ABSTRACT-
Pedal operated energy generator is a device that utilises human energy to produce electricity to charge battery. The design was originally conceived to meet the energy needs of those living in rural areas. Our study focused on the design and fabrication of pedal operated power generator with an intention of exercising while generating electricity Here a generator is used to generate electricity. The generator is coupled to a pulley which is rotated by a belt and chain sprocket system of a bicycle structure. The input power is given to the paddle and final rotational speed is achieved in the generator rotor. Most components of the pedal power generator are based upon existing inventions, both recent and historic. This research brings together the fecundity of pedal power generation with exercising feasibility thus helping towards wellbeing. The integrated unit will generate needed electricity in situ, and transport it to the site with pedal power. We think our project will inspire students and the public to think about the realities of exercising, energy utilization and production which may spark new solution. In many countries it can be used in rural and urban areas as a useful source of energy for conjugal family where the family members can itself charge the device for a short period of time or in public places such as parks and playgrounds where one can pedal and charge their electronic device in unison. This will not only produce electricity when needed but also an alternate way of physical exercise for them. Due to the low cost and maintenance, extensive use of this application of ‘Paddle Powered Generator’ can be a suitable source of free energy. Electronic devices such as mobiles, laptops have a 12 V battery. These devices have become very effective tool in modern world mode of communication in developing countries or least developed countries (LDCs), it is easily available. But the problem arises on how to charge a mobile phone when the local power system is not available. The project was designed to be cheap, simple, durable, portable and easily be maintained. It was fabricated using nearby materials. The purpose of this project is to efficiently transfer human power to develop a pedal power battery charger system.
INTRODUCTION-
The Pedal operated power generation utilizes human energy to produce electricity quickly and efficiently. This energy can be harness by using human efforts through the movement of human feet and hands in some cases for the generation of electricity. The use of pedal power also used for leg exercise and reduces the stiffness of the muscles.Theuseofpedalpowerdevelopedoveratimeperiod.

Pedal power is the source of getting energy from human beings. It can be explain as the transfer of energy generated through pedal operation using the movement of humanfeetandhands Theuseofpedalpoweralsostrengthsthemuscles.
