Patent ID: 8164209

Claim:
An apparatus for creating internal directional underwater falls and generating electrical energy therefrom, comprising a hollow tank having a substantially vertical axis; a rotatable turbine located in an interior of said tank and having a horizontal axis; means providing a directional flow of water into said tank forming a directional underwater fall and directing the directional underwater fall onto blades of said turbine to rotate said turbine; an electrical generator connected with a shaft of said turbine so that a rotation of said shaft of said turbine is transmitted to said electrical generator which thereby generates electricity; and means for evacuating water from an interior of said tank after water passes through said turbine, wherein said means providing a directional flow of water include an opening provided in a top of said tank only at one side of said horizontal axis of said turbine so that said underwater fall acts exclusively on blades of said turbine and operates only in one part of the interior of said hollow tank at said one side, while another part of the interior of said hollow tank at another, opposite side of said horizontal axis of said turbine remains water free.
