Design and Construction of Flywheel Fuel-Less Generator

The flywheel fuel-less generator is a flywheel energy storage system (FESS), which has attracted new research attention recently in applications like power quality, regenerative braking and uninterruptible power supply (UPS). As a sustainable energy storage method, flywheel energy storage has become a direct substitute for batteries in UPS and other electrical applications. The flywheel energy storage system is also known to act as a fuel-less generator working under the original idea of Chas Campbell, as further explained by Lee Tseung's lead-out theory. This project work however, presents an overview of the applications of FESS in power system and microgrid (MG), and also analyses the design parameters in order to improve the energy density of the fuel-less generator. The aim is to improve its value and enhance its applications in numerous fields such as renewable power generation and practical demonstration of the dynamics of flywheels to undergraduates. At the end of the project work, it was discovered that the flywheel energy storage system (the fuel-less generator), possessed a great power density (983.4kw/kg), capable of producing 3.5kw of electricity supply, although its energy density intensity (3.71kwh/kg) remains minimal, it however cripples it sustainability. The machine was also found out to be 75.9% efficient. From the research and results, certain parameters such as increasing the flywheel's energy density have been discovered to enhance the machine's sustainability. Thus, if these parameters are carefully implemented on the subsequent related works, we can tend towards achieving the self-sustainability and greater efficiency of the fuel-less generator using flywheel.
