'Crowd Farm' Converts Footsteps into Electricity

quote[wo MIT students have found the next new source of energy: you.

A new technology developed by the graduate students would take the energy generated by human movement, such as walking or jumping, in crowded settings and turn it into electricity.

The so-called "Crowd Farm" would work something like this: A responsive sub-flooring system would be placed under, say, the platform of a subway terminal. The blocks that make up the system would depress slightly under the force of human footsteps. As the blocks slipped against each other, they would generate power in the form of an electric current. ]

What a great idea!
