PURPOSE: To utilize and convert the water pressure energy stored at the deep portion of a water reservoir into the injection force, introduce it to a generator, and convert it to the electric energy.

CONSTITUTION: When a large amount of water is stored, the water pressure energy is stored at its deep portion. Water is injected toward a propeller from an injection port 5 by utilizing this water pressure energy, and the water repelled by the rotated propeller 2 hits a water turbine 1, its rotating force rotates a generator 4, thus enabling to generate electricity. In addition, the wind force in conjunction with the rotating movement of the front is fed to the rear for auxiliary activities and also enables ventilation through a ventilation pipe 6.
