Generate electricity by your movements

MIT duo see people-powered "Crowd Farm" from MIT News

The so-called "Crowd Farm," as envisioned by James Graham and Thaddeus Jusczyk, both M.Arch candidates, would turn the mechanical energy of people walking or jumping into a source of electricity.

A Crowd Farm in Boston's South Station railway terminal would work like this: A responsive sub-flooring system made up of blocks that depress slightly under the force of human steps would be installed beneath the station's main lobby. The slippage of the blocks against one another as people walked would generate power through the principle of the dynamo, a device that converts the energy of motion into that of an electric current.

Wonder how much electricity would it generate if installed on CST or Dadar stations in Mumbai !!
