Generation of Electricity Using Road Transport Pressure
[attachment=66645]
Abstract
Energy is the basic need for the development of the modern world. For meeting up the regular demand of
energy we need to design a system that will produce electricity without destroying the nature. This paper attempts to show
how man has been utilizing and optimizing kinetic energy. Researches show that the world has already had its enough
shares of its energy resources. Fossil fuels pollute the environment. Nuclear energy requires careful handling of both raw
as well as waste material. The focus now is shifting more and more towards the renewable sources of energy, which are
essentially, non-polluting. This paper attempts to show how energy can be produced, stored and used using the road
transport pressure or any kind of pressure. The number of vehicles passing over the speed breaker in roads is increasing
day by day. There is possibility of tapping the energy and generating power by making the speed breaker as a power
generation unit. The generated power can be used for the lamps near the speed breakers and this will be a great boon for
the rural villages too.
INTRODUCTION
For reduction of carbon dioxide emission, renewable energies are considered as proper alternative energy [1].
Renewable energies mainly refer to the wind, solar, biomass and marine currents which are less harmful to
environment, attracting a wide attention of researchers in design and development of renewable energy
conversion systems. Although improvement of renewable energy converters is in a fast rate, the systems to
extract the wasted energy in conventional energy conversion systems are not developed as much as its
technologies. In many systems and processes, dissipation of energy is inevitable whatever renewable or
conventional energy was used. For instance, as a car passes over a speed-breaker, most of car kinetic energy will
be wasted as heat in it. On other hand, to ensure the security of the populated areas of streets, the speed-breakers
are required, whatever we used electrical cars or the cars consuming gasoil. There are numerous similar cases
which such vast energies are wasting. Like an elevator during going down, a car during going down on a sloppy
street, where regardless the used type of energy or efficiency of systems energy is systematically wasting. It is
mainly due to condition that the systems are operation in it. In this paper, we focus on the fixed speed-breaker at
the streets since a high amount of vehicles kinetic energy is wasting there. There are thousands of crowed cities
with enormous flow of vehicles offers high amount of energy can be considered as near to urban resource of
energy. Also, extraction of such energy allows eliminating of transmission system between the remote areas and
urban area for lightings purposes. There is a little literature about extraction of kinetic energy from flow of
vehicle in the streets. There is so little and invalid literatures in generation of electricity by speed breakers that
but the most common approaches can be seen in [2- 3] these proposed systems, mostly small radial flux
generators with ineffective topologies have been employed. Therefore it is necessary to design a suitable and
efficient topology for design of an energy conversion system for extraction of kinetic energy of vehicles. This
paper presents a novel speed-breaker generator (SBG) for extraction of kinetic energy of vehicle flow in the
street. This device converts the kinetic energy of the vehicles into electric energy. This is done by moving plate
installed on the road, this plate take the stroke motion of the vehicles and convert it to the rotary motion by
crank mechanism and it generates the electricity [3-4].
PROPOSED SYSTEM DESIGN & OPERATION
A. System design & configuration
When automobile vehicle are running on the specialized Speed Breaker. This will create pressure on the
pressure leaver which is kept under specialized speed breaker. As a result flywheel will rotate and this rotation
of the flywheel will cause the DC generator to produce electricity. This electricity can be stored by a
rechargeable battery by charging the battery. The produced or stored electricity is used for lighting bulb during
night time on the road side.
Project Electrical Circuit Diagram
Switches that can be turned to different positions to make a connection with the contacts in that particular
position. A rechargeable battery, storage battery, or accumulator is a type of electrical battery. It comprises one
or more electrochemical cells, and is a type of energy accumulator. It is known as a secondary cell because its
electrochemical reactions are electrically reversible. Rechargeable batteries come in many different shapes and
sizes, ranging from button cells to megawatt systems connected to stabilize an electrical distribution network.
Several different combinations of chemicals are commonly used, including: lead–acid, nickel cadmium (NiCad),
nickel metal hydride (NiMH), lithium ion (Li-ion), and lithium ion polymer (Li-ion polymer). When electricity
is produced in DC generator, current passes through the rectifier and rechargeable battery is charged. When
power is needed during the night time, selector switch is on and rechargeable battery supplies required power.
ADVANTAGES
Generation of power without polluting the environment.
Simple construction, mature technology and easy maintenance.
No fuel transportation required.
No consumption of any fossil fuel which is non-renewable source of energy.
No external source is needed for power generation
CONCLUSION
In coming days, it will prove a great boon to the world, since it will save a lot of electricity of power plants that
gets wasted in illuminating the street lights. As the conventional source are depleting very fast, then it’s time to
think of alternatives. We got to save the power gained from the conventional sources for efficient use. So this
idea not only provides alternative but also adds to the economy of the country. Now vehicular traffic in big
cities is more, causing a problem to human being. But this vehicular traffic can be utilized for proper generation
by means of a new technique called “power hump”. It has advantages that it does not utilize any external source
[6].Now the time has come to put forte this type of innovative ideas, and also researches should be done to
upgrade its implication. In future, if the flywheel speed control device and voltage protection devices are added
with large generation process, it would be a model all over the world .After some modification of the designed
project, the efficiency of the whole system can be increased by increasing the capacity of the generator and
applying more weight.
