Creating Electricity by Jumping?

 . . . or walking!  Two MIT graduate students won the Student Post Competition at the 2007 Holcim Forum.  This forum provides a place for academicians and practitioners to discuss sustainable construction.  Tad Jusczyk and James Graham put forward the notion of a “Crowd Farm.”  It turns “the mechanical energy of people walking or jumping into a source of electricity.”  By working with a very large group of people, e.g., a railway station or a rock concert, electricity could be made and used for other purposes.

At this point, this concept is expensive to integrate into buildings, but as they continue to work on the project, they hope to make it more affordable.
