INTRODUCTION
In the present day scenario power has become themajor need for human life. Energy is an important input in all the
sectors of any countries economy. The day-to-day increasing population and decreasing conventional sources for
power generation, provides a need to think on non-conventional energy resources [1][2]. Here in this paper we are
looking forward to conserve the kinetic energy that gone wasted, while vehicles move. The number of vehicles
passing over speed breaker on road is increasing day by day. Beneath speed breaker, setting up an
electro-mechanical unit known to be power hump, could help us conserving this energy and use it for power
generation. The electrical output can be improved by arranging these power humps in series. This generated power
can be stored, by using different electrical devices. We can supply this energy to street lights, traffic lights, and
nearby areas, and thus helps in country‟s economy. We could make it more efficient, by also having a solar panels
LITERATURE REVIEW
The energy crisis is any great bottleneck in the supply of energy resources to an economy. The studies to sort out
the energy crisis led to the idea of generating power using speed breaker. Firstly, South African electrical crisis has
made them implemented this method to light up small villages of the highway. The idea is basic physics, to convert
the kinetic energy into electrical energy that gone wasted when the vehicle runs over speed-breaker [5]. Since then,
a lot has been done in this field. An amateur innovator, Kanak Gogoi in Guwahati has developed a similar
contraption to generate power, when a vehicle passes over speed-breaker. The idea has caught the eye of
IIT-Guwahati, which funded the pilot project related to generate electricity from speed-breakers. They has
evaluated the machine and recommended to the Assam government. Their work has provided the need to think on
this alternative to generate electricity on the large scale, as it proves to be a boon to the economy of the country.
OBSERVATIONS
As far as the experiment concerns, we have two related observations with regard to the voltage generated to the
variations in speed and load [11]. The following were the two illustrations:
a). Let us consider the load(heavier vehicle) is constant on the speed breaker. Now we have the voltage produced,
to the variations in the speed of the vehicle. If the vehicle runs slowly then it certainly applies the pressure on the
speed breaker for a long time so the voltage produced will be most in this case. While we keep on increasing the
speed, the vehicle rushes over the speed breaker, the pressure keep on decreasing so as the voltage produced. The
graph plotted between these two variables [14][15], is shown Fig.3.
CONCLUSION
In coming days, this will prove a great boon to the world, since it will save a lot of electricity of power plants that
gets wasted in illuminating the street lights. As the conventional sources are depleting very fast, then it‟s time to
think of alternatives. We got to save the power gained from the conventional sources for efficient use. So this idea
not only provides alternative but also adds to the economy of the country. Now, vehicular traffic in big cities is
more, causing a problem to human being. But this vehicular traffic can be utilized for power generation by means
of new technique called “power hump”. It has advantage that it does not utilize any external source [12]. Now the
time has come to put forte these types of innovative ideas, and researches should be done to upgrade their
implication.
