People powered 'Crowd Farm'

A very cool idea. Probably a much bigger initial investment than harvesting solar or wind power, but this is great for reminding us about the cause and effect of our actions.

From physorg:

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. Their proposal took first place in the Japan-based Holcim Foundation's Sustainable Construction competition this year.
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.
I especially like this idea: And while the farm is an urban vision, the dynamo-floor principle can also be applied to capturing energy at places like rock concerts, too. "Greater movement of people could make the music louder," suggests Jurcyzk.
