US Patent 7830071 Power harvesting apparatus, system and method

The present invention relates to an apparatus system and method for power harvesting on roads and highways using piezoelectric generator. The invention is to provide a system and a method for power harvesting comprising a plurality of piezoelectric devices embedded in a road and configured to produce electrical power when a vehicle traverses their locations. The system includes a power conditioning unit and electrical conductors connecting said piezoelectric to said power conditioning unit. Harvested energy may be used locally in proximity to the energy generation location, stored for later use or transferred to be used in remote location.
