Energy Harvesting: Roadway Bump

Abstract

The present invention aims to prepare a mechanism to harvest energy from road’s bump. This mechanism consists of bump, springs, linear bar gear, gears, holding shafts, dc motors, booster inverter and battery. It converts kinetic energy to electrical energy using mechanical compartment installed in the system. In the busy traffic situation, vehicle approaching the road bump and ramps it repeatedly. Road bump moves the linear rack gear up and down. Using one way bearing, this force has been transferred continuously to the dc motor shaft with the attached pinion gear. The dc motor shaft will keep on rotating in both positions, whether the linear rack gear is moving up or down. As the shaft is continuously rotating, the dc motors will start to produce electrical energy and been transferred to the battery.
