Roadside power harvesting for auto street light

Present development of the world is measured by the amount of energy consumption. Energy of today world is generated from conventional energy sources mostly which are decreasing day by day. Moreover, these conventional energy sources causes pollution and responsible for global warming of the world. To solve these problems, researchers are trying frequently to explore new sources of energy which are clean, environment friendly, sustainable. This research is focused on auto lighting on street lights utilizing the jerking pressure which is wasted during the vehicles passes over speed breaker in roadside. In this work, the amount of electricity generation depend on spring constant, displacement of rack, number of vehicle, weight of the vehicle, gear ratio and number of gear combination are addressed as well as the techniques to increase the efficiency of the system is discussed. In response of public demand, number of vehicles is increased day by day for transportation facilities and hence this system can fulfil the demand of electricity in roadside and small area also. Auto street lights secure safety to the passer-by at roadside and raise awareness towards the new technology.
