Aye the battery blinded are all flying out of the woodwork now it looks like the game is finally up for Lithium - its gone as far as it will go, small to medium ground applications.

It's ridiculous anybody was ever convinced lithium would power large passenger aircraft, absolutely ludicrous. Shame if you were one of the ones hoodwinked.

I showed how to see the fundamental physical limit of it, so now attention will move to hydrogen.

You think airbus or boeing couldnt knock up a hydrogen plane almost instantly when funding moves to it? Get real. 500Wh/kg is nowhere near close to what you need.

Multiply what you really have, less than 300Whr per kg, by 100 and then you would be getting close to what we really have with hydrogen.

There is 33KWhrs in a kg of hydrogen, 39 if its used in an ICE engine like Rolls Royce already tested, many times, many different engines.

As for efficiency, who cares, if every kg of hydrogen produced, when produced from solar, removes 33KWhrs from the energy of the sun, which comes for free per Joule, but if not used ends up as heating the planet? Do you think it doesn’t do that?

Go ahead and try to show that is not the truth. We could do with some more laughs.
