Footsteps harnessed for power

The next time you walk through a busy corridor, don't be surprised if it is well lit. A couple of MIT graduate students are on a quest to generate electricity from footsteps by installing a special kind of floor which will power train stations as well as other commuter-heavy areas such as shopping malls. Guess malls will save a whole lot more on their power bill during the holiday season should this system be installed as everyone comes out to get their fair share of retail therapy. The floor depresses slightly when you step on it, which simulates the effect of walking on sand. I wonder when will we see this kind of floors being installed in public places in a drive to create a greener environment.
