1. ABSTRACT
In the present scenario power becomes major need for human
life. Due to day-to-day increase in population and lessen of the
conventional sources, it becomes necessary that we must depend on
non-conventional sources for power generation .While moving, the
vehicles posses some kinetic energy and it is being wasted. This kinetic
energy can be utilized to produce power by using a special arrangement
called “POWER HUMP”.
The kinetic energy of moving vehicles can be converted into
mechanical energy of the shaft through rack and pinion mechanism.
This shaft is connected to the electric dynamo and it produces electrical
energy proportional to traffic density. This generated power can be
regulated by using Zener diode for continuous supply. All this
mechanism can be housed under the done like speed breaker, which is
called hump.
The generated power can be used for general purpose like
streetlights, traffic signals. The electrical output can be improved by
arranging these power humps in series this generated power can be
amplified and stored by using different electric devices. The
maintenance cost of hump is almost nullified. By adopting this
arrangement, we can satisfy the future demands to some extent.

2. INTRODUCTION
In the present scenario power becomes the major need for
human life .The availability and its per capita consumptions are
regarded as the index of national standard of living in the present day
civilization. Energy is an important input in all the sectors of any
countries economy. Energy crisis is due to two reasons, firstly the
population of the world has been increased rapidly and secondly
standard of living of human beings has increased. India is the country,
which majorly suffers with lack of sufficient power generation.
The availability of regular conventional fossil fuels will be the
main sources for power generation, but there is a fear that they will get
exhausted eventually by the next few decades. Therefore, we have to
investigate some approximate, alternative, new sources for the power
generation, which is not depleted by the very few years. Another major
problem, which is becoming the exiting topic for today is the pollution.
It suffers all the living organisms of all kinds as on the land, in aqua
and in air. Power stations and automobiles are the major pollution
producing places.

5. 5
Therefore, we have to investigate other types of renewable
sources, which produce electricity without using any commercial fossil
fuels, which is not producing any harmful products. There are already
is existing such systems using renewable energy such as solar wind),
OTEC (ocean thermal energy conversions) etc…for power generation.
The latest technology which is used to generate the power by such
renewable energy” POWER HUMP”.

4. EQUIPMENT REQUIRED
4.1. Rack and Pinion Gears
The rack and pinion used to convert between rotary and
translation motion. The rack is the flat toothed part, while the pinion is the
gear. Rack and pinion can convert rotary to linear or from linear to rotary
motion.
4.2. Ball Bearings
A roller-element bearings is a bearing which carries a load
by placing round elements between the two pieces. The relative motion of
the pieces causes the round elements to roll(tumble) with little sliding.
They reduce the friction and transmit the motion effectively.
4.3. Spur Gear
It is a positive power transmission device with definite
velocity ratio. It is preferred for adjusting some linear misalignment. It
should have high wear and tear, shock-absorbing capacity.
4.4. Flywheel
The primary function of flywheel is to act as an energy
accumulator. It reduces the fluctuations in speed. It absorbs the energy
when demand is less and releases the same when it is required.
4.5. Shaft
It is a rotating element, which is used to transmit power from
one place to another place. It support the rotating elements like gears and
flywheels. It must have high torsional rigidity and lateral rigidity.
4.6. Generator
It is a device which converts mechanical energy into electrical energy. The
generator uses rotating coils of wire and magnetic fields to convert
mechanical rotation into a pushing direct electric current through
“Faraday’s law of electromagnetic induction”.

6. BASIC PRINCIPLE
While moving, the vehicles possess some kinetic energy and it
is being wasted. This kinetic energy can be utilized to produce power
by using a special arrangement called POWER HUMP. It is an Electro-
Mechanical unit. It utilizes both mechanical technologies and electrical
techniques for the power generation and its storage. POWER HUMP is
a dome like device likely to be speed breaker. Whenever the vehicle is
allowed to pass over the dome it gets pressed downwards then the
springs are attached to the dome is compressed and the rack which is
attached to the bottom of the dome moves downward in reciprocating
motion. Since the rack has teeth connected to gears, there exists
conversion of reciprocating motion of rack into rotary motion of gears
but the two gears rotate in opposite direction. A flywheel is mounted
on the shaft whose function is to regulate the fluctuation in the energy
and to make the energy uniform. So that the shafts will rotate with
certain R.P.M. these shafts are connected through a belt drive to the
dynamos, which converts the mechanical energy into electrical energy.
The conversion will be proportional to traffic density.
Whenever an armature rotates between the magnetic fields of
south and north poles, an E.M.F is induced in it. So, for inducing the
E.M.F. armature coil has to rotate, for rotating this armature it is
connected to a long shaft. By rotating same e.m.f is induced, for this
rotation kinetic energy of moving vehicles is utilized. The power is
generated in both the directions; to convert this power into one way, a
special component is used called zener diode for continuous supply. All
this mechanism can be housed under the dome, like speed breaker,
which is called HUMP. The electrical output can be improved by

10. 10
arranging these POWER HUMPS in series. This generated power can
be amplified and stored by using different electrical devices.
6.1 Possible Using Different Mechanism:-
 Spring coil mechanism
 Rack –Pinion mechanism
 Crank-shaft mechanism
 Roller mechanism
6.1.1Spring Coil Mechanism
A spring is defined as an elastic body, whose function is to
distort when loaded and to recover its original shape when the load is
removed. The very important applications of springs are as follows:

11. 11
• To cushion, absorb or control energy due to either shock or vibration
as in car springs, railway buffers, air-craft landing gears, shock
absorbers and vibration dampers.
• To apply forces, as in brakes, clutches and spring loaded valves
• To control motion by maintaining contact between two elements as in
cams and followers.
• To measure forces, as in spring balances and engine indicators.
• To store energy, as in watches, toys, etc.

6.1.2. RackAnd Pinion Mechanism
Speed breaker POWER GENERATOR Converters basically new
concept of non-conventional energy generation. It is electro-mechanical
energy generating machine. This machine converts reciprocating motion
in to rotary motion. The rotational power is stored in flywheel &
flywheel rotates dynamo, which generates electricity.

12. 12
Here first important point is how we get reciprocating motion,
which is prime input in the system. For that we use weight of Moving
vehicle on the Speed breaker. We put our machine underneath the
Sped breaker installing different units. All the units are connected to
the common shaft using chain and sprocket drive.
The head of rack is brought up to level beneath the speed breaker
surface. When vehicle moves on the speed breaker, the rack it will be
pushed down. The rack is attached with free wheel type pinion that
rotates in one direction only. The rack & pinion arrangement convert
reciprocating motion in to rotary motion.
Fig.6.1.2:-Rank-pinion mechanism

13. 13
This rotary motion is further magnified using reciprocating motion
in to rotary motion-belt & pulley drive. The output of pulley is attached
with flywheel which stores kinetic energy and transfer to dynamo which
generate electricity with zero cost. A "generator" and "motor" is
essentially the same thing: what you call it depends on whether electricity
is going into the unit or coming out of it. A generator produces
electricity. In a generator, something causes the shaft and armature to
spin. This generated power is used for various application required by
different use.
6.1.3. Crank-Shaft Mechanism
It converts the reciprocating motion into useful rotary motion of
the output shaft. Whenever the vehicle is going on the speed breaker, the
breaker goes speed downward. So, the potential energy is converted into
kinetic energy of the crank shaft.
Fig.6.1.3:-Crankshaft Mechanism
6.4. Roller Mechanism
6.1.4.1Rollers
The material which is used in hardened EN8Properties of EN8:
EN8 is an unalloyed medium carbon steel with good tensile strength. It is

14. 14
normally supplied in cold drawn or as rolled. Tensile properties can vary
but are usually between 500-800 N/mm2. EN8 is available from stock in
bar can be cut to your requirements.
Fig.6.1.4:-Roller mechanism
In this mechanism, a roller is fitted in between a speed
breaker and some kind of a grip is provided on the speed breaker so that
when a vehicle passes over speed breaker it rotates the roller. This
movement of roller is used to rotate the speed of D.C. generator by the
help of chain drive which is there to provide different speed ration. As the
shaft of D.C. generator rotates, it produces electricity. This electricity is
stored in a batter. Then the output of battery is used to lighten the street
lamps on the road. Now during day we don’t need electricity for
lightening the street lamps so we are using a control switch which is
manually operated. The control switch is connected by wire to the output
of the battery. The control switch has ON/OFF mechanism which alloys
to flow when needed.
