I think that's the smartest thing I've ever seen Dude say. It actually makes some sense. Well the treadmill part anyway. And while TD is right that you really couldn't work out enough to make any sort of profit, and you also wouldn't be able to work out enough to power anything more than like a lamp.. but it'd be pretty sweet if the time you spent on a treadmill contributed to some Green effort. Gyms could get some benefit from it, maybe.
I got really into working out this year....
