Because hydrogen is not a fuel. Because hydrogen needs heavy containment
vessels. Because petrol, alcohol and diesel oil are all better fuels.

**** but you're thick.
Hydrogen is not a fuel??????????????

Correct. Hydrogen is not a fuel.

And which obscure dictionary did you read to come up with that theory?

Unlike you I don't rely on ****poor dictionary definitions.

It might not be a primary fuel, but the Yanks in the 1960s thought it
and oxygen made a darn good fuel for shoving a rocket into orbit.

Hydrogen is a fuel in the same way that a battery is a fuel. You get
less out than you put in. If you need an incredibly large specific
impulse for a given weight you may well think that the losses are worth
the conversion. However unless you are powering a rocket or a SABRE
engine all you are doing is ****ing fuel up against the wall in order to
create hydrogen.

A battery is a fuel too. It is chemical energy. It converts chemical
energy to electricity.
Energy can't be created or destroyed, just converted from one form to
another.
And it can be spread/dissipated.

You should have paid more attention at school.
