The Pendulum Driven Electric Generator is an alternative indoor source of electricity that converts gravitational energy into electrical energy. As the pendulum arm swings through the presence of neodymium magnets the unit collects and stores the gravity and converted into electricity. The prototype can produce 8.4 watts per hour up to 201.6 Watts electricity in daily generation. Pendulum Driven Electric Generator is assembled with permanent magnet assembly, pendulum arm assembly, shaft and pulley belt system platform assembly, MPPT charge controller fixture assembly, power control box fixture assembly, battery housing assembly, generator fixture and the pendulum device cover assembly. The generator is a user-friendly machine as it can be easily placed at homes and offices in any climatic condition. The machine does not need any hazardous forms of fuel for generating electricity. Test results showed that the generator produces enough to generate electrical power during operation to charge up the battery bank. The machine was evaluated by a group of 25 experts using the TUP Evaluation Instrument for Prototypes. The unit was assessed “Excellent/Highly Acceptable” by the evaluators, which proves that it can generate electricity enough to charge electronic gadgets. The use fiber reinforced plastic and high power storage batteries are recommended. This implies that the prototype help to the prospective users to serve as an alternative indoor lighting and charging any electronic gadgets, and attained the desired end.
