Project UWash

The Battery Charging Hand-Powered Washing Machine

The UWash is designed for those with the least income living in the poorest nations who do not have easy access to water or electricity. The UWash converts the mechanical energy needed to wash laundry, provided by a salad spinner, into electrical energy with the use of an AC generator. The output voltage of the generator is regulated in order to charge a commercial USB based power bank equipped with lithium ion batteries. The output of the charger can then be used to charge an iPhone or portable LED flashlight through a USB cable. Figures 1 and 2 below show the side an top view of the project respectively.
