Hearted Youtube comments on Ziroth (@ZirothTech) channel.

  1. More of these deep dive detailed engineering topics please. The more challenging the better.

  2. 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.

  3. 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.

  4. 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 : )

  5. 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...

  6. If I could buy stocks on a YouTubers potential growth rate I would sell all my Tesla and Apple and buy in on you

  7. 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
  8. Pretty amazing content for such a young channel, subbed for sure!

  9. They definitely need to tweak the flux capacitor.

  10. 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!❤

  11. 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.

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

  13. ​ @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.

  14. 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
  15. 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
  16. 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

  17. 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.

  18. 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.

  19.  @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!

  20. They should use this with a high voltage wire when training on the tether, would save a load of fuel and emissions.

  21. This is the kind of ingenuity needed for solving energy storage! Great video, and thanks for sharing!

  22. 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. You're seriously stepping up the editing game!
    23
  24. Cheeky face reveal ;)

  25. 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/

  26. 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
  27. It was more theoretical while I expected for real projects or prototype as in thumbnail.. Overall great explanation! Keep it up 🤘
    22
  28. Really interesting, please keep covering such topics.
    21
  29. 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
  30. 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
  31. 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

  32. 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.

  33. He wasn’t joking when it literally appears everywhere. Wonderful video ziroth

  34. Massive thumbs up for you beer analogy and I've even subscribed to you. Nice work on your content

  35. 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! :)

  36. 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.

  37. 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.

  38. 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

  39. 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?

  40. 1,800 hp, should be enough to get to the supermarket

  41. 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
  42. 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
  43. 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
  44. FYI: Alaska Airlines is NOT a "regional" airline. It flies internationally. Not a complaint, just a correction.
    18
  45. Cool video, but it could be longer and more in depth. I feel there were some better ones. Keep it up!
    18
  46. Loving the history/mythology crossover/backstory. Another great video!

  47. 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.

  48.  John Jack  lmao. Imagine being the ordinary bloke from UK who runs this channel reading that people think he's with the CCP.

  49. 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."

  50. Carrying material in the air before depositing it on the structure costs a lot more energy than a crane or a giant printer no ?
