Human Energy Powers Japanese Subway Station

With the vast U.S. subway systems on the East Coast, this could be an excellent energy-saving solution metropolitan transportation authorities should explore.


With human foot traffic the most easily available energy, this new power source has been installed in the flooring in what’s commonly believed to be the busiest subway station in the world.

In the latest drive to harness alternative energy, the East Japan Railway Company (JR East) has installed a revolutionary new piezoelectric energy generating flooring in their Tokyo subway station.JR East recently converted the floor covering from rubber to stone tiles. The total floor space utilized for this power-generating system now encompasses approximately 25 square meters. The company estimates generating around 1,400 kilowatts per day from the system, enough energy to power all the station’s systems.This system will collect the kinetic energy generated by subway travelers entering the turnstile and will power ticket gates and electric displays.
