Energy-Generating Floors to Power Tokyo Subways

When the East Japan Railway Company (JR East) decided to invest in alternative energy sources, it only had to look to its users for the perfect source of energy. Recently the company decided to update their Tokyo Station with a revolutionary new piezoelectric energy generating floor. The system will harvest the kinetic energy generated by crowds to power ticket gates and display systems!

Anmerkung: Eine nicht ganz neue Neuigkeit, aber sie zeigt auf welch vielfälltige Weise man Energie gewinnen kann.
