4. INTRODUCTION
 In the present day scenario power has become the major
need for human life.
 Energy is an important input in all the sectors of any
countries economy.
 The day-to-day increasing population and decreasing
conventional sources for power generation, provides a need
to think on non-conventional energy resources.
 Here in this project we are looking forward to conserve the
kinetic energy that gone wasted, while vehicles move.

5. CONTINUED..
 The number of vehicles passing over speed breaker on road
is increasing day by day.
 Beneath speed breaker, setting up an electro-mechanical
unit known piston/water tank assembly could help us
conserving this energy and use it for power generation.
 This generated power can be stored, by using different
electrical devices.
 We can supply this energy to street lights, traffic lights, and
nearby areas, and thus helps in country’s economy. 5

6. OBJECTIVE
 In our country there is to much short fall of electricity and we
try to overcome this problem by non conventional source of
electricity
 To tap the potentially useful potential energy from vehicles
plying on the road.
 The objective of our project is to produce electricity by very
low price.

7. POSSIBLE USING DIFFERENT
MECHANISMS
 SPRING COIL MECHANISM
 RACK- PINION MECHANISM
 CRANK-SHAFT MECHANISM
 ROLLER MECHANISM

8. WHY WE USE SPRING COIL AND RACK
PINION MECHANISM?
Roller mechanism
 Maintenance will be very difficult.
 Might cause collision.
Crank shaft mechanism
 Crank-shafts are required to be mounted on bearings which
creates balancing problem.
 Mechanical vibrations produces which in turn damage the
bearings.
 Because of above disadvantages We use ONLY SPRING
COIL MECHANISM & RACK- PINION MECHANISM.
 AMONG THIS WE USE SPRING COIL MECHANISM.

11. SPRING COIL MECHANISM
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.
11

12. CONTINUED..
 Due to this force is applied on the piston/spring mechanism in the
water tank.
 And then water is coming outside of the tank.
 Now one valve is there which measured the pressure & Valve is
maintaining of flow of water.
12

13. CONTINUED..
 This water is passing on rotor blade which rotates & one chain
belt is there so Generator is also rotates with rotor.
 This generator generates electricity which can be used for
lighting of the lamps on the road or it may be stored in the
battery and can be converted in AC current using inverter and
used for lighting of the lamps, signals sign boards on the road.

16. SPRING SELECTION.
 The function of spring is to bear a load and twist by application of
force from the speed breaker. The spring should be such that it
can generate enough force to pressurize the water in tank by
piston.
 Based on the strength, functional requirements and the
properties of the candidate materials as earlier stated, Stainless
steel was selected as the most suitable material for its excellent
ability to withstand high stress, good fatigue resistance and long
endurance for shock and impact loads.
 The spring used is in helical shape.
 The spring stiffness and spring deflection for the chosen spring
are 17500 N/m and 0.1M.

17. TURBINE
 A small pelton wheel turbine is used .
 A pelton turbine consists of a set of buckets or cups
mounted on a hub.
 A pelton turbine operates in air with the wheel driven
by jets of high pressure water hitting the buckets or cups. 17

18. GENERATOR
 An electrical Generator is a machine which converts
mechanical energy into electrical energy (or power).
 For this model a permanent magnet DC generator with drum
type armature, wave winding is suitable which is shown in fig

21. BATTERY
 The battery used in the project work is rated for 7AH at 12V.
 It is a free type rechargeable battery generally called as
secondary cell. It can supply continuously for a specified
interval time.
 Current ratings varies in the case of lead-acid battery with
high ampere –hour capacity is called heavy duty battery.

23. CIRCUIT DESCRIPTION
 Resistance (R1=1k, R2=50k variable, R3=100k, R4=100ohm,
R5=3k, R6=100ohm, R7=50ohm or 84ohm or 100ohm).
 Use 50 ohm with 500ohm variable to fine tone output. For me I
have use 84 ohm.
 Capacitor-none polarized (c1=100nf, c2=10nf, c3=1uf, c5=10uf).
For c5 you can use 5.6uf-400v polarized, its better.
 Capacitor-polarized (c4=10uf).
 IC (555timer).
 Transistors (q1=c2016 or (9013 but use 220ohm resistor instead
of 100 ohm), q2=2n3055).
 Transformer with/out centertap-220v to 12v step-down, 1A or
more.
 12v battery 10A, or use any ampere.
 This circuit will work only on 12v not more than 14v or IC will
burn. 23

27. 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.
