what about the possibility of putting piezoelectric steps in subways
like new york and boston, etc- so many humans walking up and sown
those steps, even the timy charge given off in those cells could add
up to a lot- i unfortunately dont have the technical knowhow to
determine if it would be cost effective, but i would love to see some
development of this as a potential...
