Knee-powered Charger in the Works

Indeed, our body is a wonderful and mysterious creation. In the words of popular singer john mayer
, it is a wonderland. No wonder a group of American and Canadian scientists has created a three-and-a-half pound knee brace that can turn the power of our legs to energy. According to one of the researchers, Dr. Max Donelan, of Simon Fraser University in Canada:
"People-power is a desirable thing to tap into it because we are these incredible batteries. We store enough energy in fat to charge a 1000 kilogram battery. With our device, you could walk for one minute and get ten minutes of talk time on your cellphone."Unfortunately, its development proves to be very costly. Even without this technology, a knee brace alone is worth $1,000.
