INTRODUCTION
 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 and speed
(kinetic energy) as input.
 So, this is a small step to try to
improve this situation.

DIFFERENT MECHANISMS
 SPRING COILMECHANISM
 ROLLER MECHANISM
 CRANK-SHAFT MECHANISM
 RACK- PINION MECHANISM

SPRING COIL MECHANISMS
 Working principle conversion of mechanical energy to pneumatics energy which is
convertedtoelectricalenergy.
DESIGN OF THE SPRING:-
 The actual height of spring is 0.3m before loading.
 The deflection of the spring is given by
 δ = 64 w *n*N*R^3 /(G^4)
 where
 δ-deflection (in our case maximum δ =0.1m)
 w=designed load
 R= mean diameter of coil
 n=no of spring turns
 G= Modulus of rigidity = 8*10^4 N/m^2
 N= No. of springs
 The no of turns in the spring to get the deflection of 0.1m is given by
 n= (0.1)G^4/(64 w*N*R^3)

CONSTRUCTION OF THE SPEED BREAKERS
 Here we are making the speed breaker of vibrating type,
when a vehicle crosses the speed breaker, it gets pressed and
then it gets back to its original position.
 Dimensions of speed breaker:-
o Height : 0.2m
o Width : 0.4m
o Length: 4m
 The material used in construction of speed breakers is steel.
 The shape of speed breaker is trapezoidal .
Fig 4.1

CONSTRUCTION OF THE TRENCH
o Height: 0.35m
o Length : 4m
o Width :0.45m
 The bottom layer of the trench
is filled with concrete or with
wooden plates of 0.5m.
 This is for cushion effect.
Fig 4.2

WORKING PROCESS
 Vehicle approaching the speed breaker.
 Maximum load on the speed breaker is when the vehicle is on the middle of
the speed breaker.
 When the pressure in the FRL unit exceeds the defined level the valve opens
and the pressurized air is given to the nozzle.

NOZZLE:-
 The diameter of the inlet of nozzle must be greater than
outlet.
 Here the pressure energy is converted to kinetic energy that
is pressure = high velocity.
 This high velocity compressed air when hits the impeller
,makes it to rotate.

Fig 4.6

 It consists of a circular disc on the periphery of which have number of buckets
evenly spaced are fixed. Each bucket is divided in to 2 symmetrical parts by a
dividing wall is know as splitter.
 When the air strikes the runner ,it rotates & continues rotation due to inertia.
ALTERNATOR:-
 An electrical generator is a machine which converts mechanical energy in to
electrical energy.
 The output of the alternator is used to light the street lights & is rectified & stored
in batteries.

Merits Demerits
Pollution free power generation. Selecting suitable generator.
No obstruction to traffic. Selection of springs.
Low Budget electricity
production
Achieving proper balance of
speed and torque.
Easy maintenance It gives low electric output

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 Jersy, China and Indonesia.
 Lots of researches and investegations are going on to practically
utilise this technique.

CONCLUSION
 The existing source of energy such as coal, oil etc may not be
adequate to meet the ever increasing energy demands. These
conventional sources of energy are also depleting and may be
exhausted.
 These are some non-conventional methods of producing energy. This
project is a one step to path of exploring the possibilities of energy
from several non-conventional energy sources.
