Gravity Battery: Storing Electrical Energy In The Form Of Gravitational Potential Energy

A low budget device is designed that is capable of harnessing energy from an object falling under gravity. Object is suspended from the device, through a high strength nylon thread, placed at a certain height. 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. This device uses mechanical energy produced by a human and converts it into gravitational potential energy that is later converted into electrical energy. 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. The device can be used as mechanical battery as well and has the potential to replace the use of chemical batteries used in solar street lights. The prototype built is ready for on-field applications.
