Electric Power Generation Using Foot Step Method Synopsis: In this project We are generating electrical power as non_conventional method by simply walking or running on the foot step. Non-conventional energy system is very essential at this time to our nation. Non-Conventional energy using foot step needs no 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. For this project the conversion of the force energy is converted into electrical energy. The control mechanismcarries the rack and pinion, D.C geberator, battery and invertor control. We have discussed the various applications and further extensions also. Introduction: Man has needed the used enery at an increasing rate for his sustenance and welll being ever since he came on the earth a few millliion years ago. Primitive man required energy primarily in the form of food. He derived this by eating plants or animals, Which he hunted. Subsequently he discovered fore and his energy needs increased as he started to make use of wood and other bio mass to supply the energy needs for cooking as well as for akeeping himself warm. With the passage of time, man started to cultivate land for agriculture. He added a new dimension to the use of energyby domesticating and training animals to work for him.
With further demand for energy, man began to use thewind for sailing ships and for driving windmills, and theforce of fa1ling water to turn water for sailing ships andfor driving windmills, and the force of falling water to turnwater wheels. Till this time, it would not be wrong to saythat the sun was supplying all the energy needs of maneither directly or indirectly and that man was using onlyrenewable sources of energy.WORKING PRINCIPLE The complete diagram of the foot step powergeneration is given below. Only one step is inclined incertain small angle which is used to generate the power.The pushing power is converted into electrical energy byproper driving arrangement. The rack & pinion, springarrangement is fixed at the inclined step. The spring isused to return the inclined step in same position byreleasing the load. The pinion shaft is connected to thesupporter by end bearings as shown in fig. The larger.sprocket also coupled with the pinion shaft, so that it isrunning the same speed of pinion. The larger sprocket iscoupled to the small cycle sprocket with the help of chain(cycle). This larger sprocket is used to transfer therotation force to the smaller sprocket. The smallersprocket is running same direction for the forward andreverse direction of rotational movement of the largersprocket. This action locks like a cycle pedaling action. The fly wheel and gear wheel is also coupled to thesmaller sprocket shaft. The flywheel is used to increasethe rpm of the smaller sprocket shaft. The gear wheel iscoupled to the generator shaft with the help of anothergear wheel. The generator is used here, is permanent
magnet D.C Stepper Motor. The generated voltage is12Volt D.C. This voltage is further amplified using ICMC34063 DC-DC convertor and is stored to the Lead-acid12 Volt battery. The battery is connected to the inverter. Thisinverter is used to convert the 12 Volt D.C to the 230 VoltA.C. This working principle is already explained the abovechapter. This 230 Volt A.C voltage is used to activate thelight, fan and etc. By increasing the capacity of batteryand inverter circuit, the power rating is increased. Thisarrangement is fitted in shopping complex, college andwherever the large people walking on the foot stepssimultaneously.ADVANTAGESPower generation is simply walking on the stepPower also generated by running or exercising on thestep.No need fuel inputThis is a Non-conventional systemBattery is used to store the generated powerAPPLICATIONSPower generation using foot step can be used in most ofthe places such as 1. Colleges, 2. Schools, 3. Cinema theatres, 4. Shopping complex 5. Railway stations 6. Airports
