People walk around public spaces--a lot. A group of University of Wisconsin-Madison engineers have develop an inexpensive way to convert footsteps to electricity.
Their brainstorm involves using wood pulp and nanofibers in the flooring.
This does not involve the sun having to be out and could work well in high-traffic places like stadiums or a mall, according to On Wisconsin magazine.
Associate professor Xudong Wang is planning to build a prototype in a high-profile spot on campus...and from there, who knows.
Actually, this is not a new idea...It's being developed elsewhere as well--including England.
Google Laurence Kemball-Cook, for example. That's him in the picture.
People walk--why let that go to waste?
