Design of Rack and Pinion Mechanism for Power Generation at Speed Breakers

Need is the mother of all inventions and innovations. Man has improved the standards of everything around him to his comfort, need and desire. In the long run of science, since the time that science has taken a rigid form, man has stated, restated, invented, modified, discovered and re-discovered many facts, concepts and methods. In such a venture, a country's growth in the world economy largely bases upon its power generation rate, per-capita consumption rate and most importantly, efficiency of the both. As technology is advancing, the consumption of power is steadily rising. So the challenges of power generation and its cost of production, play an important role in the countries competence in the world economy. Thus "The need of the hour is power". So the problem identified is power generation and means to make it cheaper. The world is growing at a rapid pace. Among many vital sectors of our social life, transportation sector has a key role to play. It is an ever growing sector with the escalating population, growing needs and creeping number of vehicle users. The traffic on the roads becomes doubled or tripled, at alarming rates. If vehicular motion can be put to generate useful power, it can be put to effective use. This idea has mothered the invention of "power generation through speed breakers", inspired by various other existing designs. In this paper an attempt has been made to generate power using speed breakers through rack and pinion mechanism by tapping the energy and utilizing it for various purposes such as lightening the street lights, etc.
