This document discusses generating electricity from speed breakers using vehicles' kinetic and potential energy. It describes two mechanisms - roller and rack/pinion mechanisms. The rack/pinion is more efficient (70% vs 50%) and easier to design for, converting the linear motion of the speed breaker into rotational motion to power a generator. Charts show voltage increasing with vehicle speed and electrical load. In conclusion, this method generates pollution-free power from vehicles at low cost, providing a solution to energy shortages.

4. 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.

5. 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.

6. 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

7. 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.

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

9. 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

10. 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

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

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

13. 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.

15. 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 sprocket arrangement.
 The axis of the smaller sprocket is coupled to a gear arrangement.
 Finally the gear arrangement is coupled with the generator.

19. 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.
