This document describes a system to generate electricity from the kinetic energy of vehicles passing over a speed breaker. A roller is mounted on a shaft connected to a belt-pulley arrangement coupled to a DC generator. As vehicles pass over the roller, their kinetic energy is converted to rotational motion that drives the generator to produce electricity stored in a battery. The system aims to harness wasted kinetic energy from vehicles to supplement conventional energy sources.

2. Electricity is most widely used energy
Current situation in India
Conventional sources of energy
Non-Conventional sources of energy
New concept used for generating
electricity by using road speed breaker

3. Conversion of kinetic energy of the
vehicle in rotational motion
Roller is mounted on shaft
Shaft connected to Belt-Pulley
arrangement
It is connected to D.C.Generator

4. D.C.Generator produces electricity
Electricity is stored in a battery
Energy generation system

5. Energy conversion from mechanical to
electrical
To generate electricity using the vehicle
kinetic energy as input
Develop electricity from speed breaker
Energy stored in battery
Can be used to light a bulb

6. Implementation on the road

8. A shaft is a rotating member, usually of
circular cross-section, used to transmit a
power or a motion
Shaft is made of mild steel
It is the main part which bear the load
It should be well designed

9.  Roller offer line contact
 Roller is mounted on Cylindrical shaft
 It is larger diameter than shaft
 On roller rubber is mounted
Roller

10.  Used to provide support at higher speeds,
heavy loads and large sizes
 Housing material is made of grey iron
 Housing provides clean environment for
the bearings to freely rotate
 Increases the performance
 “P205” pedestal bearing is used

11.  Excessive load
 Over heating
 True brinelling
 Fatigue failure
 Lubricant failure
 Corrosion
 Loose fits
 Tight fits

12.  Used to generate electricity
 Works on Faraday’s Law
 D.C.Generator 0.125Hp is used

13. Any change in the
magnetic environment
of a coil of wire will
cause a voltage (emf)
to be ‘induced’ in the
coil. No matter how
the change is
produced, the voltage
will be generated.

15.  Compact construction
 Increases the power transmitting capacity
of the belt
 Smooth quiet operation, even at high
operating speeds.
 V belt drive can operate in any position,
even when belt is vertical

16. Material selected for shaft is mild steel
because of following features:-
 The tensile strength of mild steel is equal
to compressive strength of mild steel
 It is cheaply available
 It is easily machineable

26. MERITS
 Low budget electricity production
 Non-Polluting
 Less floor area
 No obstruction to traffic
 Easy maintenance
 Suitable at parking of multiplexes, malls,
toll booths, signals, etc.

27. DEMERITS
Achieving proper balance of speed and
torque.
For different load vehicles, different size
shafts are to be used.
The system should be used in heavy traffic
location

28.  Wasted kinetic energy of vehicles at
speed breakers is utilized
 The system is non-polluting
 The existing source of energy such as coal,
oil, etc. may not be adequate to meet the
ever increasing energy demands, So this
system will contribute to some extent

29.  It is non- conventional type of producing
the energy.
 This project is a one small step to path of
that way of harnessing energy from
several non-conventional energy sources.
