Cool ideas: 12 @ 10¢

You know what somebody ought to invent? A commuter train (or, better yet, bus) with a gym in it. Get on, work out, take a shower, get off at work.

You know what else somebody ought to invent? A way to recapture the energy people put out while working out. That way, the commuter bus could run on human effort instead of gasoline!

And maybe then somebody could install an energy-capture elliptical machine in my living room, and tell me I couldn't use the computer till I'd generated enough energy to run it.
