3. INTRODUCTION
 In our country there is a shortage of
electricity and we try to overcome this
problem by non conventional sources of
energy.
 To sort out the energy crises it led to the idea
of generating power using speed breaker.
 A large amount of energy is wasted by
the vehicles due to friction.
 Electricity can be generated using vehicles by
its motion (Kinetic Energy) and weight
(Potential Energy) as an input.

4. Scope, Merits and Uses
 Low budget electricity production.
 Low floor area and no obstruction to traffic.
 Easy maintenance.
 Energy available through out the year.
 Pollution free power generation.
 No fuel transportation required.
 No need of man power during power
generation.
 More suitable and compact mechanism to
enhance efficiency.
 Uses : Charging batteries and using them
to light up the streets etc.

5. Basic Principle
 Simple energy conversion
from mechanical to electrical.
 To generate the electricity using
the vehicle’s speed and weight as
input.
 Possible using 2 different
mechanisms Roller mechanism
Rack and pinion mechanism

6. Gear Mechanism
 A mechanism for transmitting motion for some
specific purpose.
 GEAR : A gear is a wheel with teeth on its outer
edge.
 The teeth of one gear engages with the teeth of other.

7. Gear
 Two meshed gears always rotate
in opposite directions.
 Two gears are of different
diameters.
Driven gear
Driver gear

8. Gear ratio
 Generally, the gear ratio is
calculated by counting the teeth
of the two gears, and applying
the following formula :
Gear ratio = Number of teeth on driven gear
Number of teeth on driver gear

9. Gear ratio- calculation
 A 100 tooth gear drives a
25 tooth gear . Calculate
the
gear ratio of the meshing
teeth.
Gear ratio = Number of teeth on driven gear
Number of teeth on driver gear
Gear ratio = driven 25 = 1
driver 100 4
This is written as 1:4

10. ROLLER MECHANISM
Roller mechanism has some
disadvantages :
 Maintenance will be very difficult.
 Might cause collision.

11. RACK AND PINION MECHANISM
The various equipments are
:



 Rack-pinion
Sprockets Gears
Flywheel
Dynamo

12. Rack and pinion- It convert linear motion
to rotational and vice versa
sprocket mechanism-transfer
rotary between two shafts
Flywheel- this is use to regulate the
energy and
maintain the energy at an uniform level so that
the shaft rotate at an uniform r.p.m
Dynamo- It is the dc generator which is
use to generate current . Generates current
as per the faraday’s law.

13. CONSTRUCTION

14. Working procedure
Here the reciprocating motion of the speed-breaker is converted
into rotary motion using the rack and pinion arrangement.
Rack and pinion gears normally change rotary motion into linear
motion, but sometimes we use them to change linear motion into
rotary motion.
The axis of the pinion is coupled with the sprocketarrangement.
The axis of the smaller sprocket is coupled to a gear arrangement.
Finally the gear arrangement is coupled with thegenerator.

18. Conclusion
 Power generation does not require any
fuel input and the running cost is very
less.
 There are some non- conventional methods
of producing energy. This project is a step to
path of exploring the possibilities of energy
from several non- conventional energy
sources.
