Renewable Resources...?

So on my my way back from Sonora to the beautiful Santa Cruz this weekend I drove by foothills filled with windmills. Do you know what I am talking about? It's like an alien planet, hills of white statues spinning in sync as the wind blows. Anyways, it got me thinking. There is so much potential, unused energy just sitting around. We could be using the wind, the flow of water down rivers, the sun... And that's when it hit me. Fat! We are the most obese country in the world. We should come together and make good on that blubber. Here's how it would work. Much like wind mills make energy from the kinetic energy of wind, we could turn gyms into power centers. As we run and break down the extra pounds, the treadmills could be harnessing that kinetic energy and our PG&E bills would shrink, hopefully along with our waists! I am a genius, I know.
