ABSTRACT
Energy is the primary need for survival of all organisms in the universe. Everything what happens in the
surrounding is the expression of flow of energy in one of the forms. But in this fast moving world, population is
increasing day by day and the conventional energy sources are lessening. The extensive usage of energy has
resulted in an energy crisis over the few years. Therefore to overcome this problem we need to implement the
techniques of optimal utilization of conventional sources for conservation of energy. My paper 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. The kinetic energy of the moving vehicles can be converted into mechanical
energy of the shaft through rack and pinion mechanism. Then, this mechanical energy will be converted to
electrical energy using generator which will be saved with the use of a battery. The energy we save during the
day light can be used in the night time for lighting street lights. Therefore, by using this arrangement we can
save lot of energy which can be used for the fulfillment of future demands
. INTRODUCTION
Increasing demand of energy adds to the need of identifying non-conventional resources of energy. In
my paper, I will discuss about power generation from speed breaker and the possible mechanism required for it.
II. WORKING
This project explains the mechanism of electricity generation from speed breakers.[1][2][3] The vehicle load
acted upon the speed breaker system is transmitted to rack and pinion arrangements. Then, reciprocating motion of the
speed-breaker is converted into rotary motion using the rack and pinion arrangement where the axis of the pinion is coupled
with the sprocket arrangement. The sprocket arrangement is made of two sprockets. One of the sprocket is larger in
dimension than the other sprocket. Both the sprockets are connected with chain which transmits the power from the larger
sprocket to the smaller sprocket. As the power is transmitted from the larger sprocket to the smaller sprocket, the speed that
is available at the larger sprocket is relatively multiplied at the rotation of the smaller sprocket. The axis of the smaller
sprocket is coupled to a gear arrangement. Here we have two gears with different dimensions. The gear wheel with the larger
diameter is coupled to the axis of the smaller sprocket. Hence, the speed that has been increased at the smaller sprocket
wheel is passed on to this gear wheel of larger diameter. The smaller gear is coupled to the larger gear. Therefore, as the
larger gear rotates it increases the speed of the smaller gear which is following the larger gear and multiplies the speed to
more intensity. Though the speed due to the rotary motion achieved at the larger sprocket wheel is less, as the power is
transmitted to gears, the final speed achieved is high. This speed is sufficient to rotate the rotor of a generator and is fed into
the rotor of a generator. [4]The rotor which rotates within a static magnetic stator cuts the magnetic flux surrounding it, thus
producing the electric motive force (emf). This generated emf is then sent to an inverter, where the generated emf is
regulated. This regulated emf is now sent to the storage battery where it is stored during the day time and can be used in
night time for providing power to street lights.
ADVANTAGES
Power generation with low cost and using non-conventional energy sources which will help us to conserve the
conventional energy sources to meet the future demand.
By using this method, electricity will be generated throughout the year without depending on other factors.
Easy for maintenance and no fuel transportation problem.
Pollution free power generation.
Less floor area required and no obstruction to traffic.
No need of manpower during power generation.
IX. CONCLUSION
"Electricity plays a very important role in our life”. Due to population explosion, the current power generation has
become insufficient to fulfill our requirements. In this project we discover technology to generate electricity from speed
breakers in which the system used is reliable and this technique will help conserve our natural resources. 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, it’s high time to think of alternative resources. 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.
