3. INTRODUCTION Nowadays energy and power are the one of the basic necessities regarding this modern world. As the demand of energy is increasing day by day, so the ultimate solution to deal with these sorts of problems is just to implement the renewable sources of energy. But these renewable energy sources must have to be adopted in practical manner by keeping an eye on all aspects regarding the research work. So then these techniques should be applied in order to get the desired output.

4. The objective of this work is power generation through footsteps as a source of renewable energy that we can obtained while walking on to the certain arrangements like footpaths, stairs, plate forms and these systems can be install elsewhere specially in the dense populated areas. In this project we are generating electrical power as non-conventional method by simply running on the train in the foot step. Non-conventional energy system is very essential at this time to our nation. Non-conventional energy using stair case needs no fuel input power to generate the output of the electrical power. This project using simple drive mechanism such as rock and pinion assemble and chain drive mechanism.

5. For this project the conversion of the force energy in to electrical energy. The control mechanism carries the rack & pinion, D.C generator, battery and inverter control. We have discussed the various applications and further extension also. So this project is implemented to all foot step, the power generation is very high.

6. NEED FOR NON-CONVENTIONAL ENERGY Fuel deposit in the will soon deplete by the end of 2020. Fuel scarcity will be maximum. Country like India may not have the chance to use petroleum products. Keeping this dangerous situation in mind we tried to make use of non-pollutant natural resource of petrol energy. The creation of new source of perennial environmentally acceptable, low cost electrical energy as a replacement for energy from rapidly depleting resources of fossil fuels is the fundamental need for the survival of mankind. We have only about 25 years of oil reserves and 75 – 100 years of coal reserves. Resort to measure beginning of coal in thermal electric stations to serve the population would result in global elemental change in leading to worldwide drought and decertification.

7. Problem statement To design and develop the model showing the concept of Stair case power generation. Also to fabricate the model of the same which would able to show the characteristics of the systems and working according to need.

8. objective To design and develop the model of Stair case power generation. Also fabricate the model which will work on the systems for required application. To harvest the energy which will be wasted. To help people to avoid problems such as energy scarcity , etc.

9. Literature review 1. An Investigation on Generation of Electricity Using Foot Step Siba brata Mohanty , Sasank shekhar Panda   The proposed setup involves number of simple setup that is installed under the walking platform. When people walk on this platform their body weight compresses the setup which rotates a dynamo or Sanyo coil and current produced is stored in dry battery. To reduce the external compression, a responsive sub-flooring system is installed. And while the power producing platform is over crowded with moving population, energy is produced at larger levels. Greater movement of people will generate more energy.

10. Electromagnetic Stair case Power Generation Alla Chandra Sekhar , B Murali Kishore, T Jogi Raju The main aim of this project is to develop much cleaner cost effective way of power generation method, which in turns helps to bring down the global warming as well as reduce the power shortages. In this project the conversion of the force energy in to electrical energy by using electromagnetic induction. In this project the force energy is converted into electrical energy. The control mechanism carries the copper coil and bar magnetic which is used to generate voltage, a rechargeable battery is used to store this generated voltage .

11. Electricity Generation from Footsteps; A Regenerative Energy Resource Tom Jose V, Binoy Boban , Sijo M T A slab of concrete harnesses kinetic energy whenever it is stepped on. This energy, created by 5 millimeters of flex in the material, is then either stored by lithium polymer batteries contained within the slabs or transmitted immediately to streetlights or other electronics located close by. The current model, made from stainless steel, recycled car tires and recycled aluminum, also includes a lamp embedded in the pavement that lights up every time a step is converted into energy (using only 5 percent of the generated energy).

12. Construction The complete diagram of the power generation using STAIR CASE is given below. L-shapes window is inclined in certain small angle which is used to generate the power. The pushing power is converted into electrical energy by proper driving arrangement. The rack & pinion, spring arrangement is fixed at the STAIR CASE which is mounded bellow the L-shapes window. The spring is used to return the inclined L-shapes window in same position by releasing the load.

13. The gear wheel is coupled to the smaller motor shaft. The generator is used here, is permanent magnet D.C generator. The battery is connected to the inverter. This inverter is used to convert the 12 Volt D.C to the 230 Volt A.C. This 230 Volt A.C voltage is used to activate the light, fan and etc.   By increasing the capacity of battery and inverter circuit, the power rating is increased. This arrangement is fitted in FOOT STEPs; the complete arrangement is kept inside the floor level except the pushing arrangement.

14. working In this project a gear system is attached with flywheel which causes to rotate the dynamo as the tile on the deck is pressed The power that is created is saved in the batteries In addition we will be able to monitor and control the amount of electricity generated. When an individual passes it push the tile on the ground surface which turn the shaft beneath the tile, turn is limited by clutch bearing which is underpinned by holders. Primary shaft is rotate approx. twice by a single tile push.

15. The movement of the prevailing shaft turn the gear which builds it 15 times (1:15) then its movement which is temporary store the movement, which is convey to the DC generator ( it generates 12V 40 amp at 1000 rpm). Energy generated is stored in the batteries , an inverter circuitry is implemented to convert the DC to AC ,so that we can sprint the home electrical load , Further a microcontroller based home mechanization framework is implemented which control rooms prudently. Entire framework is put on the iron bars called channels. Our entire project physical system diagram is shown in following.

17. Project schematic We consider approximate deflection of 75mm

18. Description of components The Proposed system consist of the following main components: 1. MS plate 2. MS Pipes 3. Rack and pinion 4. DC motor 5. STAIR FRAME 6. LED lights Etc.

19. M.s. plate The Mild steel plate is a square plate of size 1feet*1 feet i.e. 300 mm*300 mm. The thickness of the plate is 3mm. We are using two plates here one base plate and one upper plate to place foot.

20. Rack and pinion A rack and pinion is a type of linear actuator that comprises a pair of gears which convert rotational motion into linear motion. The circular pinion engages teeth on a linear "gear" bar – the rack. Rotational motion applied to the pinion will cause the rack to move to the side, up to the limit of its travel. For example, in a rack railway, the rotation of a pinion mounted on a locomotive or a railcar engages a rack between the rails and pulls a train along a steep slope.

21. Dc motor D.C. machines are the electro mechanical energy converters which work from a DC source and generate mechanical power or convert mechanical power into a DC power . A DC Geared DC motor is a simple DC motor with gear box attached to the shaft of the motor which is mechanically commutated electric motor powered from direct current (DC).

22. SPRINGS A spring is defined as an elastic body, whose function is to distort when loaded and to recover its original shape when the load is removed. The various important applications of springs are as follows : 1. To cushion, absorb or control energy due to either shock or vibration as in car springs, railway buffers, air-craft landing gears, shock absorbers and vibration dampers. 2. To apply forces, as in brakes, clutches and spring loaded valves. 3. To control motion by maintaining contact between two elements as in cams and followers. 4. To measure forces, as in spring balances and engine indicators. 5. To store energy, as in watches, toys, etc .

23. Extension springs are attached at both ends of the components. When the stair moves down due to body force , the spring retracts to move the stair at its original position. Extension spring absorbs and store energy as well as creates a resistance to a pulling force.

26. applications Applications of the stair case power generation are, This can be implemented on railway station to generate electric power. In bus station. In car parking system. In Airports. In Lift system. In car lifting system. In street lights Electric escalators

27. Future scope We can use this principal in the speed breakers at high ways, where the vehicles rush too much, thus increase input torque and ultimate output of generator. By increasing the size and multiplying the frequency of array of system we can build a big power option for domestic and public use. If we use this project at very busy stairs, then we produce efficient useful electrical energy for large purposes. The design of the project can be further modified for commercial and large scale use.

28. Conclusion In concluding the words of our project, since the power generation using stair case get its energy requirements from the Non-renewable source of energy. There is no need of power from the mains and there is less pollution in this source of energy. It is very useful to the places all roads and as well as all kind of stair case which is used to generate the non-conventional energy like electricity.
