Piezoelectrics installed in Tokyo railway station floors generate power, wastes it

The East Japan Railway Company has been running tests on a "power-generating floor" since the beginning of January 2007, but they've just installed the system for public testing in several areas of the Tokyo station. Using piezoelectrics similar to that we've seen before in a UK discotheque, the Japanese company says the power-generating capacity of the flooring has increased ten-fold over its initial results, and they now expect to generate 1,400kW/sec per day. With that, they plan to power the display pictured above, which shows the power generatd by the floor. Sound a little redundant? Fear not: they plan on using the juice to operate automatic ticket gates in the future.
