Abstract— We are using the non-renewable energy sources such as petroleum as well as renewable sources like solar, wind, tidal power etc., but still we couldn’t overcome our power needs. So we have to generate electricity through each and every possible ways. Power can be generated through we are stepping on the stairs; the generated power will be stored and can be used for domestic purposes. This system can be installed at homes, colleges, railway stations, where the people move around the clock. The utilization of waste energy of human foot power is very much relevant and important for populated countries like India and China. A special mechanical arrangement such as crankshaft mechanism is employed on the stair case. This arrangement will convert the foot power applied on stairs, as a rotary motion. This rotary motion will be used to generate efficient electricity. It’s an eco-friendly; easily accessible and non-conventional power generation system when compared to existing systems.
INTRODUCTION
This project attempts to show how energy can be tapped and used at a commonly used floor steps. The usage of steps in every building is increasing day by day, since even every small building has some floors. A large amount of energy is wasted when we are stepping on the floors by the dissipation of heat and friction, every time a man steps up using stairs. There is great possibility of tapping this energy and generating power by making every staircase as a power generation unit. The generated power can be stored by batteries, and it will be used for lighting the building.
SCOPE OF THE PAPER
The utilization of energy is an indication of the growth of a nation. For example, the per capita energy consumption in USA is 9000 KWh (Kilo Watt hour) per year, whereas the consumption in India is 1200 KWh (Kilo Watt hour). We can say that to be materially rich and prosperous, a human being needs to consume more and more energy.
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.
In India, unlike the developed countries we do not have elevators or lifts in the buildings of rural area. There are still conventional steps are used for steps on the floor. From our point, the energy can be utilized by just placing a unit “Staircase Power Generation system”. By placing this system in a rural building or in places like railway stations, so much of energy can be tapped. This consumed energy can be used for the lights on the rural area or the crowded places like railway stations, colleges etc
III. WORKING PRINCIPLE
This project is concerned with generation of electricity from ‘power step’ set up. The human load acts upon the
Power step-setup will produce linear reciprocating motion on the power step. Here the reciprocating motion of the power step is converted into rotary motion using the crankshaft arrangement. A flywheel is used to produce rotary motion. The flywheel and the power step pedal are connected by means of connecting rod. The rotary motion of large flywheel is given to the small pulley by belt or chain. Hence the speed that is available at the flywheel is relatively multiplied by the rotation of the smaller pulley.
This speed is sufficient to rotate the rotor of a 12V generator. The rotor which rotates within a static magnetic
stator cuts the magnetic flux surrounding it, thus producing the electro motive force (emf). This generated emf is then sent to an inverter, where the generated emf is regulated. This regulated emf is now sent to the storage battery where it is stored. This current is then used for other purposes.
The generator converts the mechanical rotary motion into electrical energy.
IV. CONSTRUCTION
The following arrangements are made to make it as a good energy transfer system.
A. Stationary Plate:
It is a base plate which is connected to other rigid RCC steps and it provides operating platform for the moving power step by means of bearing support
