This is pretty amazing.  Tokyo's metro station is using their riders to create energy for ticket gates and display systems.  This new piezoelectric energy generating floor has a wide range of applications and I can't help but start fantasizing about the possibilities.  If you think about it any area with heavy foot traffic could help generate energy.  The possibilities really are endless.
