Abstract: This invention is developed using all the laws of hydraulics and fluid dynamics by digging a tunnel, placing a pipe, etc in the earth surrounding the water body at various levels at least starting from the surface of the water body and going to the very bottom of the water bed in various geometrical figures, angles and degrees suitable for an individual project and individual site and individual generation requirements any where in the world for the water to come out of the water body either from the bottom, below the bottom of the water bed and projecting into the water body or from the sides surrounding the water body and run into the facility from the inlet and various inlets which is constructed below the main level of the water body or mean sea level or main water body level on the earth and required in the water body also so that the various turbine-generators of various capacities, shapes, designs, available in the global markets are erected in a cascading manner or any other system designed for the ge
