NOVELTY - The system has a predetermined number of piezoelectric devices (400) which are adapted for producing electrical power. The piezoelectric devices are connected to a power conditioning unit by electrical conductors. The electrical power is generated when a vehicle traverses the location of the piezoelectric devices and the power conditioning unit. The piezoelectric devices are embedded in a road. The power conditioning supplies electrical power to battery charging stations for charging batteries of electrical vehicles. The power conditioning unit supplies electrical power to roadside lights.    USE - Power harvesting system for harvesting power on roads. Uses include but are not for harvesting power on highways, railways, and airport runways for implementation in power emergency communication units, mobile communication base stations, roadside advertisements, and roadside battery recharging stations.    ADVANTAGE - Enables the charge on the capacitor to remain until utilized by a load connected to a load output since the rectifier is adapted to hold the collected charge at the capacitor unit utilized by energy utilizing load. Exhibits better utilization of generated charge and exhibits higher energy efficiency since the rectifying bridge prevents the electrical charge accumulated on the capacitor from returning to the transducer once the load is removed from the transducer. Minimizes the energy load due to the cabling electrical resistance since the energy management unit serves a section of the road including lanes in both traveling direction. Prevents the power supply to be interrupted when cars are absent or traffic is slow or the number of cars is small since the energy storage e.g. large capacitor or rechargeable battery is used for storing the energy to be used when needed.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) a method for harvesting energy; and    (2) a power harvesting device.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic perspective view of the boxed-shape piezoelectric transducer.
