Carnot’s big ideaA reversible engine works as well backwards as forwards . . .
So no engine operating between two thermal reservoirs can have more efficiency than a reversible engine between the same reservoirs, and all reversible engines will have the same efficiency.

Why gasoline?
“Gasoline stinks. It pollutes the atmosphere with carbon dioxide, and it is blamed for global warming and for nitrous oxides that cause smog. It finances totalitarian dictatorships and terrorists and drives us to war.”
