[arantius]

I used to think along these lines. But in actuality, not so much. By this definition they're the same thing. An electric motor converts electric energy into kinetic energy. A gasoline engine converts chemical energy to kinetic energy (and even more waste heat than the electric motor). (Neither of them produces power, this is of course impossible. Unless you're subtly using a very specific technical meaning of the word?) This input/output difference is a minor distinction.

Or in other words: the power that a gasoline engine uses wasn't produced in the engine, it was produced by geological and chemical means, and in a giant refinery somewhere else.
