Have you heard of the second law of thermodynamics?
There's also lots of all-you-can-eat heat in any piece of matter, eg sea water or rock. But that doesn't mean you can get at it for anything useful, without a heat differential (or a pressure differential).

Hum, I wonder where we could find a heat differential and a pressure differential in this planet... if we except the ocean, and the land, and the atmosphere, and any place with an organism able to fart...
