Power From the People!

This website sells plans for a Pedal Powered Generator. Basically it's a stationary bicycle that generates electricity that can be used to power "LED lights, the monitor on my computer, my cell phones, and many other small battery-powered things". As he puts it,

"It is the most inspiring workout you can imagine."

The plans cost $50 and it costs another $230 to build the thing. It's going to be a great project for us after we move to Camelot next year. I want to make a conscious effort with my family to reduce our energy consumption by using super-energy-efficient appliances. And then supplement our grid-usage by renewable sources - including this generator (which will also get us regular exercise!)
