Power-Generating Backpack

Juniper Foo | Sep 15, 2005

Remember the old familiar refrain: "Pack up your troubles in your old kit bag, and smile, smile, smile..." Well, now there's something to smile about. Prof Larry Rome of biology at Penn State Uni has developed the Suspended-load Backpack which harnesses mechanical energy from something as simple as walking. According to Rome, lugging 38kg of weight in the backpack can generate up to 7.4 watts of energy. That's enough juice to power multiple devices ranging from MP3 music player to PDA, to GPS and a mobile phone. The idea is based on a simple magnetic coil generator similar in principal to hand-cranked radios and flashlights that work with some rhythmic shaking. Forrest Gump, here we come!
