Activ - Personal Electricity Generator by Ben Azzam » Yanko Design

This is a cool idea. Especially if you jog or are walking around a lot during the day. You'd probably never need to plug in your cell phone or what have you.

This clever gadget, called Activ, makes it possible to harness the kinetic energy created by your own body! The personal electricity generator was designed to be worn on the knee- with each step, it juices up the battery a little more. After it’s full, just attach a USB cord directly to Activ to power your cell phone or other device. Instead of plugging into the wall… plug into you!
