Power Walking, Literally

by Txchnologist Staff

Rice University mechanical engineering students have built a prototype shoe fitting that generates enough energy to power portable electronics and recharge batteries.

The fitting, called PediPower, diverts the energy of heel strikes while walking, which would otherwise be lost into the ground, through a small gear system and generator. In bench tests, it delivered an average 400 milliwatts, enough to charge a battery or operate a cell phone. Their creation joins another body-powered generator developed by U.S. and Canadian scientists—a knee brace that can recharge up to 10 cell phones at once.

The Rice seniors hope their innovation will be improved upon by the next group taking it up to boost power output and decrease size. The goal is for the device to reliably produce enough energy to power artificial heart valves.

HT to Laughing Squid for spotting this one.
