Design and fabrication of speed bump for energy generation

Abstract

Electricity is a basic part of nature and it is one of the most widely used forms of energy across the globe. Fossil fuels pollute the environment. Nuclear energy requires careful handling of both raw as well as waste material. Therefore, the focus now is shifting more and more towards the renewable sources of energy, which are essential and non-polluting. Energy conservation and conversion are the cheapest new sources of energy. This work includes how to utilize the energy which is wasted when the vehicles passes over a speed breaker. Lots of energy is generated when vehicle passes over it. We can tap the energy generated and produce power by using the speed breaker as power generating unit and installing a rack and pinion mechanism. The vertical force of the moving vehicles will cause the action of rack and pinion mechanism. Then, using a set of gear the produced will be transferred to the generator and power will be generated with its rotation. The energy we save during the day light can be used in the night time for lighting street lights. Such a set-up can be placed independently across city lanes, or along tolls on highways and other inter-city roads, or coupled with speed breakers anywhere in the world. The electricity generated from such a machine can be used to light up street lights, traffic signals etc. In case of busy streets and densely populated areas, it can also be used store energy or charge automobile batteries etc.
