This document describes a project to generate electricity from the kinetic energy of moving vehicles using a speed breaker system. It includes: 1) A list of 4 team members and their enrollment numbers working on the project. 2) An overview of the system which uses a rack and pinion mechanism connected to an electric dynamo to convert the mechanical energy of vehicles passing over the speed breaker into electrical energy. 3) Calculations showing the system could generate over 10kW of power per day, enough to power 4 street lights at night.

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.

4. • 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.

5. basIC PrINCIPLe
Simple energy conversion from Mechanical to Electrical.
To generate electricity using the vehicle weight (potential
energy) as input
Possible using 3 different mechanisms:
I. Crank-shaft mechanism
II. Roller mechanism
III.Rack- Pinion mechanism

6. Why Rack-Pinion
mechanism??
•Crank-shafts are required to be mounted
on bearings which creates balancing
problem leading to mechanical
vibrations which in turn damage
the bearings.
•Secondly as bearings are of sliding type,
any occurrence of variable load
( which is bit obvious in case
of vehicles!!) leads to
balancing problem.
•In roller mechanism ,maintenance will be very difficult.
•So, we use the rack-pinion(figure).

•This project explains the mechanism of electricity generation
from speed breakers.
•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.

10. • 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.

11. •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.
•The rotor which rotates within a static magnetic stator cuts the
magnetic flux surrounding it, thus producing the electric motive
force (emf).

12. POWER
CALCULATIONS
• The mass of any vehicle travelling over the speed
breaker= 300Kg (Approximately)
• Height of speed brake = 15 cm = 0.15 m
• Work done = weight of the body x distance travelled by
the vehicle
• Here, Weight of the Body = 300 Kg x 9.81 = 2943 N
• Distance traveled by the body = Height of the speed
breaker = 15cm
• Power = Work done/Second = (2943 x 0.15)/60 = 7.3575
Watts Output

13. • Power developed for 1 vehicle passing over the speed
breaker
• Arrangement for 1 minute = 7.3575 watts
• Power developed for 60 minutes (1 hr) = 441.45 watts
• Power developed for 24 hours = 10.5948 Kw
• This power generated by vehicles is more than sufficient to
run four street lights in the night time.

14. ADVANTAGES
• The project is easy to install.
• The project is eco-friendly.
• Maintenance and installation cost are low.
• Pollution free power generation.
• Less floor area required.
• No need of manpower during power generation.

15. •Don’t want to see India as an energy deficient country.
•It should be of least cost, as well as of less weight.
•Efficiency should be as high as possible.
•Losses should be minimum.
OUR GOALS

16. Future scope
•The shortage of light can be reduced at some extant.
•Wastage of energy can be minimized.
•Flywheel can be used to increase the rotational speed of
the Dynamo shaft.
•It may also be used for light vehicle.

17. •It is an non conventional type of producing the energy.
•Existing source of energy may not be adequate to meet
the ever increasing demands, So this project is a one
step to path off that way.
•This project will be helpful to solve some of the Electricity
shortage problems.
