JAPAN: East Japan Railway has announced the results of its experiments with a 6 m² piezoelectric floor covering, which was fitted at the ticket gates of a Tokyo station where it used the movement of passengers to generate electricity.

It worked, but only just. Production peaked at 10 kW-sec a day - equivalent to lighting a 100 W bulb for 100 sec - but the output decreased after three weeks and 800?000 passengers due to the degradation of the piezoelectric elements.
