This is how Water Engines Work!

Look, this is a dead duck. Terrible end to end efficiency, obsolete heat engine technology that's complex and doesn't last long. BEVs are the future, not this nonsense.

I'm in the field. This video is absolutely b*llshit.

ehem... mirai anyone? hehe ahh... yeah nah ..

I have the suspect that this whole text is AI made. No exact data, no real efficiency values, nothing.
To make a summary, hydrogen power is not water fuel. To make hydrogen from water and burn it in a fuel cell is much less efficient than simply store the electric energy in batteries and use it in electric vehicles.
More dangerous, more expensive, more complicated and vehicle range also falls behind ev-s.

May the future will bring a breakthrough in hydrogen production efficiency, but at the moment it is a dead end.

AI will be the death to accountability of the internet.

And, did I see a combustion engine in the video? 😆

Will the engine rust😢

You skipped very quickly over the production costs of the hydrogen fuel, money and CO2 and the dangers of fire. You say it is using better "technology" which is totally meaningless, bullshit speak. So here is my take on why Toyota are doing this, it is all about timing. They know EVs are doomed and will be gone in 2 years and any investment will be money down the drain, big money, they have seen the huge losses and bankruptcies.. So they mess around will this bullshit for a couple of years, throwing a few Yen into it and then ditch it.

The only thing is nobody can start it. That’s why everybody doesn’t have one big deal like if anybody could start a water Engine we’d all have one. There is no such thing except in dreamland, but then after approximately eight hours, we wake up.
