Hey, I just read my own post. Sorry if I sounded a bit grumpy Magik. I havn't had my coffee yet.

Almost any reaction that oxidizes produces lots of heat as a by product. Excess heat is of course wasted energy. Oxidation is the primary reaction used for energy by our bodies, civilization, and life on the planet in general, isn't it? When you say inefficient, what are you comparing to?
