Hearted Youtube comments on Ziroth (@ZirothTech) channel.

  1. This propeller design originates in Tasmania in 1971. It was developed by D B Sugden, an engineer consulting to The Robbins Company (a US company out of Seattle, specialists in hard rock tunnelling machines). The Robbins Company financed an R and D project lasting 2 years in collaboration with David Sugden. I joined the company in that year, thus I speak with some authority. We built and trialled a series of propellers from about 10 inch to 30 inches swept diameter. At that time the difficulty was reproduction of form, a problem which, as you point out, is overcome by CNC capabilities and 3D printing. Trials and wind tunnel testing demonstrated significant performance gains. I recall that a large prop was provided to a fishing vessel owner on the understanding he would trial it for a few months. He refused to give it up because it was so good when the trial concluded. The manufacturing difficulties of that time precluded further development.

  3. As a former submarine sonar tech you have no idea how terrified of cavitation I am 😂

  4. I had always understood that this was not a "problem". It was known perfectly well that fusion power would not be usable, unless we had fusion reactors that could use only deuterium as fuel. Current attempts at making fusion reactors with deuterium and tritium as fuel are only intended as a steppingstone on the way to building a fusion reactor that will actually be useful.

  5. I feel the fish will be crushed between the ball and sidewall like a mortar and pestle.

  6. Recently, I had an enlightening experience while using a small electric motor on my boat. I want to share this because it illustrates the significant impact that underwater noises, like those from propellers, can have on marine life. While I was out on the water, something remarkable happened. I switched the motor into reverse, and to my surprise, a seal popped its head up out of the water. Intrigued, I stopped the motor, and the seal submerged. But when I hit reverse again, the seal resurfaced. This wasn't a one-time occurrence. Each time I alternated between forward and reverse, even from a distance, the seal would respond by appearing while the engine was in reverse. This was particularly striking because the motor I was using was very small and relatively quiet – an electric model. Yet, the seal's reaction was immediate and consistent. This interaction, as amazing as it was to witness, really drove home a crucial point for me. It made me realize the profound effect that underwater noise – from things like propellers and even sonar – can have on aquatic creatures. The fact that even a small, 'silent' motor could elicit such a clear response from the seal underscores the sensitivity of marine life to our human-made sounds in their environment. It's an important consideration for all of us who spend time on the water and a reminder of the broader environmental impact of our activities.

  7. Marine Biologist Frank Fish? You cannot make this up!

  8. In Australia we have this energy freely available in a town called Portland which is in Victoria but the authorities closed it down, it supplied thermal energy to the hospital and heated the local swimming pool. Greed at the top end stopped us using it. Power companies must do favours for the rats that are in power.
    792
  9. " ...a team of researchers from Wuhan University..." This is gonna be a hard sell.
    774
  10. As a drone pilot, I love the idea of quieter flight & improved rfficiency! Hope these make it to the marketplace soon! 🙂
    762
  11. Two (semantic-ish) points: It's not exponential if it goes by the square. And saying "temperature is 23 percent lower/higher" is basically absurd as it's scale-variant.
    711
  12. Pro tip: don't put "insane" in your header. In 2024, it means "mediocre clickbait".
    667
  13. "Nuclear Fusion's Biggest Problem" is that' it's not working, so they made it work? No? Title is misleading.
    655
  14. Tritium breediing does not have to rely on the fusion reactors, it can also be done using other neutron sources. It adds to the cost but is feasible. As for the Lithium 6, as soon as te demand is there the facilities will be uilt, just like with any other material. the process of enriching it is well understood and the fact that a site that was poorly run decades ago is no longer operating does not necessarily mean that the method itself is unsuitable. Other than that a good video.
    608
  15. Technically, no one can say that this technology isn’t revolutionary.
    580
  16. Unpopular opinion: Hydrogen powered vehicles are the new fusion reactors of our time. They will always be 20 years away from full adoption.
    576
  17. It was an absolute pleasure speaking with you! Thank you for telling the story of industrial decarbonization via electric thermal energy storage.
    547
  18. It's crazy how much improvement can be made to everything we already have.
    512
  19. The German Engineer joke: "that's all fine and good in practice... but how does it work in theory?!?" 😂😂😂
    510
  20. There is a computer fan maker called Noctua from Austria. They have been well known for making quiet fans. If you go their website you will see the same flutes on their fans. This idea came to them more than 20 years ago, after their R&D labs led them to fine tune their observations.

  21. This would be great for off shore sailboats and motor boats which use "water makers" to produce fresh water. These units are reverse osmosis devices but they use a lot of power which is a problem for boats running on solar.
    472
  22. It would be interesting to see whether a variant of this would be suitable for use in energy production plants, such as wind farms or hydro electric dams
    462
  23. I have pulled my 3 man canoe along with a kite before. Good fun and very fast.

  24. "Dams can cause negative impacts if they break". Bit of an understatement 😆

  25. as someone who has spent most of the last 18 years on oil rigs, as a geologist, and later an engineer, I can say that the process to drill deep geothermal wells is not really any different to conventional oil and gas drilling. We have the technology to drill very deeply already, we don't need this new plasma method that will use an incredible amount of electricity. Just because some technology exists, doesnt mean it's going to be affordable, or applicable. Geodynamics, a company in Australia already built a proof of concept for enhanced geothermal, or hot dry rock geothermal (look for Geodynamics Habanero project). They drilled multiple wells to only 4-5km deep, and circulated water between wells, generating steam, and electricity. One major economic hurdle was affordable corrosion control, not the technology to drill the wells. Conceptually, it's awesome, no need to burn fossil fuels, etc, but the reality is that there is no point building an amazing system if you cannot maintain the equipment and sell the end product at an affordable price.

  26. So exciting! My dad was a metallurgist and cast many large propellers for military, cargo, and passenger vessels. I wish he was still around so I could share this with him. Thank you!
    389
  27. This is the first I have heard of Rondo Energy, so thank you for the introduction. However, I would like to hear more technical details about their heat storage battery. Pros: 1) off the shelf technologies 2) simple, long life materials 3) high output temperatures (compared to other heat storage technologies). I love this part of the solution. Cons: 1) I am very skeptical of the stated 98% storage efficiency mentioned at the start of the video. Usually, when talking about storage technology, people quote the "round trip efficiency", meaning, what percent of the input energy comes out durring discharge as usable energy. However, I suspect you are quoting the charging efficiency, meaning how much of the input energy is stored in the battery, ignoring how much energy is lost durring the extraction process. If you really do mean "round trip efficiency", then this statistic is so outlandish, it really is "too good to be true", and begs for justification and a heavy dose of skepticism. This would be astounding, and much higher than any of the other heat storage technologies. Lithium ion itself is typically stated to have 90% round trip storage effeciency, which is higher than any other heat energy storage technology that I am aware of. 2) There is no explanation of how the heat (ie, hot air?) used after it leaves the battery. I can imagine a few uses, but some solid real world examples would have been nice. 3) There is no talk about the ideal storage charge/discharge cycle time. Is this technology better suited to be used for short term (4 hour) medium term (8 to 12 hour) or long term (days/weeks) storage?

  28. Flaps on landing. Whilst they do increase drag when deployed and therefore reduce airspeed as you say, their primary function is to maintain lift at lower airspeeds. 😊
    366
  29. Hello, the clip at 0:30 is from our 3D printed EDF video. We would appreciate if you included the original as a source in your video description. Many thanks.
    351
  30. Again "slapping a turbo on it" was the solution.
    343
  31. I am an ex laminator who worked with carbon fibre for motor sport, aviation and oil industries. The process of the bonding of the hull to the Titanium caps looks extremely questionable. In the videos I have seen the were hand mixing adhesive in buckets, applying with plastic scrapers in an environment that was not dust or dirt free. Frankly I am shocked it went as deep as it did. Maybe methods have changed but it is not an assembly environment I am familiar with.
    330
  32. It was mentioned that the Titan dropped it's weights few seconds before the implosion. So odds are that they started to hear some type of crackling sounds either from the hull or from the glass viewing window. So the operator must likely dropped the weight to immediately surface but it was too late. The unit was already too far damaged and it gave way and imploded.
    314
  33. 3 percent isnt as bad when you think about how many tons of freight a ship can move.
    309
  34. Quite fascinating. Remember the invention of the blue L.E.D. changed the world as we know it.
    304
  35. Such a cool innovation with a surprising amount of applications! Hopefully they become more cost effective in the future!
    281
  36. Just wanted to make a correction. At 1:57 there's a picture of a propeller that supposedly has cavitation damage. This is actually a picture of a brass propeller that's in the process of being repaired. The outer edges have been welded and the "cavitation damage" is actually the weld that was added to repair the propeller. This will be ground down to match the original shape of the propeller. Thought I'd clear that up incase anyone was confused.
    278
  37. Love to see the effects on massive ships like cargo and cruises
    254
  38. 4:47 I'd imagine the major drawback for larger aircraft is they require variable pitch props and rotary wings. But the concept is fascinating.
    254
  39. I live in Kiribati and I was on Banaba during the drought And we are are tying to facilitate a small drill rig for simple wells; Love your article, accurate, too. The question is : when will it be available ?
    246
  40. The most important metric of a wind turbine is the levelized cost of energy (LCOE). This metric allows you to compare all forms of energy generation in terms of total energy return during the lifetime of operation per investment dollar spent.
    219
  41. 4:22 this has actually been true for all sail powered boats for as long as we have sailed. Sailors want a side wind more than a tail wind. If the wind is blowing behind you to the front of the ship, then the faster you go, the slower the wind is relative to your sail (if you're going 20 mph and the wind is 30 mph behind you, it loses speed catching up to you and hits the sail at 10 mph). your ship will not get any faster as soon as the wind hitting the sail is too slow to overcome the friction. If the wind is hitting the side of your ship and you use the sails to deflect it backwards, you could be moving at 50 mph and you will still have wind hit the sail at 30 mph.
    201
  42. regardless of what you think about Elon Musk, you have to respect the man for generating so much hype about electric vehicles and a renewable future.
    199
  43. Thank you for mentioning the downsides of cycloidal rotor propellers as well
    194
  44. Cavitation also is responsible for a great deal of wear and tear, shortening the service life of a propeller. Given that even smaller propellers aren't inexpensive, consider replacement costs on a cargo or military vessel.
    194
  45. If you want to be blown away about some of the limits of flywheel / gyro tech check out the specs on NASA mission Gravity Probe B. Its gyros were so sensitive they could measure the phenomenon of “frame dragging” which is the literal dragging the fabric of space by a moving mass. Everything about that mission is interesting worth looking up if you’re into that kind of engineering.
    192
  46. Having different colored and designed kites could make it a nice tourist attraction too. If our energy production can also be an art installation we can inspire people with a more creative side to get into energy production.
    181
  47. Great Video Ryan! I love the point you make that solid-state isn't the goal, its higher density batteries and lithium anodes... It's fascinating in science and engineering when we develop one type of technology for decades, only to see it surpassed by some new contender no one sees coming.
    181
  48. amazing how many designs that we previously thought were so efficient, have still so much to be bettered.
    162
  49. Flywheels made of depleted uranium have also been used in energy storage and are used in the primary coolant pumps of nuclear power plants to ensure a long coastdown in the event of a power failure.
    160
  50. I did my dissertation on tubercles, the effect did not seem to be a primary effect of vortex or mixing as would seem intuitive but having a wing with a blend of chord lengths. This in effect smooths the lift/drag distribution so that the wing does not perform as per one specific aerofoil geometry but a blended solution of the chord ranges. This is not so useful for lift generation which can be designed for specified efficient parts of flight but it is useful for maximising the Angles of attack a control surface can be used at - it is not surprising in the end as the humpback whales use the fins for rapid turning and mobility for prey catching, not propulsion.
    154
  51. If you shape a whole building or skyscraper using the same principle... probably that could generate a lot of power?!
    152
  52. Unbelievably cool and useful. How did no one think of this earlier. It's amazing how we keep finding new improvements. I'm so excited for the future!
    148
  53. A tip: instead of comparing RPM, compare peripheral speed. Speed to material strength ratio is constant wrt size, while RPM have an inverse relation to size (for the same material strength).
    142
  54. Hi Douglas! 1) The roundtrip efficiency of basically all electric thermal energy technologies will be in the 95%+ range. Rondo's roundtrip efficiency is 98%. Our system is designed to minimize environmental losses via insulation and recycling air. 2) The energy that leaves the system (hot air, superheated air, or steam) is sent into a facility's existing heat network. We're a plug-in replacement for existing gas-fired boilers that are using the same networks. Large heat loads and heat networks are common in the steel, cement, food & bev, chemical, low-carbon fuels, mining industries and beyond into non-industrial uses like district heating. 3) This is a long duration energy storage solution, the Rondo Heat Battery retains its charge for up to a day.
    137
  55. As long as it's not in the atmosphere as CO2, carbon is not a problem so yeah that's the idea. And it's a genius idea, especially if they use carbon from carbon capture
    133
  56. I just finished my Fusion Student days ( I guess I am more or less the same age as you) and I approached this video with my spider scam sense tingling... I did not know your channel... Well.. the scam sense was wrong... Good job man, this is a nice video with proper scientific backing data and sources mentioned. I do not agree with the background message that "they are not telling us" ... there are lots of papers focused on the breeding ratio problem... you also mention some of them... But I guess that youtube videos must have a catchy title and claim ;)... But still... a great video! My compliments! It left me with the thought that I may even be up to help you out on similar projects ;) In the meantime... Keep it up!
    131
  57. I can definitely understand why Google is interested in cheap clean energy. Their server farms take up an enormous amount of power. It would be nothing but good news for them.
    126
  58. I did an engineering project in high-school back in 2015 on this very concept. My mind is blown that it actually functions.
    126
  59. Nominative Determinism
    118
  60. I love the fact that you show actual calculations! You're going to be big friend!
    116
  61. Didn’t know wave energy had been investigated for so long
    115
  62. Another minor benefit is that having a horizontal rotation axis makes it easier to balance torque with a variety of rotor configurations.
    113
  63. Congratulations on handing in your thesis! Writing these can be intense and I hope you're happy with the outcome!
    104
  64. The pedantic- the motor does not bend physics, the physics bends it.
    104
  65. Didn't this pop up in Big Hero 6?
    102
  66. I've never heard so many different ways to describe massive pressure being applied than I have over the last few days. A lot of them seem to include elephants 😂 yours was particularly interesting. Thanks for making this. It was great.

  67. We had an experimental desalination project on town land near the shore. It used only solar to evaporate and distill seawater from a shallow black polymer lined ponds. I never did learn the results or prospects from the project. It lasted about four years.

  68. In my view, the biggest problem with wind powered ships is “Just in time delivery systems”. For that, material has to get there quickly. But other things, such as oil, ores, etc, could be considered as being on a conveyer belt system. . . Wind Powered ships would fill this requirement very well. The irony, of course, is “Oil”.
    98
  69. A problem you forget with geothermal energy is that you subtract heat from the rock and the rock is not a good thermal conductor. That means that a certain pipe has only a limited energy capacity until the rocks are cooled down enough so that the water will not be supercritical.
    96
  70. No mention of hydrogen storage? How much bleed off is there? Is the tank in an aircraft somewhere in the fuselage? The tech sounds good but there is always the problem of keeping the fuel at super low temperatures.
    95
  71. I have never been so invested in a conspiracy for an energy project
    91
  72. Alternative energy storage technology is a very interesting toppic. On the vid side itself. Clear presented, flowing script without any "breaks" in the narrative. Well chosen pictures for visual representation and the audio balance for voice vs background music is very well done too. Nothing to add but a round of praise.
    90
  73. 9:09 you are welcome for that 1second of footage from my backyard.
    87
  74. I like how he's also literally taking carbon out of the carbon cycle to make these heat reservoirs. The IR mirror returning unused photons back into the reservoir is genius.
    86
  75. Great research results! Maybe the same method could be used to avoid clogging in flow batteries, too?
    86
  76. 3:58 Why is it bad that the batteries are manufactured in China? When you buy an EV, someone has to make the battery. China generates the most renewable energy and more strict emission standard
    82
  77. even bots love your videos
    81
  78. Neil Armstrong's testing of the X-15 is still to this day one of the most harrowing experiments in aviation.
    79
  79. 4:40 Conveniet, yes. More Efficient? No. Induction charging is less efficient, there are loses that are bigger than on wired charging systems. Many of the clever engineered benefits that wired charging brings are discarded. Oh he corrected himself at 7:10 atleast in what way the motor is concerned. The new Mahla motor is impressing. Especially how they solved the issues that come to mind with this type of electric motor. I just want more hard stats regarding the motor, guess I will have to read the document from mahla.
    71
  80. That's why a golf ball with dimples, travels further compared to a similar size ball with no dimples. It seems rough over smooth appears counter-intuitive, but there is definitely some hidden secrets we can learn from nature.
    71
  81. Compared to pumped hydro, this has very close to no potential.
    69
  82. Just loved the Scottish engineering manager, Mr. Gibson, attitude: “having our design copied is a great compliment” 😁👍
    67
  83. "13 subscribers" LOL he do be boomin tho
    64
  84. Elon has stated that it will only have a weight penalty of about 1000lbs and potentially get down to zero difference.
    64
  85. 2:34 small correction: quadratically not exponentially (i.e. v² not eᵛ)
    62
  86. That's mad, always love me some efficiency. Hope these become the norm in the next 5-10 years! Less of an issue than the other aspects in the majority of cases, but would be interested to know if they are less (or more) durability in the instance of hitting something.
    61
  87. I’d love to see you do a video on the LiquidPiston rotary X-Engine. It looks very promising, with over $30 million in military funding, multiple scientific papers outlining technical details of the engine, and plans to begin delivery to the military and later to civil markets within the next year. To my eyes it’s the most promising new engine design floating around
    60
  88. This has some really interesting possibilities for micro-pumped-hydro-energy storage. Also great video, well presented.
    59
  89. This is why I love this channel. Brings to light technologies that I haven't heard of or are unfamiliar with and gives a wholistic analysis on pros, cons, and possible outcomes. Been a subscriber since Day 1 and I'm still loving it!
    56
  90. So impressive, your video quality has skyrocketed. 55k subs. Astounding mate. Keep it up, I use your vids in my engineering circles.
    51
  91. I'm pretty sure that the "three times the emissions of a petrol car" figure was per passenger mile.
    49
  92. This sounds really good! Hydro is the way to go if you can and microhydro gets too little attention. I am glad to hear that the propeller is fish safe too!
    48
  93. Damn, got to promote AMD congrats broo.
    47
  94. In theory having the entire length of the blades at the same speed offer better efficiency, but you lose a lot because parts of the cycle isn't producing trust.
    46
  95. Just want to say that you may be one of the most under appreciated researchers there is! Love you and keep up the fantastic work!
    43
  96. There is one particular problem about putting it on top of buildings, if you put this on top of a house often times it's going to act like a sail and capture some of the wind giving it a little push. the problem could come about if the roof of the house is not reinforced to take this extra pressure, it could cause it to slowly over time degrade the structure of the roof or cause a failure bringing the roof down either on the building or pushed to the side
    41
  97. I was tempted to “pre-empt” your video, but decided instead to listen right through. You are absolutely correct about the lithium breeding issue. It is an area that has had too little “investment” of technology and effort because the current strand of research is focused on - 1. getting stabilised plasmas 2. Establishing a “burning” plasma with all of the potential additional stability issues associated with a burning plasma versus a non-burning plasma. 3. Getting the required gain in thermal efficiency - I.e. more nett power out and than power used to establish the maintain the burning plasma 4. Running the plasma for long enough to be a viable producer of energy. All of which problems are still yet to be resolved. And until they can be, the next phase of a “production prototype” will not be financed by anybody. It is during the “production prototype” phase that the breeding issue will need to be resolved- alongside many very serious metallurgical problems that many scientists do not yet realise they are going to face. (or maybe, some do, but are deliberately keeping quite about these so as not to throw a spanner in the works of the development efforts). My personal opinion, for what it’s worth, is that these issues will hold up the introduction of fusion reactors for a longer period of time than that taken by the physicists and engineers to establish a burning plasma. But many in the industry think that taking the energy from a fusion reactor will be as straight forward as doing so from a conventional nuclear fission reactor. Technology which is well established. Again, my personal opinion is that you are comparing chalk with cheese. But, on the bright side, I think the problem is a “nut that can be cracked” if there is enough investment in the research. ITER may provide a number of answers - but to be honest, I think that ITER is now as much a costly white elephant which is diverting money that could be better used elsewhere - as far as fusion research is concerned. Again, my opinion, is that nuclear fusion will be solved and developed by private initiative - not through a project such as ITER. There is much evidence that this is happening already.

  98. With the Jesus lizard prop, that looks a lot like a voith-schneider turned on its side, you should check those out! They're not super common, but sometimes used in ships where a lot of thrust is needed in all directions, like tugboats. ABB recently unveiled the Dynafin that was inspired by whale fins, or so their marketing dept claims lol Also I have a soft spot for super-cavitating props or chop props, which is an interesting way to work around the cavitation issue. They're basically only used in race boats because they're only efficient at very high speed
    40
  99. Rock at this temperatures and pressures (at 10 km or below, provided the right spot is chosen) is not like the rock here on the surface. It's actually getting softer and even partly melts, a bit like thick, highly viscous magma with solid parts in it, having quite different thermal conductivity. And there are saline fluids which also can transport heat. Of course there is a limit, but with the right amount of water pumped in, there will be little issues with keeping it hot. But there are other issues. In case a non water-permeable layer of clay is penetrated, and water spreads into formerly dry layers below (e.g., into Anhydrite), those may swell, raising the land above quite a bit. This already happened, and it literally ruined villages. Such issues are hard to predict, because of the actually unknown structure details and porosity of the rock below. Another issue is liberating toxic substances from under ground that were kept there before, e.g. heavy metals or radioactive material. And in case of a movement of the (softer) rock below, the pipes may easily get crushed, posing another issue. We actually don't know very much detail about the earth's mantle, as it is hard to just go and have a look. Thus it is difficult to chose the right spot to drill.
    39
  100. This is a GREAT introductory explanation of fuel cells. Thanks.
    39
  101. More of these deep dive detailed engineering topics please. The more challenging the better.
    38
  102. If the current pace of development continues. I think electric planes will become a more viable solution for short flights then hydrogen. However I still think that hydrogen planes will be better for long flights because the burning of fuel decreases weight.
    38
  103. I am astonished by the amount of views on this video compared to the amazing quality of it. Keep it up, mate. Hopefully one day you will get there.
    36
  104. really good, indepth video.... id like to think that hydrogen is the future unless now "traditional" battery production methods can be made better. However you mentioned the t.50 was mclaren, it is actually made by Gordon Murray Automotive, Gordon Murray designed McLaren f1 cars and also designed the McLaren f1 road car, so it is easily confused : )
    36
  105. I've seen this design doing the rounds for while now and whilst I used to get excited by new wind turbines whether vertical or horizontal or 'bladeless' like this, it becomes clear that wind is a tricky thing to deal with - solar on the other hand is more accessible in that you know what you're getting provided there's no shading or obstructions - the amount of radiation may change from day to day and location but it's tried, tested and "solid state" so no maintenance - I often think new products are introduced to market on the basis that the company will have ongoing income through maintenance contracts - sounds cynical but every "small" turbine I've seen on the market that then appears in real life ends up shelved after some years nowhere to be seen again apart from the odd early adopters...
    35
  106. If I could buy stocks on a YouTubers potential growth rate I would sell all my Tesla and Apple and buy in on you
    34
  107. And what about Regenerative Braking? Given the weight of the vehicle itself and the load in the trailer. I think so much energy can be put back into the batteries⚡⚡
    33
  108. Pretty amazing content for such a young channel, subbed for sure!
    31
  109. They definitely need to tweak the flux capacitor.
    31
  110. The ribbed propeller reminds me of vortex generators on an aircraft wing. The trick to fluid dynamics is balancing the tradeoff between lift/drag/weight and thrust. I love this presentation!❤
    29
  111. The thing is, industrial espionage has existed forever... EVERYONE DOES IT whether it's literal theft from seeing something or patent rejection and copying which Thomas Edison was fond of doing. I really would like to see a deeper view at the Chinese project together with size comparisons as they may well have copied it and later improved upon it.

  112.  @brettmoore3194  Boron - Proton takes 9 times the temperature (on absolute temperature scale) as DT, we probably will never do it in sustained power generation.

  113. ​ @ErikS-  I am an engineer with 30+ years. You-re right he lacks a lot of experience but from my past interactions with him on this channel he is UNLIKE SO MANY OTHERS willing to engage people who know more than he does. As a counter point so you know what I consider good and bad science and tech channels. A while back I corrected a fairly basic mistake made by the Common Sense Skeptic who's a real Elon Musk basher and being honest he's well justified in bashing Elon. But on this one video where they were trying to promote a long forgotten and dismissed alternative to getting into space I corrected them on a point regarding air launched systems. FYI - My degree is in aerospace and I knew what they said was 100% WRONG. I got a damn arrogant reply telling me I didn't know what I was talking about and should remove my comment. I then replied back and sited all sorts of examples PROVING their comment was wrong. They then deleted me from EVERWHERE on their pages. So YES Ziroth is young he does lack experience BUT IS WILLING TO LISTEN while so many others are pretty SHlTHOUSE.

  114. This is an excellent account of some of the issues facing tritium breeding, but one could add the problem of tritium escaping the reactor. This seems inevitable given that the tritium will be bred from lithium based material in a hot environment and that adequate tritium diffusion barriers do not exist. Even the relatively low tritium levels in the Canadian Heavy water reactors give rise to tritium loss to the atmosphere.
    26
  115. And at 2:05 the computer model of the prop is nonsensical, as the pitch at the tips is greater than the one at the root, while it must be other way around. The prop shown is basically in a "feathered" position.
    26
  116. Please don't choose to add the loud clicking effect. It's purpose is unclear, it comes abruptly, and it's volume is distracting. Otherwise, thanks and congrats for another succint and interesting video
    25
  117. Nice idea, I'd like to know the cycle live of the fluid wouldn't there be a quality issues at the filling stations mixing varying quantities of different aged fluids though there live cycles.
    25
  118. The piston Rollers on the Swash Plate, or Wave plate, are not that much of an issue. Roller bearings on the crank shaft of ICEs use to be very common on Race car engines and some road cars, particularly French cars such as the Citroen DS and SM. The effect was much better performance and longer life. Although this came at increased cost and modern metallurgy and engineer made roller bearings on the Crank mostly unnecessary. But in smaller engines remain their most useful. Maintenance was simple enough. Just change the engine oil when you are supposed to and the roller bearings would last pretty much forever. And this is NOT making concern of roller bearings in the Valve trains of many ICE-vehicles. Again just change your oil and it is not a problem. So, in the E-REX, the roller bearings should not be a problem at all, as long as the bearings are of good to high quality. I would have however preferred if the engine was presented with less showmanship and more straight the facts.
    24
  119.  @ZirothTech  Sorry, I didn't want to come across as too critical, I think you are doing very good job with your channel! I completely agree that fusion start-ups hide a lot of issues related to fusion (by doing so they are harming the cause for short term monetary gains)! Out of ~40 fusion start-ups maybe 5 are onto something and out of them maybe 2-3 have a really solid plan (i.e. SPARC). First fusion reactors will most likely use D+T but a mature fusion technology would have to use different kind of fuel (a bit of a futuristic perspective) to avoid all the issues you pointed out in the video. Keep up the good work!
    24
  120. They should use this with a high voltage wire when training on the tether, would save a load of fuel and emissions.
    23
  121. This is the kind of ingenuity needed for solving energy storage! Great video, and thanks for sharing!
    23
  122. Thanks for this interesting explanation along with the interesting fish-friendly propellers Ziroth. By placing big rocks all spaced along the waters edge this will considerably slow down the bank erosion as well making it truly nature friendly.
    23
  123. You're seriously stepping up the editing game!
    23
  124. Cheeky face reveal ;)
    23
  125. There is no such car as the "McLaren t50." It's the GMA T50. GMA stands for Gordon Murray Automotive. Gordon Murray designed the McLaren F1 and has described the T50 as "the logical successor to the F1." Think that's where you're getting confused. Otherwise, nice video. https://gordonmurrayautomotive.com/en/
    22
  126. Interesting video. And nice to see your subscriber numbers grow. It'd be interesting to see a short channel update about that from time to time. And it would also be interesting to see more about reinforcement learning. Especially how this works on a computer system, when rewards and punishments seem to make sense only when some kind of feelings are involved.
    22
  127. It was more theoretical while I expected for real projects or prototype as in thumbnail.. Overall great explanation! Keep it up 🤘
    22
  128. Really interesting, please keep covering such topics.
    21
  129. This is the first time I have heard of liquid flow batteries. Fascinating stuff. I look forward to seeing future developments of the technology.
    21
  130. It's just amazing how after years and years of trying to do things our own artificial ways, we always wind up finding the answers in nature.
    21
  131. Masters degree in physics here. I enjoyed this video. You taught me some terms from the industry and explained it quickly rather than going over the absolute basics you presented something new around AI applications and what’s happening. Appreciate it
    21
  132. I'm dubious about the claim that reducing the wind wake can "suck in" fast air from above the wind farm. The slow air still has to go somewhere, contrary to what the graphic at 8:58 suggests. At best you can spread it out to 5 times as wide and 1/5th as high as the blade disk of the wind turbine or so. Yes, it will help in the case where the next turbine downwind is exactly in the path of another turbine, but now it will actually reduce wind speeds when the next turbine is within that 5 blade disk wide wake, making wake problems 5 times as likely to happen. And after 5 consecutive turbines have sucked in and spread out the wake, you're back to about the same wake height as before. But maybe this is just a cost saving measure as well. 5 times as likely wake effects of 1/5th the strength will reduce the maximum dynamic load from wake turbulence to 1/5th. I just wonder if wake turbulence adds that much of a load compared to natural air turbulence in rough seas.
    21
  133. He wasn’t joking when it literally appears everywhere. Wonderful video ziroth
    20
  134. Massive thumbs up for you beer analogy and I've even subscribed to you. Nice work on your content
    20
  135. you're teaching me about so many types of propellors, literally couldn't think of the type of designs... amazing what innovation can do, thanks! :)
    19
  136. if you want revs out of an electric motor you reduce it's radius and increase it's length, the closer the magnets are to the center the faster they can spin, I have small electric motors that reach some blistering speeds upto 100,000 rpm using that principle, so i'm quite sure bugatti can too.
    19
  137. Good report even got the nO2 issue. You didn't mention storing the fuel as a hydride is more energy dense than a liquid. And a turbine is the wrong way to use the fuel a fuel cell will do twice the efficiency.
    19
  138. I think what Helion is doing is more promising. The NIF setup simply proves what we already knew - that fusion on earth is possible and that done correctly you can get a net gain in energy. What this facility will never do is repeat this several times per second and sustain a chain reaction so we can actually use that net gain in any meaningful way. The ITER plant is in the same boat in my opinion and I think we should be starting backwards as Helion are doing and focusing on how to use the energy we gain
    19
  139. Thanks for the update! I really like that you keep the level of sensation in your titles at a reasonable and defensible level, and how you explain the scientific background. Keep it like that please! However, one question: 3:49 isn't it rather that, with a temperature gradient, the density is higher on the cooler (low-pressure) side? I'm thinking about the ideal gas law. Or are there other relations for plasma?
    19
  140. 1,800 hp, should be enough to get to the supermarket
    19
  141. It would still be great to have supplemental source of, let's say, 2kW of wind to roof-top solar. Just the fact that it can produce some energy in the night, when you normally only use grid or battery, would be great. But having rotating turbine on the roof is a problem... So even with 4.2m/s winds inside the city, the aesthetics of the thing would still overrule the efficiency, I guess.
    19
  142. I can't wait till we hear that we got 10% extra power from what we put in a fusion engine! Obviously that's not much but it's a huge step regardless, but when it happens it'll be big.
    19
  143. Really well-made video. You made the science of all this sound interesting and more accessible. Normally a lot of people when discussing things just say opinions but here you actually supported what you were saying from actual research. Keep it up man!
    18
  144. FYI: Alaska Airlines is NOT a "regional" airline. It flies internationally. Not a complaint, just a correction.
    18
  145. Cool video, but it could be longer and more in depth. I feel there were some better ones. Keep it up!
    18
  146. Loving the history/mythology crossover/backstory. Another great video!
    18
  147. The inner kid in me is so happy to see so much research & testing being done around Biology inspired designs. Then Add in our advancements in material science, engineering, software performance testing methods, etc. I really think we are going to be surprised by what we end up developing. Each development could be unique and useful in different ways. For different tasks and so on. It's just awesome to see so much curiosity and development being combined in this field of productivity.
    18
  148.  John Jack  lmao. Imagine being the ordinary bloke from UK who runs this channel reading that people think he's with the CCP.
    18
  149. Another great video. Gives you hope that one day soon even the most ardent anti-EV folks will have no leg to stand on when it comes to range and time spent "filling the tank."
    17
  150. Carrying material in the air before depositing it on the structure costs a lot more energy than a crane or a giant printer no ?
    17
  151. I am going to see if I can get a few 3D printed for use in water pumps. Efficiency is critical when working off the grid. Cheers
    17
  152. On the shoulders of Giants, nothing was created, only they realized by taking two existing technologies and focusing them into one, they were able to combine them to make something solve a problem. Good for them! I hope this is a step int the right direction for mankind and our Planet! Thanks Ziroth, I really enjoy your videos.
    17
  153.  @korus7670  We don't intend to strike a video because it uses 5 Seconds of one of our clips. Credit would be appreciated however - thanks guys.
    17
  154. Great video! You deserve more subs!
    16
  155. Yes we can capture all the heat, and no we're not turning that heat back into electricity! Industry requires hot air or steam for many processes, most of which use natural gas today. Rondo eliminates scope 1 and 2 CO2 emissions and there are no NOx SOx or particulate emissions.
    16
  156. Good Video. Like your thinking out the thrust vs weight to determine if this is any where in the range of feasibility. Haven't checked your numbers and process but the logic is clear. Additional critique of the original study: Innovative measurement but no proof of calibration in the paper. Device could be producing more thrust per power (or less). Something tells me it is not far off. Good opportunity to add to what the authors have started. Also, the shape of the tube and other adjustments may add efficiency, another opportunity to add value.
    15
  157. Like everything else we've ever used, it's only waste until it becomes financially viable to re use it. Right now there are huge stockpiles of Thorium being treated as waste. Research by many companies is well under way on how to use this to bolster Uranium reserves and to use up existing nuclear waste as fuel. It's not a waste facility. It's a resource storage facility.

  161.  @ZirothTech so a single piece two blade rotor to be precise
    14
  162. Given most places like Kiribait are close to ocean level, the average humidity of the air is high... so I'm surprised they're not looking at atmospheric water capture... No need for brine disposal, direct clean water etc... Might be a good area to read up, @Ziroth
    14
  163. Would be nice to see a toroidal-bionical propeller eficiency test results!
    14
  164. Excellent video
    14
  165. Question: if this design is so good then why won't the Brits invest in it themselves?
    14
  166. First time I've seen your channel. Thank you so much for not being a TTS spam account. Liked. Subscribed. Commented. You deserve more attention than they do
    14
  167. Amazing content as always, thank you
    13
  168. This sounds like such a promising technology!! And amazing video as always
    13
  169. this could be huge, hope it works in mass production
    13
  170.  @ZirothTech  so tell us what does the UK produce nowadays as compared to the factory of the world? comparing an apple to a raisin to justify your point doesn't make any sense....
    13
  171. its new to most people though. i think its fine
    12
  172. Dead end: The energy required to produce the gamma beam will exceed the energy produced and converted into electricity from fusion.
    12
  173. This is a great idea! I've lived near and driven alongside many miles of these canals and can say that almost none of them are picturesque, so their appearance couldn't be harmed by the addition of solar panels.
    12
  174. Congratulations on starting your PHD! Your channel produces great content - you're going to do great!!

  175. Hi, I am from the future....I recently travelled from Earth to Mars and back using the power of a single AAA battery. I copped a lot of flak for being wasteful from my peers who can travel to alpha centauri and back 13 times on a single AAA battery

  176. Their problem wasn't that they didn't have enough light, but that they are waaaaaaaaaaay too bright and damaging to eyes. Leaving a blinding afterglow in the form of stripes and arrays of dots. People with astigmatism literally can't go on the streets safely anymore. The orange sodium glow is less visible so it's also less hindering to people with astigmatism, but white and blue leds will overlay an opaque layer over everything. Oncoming traffic sometimes forces me to just stop because I can't see anything. Glasses don't help against astigmatism either, it requires risky surgery.
    12
  177. I need a few of these. I need them for medevacs for Puerto Rico. The roads are often impassable after heavy rains. I could go from the campo to the local ER. the ride by van might injure the patient more
    12
  178. Another thing that is important is long term storage. Like for solar, you have a huge amount of energy generated in the summer but not as much in the winter. Lithium-ion batteries could have a hard time holding their charge over an entire winter. But with gravity storage, they should have no problem keeping their “charge” or potential energy over these longer time periods.
    12
  179. Sounds easy, sounds like a great idea, but geothermal plants are nothing new. Financially speaking, most only produce a very small amount of energy. One major cost hurdle is corrosion. There are some pretty caustic chemicals trapped in the Earth's crust. I have many geothermal plants around me (closest is less than 1 mile). I've seen expensive and exotic pipe material get eaten away by corrosion in a matter of a couple months. I congratulate on a nice presentation, but you have to take much more into consideration. There are theories and there is real life senarios.
    11
  180. Really cool use of reinforcement learning! Thanks for another great video :)
    11
  181. Perhaps these devices could also help with storm surges? Very interesting video!
    11
  182. I like your approach by the general background instead of jumping on the "disruptive sensation" train, well explained and simplified, but still widely correct.
    11
  183. Very interesting and I think the rollers can be made to be reasonably durable as the change of direction would not be as severe as that of a crank because of the geometry which might reduce the shock enough so that ceramic bearings could be used.
    11
  184. If there's a way to mitigate or eliminate the production of nitrous oxide, this could be a viable option. But as things stand at the moment, fuel cell propellers might be better suited for short haul flights. Nitrous oxide is 300 times more potent as a greenhouse gas than CO2 and is also toxic to humans. I'm interested to see how one might eliminate NOx from the combustion process.

  185. 3:10 more energy => higher frequency => shorter wavelength

  186. I'm on a solo trip to Japan and literally wondered about it today. Didn't search nor talk about it with anyone. It's scary how the algorithms seem to read our minds.
    10
  187. And a electrical generating fusion power plant is still 20 years away,,,,,,and always will be. Thanks for this level headed video.

  191. At first I thought it was real and I was very excited, then I realized today is April 1st so this is probably an April Fools prank, and now after watching this I don’t have a clue about if the future is in matrices or if the surface is where we stay. Science. Jokes aside, really cool discovery you talked about here. Wonder how this research will be used in future applications now that we are becoming more aware of the necessity for clean, safe, and long-term solutions our energy consumption intra-planet and even maybe one day inter-planet.

  193. 5:38 your demonstration of the principle of work and a machine was excellently brillig!
    9
  194. It's quite an interesting car that show us the importance of computer assisted design and improvement through technolgy advances, maybe the numbers barely make it right now but imagine in 5 to 10 years, this could be the form factor of the future. Great content man! Love the style and the themes, keep it up!

  198. In one of their FAQ sections, Aptera said that they used "NREL" ( National Renewable Energy Laboratory) data, when creating the solar production calculator on their website.

  200. Good analysis. In most cases it would be better to build big wind farms with big efficient wind turbines than small scattered inefficient turbines on individual roofs.

  206. Congrats on the Phd thesis submission ... whew! Weight of the shoulders for sure! Regarding this video, airborne wind turbines seem like an exercise in frustration for its developers though I wish them well. That said, I wonder if wave or tidal energy systems might be a quicker path to more reliable/economical electricity generation. Thanks for covering this topic and thanks for the wind turbines in your background shot. Nice touch! lol
    8
  207. Oh the quality improved drastically in this video - cheeky from u Ryan
    8
  208. Great ideas. And, like a lot of things, it will probably become more practical with time and effort. I would not call this "renewable" energy, though. Maybe an [essentially] infinite energy source, unless, of course, the Earth's core renews itself. Thanks for posting this.
    8
  209. Super intriguing, good to see some tangible options coming through for fusion.

  210. Thanks for being normal, informative, concise and non-clickbait. Unlike 90% on this topic. Subbed.

  211. Wow yeah for hybrid aircraft very soon this cooling oil will be extremely important presumably! Many aviation and other applications for all of this!!

  218. Might work for preventing coastal erosion too. A few rows of those parallel to the coast should be able level the waves.

  219. Come on...let’s not scale up. Let’s scale down. Give me a plasma lighter. For the time being, that’s the best we are going to get out of this tech here on Earth!

  221. The cadence of your narrative is much better then the often manic pace of many other video narrations. Interesting stuff and it seems clear that creating propulsive force from electricity has a long way to go become commercially viable. Flying drones powered by this technology may be the starting point.
    7
  222. Great video. I was following the helion project as well. I suppose we are on the cusp of commercial fusion energy viability.
    7
  223. Keep up the great work your content is amazing!
    7
  224. We need nations to be encouraged into experimenting and sharing the costs of developing projects to reduce emissions. The flip side of that is that capitalists will always capitalists and if emission reduction projects were open source, they'd not engage, or engage fairly, unless they where allowed to capitalise and make massive gains from it and ensure others couldn't. Monopoly Capitalism will always see projects crawl along and lobbies will always be there to ensure the pioneers are held back.
    7
  225. But the rotor requires DC current to generate the magnetic field, while the wireless transmission only works with AC. How did they solve that? Full bridge rectifier in the rotor?
    7
  226. Honestly, man, you have some of the most interesting videos I have seen on youtube. I would love to see more frequent video uploads from you (assuming this is possible). Keep up the great work!
    7
  227. Very interesting and nicely explained. 👍
    7
  228. the carbon cost of the unit is surely much lower than conventional turbines as well, less maintenance and a much longer projected life with easier maintenance has to be factored in.
    7
  229. I am conviced...to never invest in Energy Vault.
    7
  230. it's best to not call it reward/punishment, it gives an extremely inaccurate impression. the AI is optimizing for a "reward function", it's not actually a reward like a treat for a dog. it's just a value where larger=better. the AI is simply designed to try and obtain the largest possible value, and researchers make the value awarded correlated with the real world result we want, therefore the AI achieves something aligned with our goals. that's the idea
    7
  231. The fundamentals of design were public. No challenge was made to patent infringement. This is slander based on nothing but bigotry and prejudice.
    7
  232. Nice one! If you're looking for similar topics to couver in the future, a follow-up on the Finnish disposal site would be interesting. Especially the technical aspects of storing the waste, precautions, safety measures, and long-term operation plans.
    7
  233. Suspicious? Maybe ... but YES to another tragic story of an innovative Concept ideaed, designed and developed in europe, that did not get established. Today so may "climate specialists" call for innovative ideas to make all over green energy, but 10 years in the past, no one was willing to invest in a technology, that would have now be probably releasable to the market.

  234. It just means it's five times more efficient than normal electric airplanes. No perpetually motion machines involved

  235. Very cool video. I do love the guy but I wish Elon would focus more on creating cheap, environmentally friendly vehicles for the masses rather than crap like this though.
    7
  236. If you haven't heard the story of when he crashed and his only injury was the eject caused him to bite his tongue... It's worth more research :)
    6
  237. Isn't the load factor accounting for the day and night cycle? Bacause in the conclusion at 6:23 it says the monthly load factor. Also if you would have a solar panel which is rated at 730 watt and getting only 33% of the wattage at clear daylight would seem very little unless they account for the nighttime which would mean that the maximum load factor is around 50%.
    6
  238. 4:20 Talking about making nanofibres from living tissues gets me thinking of fantasy sword names as Sword of Oak or dagger of the Crow. I think i heard some metalurgist say that incorporating those nanostructures as carbon in steel (carbonizing them first) helps the strength as there will be billions of nano lattices retaining the organic structure used -i.e. natures bone and tree structures are strong. I have no idea if this makes any metalurgical sense and I don't remember where I heard it.

  241. I remember a video from years ago Someone converted a car ac compressor into an ice, very similar to this one except combining two compressors in opposing manner. Good job.
    6
  242. That's not true. The levelized cost of solar is lower than most other forms of energy. Wind and hydro are sometimes cheaper in some places. But that's the actual issue with hydro power: you can't put it everywhere. Solar works basically everywhere. Even in Northern countries like Germany, it has become the cheapest form of electricity.
    6
  243. What a mis-informed comment !
    6
  244. Thank you for covering this breakthrough. I hope it makes it to the next stage of development and can be scaled up. 👍
    6
  245. It would be interesting to see installation and maintenance costs from a trial run. At least in the renderings, it looks like the panels aren't pointed in the optimal direction, and it would be great to know the actual cost of keeping the panels clean enough to work properly.
    6
  246. Thunder foot literally exposed the flaws in this " future energy storage device " two years ago.
    6
  247. What about using golf ball dimples on propellers like was done on Mythbusters to improve MPG on a vehicle? Add that to the whale design then see if that does anything more for efficiency and noise reduction.
    6
  248. No, unfortunately Fission and Fusion are only energy positive when going towards iron, imagine pushing something down a hill, your going to have to put more energy in if your trying to go uphill. Edit: This is also why stars can't survive with elements heavier than iron, they can't fuse it anymore so gravity takes over

  253. Yeah sure, the fact that a burglar entered the facility and took valuable information two months after the visit of Chinese business men is apparently just a coincidence. Also, kinda weird how the burglar knew exactly where the information of the design was, is like someone who was there before told him where to look.

  263. Vehicles like this or similar, designed to reduce consumption, MUST be the future. It's great that big companies are finally developing electric cars, but if they weight 2 tons, following this SUV fever, we're not moving forward, and we can't afford following this trend any longer
    5
  264. The one shown on the roof seems to work a little different, with the rounded divider between the airfoils and the turbine visible beneath. The divider may cause an extra low pressure behind it, sucking up air from the bottom, making the turbine spin.
    5
  265. if it is driven only 30 miles per day, it means it is parked 23 hours of the day. they should design it with extra solar panels that stores when driving. but fully extended when parked. This will easily double the wattage of the panels.
    5
  266. Love the videos, super interesting stuff! Keep it up!
    5
  267. Hey can you do a video on why different car manufacturers uses different voltage systems for their cars? For example Teslas use 400v while the Porsche Taycan uses 800v. What advantages and disadvantages are there by using higher or lower voltages?
    5
  268. What we really need is urban design that discourages and penalizes car use, both ICE and electric (especially for distances between 0-15 kilometres, which is also highlighted in the video at 3:52) and promotes other mobilities (especially walking and cycling).
    5
  269. It's always nice to see a channel grow...I remember I subbed when you were a tiny channel and had like 3k subs. One day I hope to do the same with my own channel. This turbine is amazing too, glad it saves the fish.

  270. What about the tritium dilemma? How will nuclear fusion ever be economically feasible if the fuel necessary for the reaction is so rare and expensive? 😟

  276. Cool video! May I request a video comparing Tesla's EV semis and Nikola's hydrogen fuel cell semitrailers?
    5
  277. For the most part thats cool however fast growing plant with similar cellulose structure would be better as we could farm it and keep the ecologist neutral. A gene modded Bamboo or something.

  281. had to geek on this a bit But the battery wouldn't have depletion this would work for continuous flight we have small wind fans that produce allot of electricity to recharge and solar panels that can recharge during day flight and they would catch a better rays anyway when above the clouds this is the future 👍

  284. Cool overview video, saw a few cyclos I built in there!

  285. Really interesting video, I hope electric vehicles get through the mill of procrastination. Having 700 miles of range is definitely not necessary for most smaller countries. In the Netherlands for example you would only need about 350 miles range and that's already in the luxury range. You could just work closer to home, but that's also a per-country and per-person variable. The masses still don't need 700 miles of range, it's a luxury, even in the USA. And if you do need more, it's cheaper for you and better for the environment to then just use a combustion engine. At least until the markets and resource prices shift again.

  287. Right to repair?! Now im in!

  288. Good video. Maybe one thing to add: The sun, by its UV radiation, may help to keep the water clean and stop growth of algae and bacteria, for example. Thus, blocking out the UV light might as well be disadvantageous. But that's probably not a major issue.

  292. Ordinary current desalination at scale is already 10x cheaper than tap water in the U.K.

  293. Interesting concept but as with ANYTHING in aviation, it has to be SAFE, robust, somewhat easy to maintain. I don't think you will see this technology on airliners any time soon. It has some promise, but flaps and aileron are critical surfaces that have to work EVERY time. A failure of some small component inside the wing could mean a crash.Again, VERY interesting designs, but you won't be seeing this on a Boeing or Airbus anytime soon. Could have some applications in GA, namely the experimental branches of GA aircraft. I could see this being more applicable to drone aircraft much sooner than with passenger planes. Thanks for compiling the information. Good technology to keep a look-out for in the future.

  297. 2:41 Not 2023, the price is already falling below 100$/kWh for batteries at the pack level for "large vehicles" like buses and, surely, semi-trucks. I guess the 2023 estimation is for passenger cars only. In "small vehicles" one kWh at the battery pack level is more expensive due to the small size of the pack.

  299. Very awesome I would love to see you cover about the uses of Graphene that could be used in radiators for both on earth and space because of it being about 10 times more better than water cooling and 25 times less energy I believe tho I can't remember fullu but I do study a ton of science and stuff from new atlas, business insider, undecided with mat farewell, and more tho I would like you to cover from what I said of graphene that could be used for both on earth and space including maybe other small things and stuff like electronics and things. Thanks for the video, the quality is great, wish your channel was larger in terms of subscribers you deserve it!

  301. So much potential. We need to address the elephant in the room though. Corruption. There's a lot of it in Africa. As there's a lot of minerals in Dr Congo so lot of potential of wealth. But great idea. I hope it works out. ♥️🇨🇩

  307. One thing that I have never heard an explanation is how the energy from a nuclear fusion is extracted onto the grid.
    4
  308. thanks for not dumbing down the science too much. too many videos on fusion seem to be more concerned with selling the idea of fusion rather than get into the gritty details of how fusion reactors actually work.

  312. Just looked at my water bill, I am currently paying 1.54 GBP per 1 cube meter of fresh water for domestic use, which translates to 0.154 pence per liter. Taking currency exchange rate into account, it will be just under 0.2 cent. Which I think is a funny coincidence :)

  322. Their Gen1 is basically as good as a standard Lithium Ion battery in gravimetric, volumetric, and economic energy density, but it seems like they already know ways to improve their system significantly. If they can make gen 2 even half as good as promised, that would be an absolute gamechanger.

  325. Good work kiddo! :) I'm 80 years ion this planet and what I'm REALLY sick of is discount advertising, well, advertising in general. May I suggest a little more enthusiasm in your presentation? You look like a very bright young man, and I'm sure some smiles would help you develop a following. Take care with jokes though that can so very easily fall flat and ruin a great performance. OK, that's my 20% off, :) Cheers and keep it up!

  327. I have an Aptera on order but I'd never say it had infinite range as it would come to a stop after about 400 miles if not charged; and while it is true I may not have to charge it in sunny climes and still drive perhaps a commute modest commute distance that is still a distance of about 30 miles; if I want to go to visit another town after work; I will need to charge up. Anyway; they do have a couple actual cars so they ought to be able to determine actual drive distances.

  329. Ziroth, for a nearly always active boat, 20% fuel saving is an astronomical amount of money. For just 28 days at sea, a large container vessel burns approx 210~ tons of fuel, per day, resulting in a round trip cost of (if fuel is roughly $550/ton) roughly 3.2~3.3 million dollars. Twenty percent of that is 600~700 thousand dollars saved. IN ONE TRIP. These vessels work year round!

  332. Maybe this technology could help tuneling as well. For subways, water distribution channels and so on.

  333. Hi love the vid! But a little more research would be appreciated. Especially in the last part about 'aerofoils'. 'Aerofoils' are actually sails (look at sailboats pls!). You missed a lot of points there! You also attributed the loss in efficiency there to causes that aren't at all the cause of the loss in efficiency there! If you want me to go into more detail then ask me or you can just look some of these things up Btw for the youtube algorithm the video needs to be between 10-15 minutes. But again love the vid! Hope I have given you some constructive (!) feedback! Stef from Belgium (a sailor :) )

  337. Looking at the graph ,New Zealand is in zone 4. Although some parts of the country get more sunshine hours than others,we get good sun even in winter,and plenty of U.V on cloudy days.Given our power supply is 240V should charge in no time.Only question;when will we get the Aptera here? Right hand drive/compliance issues?This vehicle would serve most journeys (for 2).A larger vehicle can be used to carry more people or loads /towing. A price of U.S $25,900 is about $44,500 here.(plus freight?)
    3
  338. From the Aptera FAQ: We will not know Aptera's actual rating until we pass a production vehicle through the full safety test. But we are designing to exceed all passenger car standards and the previous version had the highest roof crush strength of all passenger cars on the road, it performed exceedingly well in actual side and frontal crash tests. Aptera features a Formula One-inspired safety cell with advanced composites and metal structures for impact strength. Similar to aerospace and racing, these energy-absorbing methods are a core part of our safety strategy and have proven effective time and time again in high speed impacts.

  355. ITER is being designed in a way that they can swap out and test lots and lots of designs for heat transfer and fuel breeding. There are a lot of unknowns within the engineering context. These systems all add to the overall knowledge.
    3
  356. Great video! So many people get excited about rooftop wind power, but completely overlook terrain effects (turbulence intensity profile). This design is interesting, but with a fast RPM turbine, vibration effects over time would be a concern too. Still, this design is probably the best attempt I've seen so far!

  361. I'm not sure how your video was recommended to me. I am a technology and green energy fan and watch a lot of educational videos. Your video was well done and sounds like a very promising technology. I've always said that the market and technology will solve the energy and environmental challenges we face. I'm interested to know the microphone you are using to record your narration as I am working on building my own channel. Cheers.

  366. These devices look very promising, but mainly if consitions are met: on big office buildings, and warehouses. There are plenty of these around! Also, they can be comnied with solar panels. I also wonder if a rotation mechanism would make them much more expensive? And are they more efficient when scaled up like traditional wind turbines?

  377. Zinc-Air structural batteries could make electric vehicles 3-30 times more energy dense without adding any weight compared to conventional lithium batteries. Still not quite to jet fuel energy density but overall you can make bigger batteries with less extra weight. But when you consider the ion wind effect was measured by MIT to be up to 55 times more efficient than jet engines, these technologies, structural batteries and the ionic or plasma engine designs, could be combined to actually surpass the performance of jet fuel engines, even using more conservative estimates of the battery and engine performance.

  386. Really interesting video and statistics. An amazing car even if you did have to charge it the distance it travels is insane and I'd use it. I'm in Greater London and it's a bit of a no brainer providing pricing is right. Thanks for your effort. Appreciated! 😊
    3
  387. Really interesting and a great balanced assessment. It seems clear massive turbines work in open windswept places, but we should remain open to research into other micro level applications that might integrate with infrastructure and land in use. As a real estate agent might say, it's about location, location, location. Perhaps on the roof edge of the right apartment or industrial building, or who knows even on a cargo ship, these could offer better energy density, low cost power at point of use when the sun doesn't shine. I can see these working alongside highways with the right prevailing winds, potentially integrated with lighting posts. In Australia where I am they might even produce power for EV charging stations and communities in remote off-grid locations. We even have an EV charging station on a remote highway that runs off used fryer oil from the roadhouse!

  395. A wonderful SCIENTIFIC achievement — Optical Breakeven — from LLNL/NIF but not a very useful result from the TECHNICAL perspective of the topic. Using Nd:Glass lasers with so low conversion efficiencies for electrical energy into optical laser beam energy means you need a thermonuclear output enegy several hundred times higher. There is no other laser types with the suitable frequencies and power stability; the hope we had in the mid 1990s for Semiconductor very high power lasers has never realized. Besides there are a huge number of other overwhelming optical, material, electrical, thermal, even mechanical* engineering issues that have to be solved to get a practical, affordable and profitable Inertial Fusion reactor. There are not enough brainpower employed in these problem anywhere, and ICF funding is mostly provided by the military budget of the DoE, so the predominantly foreign (~2/3) High Energy Density Physics graduating from UoRochester, UCDavis, UCSD, UNevada-Reno are usually excluded from ICF R&D. In the USA, ICF is predominantly a military-oriented program — to research, test, homologate, validate R&D for Thermonuclear and Directed Enegy Weapons — so to avoid traditional Nuclear Testing. Profitable Energy generation is not a priority — results like this ignition are predominantly budgetary PR and PC propaganda for DoE's Lawrence Livermore, Los Alamos and Sandia National Labs. The bad thing about all this brouhaha is that material, financial and BRAINPOWER resources are diverted from better latter Generation (7th? — it was 5th in the mid 2000s) Nuclear FISSION Reactor Technology (including Thorium-232 one) to pursue this Rube Goldberg-like nonsense. * My last job at ICF in UCSD, after getting a Ph.D. in HED Physics at UoR. I got into HED/ICF/Plasmas because I wanted to build Fusion/Plasma propelled Interplanetary Spaceships and retire in Tethys (a moon of Saturn) ...

  399. This seems really advanced and complicated, however you do a great job simplifying it into something more easily digestible. You are a wonderful teacher. I like thinking about this kind of thing. The world is an exciting garden of possibilities. We have tasted some and even integrated some into our regular diet. I think that many wonders yet await! The right set of ideas change the world.

  400. "If we want people to go electric, we need electric vehicles which travel further per charge." Wrong. People in the UK don't want range. If we want people to go electric, we need two things: . cheap EVs such as BYD Dolphin and Seagull, hopefully cheaper in the future by using sodium-ion battery . reliable charging infrastructure, something we lack in the UK, where instead of range anxiety, we have charger anxiety. I also say, let's get people onto trains. For America, where trains and transit don't work, and neither does cycling? Well, it's because America is built totally wrong; read Strong Towns to know what I mean. A little density is more than good for you, and when I say a little density, I don't mean Asian levels of crowding, but something more akin to the Netherlands, Paris, or London.

  404. Do the figures you quote for LCOS only cover the storage or do they include the generation costs of the power that is input into the system? Either way, this all seems like pretty expensive power, to me. $300/MW.h is more than I pay retail. As to the output, it’s horses for courses. At the discharge rate of 0.8C the lipo battery pack will discharge in about an hour and a quarter while, at their lower C ratings, the other two will last for two and a half, and five hours, respectively. So lipo for grid balancing and the others for top up when renewables aren’t producing, perhaps. It would be good, also, to see figures for the carbon cost of energy. What is the carbon footprint per lifetime MW.h of these systems? Concrete is not exactly the most environmentally friendly material to produce. I suspect that a concrete reservoir can hold an order of magnitude or two more water than the mass of the concrete required to build it. All of these technologies are worthy of investigation and will probably be included to greater or lesser degree in the future. To a very large extent, the future of renewables will depend on the development of storage solutions. IMO, distributed storage using mass produced (economies of scale) batteries along the lines of Tesla’s Powerwall is likely to provide the best answer. It will be able to extend the life of EV batteries beyond their suitability for transportation. It will increase the robustness of the grid, reduce the amount of high capacity transmission needed in the system and give individual users protection from grid outages. If I was younger I’d be thinking about setting up a business to repurpose EV batteries for storage. Another few years, and second-hand ones will be flooding the market. Even at only 70% of its original capacity the Tesla Model 3 battery can store over 50 kW.h. This is about 3 winter days worth for me in my small, totally electric house.

  408. Once they release safety information, assuming it's reasonable, I'm getting on the list. Forget the onboard solar panels - you can put 100+ miles in overnight using a standard U.S. 120V 15A outlet. No $1K charging stations. What a great second car. And it's clear from listening to interviews - and from looking at parts - that they are partnering with Tesla for supercharging if one did want to make longer trips. Could be a game changer.

  422. This might be a more practical option once all vehicles are autonomous. This doesn’t look like a very safe car from a crash test perspective. Once we have autonomous cars crash safety will far less of a concern and they can be designed to be lighter and more efficient. Thanks for sharing this story with us.

  426. it reminds me of the transistor industry, how gates are becoming only a few atoms across. we have so thoroughly pushed technology we are reaching the mindbogglingly tiny scales, that short of making our own subatomic machinery, might as well certify us as masters of the universe, at least in a single field. like superconductors, sure, we don't have room temp ones, but the fact literally 0 resistance is even possible is something i thought would be godlike material. in scmaglev trains, they literally dump moving current into them and it just keeps going, practically forever. seriously, like plugging a powerboard into itself. are we not gods yet? it doesn't feel like it, but the materials we use sure are godlike

  440. The more I learn about thermal storage the more it makes sense, after all stars and plants store massive amounts of thermal energy. It almost seems as though this is the energy road we should have been on all along. Imagine improving apon the materials that make T. E. Gs being perfected and then superheating a composite ceramic rod to thousands of degrees and thru the use of metameterials controlling the rate at which the heat is channeled off. Entire power plants could charge thermal rods shortly after sunrise....

  443. As the technology improves and costs come down, FLOW batteries will take over from Lithium as the primary choice for renewable energy storage as they're more durable and don't require exotic/rare materials to make. There may be some presence from niche gravity storage applications, but I don't see it as the leader.

  460. For the wind turbines its a 15% increase in the KWh captured over the course of a year. All of this increase comes not from the top end where the turbine is 85% efficient. It comes from wind regimes where reduced wind speed reduces efficiency of the turbine. So where the turbine is say 65%-75% efficient turbines with this tech would be 80-85% still For aircraft its a 5%-12% decrease in fuel consumption relative to the entire fuel use for a "standard" long haul flight. Although definitions very that is generally going to be flights over 3000 miles. Most of this reduction is coming from the improved airflow over the wing rather than the actuation itself. By removing all the external hardware such as flap track fairings and having no gaps where actuators join to the wing. Secondarily the actuators are lighter than conventional hydraulic or servo electric systems. The reduced weight results in a lower angle of attack and thus less induced drag as is expected for any weight reduction.

  476. Great video. Thank you. I don't know how much people would like the looks of it and I'm not sure how it would fare in crash testing. But if it can offer good safety, it can have a good shot of hitting the roads. Such a would definitely entice those looking at aerodynamic efficiency. It's cd alone is mighty impressive. Edit: I read up and found out that their safety cell is inspired by F1. Would be very interesting to see how this car does once it hits the roads.

  477. As long as you don't crowdfund such project, I think it doesn't hurt to see new innovation. As for practicality, if efficient pedal wind turbine generator can't replace solar generally, how can low efficient but cool-looking products have any chance? Be very careful about such products, it could be a scam.

  478. Punish as in make that combination of parameters undesirable and force the model trainer to predict new parameters that it thinks are more desirable. Punishing a model is just making the model avoid selecting those parameters again in the future.

  496. I agree that this is a very important breakthrough but many more will be needed. We are still many years away from producing a commercially viable fusion power plant. Moreover, it won't necessarily be the Americans who build such a plant first. Keep an eye on the Chinese who excel at engineering. I'm putting my money on them.

  553. It's funny how we look at the efficiency of the whole vehicle as a shootout criteria. (shell in the quoted source.) Tesla had to overcome the same issues with electric vehicles and gasoline vehicles are way less efficient anyways. Most people also forget that hydrogen is or can be a byproduct of Coal and Steelproduction for example and by that can lower the environmental impact of these refineries significantly. We're also making huge progress in storing the hydrogen with metallic frameworks which will eliminate the costs of compression and storage loss. Regarding that Daimler just released a fuel cell with above 80% efficiency I think theres a bright future for hydrogen.

As far as the 110 dB of the Tu-114, I bring you the C-5, which I got to ride back from Europe. it doesn't have the niceties of sound insulation (that weighs a lot), and sounds an awful lot like being trapped inside a giant vacuum cleaner.

  592. Contra-rotating (or "coaxial") props have become a common sight in the drone industry for quite some time now. Also you missed some downsides. 1. You can't just add another prop and the efficiency increases, you also need to install a more powerful engine. If you just install another prop the engine has to work against more drag with the same amount of power which will cancel the added efficiency. 2. if there is enough space, it is even more efficient (about 15-20%) to install the same amount of props side by side instead of coaxial. -> combining these two: since you have to replace motors anyway, installing another set of props in the same plane as the already existing ones gives you an improvement of about 35-40% in efficiency (given your weight stays the same) 3. (drone specific) however for another set of props you need another set of motors, increasing the weight and cancelling the efficiency bonus. So for drones coaxial is only viable if there are very tight space constraints.

I've been making hydrothermally synthesized FeS2 nanocrystals and microcrystals for a while now and have made progress on uniform cubic habit, lattice and even dispersion of solids. I am in phase 2 and 3 simultaneously by experimenting with post transition metals and non-metal element dopants along with additional control parameters to further control growth conditions during phase gradient deposition. We'll see how it works out eventually. Hope it works, but failing is learning during R&D.

  621. OK, so you've got the plasma contained by super-cooled magnets that have to be reasonably close to the plasma, but to run steam turbines you need to extract a huge amount of heat to boil water to drive the turbines. So how are the magnets to be kept cool, whilst all this heat is coming of the fusing plasma ? Bear in mind this heat extraction has to be continuous for weeks, even months at a time. Fission reactors use the reactor coolant, British gas-cooled reactors with carbon dioxide gas and American and others by water. Both pass this coolant through heat exchangers that are the actual boilers that produce the steam. So what is the equivalent process in the tokamac. I have yet to see anything that proposes how this heat extraction on the scale needed, is done.

  622. They keep saying 30 years away to mock the topic but it kinda pisses me off that they doubt out generations ingenuity. Just focus on hosting wars.

  623. Why fold the smaller props away? Use some of them as turbines to charge and what you lose in drag you hopefully gain in flight time

  628. So the warm saltier water goes down the same pipe as the cooler less salty ocean water it the reservoir goes up? Does the reservoir also let the saltier water go back to the sea?

  632. Maybe we could use a COLEX plant built with technology that benefits from SIXTY YEARS advancement. The "we can't do it because of Y 12" isn't far off "nuclear power is dangerous because Chernobyl "

  634. Rondo delivers heat to the customer for use in industrial processes - so it is never turned back into electricity. Companies today are creating heat using gas boilers and this is a zero carbon replacement.

  641. First - thank you to this channel and to YouTube for not handing me more clickbait redigested content recommendations for a change. Second, I love the science, and it's important science. But... in the real world, well I guess if you love your monopolistic coal and fission powered utility with big expensive centralized generation facilities... I guess you're just going to be absolutely smitten by your monopolistic utility with big expensive centralized fusion generation facilities.

  650. In addressing "why flames glow," adding: "electrons bounce" and or in the state of electrets ("becoming photons" state) radiate. Does it sound like a hit song? The same might actually in consistency with the above reference to "bouncing to limit (LIM) bounds" be: the model of "Q-scale." As the micro to nano PERCEPTION of timed radiant patterns of "bouncing within their energetic bound limits." Within the well and being of their stability per atomic structure expressing it's own individual perspective. This description having been one of the primary points of Mark McCutcheon upon the foundation of "The Final Theory" (2004).

  654. I was going into this thinking, "Yeah, another BS vaporware green-tech start-up looking for suckers." Gotta say, this all seems completely feasible. It's far better to use excess energy generation rather than fuel to heat and save the fuels for applications where energy density and power on demand makes renewables and batteries problematic. Calling the cooled outer insulation shell "dynamic insulation" is a bit of marketing that's annoying but the concept is a logical way to preheat the incoming air. Like the guy said, they aren't based on any novel invention. Most of what I seen here was honestly stuff that a clever undergrad could come up with. I say that not as a criticism. It makes this far more convincing that it doesn't rely on any sort of convoluted or proprietary tech to work. I'm sure they'll have proprietary tech to increase efficiency, increase energry density, etc. but that's just refinements on what is a seemingly simple yet effective idea.

  658. In the middle of the video, I pause it, exit the fullscreen mode and I see how much subscribers you have! Ryan, this is a new channel with quality content and the topic - the new Era in Energy production and zero-carbon future is so vast that need much more publicity like yours! The whole Energy sector worldwide is for Trillions of dollars every year and I seriously think - how we can find financing support for a really information Quality platform, a web site with videos and news all related to the topic. A project like this will be so useful for college and university students, young entrepreneur, environmentalists, engineers, local green communities all around the world and even can be inspiration for some engineers that can invent or improve something in the sector. An online resource like this, curated, without any bias that can offer really clear point of view no matter the technology and achievements are from US, Russia, China or Sudan. We live in so important times and actually, we decided the future of the Civilisation and the Planet right now and more awareness and information that come to everyone is more chance to prevent the point of no return with the Eart climate and the Global warming. Some $10k per month can provide and cover expenses for few people working on the topic and produced Really quality content and these $10k are just Nothing in comparison with the Trillions of the whole industry and consumption. These ideas and achievements, all these news need to reach as many people as possible for the good of society! Think in this direction Ryan and not something like a monetization from ads and Patreon, but on some financial program on a national or even global level, because the topic is important for everyone. If you need technical help for web development write me back and I wish you success! :)

  668. Probably a dumb question, but would this make them any lighter at all? Could possibly have increased range for vehicles or open up more doors for electric planes.

  670. Another positive feature is that it is less likely to mince birds - my greatest objection to conventional turbines. They are less ugly.

  671. what, so, only the highly specialised terroir of the Orkney Islands creates hydrogen spicy enough for this roller jet engine? or would blue and red hydrogen work just as well?

  684. How does a 47 kWh battery power 246 kW of motors long enough to travel 100 miles @ 175 mph? They must spend a lot of time throttled down.
