Comments by "TheThirdMan" (@thethirdman225) on "The Unfortunate Truth About Toyota's Hydrogen V8 Engine" video.
One slip and it’s, ‘Oh, the humanity’ all over again.

Hydrogen doesn’t contain enough energy per unit volume to make this work.

@robertburau1520 No, big oil are paying to stop EVs. Hydrogen is their next major project.

Sabine Hossenfelder did a video on this too. It’s called something like, ‘Why Hydrogen won’t save us’ or something like that. I think Jason has done a slightly better job of explaining the problem though.

@nobodyimportant7804 They are all problems. The more I look at this, the more I think this engine is a hoax. I just cannot see how it could develop the power claimed for it. The pictures of it look like bad Photoshop too.
2
@nobodyimportant7804 I think it exists too but I’m not convinced that ‘it does what it says on the tin’.
2
@nobodyimportant7804 I still think it’s an engineering dead end so my thinking is that they never will prove it. But even if they prove me wrong, there are still formidable infrastructure problems which would have to be overcome before it could become a reality.

So well explained, Jason. Well done.

@dr_jaymz No, that was mainly coal gas.

@serjonunes181 😂

If I may, I don’t believe it will get that far. This is an engineering dead end.

@tangowoodworks7332 I’m not sure why they did this. As one who has links with aviation, I can attest to the fact that land tugs, which are invariably Diesel, run on things like Avtur (AKA: Jet A1). So there are lots of fuel options for Diesel engines which are not really exploited by companies like JCB. I’m not saying they’re wrong - though it’s pretty clear what I think of hydrogen - but I don’t know what the thinking is behind the decision. It’s interesting.

@jla6558 I think that’s already being done.

@jla6558 I wasn’t aware either, though I knew they were switching to it. Running forklifts indoors the only other option is electric and that works very well.

@Aizemiyo Oil industry propaganda.

@saltymonke3682 No you can’t.

@saltymonke3682 Lithium is recyclable. In ten years, over 80% of the lithium in EV batteries will be recycled.

@saltymonke3682 Do you know how much electricity you would need to do that and what the carbon cost is relative to density? I’ve seen people doing this and claim to have it solved. But watch the videos and see how long a tank of hydrogen lasts running a typical American V8. It barely lasts to the end of the video.😂 Meanwhile, I have a cousin who lives in a remote community and just bought a Tesla. He has a roof full of solar panels so trickle charging it will cost nothing (the house was built before Tesla started manufacturing on the present scale). Added to that is the fact that the car has no maintenance schedule. The only costs are consumables. This hydrogen engine is a hoax. Oh sure, it exists but it’s going nowhere. It’s a publicity stunt to keep the holdouts (duped by oil industry propaganda and a healthy dose of denial) on side. Even the photographs are suspect. They just look like bad Photoshop. The engine appears to have exhaust ports on both sides of the head and no intake ports!😂 And again, lithium can be recycled and it will be.

@saltymonke3682 Haha! I love how you oil industry sock puppets think range anxiety is some sort of killer argument. I told you: my cousin lives in a remote community. He’s done the homework on it and it works for him. In fact, the range of a Tesla, in normal use is little different from most other cars. While it takes longer to charge, you can do it at home. Trickle charging off solar panels means the battery will usually be full. Try doing that with an ICE. You can’t. You can’t do it with hydrogen either. The point if this video, just in case you missed it, is that with a normal size tank of fuel, this engine will have a range of about 80kms. Think about that before you call me dimwit.😂 I don’t own an EV but I do drive a hybrid. I will be exchanging it for an EV as soon as it becomes feasible. Right now the place I live in won’t support it because I live in an apartment block.

@saltymonke3682 "here's no electricity cost because wind power itself can't store their energy on peak power and low demand, that's Hydrogen is for." Pffft. You could use the same energy to charge batteries more effectively. Hydrogen is far more dependent on electricity than batteries, including the production stage (of batteries). Sabine Hossenfelder has done a video on this called 'Hydrogen will not save us. Here's why'. She explains the physics behind it (she's a physicist). "It's literally unreasonable to have battery to propel cargo ships because as I've said, the energy density per kg is not there, and won't be there because it's basic physics." You're bluffing. I don't recall mentioning shipping in the context of this discussion. As far as I remember, this was about a much promoted V8 engine that runs on hydrogen. From this we know that the claims made for it are suspicious and may not even have been established in testing. Given the amount of hydrogen needed to produce that kind of power, I reckon it's BS. I'm sure they built an engine but the photos look like bad PhotoShop and the power levels are not believable. Incidentally, this engine is basically only being promoted in the United States, as far as I can tell. You've been lied to. Don't expect me to believe it just because you do.

@saltymonke3682 "Yeah, her assumption was an old assumption that you're using cryogenic tank to store hydrogen, while today's tech, you can use compressed hydrogen and LOHCs" Yeah, well, even practical types have to learn theory. Besides, I don't see that it make a whole lot of difference. There's no way you're going to get the same amount of energy from a litre of hydrogen as you will out of a litre of petrol. "because she's just a teacher not practical engineer with practical knowledge like us." You're not full of yourself at all, are you? "More electricity dependant? Like those BEVs? Hahahahaha.... You can't even store power efficiently and recharge it if it's too cold and you need extra power to heat it up. Basic thermoelectric" Different issue. You're still going to need about five times the electricity to extract and story hydrogen as you would to charge a battery. In relative terms, batteries make a lot more sense. Almost all the energy goes into the battery. And the new ones can charge to 100% every time with no effect on their lifespan. And have you checked how quickly those batteries can deliver power? They'd wipe the floor with this piece of fiction.

@saltymonke3682 "More electricity dependant? Like those BEVs? Hahahahaha.... You can't even store power efficiently and recharge it if it's too cold and you need extra power to heat it up. Basic thermoelectric" So what? Have you seen how fast a Tesla accelerates? Do you think that happens by accident? No. Electric motors are vastly more efficient than any reciprocating design, have only one moving part and deliver maximum torque from zero. "That's why Porsche is making synthetic fuel rather than battery because the scope of usage is far greater than battery. Oh, and charging time, how long your battery vehicle needs to be recharged vs V8 gasoline or ethanol? Yeah, it matters." More oil industry propaganda. Try filling your hydrogen car at home. You claim it can be done but you couldn't do it without three phase power because the demand would be so high. All you need to charge a Tesla off grid is solar panels and a storage battery. Easy. We weren't even talking about petrol or ethanol. You keep dragging up irrelevancies. Try to keep up.

@saltymonke3682 "Just ask her how do you want to save the world with batteries for ships, heavy equipment, aircraft and even long haul vehicles." Again, another red herring. You can't have much of supporting argument for hydrogen if everything you say is just bashing things we weren't even talking about. Who mentioned ship? Nobody. Try to keep up.

@saltymonke3682 This thing about batteries degrading ‘fast’ is oil industry propaganda again. I have been monitoring this myself and it’s not true, at least not in the terms you’re putting forward. The batteries used in a Toyota hybrid have been around for about 30 years now. Engineers have tested 20 year old batteries and found they were within a couple of percent of a new one. And remember, unlike an ICE vehicle, the EV doesn’t have a regular maintenance schedule. In other words, the only things you need to worry about are consumables, like tyres, brake pads and windscreen wipers.
