People Power in the New York Times

It turns out that I’m not the only one thinking about how to convert human energy into electricity these days. The New York Times reports today that Canadian researchers have developed a gadget that harvests energy from the knee joint as people walk, using a knee-brace with a mechanical device that can collect about 5 watts or electricity (enough to power a few cell-phones or other small electronics). Plus, it doesn’t take any extra effort to generate power using it – all you have to do is walk, and the juice starts flowing. It’s unlikely that these things will be on the market any time soon, but its really good to know that there are guys in white coats in labs out there making these things. Maybe one of them is working on a hand-crank cuisinart battery at this very moment…
