You are wrong ....hot combustion burns holes in pistons and melts gas
turbine.
Plus you look at the actual burn time on the stroke .And it is mostly
expansion.
Not a flame 100% of the stroke.Like it or not air expands when heated.
Like it or not the combustion components are at most 20% of volume in gas
engines.
And diesels and gas turbines it is even less.....as little as 0.5% in a
diesel at idle.
The reason you run oxidizers to up that number.Assuming you don't hydro or
melt the
engine first.

depends on who you know.

If you want.

So the answer is no.

Wow. Truly free energy. Oops, air doesn't have energy.
