Out Of Juice? Just Strap on This Knee Brace
OUT OF JUICE? JUST STRAP ON THIS KNEE BRACE
February 11th, 2008
Researchers from Simon Fraser University in British Columbia have developed a knee brace like device, that when worn while walking will charge an internal battery. The Biomechanical Energy Harvester (sounds more like an implant - it ain't) generates power at the end of a walker's step similar to that of an electric or hybrid car braking (that's according to the researchers). Wearing the device on each leg can generate 5 watts of electricity at a normal pace. At a fast pace the device can generate up to 13 watts. With just one minute of walking and the Biomechanical Energy Harvester can power a standard cell phone for 30 minutes of talk time. That puts the Hymini to shame. Although, I doubt it costs a mere $49 like the Hymini. Dare I say: “The green energy race is on’.
