  1. there is difference between pumping a liquid and pumping smallest gaseous element in the universe.

  2. Liquid hydrogen isint an option for regular passenger cars, you can't magically keep that hydrogen under -252C temperatures for any extended periods of time, this video was about hydrogen in a gas form, just like every single hydrogen car in the world uses.

  3. Will simplify things here: you need 2kg of hydrogen to make 1kg of hydrogen, and these numbers are not backwards. You might notice potential issue with your idea here.

  4. And what would be the cost of it? How fast can you extract hydrogen from it? How much power you need to extract it? And so on.

  5. No actual mass produced hydrogen cars will be combustion type ones, so you are right, it's all bollocks from the start...

  6. Infrastructure required for hydrogen production and storage costs crap tone of money. When it comes to EV's is allot simpler, but even then its really slow in being adopted. At some point when ICE cars gets completely axed hydrogen cars for public transportation or specific use cars could rise up, but its hardly will ever win over EV's.

  7. Few basic facts here. First hydrogen combustion engine invented in 1806, fuel cell in 1969, so this tech isn't new, its ancient. Second, while it takes to charge BEV's tiny bit longer, that tiny amount is worthless when you consider the fact that you will be paying like 10x more for hydrogen refueling just to save extra 10 minutes, and yes, 10 minutes, as you can go from 20% to 80% on BEV in like 15 minutes, while it takes around 5 to refuel hydrogen car. So that 10 saving is actually you wasting your money. Next, hydrogen needs to be produced, by using electricity, and using more of it, so your complain about BEV's shifting pollution to power plants is even worse complain for hydrogen. Lithium production isn't big issue and we have quite few new battery technologies which either lowers lithium usage or removes it entirely, on top of this, you can recycle old batteries and reuse that same lithium to make new batteries, over and over again.

  8. You have seen AI auto generated scam video. Such system can't existing without breaking laws of physics, aka it can't exist.

  9. ?... How the hell you missed the point of you using 12V battery here?... You are putting in more energy into that entire system than you are getting back out, so you are just wasting energy by using electricity to create hydrogen and then use that for power... Welcome to physics 101.
    1
  10. Because you don't like it?

  11. So you believe it because dude said so? You do know that it never was confirmed to be true to begin with. Right?
    1
  12. Isn't it's interesting that you talking about batteries under video which talks about hydrogen cars?
    1
  13. Because laws of physics prevents this from happening...

  14.  @DamodarDasKirtan  First law of thermodynamics. Will make it extremely simple for you here. You need 2kg of hydrogen to make 1kg of hydrogen. And no, those numbers are not backwards. You should see potential issue with your idea here.

  15. Yea, what could go wrong by having poisonous gas in your car tank... Biofuels are expensive and have high energy requirements to be produced, so its not a good replacement if you want something what is more carbon friendly. And its not carbon negative, there is no such thing in general. At best you could collect back most of the carbon to create new fuel, but to create it you will need to use energy which will produce carbon which you can't utilize as you already used the one which was already created from previous biofuel cycle... All those carbon negative things only apply to tiny portion of entire cycle, not entirety of it. Carbon doesn't disappear when you create biofuel, all that same carbon will be released back into air. Do some basic research here.

  16.  @Mentaculus42  Carbon negative would imply that you are actually consuming carbon during which process you either convert carbon molecules to something else, aka bonding/splitting it, or you, well, bond it and store it as solid somewhere. How exactly would that work with biofuel? As while you can bond carbon with hydrogen creating biofuel, at the moment you start using that fuel you will be releasing the same carbon back into air, so you are not getting net negative here, you simply can't. On top of this you need to use energy to actually bond that carbon to hydrogen, not even talking that you need energy to produce hydrogen in the first place, and each energy source will have its own carbon footprint. " is scientifically determined to be substantially CARBON NEGATIVE due to not allowing the methane to enter the atmosphere directly" Which is weirdly sounding fluff without actual meaning. It's like saying that BEV's are carbon negative because by using electric cars you are not using ICE ones... Or that having solar panels is carbon negative because you are not burning coal... That's not how carbon footprint is actually calculated. "Ammonia is toxic, not poisonous" Exposure to high concentrations of ammonia in air causes immediate burning of the eyes, nose, throat and respiratory tract and can result in blindness, lung damage or death. I mean, ok, its toxic which can kill you if you inhale it in higher doses... I stand corrected... Its not poisonous in that sense... Potato potahto. "It doesn’t surprise me that the non-informed public lack basic understanding." Correct, this is why general public still thinks that going with hydrogen or ammonia or biofuel is better option than just going with electric cars. Go figure.

  17. ... There is no such thing as cars running on water... You will put in crap tone of energy into conversion and you will get back like 50% of it... So if you already have energy to be used for conversion, then why the hell not simply use that to move your car?
    1
  18.  @dianaw4827  Give me link to peer reviewed scientific paper which talks about this magical extremely high efficiency electrolysis... Facebook posts doesn't count. I will wait.

  19. Gas could be free, heck, government could be paying for you to use gas, still would not change anything here... We are transitioning from gas not because its expensive, but because some of us trying to stop killing this planet.

  20. You should actually fact check and not blindly believe random videos on youtube, especially the ones using AI voice with random clips in it. To put it simply, NO, Toyota didn't invented water engine...

  21. 10k is already more than anyone would want, pushing it further would only require a lot stronger tanks with better and more expensive materials while increasing risk of major failures if something goes wrong. Increasing pressure isn't really an option

  22. Magic isn't real...

  23. Stanley Meyer was a scammer... You can't beat first law of thermodynamics. Will make it really clear here. To make 1000g of hydrogen you need 2000g of hydrogen. Yes, you need more hydrogen to create half of it again. Hydrolysis requires a lot of electricity, then you have general energy loses for electrolysis and for hydrogen fuel cell engines which creates huge net loss, aka it's NOT possible to create hydrogen on board without having dedicated battery for that purpose only which defeats entire point of hydrogen car.

  24. Due to basic laws of physics you can't just convert water into hydrogen and then back into water while producing net gain of electricity during that process.

  25.  @hydrogen-power-gas  When you see someone saying "hydrogen on demand" its 100% scam... You can't beat first law of thermodynamics... Will make it simple, you need 2000g of hydrogen to produce 1000g of hydrogen. Do you see TINY issue with those numbers? Water isn't fuel, hydrogen is, but to make hydrogen you need to input crap ton of energy and you will get back only portion of it, aka its a net negative energy, so you simply CAN'T have hydrogen on demand and never will. So congrats, you got scammed, just hoping that you didn't invested in one of those "companies"...

  26.  @hydrogen-power-gas  There is no such thing as hydrogen on demand.

  27. Do you expect to go there on v8 engine or something?
    1
  28.  @OrionDworkinORION  0 to 60 (not 100) in 2.5 seconds is just a by product of how BEV's work, tho honestly HFC cars should be able to do same exact thing as those usually have batteries inside to equalize discharging. And saying that China is doing China stuff doesn't make actual argument against BEV's, it only points out how badly China handles BEV market, nothing more.

  29. Promoting fake videos?... Is someone paying you for this or are you just random internet bot?

  30.  @MrI8igmac  1 gallon? You measure gas production rate in volume?... You do understand that I could go to biggest vacuum chamber in the world and will it entirely with my single fart? Gas needs to be measured in weight, not volume... And no, you can't have diesel generator to create hydrogen, that makes no sense... You will be wasting energy for no reason.

  31. If you want cool v8 noise, go play racing game or something.

  32. Now calculate how much water vapor you would produce from hydrogen car which would actually become vapor and not simply absorbed by ground vs how much Co2
    1
  33. What would be the weight of that tank? What would be the cost? What would be the raw weight of hydrogen you could store in that tank?... Just saying "hydrate" will not make it best option ever by default

  34. Issue is that when it comes to Tesla startup, they had no actual competitors, but lucid now has Tesla. Like this car is 2-3x more expensive than Tesla model S Plaid. It's not that compelling to buy lucid when you can get multiple Teslas with tiny bit less performance in them. Lucid is struggling and burning money at the moment, this is why they want to have ridiculous cars like this one, just to remain on the map.

  35. Cool beans, where is this technology? How much energy do you need to free it? What would be the cost? What would be the weight? What is the density number? I keep seeing claims like yours, but non of you manages to present actual numbers...

  36. They are just idiots. To be more serious, when car company boasts about making some super duper clean car, its usually just PR move to tick that box "making green cars" and that's that.

  37. Irony is strong with people like you. In what form hydrogen (you said nitrogen) should be for it to take less space? Liquid... It should be liquid... And how can you make hydrogen liquid? Chill it. How low you ask? -250C and colder. Its cold, really cold. Now. Can you even grasp basic idea of what type of container you would need to keep that hydrogen chill at such extreme temperatures for long periods of times? You can't, it would boil off in like 3 days. So liquid hydrogen isn't being used in any passenger cars for this reason. So, as we put this aside, what else you will have? Hydrogen in gas form. So how much space would hydrogen in gas form and under something like 10000 psi would take to achieve 300 miles? Its more than regular gasoline tank.
    1
  38. Because you will need to put MORE energy in separating that hydrogen from oxygen than you will get back out of it, aka you will lose energy, aka water isn't a fuel, never was and never will be.

  39. Reality disagrees.

  40. Did you just tried to measure gas in volume?...
    1
  41. Liquid hydrogen usually boils off in few days, not much you can do about it

  42. This doesn't exist... Fact check next time.

  43. Ammonia is toxic and extremely corrosive across the board. Duno about you but this isn't a good solution even if it was a free fuel.

  44. Hydrogen could only worked if we got those before BEV's went into mass production, so when we already have better alternatives, why would anyone want to go with hydrogen?
    1
  45. Ok.
    1
  46. From where did you got this magical number? And have you seen hydrogen cars? Those with 3 huge tanks and getting 400 mile range? So then, what range do you think you could get from your retrofitted car? 100 miles?
    1
  47.  @gjermundification  You are missing one TINY issue here... Your calculations are based on Hydrogen being in a liquid form which is extremely difficult thing to have and quite impractical in general as it will boil off by simply being in your tank. On top of this. You will need actual place to put this new tank or multiple of them, so existing fuel tank place will not be suitable for it, so most likely your trunk will be used, so you will lose that one entirely. This assuming that you could go with liquid hydrogen. If not, then you will have tiny range by going with highly pressurized hydrogen tank. Its not that easy to just convert existing car... It will cost you arm and leg to retro fit it, then it will be extremely inconvenient due to how much extra space it will take and then you will pay arm and leg to refuel it... So why would anyone want to do it?

  48.  @gjermundification  yes yes yes, just get bunch of cinnamon and you can travel across the world...

  49. First of all, water isn't free. Second, you can't beat basic laws of physics here. You could have easily said that your legs are free so now you will just walk everywhere for free... Well... Those are not free either
    1
  50. You could, issue is when you are not using that car, and boiling off isn't really adjustable on the fly, so you still need a method to supply hydrogen in quantities you actually need at that moment.
