Growing clean energy down at the Crowd Farm

Subway stairwellHere’s a different sort of crowdsourcing. The “Crowd Farm” is the brainchild of two MIT architecture students, and it’s a system designed to harness the physical movements of large masses of people and turn it into usable electricity – imagine contributing to the metro station’s lighting by climbing the stairs, for example. It’s a great idea – and like a lot of great ideas, a couple of people have thought of it already. Let’s hope any arguments over patents don’t get in the way of something that can reduce our collective carbon footprints, eh? [Image by yeuxrouge]
