The purpose of the project was to provide electricity that was sufficient for powering lights and charging cell phones in rainy locations with limited electricity access. A household rainwater energy harvesting system was designed, prototyped, and tested to determine the feasibility of rainwater as a source of renewable energy. The system produced a power of 0.74 Watts and a 14.8% efficiency at 8 GPM. When scaled for a month with higher intensity of rainfall the current system could charge about 1.8 cell phones. This project proved the concept of a rainwater energy harvesting system. The system could be combined with a filtration system and holding tank to collect drinkable water so that the system serves a dual purpose for people with limited access to electricity and water.
