ELECTRICITY
GENERATION FROM SPEED
BREAKER
Introduction:
Is anyone happy with current situation of
electricity in India???
 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.

 OBJECTIVES:
“Shaping Imagination”
 “Electricity”-Need of the hour

Scope, Merits and Uses
Low Budget electricity production
 Less floor area
 No obstruction to traffic
 Easy maintenance
 Suitable at parking of multiplexes, malls,
toll booths, signals, etc.
 Uses: Charging batteries and using them
to light up the streets, etc.

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

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.


Roller mechanism has some different
disadvantages.
Maintenance will be very difficult
 Might cause collision.


What we did???
Rack-Pinion assembly gives good
mounting convenience
 Maximum gear losses– 3 to 5%
 Efficiency– 95%

Construction of generator:
Initial experiments- DC motor as
Generator
 How is electricity generated???
 Basic principle of generation of electricity.
 What we did???

Challenges we faced!!
Selecting suitable generator.
 Selection of springs.
 Achieving proper balance of speed and
torque.

What we achieved???
We LEARNT a lot.
 Constructed our own generator by
applying the basic principle.
 Although we got less electrical output, we
have successfully explained our idea of
generating electricity from speed breaker.

Future Scope:
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.
