Road Tyre Friction Used to Generation of Electrification

Abstract

The current scenario of energy demands in India have waded new research areas for hunting the alternative energy resources to compensate the polluting non renewable resources. It brings larger importance to the idea of harvesting the frictional energy between the Roads and the vehicular tyres. This is exerted as a stress on the road surface accompanied by Heat dissipation. This wasted form for energy can be made productive by using Piezoelectric Generator and Thermoelectric Generator. Piezoelectric Generator generates electricity in response to stress acting on its mechanical axis while Thermoelectric Generator generates power when an ambient temperature difference is provided. These are embedded below the road surface with suitable insulations and proper structure to improve its performance. This system would have very low capital cost when compared to the total cost of power generation, transmission and distribution in conventional power generation methods with the life time of this system in concern . The pollution free electricity thus generated from the road by using these generators can be stored in a battery and later used for the domestic electrification. This method will be best suited for the electrification of all time loads like Traffic signals, street lights, lighting especially in highways.
