Recovery of useful energy from lost human power in gymnasium

Human powered gyms are ones in which equipment can be used to generate electricity. Since the concept of a green or sustainable gym is recent, the potential of cardio equipment like treadmills, stationary bikes and rowing machines in generating energy are discussed in this paper. The power generated in a typical human powered gym, based on the equipment already existing in the market is analyzed. The amount of carbon dioxide emissions saved and the payback period for implementing this gym are also estimated. A survey was carried out to better understand how people would react to the presence of such gym. It was found that the energy-producing equipment in the gym not only benefit environmentally but also economically in the long run.
