It’s about time some people started working on this… generating power through our footsteps! Yup, kinetic energy! 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.”

We have the Ocean Power Delivery Systems, Floor and Turntiles in Subways, Solar projects (CA just passed a huge home solar panel law), and finally sidewalks. Wohooo for energy!

update: Now a sustainable night club dance floor in which the dancers transfer their disco lovin enegry through the floor to whatever powere the bar, dj, speakers, toilets, or lights need!
