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.
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 (SPEED BREAKER

Air Compression and Electricity Generation by Using Speed Breaker with Rack A...IJMER
On roads, speed breakers provided to control the speed of traffic in rushed areas. The
potential energy in terms of weight of vehicle is loss on speed breaker can be utilized for useful
purposes. This paper describes the potential energy of such type of energy available on roads and its
utilization for useful work. The stages of development of a speed breaker device are described and the
mechanism to generate electricity using rack, pinion and speed increasing gear box and generator
and store compressed air with the help of piston cylinder compressor arrangement. Whenever the
vehicle is allowed to pass over the speed breaker 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 pinion there is conversion of
reciprocating motion of rack in to rotary motion of pinion, but the two gears rotate in opposite
direction. So that shafts will rotate with certain RPM these shafts are connected through a belt drive
to the generators, which converts the mechanical energy into electrical energy. The rack is attached
to piston rod of cylinder so downward stroke of rack we can use for air compression in reservoir, with
help of piston cylinder arrangement. Simultaneously reciprocating piston cylinder arrangement
compresses the air and stores it in the reservoir. We can use the generated electricity and compressed
air for different purpose

A recent survey on the energy consumption in India had published a pathetic report that 85,000 villages in India do
not still have electricity. Supply of power in most part of the country is poor. Hence more research and development and commercialization of technologies are needed in this field. India, unlike the top developed countries has very poor roads. Talking about a particular road itself includes a number of speed breakers. By just placing a unit like the “Power Generation Unit from Speed Breakers”, so much of energy can be tapped. This energy can be used for the lights
on the either sides of the roads and thus much power that is consumed by these lights can be utilized to send power to these villages.

Modal Analysis of Fibre Reinforced Composite Beams with a Transverse Crack U...IJMER
In many structures like high speed machineries, aircrafts and light weight structures
composite beams and beam like structures are main constituent elements. Cracks induced in these
structural elements cause serious failure and monitoring of these cracks is essential. The presence of
these cracks influences the dynamic characteristics of the structural elements. Hence the changes in
natural frequencies and mode shapes have been the subject of interest of many investigations. In the
present work two Fiber- Reinforced Plastic (FRP) materials, Graphite Fibre Reinforced Polyamide
and E-Glass Fibre Reinforced Polymer have been selected as beam materials for modal analysis using
ANSYS 13.0. The analysis is carried out for these two beams in different ways. Initially the analysis is
carried out for different orientation of fibres for two beams. Later the effect of dimensions is analyzed
by varying one dimension of the beam at a time by keeping the other two constant. In the next step the
analysis is performed for constant dimensions of each beam for same layer orientation and constant
volume fraction of fibre by introducing transverse cracks of different depths at various positions along
the length of the beam. The results obtained are analyzed.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Electric Power Generation by Speed Breaker Generators
Anyaegbunam F.N.C. (Ph.D.)
Department of Electrical/Electronic and Computer Engineering, Federal University Ndufu-Alike-Ikwo, Nigeria
Abstract: - Electric power is a scarce commodity in Nigeria as in most developing countries like India.
Intermittent power outages are witnessed in various cities and villages. Electricity is the form of energy which is
most widely used in nature. Electric power obtained from the conversion of other sources of energy, like coal,
natural gas, oil, nuclear power and other natural sources are called primary sources. Electricity generation was
first developed in 1800's using Faraday’s dynamo generator. After almost 2 centuries later, the same basic
principles are still being used to generate electricity, but on a much larger scale. The primary energy resources
are the conventional types and are in limited quantity because they are not renewable, and on the other hand
they create pollution to the atmosphere. A revolutionary method of power generation through speed breaker
power generators is proposed as an innovative and useful concept. On speed breakers, tremendous amount of
energy is being wasted by vehicles, and several models were introduced to utilize this energy through speed
breakers. This paper attempts to show different methods of renewable energy generation through speed breaker.
Keywords: -Speed breaker, power generation, renewable energy, chain drive, gears, translator-stator topology.
I. INTRODUCTION
The New York Times reported in 1906 on an early implementation of speed bumps in the U.S.A town
of Chatham, New Jersey, which planned to raise its crosswalks five inches above the road level: "This scheme
of stopping automobile speeding has been discussed by different municipalities, but Chatham was the first to
implement it".
According to information from Ministry of Transport, Nigeria has over 56,000km of roads and
statistics provided by the Ministry of Road Transport & Highways in India show that the lengths of national
highway by 2012 was 76,818 km. In year 2002, 58.8 million and in 2004, 72.7 million vehicles were plying on
Indian roads. The annual rate of growth of motor vehicle population in India has been almost 10 percent during
the last decade [9] [10] [12]. There is tremendous vehicular growth in India year by year. Nigeria has over 50
million vehicles plying on its roads with a growth rate of 15 % in 2012, [11]. On the Roads these vehicles waste
tremendous amount of energy due to speed breakers, the increasing traffic and number of speed breakers on
roads gave rise to the manufacturing of an innovative device which can channel the energy being wasted by
vehicles on speed breakers to some useful work. Different models to harness this energy were introduced
according to the road conditions. After each generation the efficiency of model increased and the limitations
diminished. Different kinds of models have variant designs, some use gears, belts, dynamos etc with different
applications at different places. Each model was encouraged due to limitations of previous ones. This paper
illustrates various models and provides the review of different technologies used in the generation of energy
with the help of speed breakers.
1.1. Use of Only Speed Breakers and not Rough or Plane Roads
Now the question arises as to why only the speed breaker is used and not the rough or plane roads
where the kinetic energy of the vehicle is more than that obtained on the speed breaker. The answer to this
question is obvious; consider for example: A car or any heavy vehicle moving 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 will gain the speed of
nearly 90 mph (due to losses). Now suppose a bicycle is moving with a speed of 20 mph and is going to pass
this roller (which is moving at a speed of 90 mph), then 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, [7]. The rough or plane road will
not provide the torque necessary for energy generation.
1.2. Energy Estimation
When the vehicle moves over the speed breaker, speed breaker reduces its speed. As these breakers
have a little height it gains an increase in its potential energy. A vehicle weighing 1,000kg passes over the
system it pushes the damper to a depth of 10 cm it can produce approximately 0.98 kilowatt power (ideally). So
from one such speed breaker on a busy highway, where about 100 vehicles pass every minute, about one
kilowatt of electricity can be produced every single minute. This type of energy is a non-conventional resource
or renewable energy. 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 [2]. It is a mechatronic type of arrangement. The amount of electricity consumed in one
night by all the street lights around Chennai city (India) is equal to consumption of electricity in a remote village
for one month and 14 days [5]. The design of speed breakers was developed long ago but only utilized by few
nations, as there were limitations of speed breaker power generators. These power generators can be classified
according to their mechanism and the type of power generated through it. The classifications are given below.
II. CLASSIFICATIONS OF SPEED BREAKER POWER GENERATOR
One type of speed breaker design for power generation, may not be suitable for all the road conditions,
therefore, different types of designs are introduced, [5].
2.1.Connection through Chain Drive Mechanism.
When the vehicle comes on the speed breaker, because of its weight, the top portion of the speed
breaker moves downwards and the shaft consisting of the U portion rotates in a particular direction. Due to this
rotation of the shaft, the sprocket will rotate and the rotational energy from one shaft is transferred to the other
shaft with the help of chain drive mechanism, Fig. 1. This rotates the gear on the bottom shaft, which in turn will
help to rotate the gear placed on the motor. This rotation of the gear starts the generator and generates electricity
which can be stored in the battery and can be converted to A.C. current using inverter and can be used for
lighting of the lamps signals sign boards on the road etc. [1].
Fig. 1. Chain Drive Speed Breaker Mechanism
Fig.2. Rack and Pinion Arrangement. Fig.3. Sprocket Arrangement
2.2. Rack and pinion system.
The work is concerned with generation of electricity from speed breakers-like set up. The load will act upon the
speed breaker & further the load will be transmitted to the rack and pinion arrangements, Fig.2. Here the
reciprocating motion of the speed-breaker is converted into rotary motion using the rack and pinion
arrangement. The axis of the pinion is coupled with the sprocket arrangement. The sprocket arrangement is
made of two sprockets, Fig.3, one of larger size and the other of smaller size. Both sprockets are connected by
means of a chain which serves in the transmission of power from the larger sprocket to the smaller sprocket. As
the power is transmitted from the larger sprocket to the smaller sprocket, the speed that is available at the larger
sprocket is relatively multiplied at the rotation of the smaller sprocket [4].
2.3. Direct use of load
The load can be directly used by using reciprocating device,Fig.4.It may be done with the help of shafts and
spring as horizontal rod connected with shaft at its centre and springs at its both ends. This mechanism will give
it a reciprocating motion and hence power can be generated.This motion is used to compress the air using
compressing device and after compression, the air gets collected in a cylinder andcan be further used [3].

The stator is a planar back iron with mounted magnets on it. The arrangement of magnets is N-S-N. There is a
spacer with high permeability between each two adjacent magnets, Fig.5. The operation principle of the SBG
(speed breaker generators) can be described as follows. As the vehicle wheels pass the SBG, the translators will
be pushed down. Since the magnets have provided a high density magnetic field in the air-gaps, motion of
translators will cause induction of voltage in the translator’s windings. The produced power will be transferred
via the flexible wires to output terminal of generators. It should be noted that, the flexible wires can be
interpreted as brush and slip rings in electrical rotating machines [6].

2.5. Pressure through Lever Mechanism
When pressure lever, Fig.8, is pressed the flywheel will rotate by chine sprocket gear mechanism, it will force
the DC generator to rotate because DC generator and flywheel are in same shaft, Fig.7. DC generator will
produce electricity by the rotation of armature coil and generated electricity will be stored in a rechargeable
battery. A rechargeable battery, storage battery, or accumulator can be used as storage device .This electricity
can be used later for different purpose [10].
It can be seen from different designs that the storage devices are used according to convenience of situation, as
it simply depends upon the need, that is, the form of energy required which may be, for electricity, either in
form of direct current [1] or in the form of alternating current[1]. The power also may be stored in the form of
compressed air as mentioned above in section 2.3.

III. IMPICATIONS OF USING SPEED BREAKER
The power generated through speed breaker mechanism can be considered renewable source which does not
pollute the environment. Below are the advantages and challenges of using speed breaker mechanism for power
generation.
3.1. Advantages of using speed breaker as power generator
• Require simple construction methods.
• Free from all types of pollutions.
• It is economical and easy to install.
• Maintenance cost is low.
• This concept is quite promising due to its good efficiency as well as energy recovery criteria.
• No fuel transportation problem.
• No consumption of fossil fuel which is nonrenewable.
• No manual work necessary during generation.
• Energy available all year round.
• We can use it at all places according to desired design.
The Indian Institute of Technology, IIT, Guwahati has evaluated the machine and recommended it to
the Assam ministry of power for large scale funding,. IIT (Indian Institute of Technology) design department
says it is a “veryviable proposition” to harness thousands of megawatts of electricity untapped across the
country every day, [8].It is therefore recommended that Nigerian Ministry of power should also begin
implementation of this technologyto improve power generation across the country. A storage module like an
inverter will have to be fitted to each such rumble strip to store this electricity. The cost of electricity generation
and storage per megawatt from speed-breakers will be nearly USD500,000 as opposed to about $1.2million in
thermal or hydro power stations [8].
3.2.Challenges
i. Selecting suitable generator.
ii. Selection of springs.
iii. Achieving proper balance of speed and torque.
iv. Such speed breakers can be designed for heavy vehicles, thus increasing input torque and ultimately output
of generator and hence it will not work with light weight vehicle.
v. Require more suitable and compact mechanisms to enhance efficiency.
vi. We have to check mechanism from time to time in short span of period.
vii.Because of Rain water it may get damage.
IV. CONCLUSION
In the coming days, demand for electricity will be very high as it is increasing every day, speed breaker
power generator will prove a great boom to the world in theFuture. The Aim of this research is to introduce
another innovative method of green power generation in order to contribute toward developing the world by
enriching it with utilization of availableresources in more useful manner. Any country, especially Nigeria and
other developing nations, can only develop when there is steady and available power supply forits citizens and
