DESIGN AND CONSTRUCTION OF A SPRING-POWERED GENERATOR

ABSTRACT The Spring-Powered Generator presents an innovative, cost-effective, and sustainable alternative to conventional power generation methods, particularly in regions with unreliable electricity supply. This project focuses on designing and constructing a generator that harnesses mechanical energy stored in tensioned springs, converting it into rotational motion to drive a 3.5KW alternator via a flywheel and pulley system. Unlike fuel-powered generators that rely on expensive and environmentally harmful fossil fuels, this system offers a clean, low-maintenance, and locally adaptable solution for small-scale energy needs. The methodology involved selecting high-tension springs for energy storage, optimizing a flywheel for consistent motion, and designing a pulley system for efficient power transmission. An electric motor assists in rewinding the springs, ensuring continuous operation. Performance evaluations, including mechanical and electrical calculations, validated the system’s potential, though limitations in spring availability affected full implementation. Despite challenges, the Spring-Powered Generator demonstrates the feasibility of using stored mechanical energy for electricity generation, providing a practical alternative for rural households, small businesses, and off-grid communities. With further development and material improvements, this technology could significantly reduce reliance on fossil fuels, lower energy costs, and contribute to Nigeria’s sustainable energy goals.
