Human Powered Generators

It's summer right now but once winter comes along, many of us cyclists will be stuck back indoors on the trainer. Here's a way to do something with all of that energy your expending! You'd need three or four Lance Armstrongs to power your entire home but you could certainly make some good use of the power generated by pedaling. Maybe power that fan that you have blowing on you during tough trainer sessions? I think I may give it a try to charge my iBook. Pretty easy to build your own, but commercially produced versions are available at www.windstreampower.com.
