Abstracts: From low of energy conservation, we can say that energy neither be created nor be destroyed but it can be only change from one form to another form. So we can change the form of energy which during walking, running, throwing can utilize and produce useful work energy. At the stairs of colleges and buildings many people are used to walk so their motion can use as a form of energy. Here one mechanism is placed inside the stairs or road where many more people across. So when they across the stair than rack and pinion produce mechanical energy which is connected with one dynamo so electrical energy is produce and used for small purpose.
