Design And Construction Of Pedal Powered Electricity Generator

Abstract

This thesis presents the design, construction, and evaluation of a pedal-powered electricity generator aimed at providing a sustainable, low-cost, and human-centric energy solution for off-grid and rural communities. The system converts mechanical energy from pedaling into electrical energy using a DC generator, with output regulated and stored in a 6V battery. The design integrates bicycle components, a flywheel, charge controller, and monitoring tools to ensure efficient and stable power generation. Experimental results demonstrate a near-linear increase in voltage, current, and power with increasing pedal RPM, validating the theoretical underpinnings based on Faraday’s Law of Electromagnetic Induction. A maximum output of 0.218W was achieved at 79 RPM. The project also emphasizes affordability, portability, environmental benefits, and educational value, showing potential applications in emergency preparedness, fitness centers, and renewable energy education. Future enhancements include hybrid solar integration and IoT based performance monitoring.
