Foot-Powered Laptop

Apparently 5 minutes of brisk pumping will give you 20 minutes of battery life, it can also be used to power most other electrical devices with a rechargable battery."

    This would be kind of neat for when I work out. I run on the treadmill first for 30-40 minutes. It'd be cool if that time recharged my mp3 player....

    "The StepCharger weighs 10.5 ounces and is roughly the size of a paperback book; it can be used to charge anything from satellite phones to digital cameras and video cameras, as well as laptops. "

    I was just thinking such a device could possible adapted to fit on the bottom of your shoes. That way the activity of walking or running could be used to generate power instead of pumping standing still. Man, I must have hit a nerve with someone who's chips and dip ran out or something.
