Design and Fabrication of a Pedal Operated Power Generator
Energy conservation is a topical issue and this design proffered an efficient method of doing so. The design was originally conceived to meet the energy needs of those living in rural areas, due to poor access to electricity and also as a model for gym centers and cycle workout studios. Most persons living in these rural areas possess at least a cell phone but lack the means to charge them. This study focused on the design and fabrication of a pedal operated power generator, for the intents of burning fats while yet generating electricity. The power generator was designed to be simple, cheap, durable and easily maintained. It was fabricated using locally sourced materials and is intended to encourage local ingenuity and empower aspiring entrepreneurs especially in developing countries. Its purpose is to efficiently transfer human foot motion less than 60 rpm via a treadle and sprocket chain step up to drive a 24V DC permanent magnet generator. The inverter converts the direct current (DC) into alternating current (AC) which is needed to charge low voltage devices like mobile phones, laptops etc. Upon completion, it was found to produce a voltage of 15V and 2.5A at a speed of 483rpm generator speed. The overall efficiency of the system was about 66.6% Keywords Energy, pedal, generator, inverter, diode
