This document describes a mechanism for generating electricity from the kinetic energy of vehicles passing over speed bumps. It introduces different mechanisms considered, including a spring coil mechanism and rack pinion mechanism. When a vehicle passes over the speed bump, the downward force is converted into rotational motion through these mechanisms. This rotation is used to power an electric dynamo, which generates electricity that can be stored in a battery. The document discusses the working principle and provides diagrams of components like the rack and pinion gears and dynamo. Advantages include utilizing wasted energy and providing pollution-free power generation.

2.  Introduction
 Different mechanisms
 Spring coil mechanism
 Rack pinion mechanism
 Merits and demerit
 Scope and uses
 Conclusion

3. Very new and innovative concept
Non –Conventional Energy Source.
This Makes Use OF WASTED OF
ENERGY TO generate ELECTRCAL
ENERGY.

4. A large amount of energy is wasted at the
speed breakers through friction , every time a
vehicle passes over it.
So electricity can be generated using the
vehicle weight (potential energy) as input.
So, this is a small step to try to improve this
situation.
Speed breaker with some mechanism
involved converts this wastage of energy into
useful form.

8. Working principle
 Simple energy conversion from Mechanical to
Electrical.
 To generate electricity using the vehicle weight
(potential energy) as input.

9. •The material used in
construction of speed
breakers is steel.
•The shape of speed
breaker is parabolic.

10.  Vehicle approaching the speed breaker

13.  When vehicle passes over
speed breaker, it moves
downward due to weight
of vehicle.

14.  Working of Electric
Dynamo.
 The magnetic lines of
force are cut by the
rotating wire coil, which
induces a current to flow
through the wire.
 The mechanical energy of
rotation is thus converted
into an electric current in
the armature.

16. Transfers rotary
motion between
two shafts.

17. The input gear
transfers power
to the output
gear.

18. Converts
rotational motion
into linear
motion.

20.  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.

21.  The axis of the pinion is coupled with the sprocket
arrangement.
 The axis of the sprocket is coupled to a dynamo.
 Finally the dynamo is coupled with the battery.
 And with the help of battery we can light a bulb.

26. merits
 Pollution free power generation
 No manual work necessary during generation.
 Energy available all year round.
 Uninterrupted power generation during day and night.
 Maximum utilization of energy.

27.  This mechanism is very economical and easy
to install.
 Two protocols of this type of speed breakers
are developed in India .not practically
implemented till date.
 Practically implemented in New Jersey, China
and Indonesia.
 Lots of researches and investigations are
going on to practically utilize this technique

28.  It can be implemented at metropolitan cities. so that
more electric power is produced.
 Arrangement of whole setup is easier.
 The stored electricity could satisfy the daily
requirement of electric power.
