Researchers are currently working on various ways to harvest the energy of human movement in urban settings. They are working on turning the mechanical energy of body movements into a source of electricity. Applications for the technology could range from health to recreation. Researchers at MIT have been working on generating electricity from human movement in urban settings in a project called Crowd Farm. In Japan, scientists have connected generators to the turnstiles in railway stations to generate power. University of Wisconsin-Madison associate professor Tom Krupenkin is working on placing salty liquid inside the soles of shoes to generate electricity.
