Do you know what a calorie is?

It is enough energy to heat a litre of water by 1 centigrade.

Bit more to it than that: http://en.wikipedia.org/wiki/Kilocalorie

If I'm not mistaken, we actually eat like 2 million calories in a day.

Yeah, you got me. I didn't capitalize Calories. It was late, and I have a tough time playing O/8 and capitalizing at the same time.

its wrong in the sense that nobody can put out 300W of physical force over really any period of time.

Probably, but it can't be that far off. Heck it's less than one-half horsepower, right? [img]/images/graemlins/wink.gif[/img]

I just made some rough calculations assuming an areobic scope of 13, metabolic efficiency of 50% (okay, just glucose), ATP-to-mechanical energy of 50%, and generator efficiency of 75%. No doubt I missed something, but I haven't taken the time to locate my notes from comparative physiology last fall.

C'mon. Someone do the math on lance armstrong.

He uses a simple machine to do a shitload of work. (work in the physics sense)
