Take a walk to charge your cell phone

Canadian and American Scientists have been working together to create a "Knee Generator". What is a Knee Generator you ask? Let me explain.

Walking is a lot like driving, stopping and going - with each stride, muscles are causing the body to accelerate and decelerate. Just like Hybrid cars take advantage of the stop and go driving, using regenerative braking, where energy normally dissipated as heat drives a generator instead. This is the same principal applied to the Knee Generator. The device which resembles a knee protector, assists the muscles in making the body decelerate while simultaneously generating electricity.
