Two MIT grad students in the architecture program have an idea to harness the energy of moving crowds using blocks under the floor that depress and rub against one another when stepped upon, generating electricity. The concept, which they call a Crowd Farm, would work best in a place like a train station, where you have a lot of people moving all the time. According to this article, while one step can power a single lightbulb for one second, 28,527 steps could power a train for one second.
Which, you know, won’t really get you very far but whatever.
As a test case, the guys built a chair that lights up when you sit down. Great for reading, not so much for relaxing but again, whatever. Very cool!
What will those crazy MIT kids think of next? Place your guesses in the comments.
