Most of us have heard about using water and the sun to obtain energy. However, did you ever think about possibly generating power when we walk?
After searching the internet, I found an interesting article on a device that a doctor has created that generates power while he walks. I never would have thought about this, but after reading the article and having this idea presented to me, it makes sense. Walking is something that we do everyday. We can't go anywhere in a short distance, without either a) walking there or b) riding there via a bike, skate boards, roller skates. So why not do something environmentally friendly while going about our daily business?
The article states that at normal walking speeds, it can generate enough power to charge a cell phone. This is more than I would have imagined, however, its definitely something that I think should be looked into. Especially since the doctors main intentions were for places such as Africa.
