In this project a low budget and an eco-friendly device is designed which is capable of harnessing energy from an object falling under gravity. Object is suspended from the device through a high strength nylon thread. Gravitational potential energy of an object placed at a certain height is converted in to kinetic energy. As the object descends it rotates the wheel which is coupled with gear train. This gear train further rotates the pinion that is mounted on the generator shaft. An electrical output is produced at the armature terminals of the generator which is sufficient for various applications. Since almost all the renewable sources of energy have limited application due to their operational condition, this device can be used anywhere on earth irrespective of location, weather conditions, time and fuel. Gravity can be said as the fuel to drive the device. The prototype built is ready for on-field applications.
