US and Canadian scientists have built a novel device that effortlessly harvests energy from human movements. The adapted knee brace, outlined in the journal Science, can generate enough energy to power a mobile phone for 30 minutes from one minute of walking. The first people to benefit could be amputees who are being fitted with increasingly sophisticated prosthetics. "All of the new developments in prosthetics require large power budgets," Dr Douglas Weber of the University of Pittsburgh, and one of the authors of the paper, told BBC News. "You need power to run your neural interface; you need it to run your powered joint, and so on. "Getting that power is going to be really important."

Pretty novel idea.

Similar here, I never use my celly. I'm not a phone person, anyway. I prefer face-to-face. But this is a good idea anyway, for those crazy texters, especially.

Yeah, guilty as charged. Texting gets me thru the workday. As well as playing games on my cell, and checking my email periodically. When I go online for gaming or for checking email/news it eats up my battery like crazy.
