1) The document describes a student project to design and fabricate a power generation system using speed breakers. Kinetic energy from passing vehicles would be converted to electrical energy through a roller mechanism connected to an electric generator. 2) The generated power could be used for streetlights and traffic signals, providing an alternative renewable energy source. Storing excess power in batteries could power lights at night. 3) Components of the system would include a flywheel, roller shaft, bearings, electric dynamo, and lithium-ion batteries to store generated power. Students will design, model, and test a prototype over several months.

- 2. Details of Project __________________________________________________________________ OBJECTIVE: In this project we will be fabricating technology to generate electricity from speed breakers in which the system used is reliable and this technique will help conserve our natural resources. The design of power generating speed breaker has concept of setting up a roller mechanism in the speed breakers which will be rotated by the moving vehicles due to friction .Its shaft will be connected to the electric dynamo and it will produce electrical energy proportional to traffic density. This generated power can be regulated for continuous supply. 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. . SCOPE OF WORK: ENERGY CONSERVATION & ECONOMY Electricity plays a very important role in our life”. Due to population explosion, the current power generation has become insufficient to fulfill our requirements. As a large amount of energy is wasted at the speed breakers through the dissipation of heat and also through friction, every time a vehicle passers over it. There is great possibility of tapping this energy and generating by making the speed-breaker as a power generation unit. In coming days, this 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 due to long transmissions. As the conventional sources are depleting very fast, it’s high time to think of alternative resources. We got to save the power gained from the conventional sources for efficient use. So this project not only provides alternative but also adds to the economy of the country. This way we can generate green, pollution-free alternative source of electricity, by the moving vehicles on the road. WORKING PRINCIPLE This project explains the mechanism of electricity generation from speed breakers. The friction force due to vehicle movement acted upon the speed breaker system will make the breaker move in opposite direction and the model will be having an Electro-kinetic energy conversion system which will be transforming this kinetic energy into electricity. The speed breaker arrangement will be having a protruded rollerat its top which will be having contact with the high frictional surface tires of the vehicle. The roller will be having its support

The power generating unit will be consisting of the fly wheel, dynamo, regulating circuit, battery, wires, diodes and other construction elements. The chain coming from roller will transmit the mechanical power of rotation from to roller to the flywheel. The flywheel will be further mechanically coupled to a generator of desired specifications as per the values of torque generated by the vehicle’s motion. This speed of flywheel is sufficient to rotate the rotor of a generator and is fed into the rotor of a generator. The rotor which rotates within a static magnetic stator cuts the magnetic flux surrounding it, thus producing the electric motive force (emf).This regulated emf is now sent to the storage battery where it is stored during the day time and can be used in night time for providing power to street lights. COMPONENTS TO BE USED FLY WHEEL: The primary function of flywheel is to act as an energy accumulator. It reduces the fluctuations in speed. It absorbs the energy when demand is less and release the same when it is required. ROLLER SHAFT: It is a rotating element, which is used to transmit power from one place to another place. It supports the rotating elements like gears and flywheels. It must have high torsional rigidity and lateral rigidity. SPRINGS: It is defined as an elastic body whose function is to distort when loaded and to recover its original shape when the load is removed. It cushions, absorbs or controls energy either due to shocks or due to vibrations. BEARINGS: A bearing is a device to allow constrained relative motion between two or more parts, typically rotation or linear movement. It permits relative motion between the contacting surfaces while carrying the loads. They reduce the friction and transmit the motion effectively. Bearings may be classified broadly according to the motions they allow and according to their principle of operation as well as by the directions of applied loads they can handle. The type of bearing used here is rolling element type bearing which is widely used, relatively high friction, suffers from station in some applications. Depending upon the application, lifetime can be higher or lower than rolling element bearings.
- 4. ELECTRIC DYNAMO: It is a device, which converts mechanical energy into electrical energy. Its work is based on “faraday’s laws of electromagnetic induction”. After the calculation of torque produced and the revolutions per minute , the voltage & current specifications will be decided and accordingly the desired dynamo will be installed into the system. BATTERY: A battery is a device that converts chemical energy contained within its active materials directly into electric energy by means of redox reaction. This type of reaction involves the transfer of electrons from one material to another via an electric circuit.For the purpose of lightning a street light for 12 hours we will use dry lithium-ion battery which will be charged from the power output of generator and will store the charge continuously. This stored current will be used in the night time for street lightening purpose.
