Water mill technology has existed in the Himalayan region for centuries. Called a ghatta in Nepal and a gharat in India, these mills are used to grind corn, wheat, and other grains for the local agricultural community.

The aim of this study is to engineer a way to harness the rotational energy of the traditional mill and transform a ghatta into a community battery charging station. Such a renewable energy source has the potential to bring electrical lighting to the many parts of the Himalayas that remain unelectrified.
