Baby Steps: Powering Up with One Step at a Time
July 28, 2006
British engineers are working on a prototype to convert street vibrations into electricity. By Christmas, they predict a working model 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."
