Project UWash consists of converting the mechanical energy that goes into hand washing laundry into usable electricity. Our proof-of-concept system is composed of: an energy source (salad spinner), an energy harvester (AC generator), a regulating circuit (voltage regulator), a storage component (lithium ion batteries), and an application (charging an iPhone and USB based LED flashlight). The goal is to fully charge the LED flashlight after a one hour use and charge an iPhone to at least 50% after a 6 hour use. We were able to fully charge the flashlight in about 15 minutes but were only able to charge an iPhone to 41% after 8 hours of cranking with the AC generator. With the final UWash product we were able to power the flashlight for one and a half hours after a 15 minute use.
