                       The appropriate technology is recognizing need of local people, meeting their aspirations and bringing them one step closer to energy access. There is flow of water from higher hills to lower plains. Here gravity does most of the work. The Kinetic energy of water can be directly used for generating energy. Traditionally we have been harnessing such energy through water mill. Still today lots of people in rural areas are highly dependent on traditional water mill for grinding all required household goods such as flour, rice, wheat, spices and also oil in some cases.
