Paper Title
Design & Development of Power Hump

Energy crisis has become a great bottleneck in our sophisticated life and the demand for electricity continues to rise in all parts of the world. The most optimistic estimates have fossil fuel lasting no more than 100 years; however, they may become economically undesirable soon. According to statistics provided by the Ministry of road Transport & Highways, in India the lengths of national highway till year 2012 was 76,818 km and 15-20 highways are there in each state. The annual rate of growth of motor vehicle population in India has been almost 10 percent during the last decade. In the current scenario, when every day the newspapers are flooded with news of accidents due to high speed, speed breakers are becoming more and more crucial. These help to reduce the speed of vehicles, thereby enabling a comparatively smooth drive. This energy loss on speed breakers can be utilized for useful purposes. This project describes the potential of one such type of energy source available on roads and its utilization for useful work.This project is about harnessing the energy which is being wasted when the vehicle slows down near the speed breaker. Special arrangement called as “POWER HUMP” is used. This arrangement consists of rack & pinion, gears, chain sprocket, dynamo, battery etc., Power Hump setup is placed under the speed breaker. When vehicle moves over the Power Hump, rack moves downwards and meshes the pinion in contact. Pinion shaft is connected to dynamo by means of different gear pairs and chain sprockets. Intermediate shafts are used to place gear pairs and chain sprockets, with help of which velocity ratio is increased. Electrical power output of the Power Hump setup is calculated by measuring the voltage and current.
