In October 2006, an experiment started at the Marunouchi North Gate of JR Tokyo station to test electricity generating power and durability. The electricity generated when people walk on the special floors is stored in an electric double layer capacitor. On the first day of the test, the total output generated from early morning to 14:00 reached approximately 1 Wh. "The output is small and it will take some more time to finish verification on durability and other factors before the actual debut," said a source from JR East.
