In Japan someone is experimenting a new way to obtain energy from people passing every day on the East Japan Railway Company in Tokyo. They have installed 25 mq of pizoelectric crystal under the floor where every day thousands of people walk. Those crystals turn each compression and decompression in an electrical discharge. Today the energy produced is used only as a demonstration but in the future it could be used for the display screen of the station, for example. The floor is expected to produce 1.400 kw/sec per day. It is not the only experiment of producing "alternative energy" using human movement. We have already written about what sport and fitness can do, but there are also the Spinnaker Tower in Portsmouth and eco-night club in King's Cross, in Great Britain.
