I can’t wait to drive around in a Hindenberg. Except it would be pressurized, so actually it would be more volatile and have greater explosive power. Oh and instead of floating relatively slowly in the large, voidlike arena of airspace, I would be hurtling down narrow corridors with hundreds of other large metal objects, many driven by idots, going in other directions.
I’m not so sure as to the viability of hydrogen, at least in cars. They crash too much.
