Abstract

The ever-increasing demand for electrical energy drives the development of human-powered alternative energy conversion technologies to operate DC generators. However, inconsistent human-generated rotation leads to fluctuations in voltage, current, and power output. This study aimed to design a mechanical energy conversion system prototype utilizing a flywheel, a spring-crankshaft mechanism, a freewheel gear, and a crank to drive a 24V 30W DC generator. Employing Research and Development (R&D) and experimental methods, the test results demonstrated significant improvements following the addition of the freewheel gear and crank. Flywheel speed increased from 751.7 rpm to 2,018 rpm (168.5%), generator speed from 1,170.6 rpm to 3,503 rpm (199.3%), voltage from 2.19 V to 3.44 V (57.1%), current from 0.091 A to 0.144 A (58.2%), and power from 0.205 W to 0.501 W (144.4%). Although effective at enhancing energy delivery, the actual conversion efficiency remained low (0.41%–0.45%) due to mechanical transmission losses.
