Powering Up, One Step at a Time

British engineers are converting street vibrations into electricity and predict a working prototype by Christmas capable of powering facility lights in the busiest areas of a city. “We can harvest between 5 to 7 watts of energy per footstep that is currently being wasted into the ground” says Claire Price, director of The Facility Architects, the British firm heading up the Pacesetters Project. “And a passing train can generate very useful energy to run signaling or to power lights.” Like solar and wind proponents, vibration harvesters argue that abundant, clean energy is all around us and goes to waste. The challenge is how to store the power efficiently so it provides a continual output even if the vibrations from footsteps or passing trains temporarily taper off.

I don't really know how feasible vibration harvesting is but I agree with any research for alternative forms of energy.
