Sorry Dave - I'm interested in what's said more than who's saying it.


No, it's not the heat which makes the power, it's the thrust generated
by the expanding gas. The heat is a byproduct.
Your understanding of internal combustion engines is flawed.


You're saying that expanding gases make the piston move, but that isn't due to heat?
