Eco-friendly power generator cum fitness analyzer

Abstract

The modern challenge faced with the global energy situation is the growing energy demand and the strong dependence on unsustainable fossil fuels. Another concurrent issue is the adverse health and socio-economic implications of adult obesity. Human Power Generation, which uses metabolized human energy to generate electrical power, could potentially address both these challenges. This paper discusses design and development of a method of exercising on a bicycle to convert the mechanical rotational power of human peddling to useable electrical energy using a dynamo integrated charge controller that charges a battery. Also, during exercising the health parameters such as body temperature and heart rate are reliably monitored using wearable sensors and wireless embedded processer to analyze the fitness level of a person and issue health alarm to prevent mishap during exercising. Further, the data is wirelessly transmitted to remote user interface for monitoring, logging and analyzing the electrical power generation capabilities of a person along with health condition. Experimental proven results indicate that system is capable to generate electrical energy during cycling by young humans with typical average efficiency of 17% or more. The system model is a smart power-generating exercising mechanism that is attractive and effective to be used in homes, gyms, health clubs and other extraterrestrial environments as a source of low cost sustainable green energy cum fitness analyzer.
