A Tokyo rail company, JR East, has put footstep-powered generators under ticket wickets using a milliwatt-tracking counter, and 700,000 daily commuters. For the next two months, the railway company will be using the vibrations of human footsteps at Tokyo Station to generate up to 100 milliwatts per second per person that walks through. The idea is to be able to generate enough electricity to power the wickets themselves and their display panels regularly. Who wants to take the Riverdance troupe there and screw up their results?
