Abstracts: A water pumping windmill which can be built largely with materials and skills available in rural areas has been designed and fabricated. The windmill uses a rotor and incorporates a novel sail-type construction.The pump is of positive displacement type using the casing of a pneumatic type for the pumping chamber.Two prototypes have been constructed and these have indicated a reasonable performance and reliability.By using water pumping windmill we can deliver water at some height and because of non-convential energy sources we can save energy
