan nor it intended to. If you're going to compare two vehicles at least rate it by vehicle interior space, passengers and cargo carrying capacity in weight. per MPG. Why not compare it with a Toyota Yaris that gets 42 mpg and has about the same interior space as the Tesla? Don't forget Hybrids too, they charge while you drive and don't take 40 minutes to fuel at the 300 mile stop. It seems you're comparison is comparing the best with the worst. Also how about figuring how much Fossil Fuel it takes to generate the electricity to charge that Tesla into the MPG as well? After all that electricity didn't just appear out of thin air, even if it was Solar, that currently only makes up a very small percentage of electricity put on the grid. Now I'm all for EV's but if we're going to do some comparisons let's not compare a Diesel Locomotives MPG to a Toyota Yaris to prove our point. Comparison should be based on similar models, purpose, range, weight and occupancy per mpg, including the Fossil Fuel MPG figured into the Kilowatt used to charge an EV at home for the average person's ability to charge one. Good video though and I enjoyed it. I look fwd to the day we can fuel them at the same cost per mpg and time as a gasoline vehicle. Currently as a WHOLE the electric vehicle is nothing more than a novelty in it's ability for everyone to have one and be charged by the current electric grid. Simply meaning if everyone had one and charged them based on what economically available to the public, we simply couldn't afford it nor would the Electrical Grid be able handle it right now. Best Wishes & Blessings. Keith Noneya

Cool Video Ricky!
I work in the airline industry, and we are right in the middle of replacing our handheld Halon 1211 fire extinguishers for what is branded as HALOTRON fire extinguishers, which is a non Ozone depleting alternate fire extinguishing agent. The chemical formula is 2,2-Dichloro-1,1,1-trifluoroethane mixed with Tetrafluoromethane... Whatever that is LOL! According the Montreal Protocol, which was adopted by the ICAO unchanged, we will have to replace all handheld Halon 1211 fire extinguishers before the end of 2024. 3 extinguishers per Boeing 737, that are a lot of extinguishers to replace! But imagine the worldwide fleet of commercial aircraft, that are tens of thousands of extinguishers that need to be replaced the coming 2 years.
We already have replaced all tiny fire extinguishers in the lavatories, these are to supress a fire in the waaste receptacle.
For the fixed fire extinguishers in the engines and cargo holds we still have some time to replace them, in new aircraft they are already banned.
Btw, did you know that Halon 1211 and Halon 1311 are already forbidden to produce for decades? Since 1995 or so Halon is no longer produced and all Halon in scrapped extinguishers is recovered and hold in Halon Banks at many places around the world so it can be reused in new produced extinguishers.. At some point these Halon Banks will start to destruct this halon into other chemicals, used in the chemical industry.
The Airline industry has had an exception of using Halon, because there were no alternates that worked as good as Halon. but the coming years this will also come to an end and good enough alternate fire extinguishing agents have been developped.

There are 264 gallons in a m3 ... well a 400 gallon a day leak like you had in Belgium where I live would be at the minimum €7.27 per day, or $8.00 a day, over a period of a year it would be $2,920, but it would be WAY worse. that base rate of €4.5163 euros per m3, is the base rate up to 150m3 for a family of 4, so you would pay the much higher excess water rate, which is double, so you are paying $16 a day in reality, or $5,840 a year for that simple leak. Man US water rates are so cheap. FYI, our guest house, which has a family and up to 12 people at some points living here, uses in the 350m3 range on the high end, closer to 280m3 in normal years, your leak was 553m3 of water in a year!

Dude, love your videos. You asked for suggestions? OK. As to economics and engineering of cars, electronics and the HD DVD vs Blue-Ray format war. You're comparing Apples and Rubik's cubes, let alone two fruits that at least both grown on a tree.
FYI. I drive a 14 year old 4.3l V-6 full size pickup. Ford C-Max Energi went away after lease. Why don't I drive a new more efficient vehicle? Too expensive. Laying off the regulations eases pricing pressures putting newer, more efficient vehicles in reach. Would I Love and prefer and electric pickup? Yes. Is that what I'm going to get next? Nope. Been waiting, but the required factors have not come into place nor will they for 10, more broadly, 20 years. Regular improvements over time is always the best case. Next a 2.3L Ford Ranger. Nearly halved my displacement and 40% better fuel efficiency still does the same job as the full size rig. Since I'm retired due to a... er uh uhmmm a car crash... I"m thinking a 2nd hand Nissan Leaf for my run around. Basically what the POC Zap car/truck I bought in 2007 was hoping to be.
The ICE is dying out all on it's own via consumer choice: The ultimate arbiter of everything that succeeds in the consumer market. Big leaps forward don't happen overnight.... At least not until: 1. Prices come down to mainstream affordability. 2.Models gain broad mainstream market acceptance 3. Infrastructure is fully built out. This is from a guy who bought a SLA battery powered ZapTruck in Portland OR in 2007. Biggest pieces of crap ever, but consumer demand was there.
I might humbly suggest doing a lot more research into automotive, economics, electronics and history before making such broad statements. Nothing any POTUS does is going to help or hurt Ford, GM, Tesla or anything else in the end. Never has nor will. ONLY the consuming public decides with their wallets.
EDIT: PS. Read Tim Ferris's books. Solid dude. I suggest Freakanomics I & II by Levitt & Dubner. Two favorite geopolitical analysts: Check out Peter Zeihan (righty) and Mark Blyth( lefty) Those two guys lectures say it all. Go back a decade or so. See what they were saying. Cheers.

Perfect timing for me, I have never heard of Earthships being described as Net Zero houses before. I have always thought of it as a desert based architectural style.
Why are you growing grass & cutting it short. As a demonstration tool that you can "tech" your way to a classic green lawn in the middle of the desert it has a value, but as a use of space & resources its barking. A far better choice would be to look at the work of Geoff Lawton either with his work in Jordan or at his home farm in Australia where you can learn about the creation of food forests so that you may never have to buy food again, as a constant stream of food is available to both your family but also to your animals that can in turn contribute to your freezers.
If you want grass, switching the grass your using to a deep rooting, high growing nitrogen fixing grass would be a good start, preferably one that has San Diego local wild seed spread amongst it. You ideally want to be growing as diverse a set of wilderness seeds you can, so your lawn can adapt to whatever the local conditions in that few square foot/inches see. There are grasses that are good at punching down through layers of clay creating deep tap routes up to 10 feet long, this means they can also grow upto 5 - 10 feet tall i.e perfect for cutting & dropping, which then will rot into deeper/thicker soil. Even better would be to keep chickens or if you have the space - pigs that you can feed on your kitchen waste. Chickens & pigs are great at completing the symbiosis with grass that forms the basis of carbon filled soil manufacture. Why do you want carbon heavy soil? Because the more carbon that is captured the closer to peat it becomes & what's as so good about peat - its constantly wet year round due to the amount of rain water it captures.
And if your land is constantly wet even in summer, your garden remains cool & pleasent year round. This results in reducing the energy bills both in the summer & in the winter. Why? Because water retains heat in the winter (water stores heat much better than dry soil) but in high heat evaporates off cooling the land. This then creates an environment around your house that leads to lower use of your whole house heat exchanger that gives you heating in winter & air conditioning in the summer.
If your looking at rebuilding your home you really want to be talking to Matt Risingher & his YouTube channel & external Build show website. Matt whilst based in Austin Texas goes all over the country, he is generally focused on the building Trade & knows a lot about Building Science, such as perfect Wall & achieving almost total control of emissions into & out of a house, whilst using air & heat exchangers so your house is constantly filled with fresh air at the perfect temperature 24/365.
If you want further recommendations do ask, their is an immense amount of YouTube resources & Creators available. We as a planet have the ability right now to stop & reverse climate change to where we were before the start of the agricultural revolution in less than 30 years. We already know enough that in 30 years time we might be opening up coal based power stations due to a lack of carbon dioxide in the atmosphere!!
Looking forward to learning & sharing with you over the years to come, will Matt be joining you for a Boston perspective?

Love what you observed: "Japanese turn everything into an art." So true! So wonderful!
Re the USA, I notice that tourists who visit Disneyworld Resorts in Florida are fully safe staying in their Disney hotel rooms during a hurricane. Meanwhile ordinary Florida homes are torn down by the hurricane winds. Which points to the fact that hurricane proof houses should be the building regulation norm in Florida, and also points to the fact that ordinary homes are far too weakly constructed. While the Japanese constantly improve their home construction standards. How wise the wonderful artistic Japanese, and how brilliant and wonderful Disney is! Just many building laws in the West - Europe and America - need to catch up.
My house here in England was built with about a million other very similar homes by the British state between approximately the 1930s and the 1950s, and this one in particular should have had ten foot of hardcore compacted above ground level to avoid this house, and thousands of similar homes, having damp floors and walls downstairs. Pretty well my whole street has had collapsing downstairs floors due to the homes having been built too near the clay of the foundational alluvial plane here. And in modern times, have we learnt? Of course not! We continue to build tens of thousands of homes on land that can flood, land that should be raised above the highest flood level with modern earth moving machinery. Simple.
Thus, another factor of Japan's awe inspiring and beautiful approach to home construction and building laws is that of Japanese pragmatism. For example, if the Japanese ran Florida they would make sure that all the buildings were as safe as the wonderful Disney hotels are in a hurricane. And, if the Japanese ran the UK they would make sure that new buildings were built on ground that had been raised above the potential flood level. Too beautifully simple for us to imagine. So obvious for the artistic pragmatism of Japanese vision.
