Indigenous communities in rural Viet Nam, such as the Muong, often lack any form of power generation. This provides them with little opportunity to undertake practical and income-generating activities after nightfall. Recently, however, the Muong have adopted a form of hydropower, known as pico-hydro – the smallest scale of hydropower system. The kinetic power of moving water is transformed into electrical power by a turbine and generator. This gives the community valuable light in the evening and the ability to explore new technological avenues.
