More About HPG

The Human Power Generation (HPG) team is an undergraduate research project that focuses on harnessing the human power easily found in fitness facilities, namely at the Recreational Sports Facility (RSF) at University of California, Berkeley. We aim to convert the exerted energy during exercise into electrical energy that may be used as an alternative power source. Research shows that continuous use of the 28 elliptical exercise machines at the RSF can harness approximately 10,000 kWh over a year. Although this energy amounts only to 0.78% of the RSF’s total energy needs, it is valuable nonetheless.
