GENERATING ELECTRIC POWER FROM SPEED BREAKER USING GENERATORS
PRINCIPLE OF GENERATOR

• Mechanical energy is converted into electrical energy.
• The turning of a coil in a magnetic field produces motional emfs .Since the component of the velocity perpendicular to the magnetic field changes sinusoidally with the rotation, the generated voltage is sinusoidal or AC.
• This process can be described in terms of Faraday's law when you see that the rotation of the coil, magnetic flux changes through the coil and therefore generates a voltage.
WORKING
• The shaft of the generator is connected to the axis of the rolling speed breaker.
• When the automobile crosses over the speed breaker the shaft is rotated.
• Hence the rotating shaft of generator produces electrical energy.
• The electrical energy generated is stored in power unit.
IMPLEMENTATION
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

ELECTRICITY GENERATION FROM SPEED BREAKER
Introduction

 Very new and innovative concept
 Non –Conventional Energy Source.
 This Makes Use Of WASTED OF ENERGY TO generate ELECTRCAL ENERGY.
DEVELOPMENT PART OF INNOVATION
The principle of operation of this mechanism is based on principle of conversion of potential energy to kinetic energy and then this kinetic energy in turn can be used to generate electricity
CONDITION OF GEENERATING ELECTRICITY FROM SPEED BREAKER
Storage Of electricity Generated From The movement Of traffic .
Continuous Flow Of traffic.
Look of Breaker to Generate Electricity
The “electro-kinetic road ramp ”system can be raised to act as a speed bump or laid flat ,
So that driver can not realize they are passing over it
HOW GENERATING THE ELECTRICIT FROM SPEED BREAKER
The bump or breaker consists of a series of panels set in pad virtually flushed in motion under the road this turn rotate a geared shaft loaded with spring the output of shaft coupled with dynamo to convert kinetic energy into electricity
COMPONENT
Return Spring
Bearing
Rack & pinion
Sprocket
Chain drive
gear wheel
Shaft
Generator
Battery
BASIC PRINCIPLE:
 Simple energy conversion from Mechanical to Electrical.
 To generate electricity using the vehicle weight (potential energy) as input
 Possible using 3 different mechanisms:
I. Crank-shaft mechanism
II. Roller mechanism
III. Rack- Pinion mechanism
Why Rack- Pinion mechanism??
Crank-shafts are required to be mounted on bearings which creates balancing problem leading to mechanical vibrations which in turn damage the bearings.
Secondly as bearings are of sliding type, any occurrence of variable load( which is bit obvious in case of vehicles!!) leads to balancing problem.
Roller mechanism has some different disadvantages.
Maintenance will be very difficult
Might cause collision.
Spring mechanism in reciprocating motion
Basic figure to how reciprocating converted in rotatory motion
reciprocating motion due speed bump and spring
Challenges we faced!!
Selecting suitable generator.
Selection of springs.
Achieving proper balance of speed and torque.
Scope, Merits and Uses
Low Budget electricity production
Less floor area
No obstruction to traffic
Easy maintenance
Uses: Charging batteries and using them to light up the streets, etc.
FUTURE SCOPE
Such speed breakers can be designed for heavy vehicles, thus increasing input torque and ultimately output of generator.
More suitable and compact mechanisms to enhance efficiency.

An energy crisis is any great bottleneck (or price rise) in the supply of energy resources to an economy. It usually refers to the shortage of oil and additionally to electricity or other natural resources. An energy crisis may be referred to as an oil crisis, petroleum crisis, energy shortage, electricity shortage electricity crisis. While not entering a full crisis, political riots that occurred during the 2007 Burmese anti-government protests were initially sparked by rising energy prices. Likewise the Russia-Ukraine gas dispute and the Russia-Belarus energy dispute have been mostly resolved before entering a prolonged crisis stage. Market failure is possible when monopoly manipulation of markets occurs. A crisis can develop due to industrial actions like union organized strikes and government embargoes. The cause may be ageing over-consumption, infrastructure and sometimes bottlenecks at oil refineries and port facilities restrict fuel supply. An emergency may emerge during unusually cold winters. EMERGING SHORTAGES Crisis that currently exist include; • Oil price increases since 2003 - Cause: increasing demand from the U.S and China, the falling state of the U.S. dollar, and stagnation of production due to the U.S. occupation of Iraq. Iraq is #3 in the world (besides Saudi Arabia and Iran) for its oil reserves. However some observers have stated the global oil production peak occurred in December 2005. If this is correct it is also to blame. • 2008 Central Asia energy crisis, caused by abnormally cold temperatures and low water levels in an area dependent on hydroelectric power • South African electrical crisis Solution for Energy Crisis NEXT time on the roads, don’t scoff at the speed-breakers. They could actually light up small villages off the highway. This project is about GENERATION OF ELECTRICITY with the SPEED BREAKERS. Generally when vehicle is in motion it produces various forms of energy like, due to friction between vehicle’s wheel and road i.e. rough surface HEAT Energy is produced, also when vehicle traveling at high speed strikes the wind then also heat energy is produced which is always lost in environment and of which we can’t make use of….OR directly we can say that all this energy that we can’t make use of is just the WASTAGE OF ENERGY that is abundantly available around us. In this project we are just trying to make use of such energy in order to generate an ELECTRICAL ENERGY. This project will work on the principle of “POTENTIAL ENERGY TO ELECTRICAL ENERGY CONVERSION” Potential energy can be thought of as energy stored within a physical system. This energy can be released or converted into other forms of energy, including kinetic energy. It is called potential energy because it has the potential to change the states of objects in the system when the energy is released If h is the height above an arbitrarily assigned reference point, then Kinetic energy of an object is the extra energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its current velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Negative work of the same magnitude would be required to return the body to a state of rest from that velocity. The kinetic energy can be calculated using the formula: In this project a mechanism to generate power by converting the potential energy generated by a vehicle going up on a speed breaker into kinetic energy. When the vehicle moves over the inclined plates, it gains height resulting in increase in potential energy, which is wasted in a conventional rumble strip When the breaker come down, they crank a lever fitted to a ratchet-wheel type mechanism (a angular motion converter). This in turn rotates a geared shaft loaded with recoil springs. The output of this shaft is coupled to a dynamo to convert kinetic energy into electricity. A vehicle weighing 1,000 kg going up a height of 10 cm on such a rumble strip produces approximately 0.98 kilowatt power. So one such speed-breaker on a busy highway, where about 100 vehicles pass every minute, about one kilo watt of electricity can be produced every single minute.

ABSTRACT:

In the present scenario power becomes major need for human life. Due to day-to-day
increase in population and lessen of the conventional sources, it becomes necessary that we must depend on
non-conventional sources for power generation. While moving, the vehicles posses some kinetic energy and it
is being wasted. This kinetic energy can be utilized to produce power by using a special arrangement
called “POWER HUMP”.
The Kinetic energy of moving vehicles can be converted into mechanical energy of the shaft
through rack and pinion mechanism. This shaft is connected to the electric dynamo and it produces electrical
energy proportional to traffic density. This generated power can be regulated by using zenor diode for
continuous supply .All this mechanism can be housed under the dome like speed breaker, which is called
hump.
The generated power can be used for general purpose like streetlights, traffic signals. The
electrical output can be improved by arranging these power humps in series this generated power can be
amplified and stored by using different electric devices. The maintenance cost of hump is almost nullified. By
adopting this arrangement, we can satisfy the future demands to some extent.

OBJECTIVES:

To design a low cost machine.
To utilize a small amount of energy wasted in daily life.
To reduce cost per unit of power generation.
To utilize alternate sources of energy.

METHODOLOGY:

While moving, the vehicles possess some kinetic energy and it is being wasted. This kinetic energy can
be utilized to produce power by using a special arrangement called POWER HUMP. It is an Electro-Mechanical
unit. It utilizes both mechanical technologies and electrical techniques for the power generation and its
storage. POWER HUMP is a dome like device likely to be speed breaker.

The 3 different mechanisms proposed are:
-Roller mechanism
-Crank-shaft mechanism
-Rack- Pinion mechanism

Rack and pinion mechanism: This mechanism is most popularly used. This is because of the disadvantages of

other mechanisms:
Crank shaft mechanism: Crank-shafts are required to be mounted on bearings which creates balancing
problem leading to mechanical vibrations which in turn damage the bearings.Secondly as bearings are of
sliding type, any occurrence of variable load( which is bit obvious in case of vehicles!!) leads to balancing
problem.
Roller mechanism: Here maintenance will be very difficult and it Might cause collision.
The Rack-Pinion assembly gives good mounting convenience . Te efficiency is 95% with 3-5% gear losses.

Whenever the vehicle is allowed to pass over the dome it gets pressed downwards then the springs
are attached to the dome are compressed and the rack which is attached to the bottom of the dome moves
downward in reciprocating motion. Since the rack has teeth connected to gears, there exists conversion of
reciprocating motion of rack into rotary motion of gears but the two gears rotate in opposite direction. A
flywheel is mounted on the shaft whose function is to regulate the fluctuation in the energy and to make the
energy uniform. So that the shafts will rotate with certain R.P.M. these shafts are connected through a belt
drive to the dynamos, which converts the mechanical energy into electrical energy. The conversion will be
proportional to traffic density.
Whenever an armature rotates between the magnetic fields of south and north poles, an E.M.F
(electro motive force) is induced in it. So, for inducing the E.M.F.armature coil has to rotate, for rotating this
armature it is connected to a long shaft. By rotating same e.m.f, is induced, for this rotation kinetic energy
of moving vehicles is utilized. The power is generated in both the directions; to convert this power into one
way a special component is used called zenor diode for continuous supply. All this mechanism can be housed
under the dome, like speed breaker, which is called HUMP. The electrical output can be improved by arranging
these POWER HUMPS in series. This generated power can be amplified and stored by using different electrical
devices.

ADVANTAGES:

• The cost of electricity generation and storage per mega watt from speed-breakers will be nearly Rs 1
crore as opposed to about Rs 8 crore in thermal or hydro power stations.
• It utilizes unused energy.
• we can lighten our steeet lamps..
• extra electricity can be send to villages also.

DISADVANTAGES:

we have to check mechanism from time ot time .

It will not work with light weight vehicle.

It can get rusted in rainy season.

MECHANICAL PART
2.1 WORKING PRINCIPLE:

Whenever the vehicle is allowed to pass over the dome, it gets pressed downwards. As the springs are attached to the dome, they get compressed and the rack, which is attached to, the bottom of the dome moves down in reciprocating motion. Since rack has teeth connected to gear there is conversion of reciprocating motion of rack in to rotary motion of gears, but the two gears rotate in opposite direction. So that shafts will rotate with certain RPM these shafts are connected through a chain drive to the dynamos, which converts the mechanical energy into electrical energy.
Now made to rotate a wheel in one direction by supplying power to shaft, while other made to rotate freely on the shaft, as the free wheel is inserted in the gears. We can insert a flywheel is mounted on the shaft when the main function is to avoid energy fluctuation.

INTRODUCTION
Before starting I have one question to you all who is really very happy with the current situation of the electricity in India? I suppose no one. So this is my step to improve the situation of electricity with an innovative and useful concept ie Generating Electricity from a Speed breaker First of all what is electricity means to us? Electricity is the form of energy. It is the flow of electrical Power. Electricity is a basic part of nature and it is one of our most widely used forms of energy. We get electricity, which is a secondary energy source, from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources. Many cities and towns were built alongside water falls that turned water wheels to perform work. Before electricity generation began slightly over 100 years ago, houses were lit with kerosene lamps, food was cooled in iceboxes, and rooms were warmed by wood-burning or coal-burning stoves. Direct current (DC) electricity had been used in arc lights for outdoor lighting. In the late-1800s, Nikola Tesla pioneered the generation, transmission, and use of alternating current (AC) electricity, which can be transmitted over much greater distances than direct current. Tesla's inventions used electricity to bring indoor lighting to our homes and to power industrial machines. How is electricity generated?
Electricity generation was first developed in the 1800's using Faradays dynamo generator. Almost 200 years later we are still using the same basic principles to generate electricity, only on a much larger scale.
The rotor(rotating shaft) is directly connected to the prime mover and rotates as the prime mover turns. The rotor contains a magnet that, when turned, produces a moving or rotating magnetic field. The rotor is surrounded by a stationary casing called the stator, which contains the wound copper coils or windings. When the moving magnetic field passes by these windings, electricity is produced in them. By controlling the speed at which the rotor is turned, a steady flow of electricity is produced in the windings. These windings are connected to the electricity network via transmission lines.
Now I m throwing some light on the very new and innovative concept ie GENERATING ELECTRICITY FROM A SPEED BREAKER. Producing electricity from a speed breaker is a new concept that is under going research. The number of vehicles on road is increasing rapidly and if we convert some of the kinetic energy of these vehicle into the rotational motion of roller then we can produce considerable amount of electricity, this is the main concept of this project. In this project, a roller is fitted in between a speed breaker and some kind of a grip is provided on the speed breaker so that when a vehicle passes over speed breaker it rotates the roller.
This movement of roller is used to rotate the shaft of D.C. generator by the help of chain drive which is there to provide 1:5 speed ratios. As the shaft of D.C. generator rotates, it produces electricity. This electricity is stored in a battery. Then the output of the battery is used to lighten the street lamps on the road. Now during daytime we don’t need electricity for lightening the street lamps so we are using a control switch which is manually operated .The control switch is connected by wire to the output of the battery. The control switch has ON/OFF mechanism which allows the current to flow when needed.
One question that u all are thinking is why I have apply this on the speed breaker and not on the rough road or plane road where the kinetic energy of the vehicle is more then what I m getting on the speed breaker I m giving u one example, just think over it.
A car or any heavy vehicle is coming with a speed of 100 mph on the road and passing over this roller which is fitted at the level of the road then this roller is gaining the speed nearly somewhere 90 mph (due to losses). So now suppose a cycle is coming with a speed of 20 mph and is going to pass this roller (which is moving at a speed of 90 mph) due to this difference in the speed there will be a collision that is the main reason for using this concept on the speed breaker

GEAR DESIGN
Gears have been around for hundreds of years and are as old as almost any machinery ever invented by mankind. Gears were first used in various construction jobs, water raising devices and for weapons like catapults.
Nowadays gears are used on a daily basis and can be found in most people’s everyday life from clocks to cars rolling mills to marine engines. Gears are the most common means of transmitting power in mechanical engineering.
Gears are used in almost all mechanical devices and they do several important jobs, but most important, they provide a gear reduction. This is vital to ensure that even though there is enough power there is also enough torque(is a movement of force).
This site is a valuable resource about gear and gear design.
ADVANTAGES:
It is used to power production
It reduced to electric supply
No need labors
We can use all places
It is easy way to power production
