>Not really, air isn't explosive (to differ from "explosive P" (*)). It would be a mess, of course, but I don't think this is in any way more dangerous than driving a tank full of gasoline vapors on a hot day, or a bottle of propane (that thousands of vehicles in Europe use regularly instead of gasoline) or a similar bottle of hydrogen - which are all combustible and explosive.

I was thinking that to get propulsion from compressed air aot combustible gas it would need to be at a hell of a pressure to get any kind of range out of the vehicle. If you rupture a compressed air vessel then I'm sure you'd get the equiv. of an explosion.

What is "explosive P" ?
