*Before we introduce our project, we would like to add a few heartfelt
words for the people who will be a part of this project in numerous
ways, people who gave unending support to us.
*Words fall short in expressing our gratitude towards the Head of the
Department Dr. JAMEEL and faculty members of ELECTRICAL
ENGINEERING especially Mr. ZEESHAN HABIB cooperation will be
needed as the project proceeds to success.
*In the end, our special thanks and gratitude towards our parents who
have extended their guidance and support whenever we needed and
have made us what we are today. We hope with their showers of
blessings we would easily be able to complete the project.

 THE OBJECTIVE OF OUR PROJECT IS TO
PRODUCE ELECTRICITY BY VERY LOW
PRICE.
 IN OUR COUNTRY THERE IS TOO MUCH
SHORT FALL OF ELECTRICITY AND WE TRY
TO OVER COME THIS PROBLEM BY NON
CONVENTIONAL SOURCE OF ELECTRICITY.

 Is anyone happy with current situation of
electricity in Pakistan?
 So, this is our small step to try to improve this
situation by our project.
 First of all what does electricity mean to us?
 Electricity- secondary source of energy i.e.
converted from other sources.
We need it for every small thing, still notice it’s
importance only during load shedding.

 Pakistan is facing serious energy crisis at
this time .Pakistan as third world
developing country is lot affected by this
energy crisis in the world .The major
issue is electric crisis which is known as
load shedding Pakistan’s small
manufacturing markets are lot affected
by the rise of energy prices.

 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
6/11/2012 12

13.
 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.

14.
 Roller mechanism has some different
disadvantages.
 Maintenance will be very difficult
 Might cause collision.

 Rack-Pinion assembly gives good mounting
convenience
 Maximum gear losses– 3 to 5%
 Efficiency– 95%

 A rack and pinion gears system is composed
of two gears. The normal round gear is the
pinion gear and the straight or flat gear is the
rack.
 The rack has teeth cut into it and they mesh
with the teeth of the pinion gear.

 The rack and pinion is used to convert between
rotary and linear motion. Rack and pinion can
convert from rotary to linear of from linear to rotary.
 The diameter of the gear determines the speed that
the rack moves as the pinion turns.
 Rack and pinions are commonly used in the steering
system of cars to convert the rotary motion of the
steering wheel to the side to side motion in the
wheels

 Pitch circle radius of pinion=r=100mm=0.1m
 Torque(input)=(5000)*(0.1)=500N.m
 Power
input(mechanical)=(5000)*(0.15)=750watts
 As standard the module is taken as 5mm
 m=D/T
 m=dia of pitch circle of pinion/No.of teeths of
pinion
 m=5mm

 Although we got less electrical
output, we have successfully
explained our idea of generating
electricity from speed breaker.
6/11/2012 21

22.
 Such speed breakers can be designed
for heavy vehicles, thus increasing
input torque and ultimately output of
generator.
 More suitable and compact
mechanisms to enhance efficiency

 In this world where there is shortage of electrical power
supply, this project will be helpful to solve some of the
problems. This project has some advantages which are
 1. The project is economical and easy to install.
 2. This project is non polluting.
 3. Maintenance cost is low.
 4. Installation cost is low.
 5. Will solve some of the electricity problems of the
world.
 6. The electricity produced by this system can be used
to drive an electric motor, or for any other purpose.
 7. This project can be implemented on road and can be
used to lighten the street lamps

 We have to check mechanism from
time to time .
 .It can get rusted in rainy season.
 .It will not work with light weight
vehicle

 Energy is an important input to sustain
industrial growth and standard of living of a
country and can be directly related to energy
consumption. The conventional sources
energy like coal, oil, uranium etc are depleting
very fast and by the turn of the century man
will have to depend upon non conventional
sources of energy for power generation.
 The various types of non-conventional
sources of energy are solar energy, wind
energy,

BYTHIS METHOD WE CAN
REDUCE THE SHORTFALL
OF ELECTRICITY FROM
6000MW TO NEGLIGIBLE.
