Human body movement could be potential power source

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.
