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

SPRING COIL MECHANISM
Working principle Simple energy conversion from Mechanical to
Electrical. To generate electricity using the vehicle weight
(potential energy) as input.
DESIGN OF THE SPEED BREAKER
•The material used in construction of speed breakers is steel.
•The shape of speed breaker is parabolic.
WORKING PROCESS
Vehicle approaching the speed breaker
CONTINUED… When vehicle passes
over speed breaker, it moves downward due to weight of vehicle.
ELECTRIC DYNAMO 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.
SPROCKET MECHANISMTransfers rotary motion between two shafts.
GEAR MECHANISMThe input gear transfers power to the output gear.
RACK AND PINIONConverts rotational motion into linear motion.
CONSTRUCTIONAL DETAILS
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.
CONTINUED…
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.
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.
SCOPE AND USES 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
CONCLUSION 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.
