This clever gadget, called Activ, makes it possible to harness the kinetic energy created by your own body and transform it into electricity! 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. And you become your own power plant. Designer: Ben Azzam
