Hearted Youtube comments on Two Bit da Vinci (@TwoBitDaVinci) channel.

  1. Thanks for all the info you provide on your videos, I enjoy them all. it’s refreshing listening to smart individuals like yourself. We need more people like you instead of the tiktokers dancing and and lip synching that we currently have in this era. Keep up the good work and research.

  3. I get it. In the low range days of 75 to 85 miles, people would go to extremes in order to keep warm; blankets and boots were the norm. And thank you for all your hard work. I've owned five EVs since 2013, and around ten fossil cars. My Model 3 is by far the best car I've ever owned.

  4. Anectdotal: We live just north of Boston and shut off our gas line. It saved us in $250 per year in flat fees. We use a German heat pump, induction stove (love it) and heat pump water tank (enabled us to remove our chimney). Winters get very cold and the heat pump can do it but our house is not well designed to keep heat in (old insulation and too many windows etc). So we have a pellet stove that serves as our supplementary heating. It is affordable and I enjoy looking at the fire. Pellet production is iffy too so needs some work. Hoenstly one of the biggest energy issues is not source but home design. Too much sunlight coming in in the Summer; too many windows in the winter etc. I envy those efficient bermed (sp?) nestled into a hill.

  6. As an engineer, I have felt that full FSD is further into the future than many imagine. Thanks for your insights that suggest this is the case.

  7. Kudos to you for going for Used panels. I have often seen in people that in their quest to greenify things, they often forget the "Reuse, Reduce, Recycle" part and actually end up buying a lots of stuff....which is nothing but consumerism and the worse part - it feels guilt free. Thank you for bringing a frugal and hence more sustainable approach in highlight.

  8. One Pro Tipp for the window heat film: If you install it on the ouside + not directly on the glass then it has the highest cooling effect. The heat film gets hot but does not heat up the glass behind because there is no direct contact so less heat gets into the house. It acts then as a transparent heat shadow for the window. Only disadvantage is the slight noise it makes when the wind blows around it but this might be avoided by spanning the heat film on a wooden frame. That way it could be easily mounted in the summer time and taken off in winter time too. Other than that, cool projects you have shown there that can save a lot of energy and money. Especially in an arid region an evaporation based cooling might also help to keep the humidity in a level that is good for humans (50-60%) and reduces costs on cooling. I would just use an indoor one so that water will not evaporate to the outside if the device is not on.

  12. As I am taking a break from my LEED GA CE course, and worrying about water shortages, getting to net zero energy, and carbon emissions, I watched your video and could not believe the content. It could be the possible answer to these grave issues. Thank you so much for sharing your knowledge. I always enjoy your videos.

  13. Informative, your presentation was clear and concise, giving the common YouTuber much needed fact based insights into the technologies used by the industry players of this complex world changing technology. You have helped separate the hype from reality for me (Common YouTuber), I have learned more from your short presentation than from all other sources combined, well done and well appreciated.

  16. For your title alone you deserve more respect and likes. A stark contrast to the pathetic titles I'm seeing about Battery Day from YouTubers. Great job and breakdown.

  17. Ricky, an absolutely excellent explanation! I couldn’t agree with you more, regarding what an important tipping point this is for EV adoption and, as you pointed out, for the selling features of different car manufacturers. It doesn’t matter how good your vehicle is, without a NACS (Tesla) charging compatibility, it won’t sell.

  18. Using the gravitational equation, even at where the ISI is, you only lose about 12% of gravity. You go up to get out of the atmosphere, you go sideways, very fast, to get into orbit.

  19. It’s simple… I am not a truck person, nor have I ever been, BUT, I want one of Ford’s F150 Lightning EV Trucks and can’t wait until they are available.

  20. simple solution: Make the big data companies pay for the construction of nuclear power plants, to even out the energy it progressively takes out the regular grid from people. Clearly they got the money for it

  21. Man... You California LEFT coast people need to get out a LOT more. I live in Canada. I was born and lived in Labrador. This whole malarkey with plugging in is long gone. I haven't had to plug in my cars since I started owning cars some 25 years ago. Unless you live in Oymyakon in Siberia and it is the dead of winter, "petrol" cars work marvelously in the winter. Where I live, the deep winter night temps REGULARLY go as low as -25 C and many daytimes that are that bad too. Your precious Tesla is NOT going to do well on those days or the ones close to that. My new 2017 Civic has a start button and never ONCE had a hard time starting. Also, those "Canadian" owners? I can assure you they are NOT representative of Canadian winters. Vancouver = Seattle. Toronto = NYC (Due to all the lake water warmth and the sheer sprawl of Toronto). Montreal, maybe something there but nothing compared to the rest of the populated areas. Give me the data for Edmonton or Ft Mac or Winnipeg. I want my car to go a KNOWN distance EVERY day. No guessing based on if it is cold. I have said this once, twice, and many times more... BATTERY cars are NOT the future. Electric cars are. The issue is and has always been storage. The answer is and has always been capacitors. Graphene will allow for the energy densities that existing capacitors can't provide. Capacitors allow for ALL weather condition operation and can be charged or discharged at effectively any rate and won't wear out anywhere close to what happens with a battery. The reason is simple. As long as the storage medium is electrochemical, it is a failure. Electrostatic is the only answer and also THE answer as it will also solve all manner of grid storage and solar storage and discharge issues. Unless solid state batteries can challenge capacitors, I stand by my statement until something better than either is invented.

  22. I’m proud we are actively taking step in Quebec towards environmental protection

  23. The people making and using and selling the plastic should have to foot the bill for the recycling that only makes sense

  24. Hydrogen is the fuel type of choice... for the OIL industry. 90% of hydrogen is just another form of fossil fuel. They will still need to stop at gas stations, and would be far better for oil companies. As for the consumer, EVs are easier, safer, simpler and better performing. It’s obvious who’s winning this race!

  26. At timestamp 5:29 you are showing price for Li and you have the pound price confused with the kg price, it is reverse ! 1 kg = 1000g vs 1 lb = 454g

  27. To borrow the format of the late Steve Jobs: It’s a vehicle. It’s an emergency power supply. It’s an employee. It’s a vehicle. It’s an emergency power supply. It’s an employee. No folks, this is not three different products, it’s a Tesla.

  28. I've been waiting for a video like this where someone talks to us like an adult. I love my Tesla and I have no regrets about buying FSD (at $5k) even if it doesn't get better than it is now, but I agree about the front camera coverage/angle and resolution. And I agree about the necessity of redundancy, whether it is cheap lidar, better radar, or whatever. And thanks for bringing up MobileEye, it gets ignored a lot. And thanks for keeping it real!

  29. Little side note, when a flywheel is used to adjust the angle of a space craft by either adding energy, or taking it away, they're referred to as reaction wheel, usually having 3 of these wheels on 3 different axis

  30. I’ve long wondered why Tesla YouTubers don’t cover SpaceX and vice versa, Please do more. Boring company and Neuralink too.

  31. 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.

  32. Great analogy between cars and planes!
    36
  33. All of this is such good info and even after my hundreds of hours of research I learned a few things! Very cool!

  35. It's a strange design from an urban planning point of view. I remember from my studies in architecture that the one thing you don't want in city design is a linear city as travel distances become really big really quick. One of the main examples of a modern, functional city we learned about was the Ville Radieuse by Le Corbusier with its separate residential and commercial zones connected via underground transit and its vertical villages. As part of our studies we did a semester looking into the vertical city by designing a vertical city of 1 km high, which posed several challenges like (obviously) the structure needed to support such a city but also how to design the vertical infrastructure. Another challenge was how to deal with all the installations like heating, cooling, ventilation, water supply and waste water. I wonder how they plan on dealing with things like that in the Line City.

  36. How about colour changing paint, that changes based on "Temperature". White during the hot sunny day and black during the cold or cooler evening.

  37. I've always wondered if you could just spread the brine out enough to not be a problem. If you fan out the outlet pipes into the sea far enough and have small holes along the way, the salt should just mix back into the water, right? There has to be some acceptable level of variation in water salinity that wouldn't kill everything. But hey, if you can extract useful resources from it, that works too. Pull thorium out of the water and run a MSR reactor to power the whole operation.

  39. Love this car! The test drive looked like the ride was very bumpy. Of course that could simply be that the roads there are very rough. I hope they get this thing on the production line soon.

  43. Great video, the EV1 was such an interesting case study in crony capitalism, but also a product that was well ahead of it's time.

  44. I grew up in sf in the 70s and 80s riding our electric gyro busses. Dad explained the tech but I had never seen it until now!

  45. Battery day is going to be exciting. I’m thinking a large jump in range which should compete with or surpass the latest announcement by Lucid. Btw, CyberTruck is going to be a beast. Glad your wife gave the green light. 🤙🏻

  46. This video was super informative! Thanks so much for making it!

  47. Your best one yet, thank you for the overview.

  48. Right on, Ricky! The only thing I would add, is that aside from their monopolistic practices, ownership of the grid, and ownership of CPUC, SDGE is most definitely not a monopoly in terms of supplying energy to us here in Southern California. San Diego Community Power supplies RE to 800,000 account holders in SD County. Please take note of us and this. Maybe even consider doing a video about us. We are a big deal. Second biggest CCA in California. Let’s talk about it.

  49. Heating your house to 76ºF and you are still wearing a jacket? I cracked up laughing at you when you tripped on the corner of the rug and your popcorn went flying! I am so sorry, but you did a fantastic dramatic opening scene to this video.
    34
  50. Hey Ricky, great video as always! I gotta disagree with you on one point. Standardized chargeport locations aren’t what’s needed. What needs to happen is a change in station design to allow pull-thru vehicles so hitch racks and trailers can easily charge.
