Abstract
An apparatus for generating electricity using water flow in a body of water comprises: an array of spaced apart elements. Each element defines an elongate flow passage and has an upstream side and an elongate downstream side, each element being provided with a series of holes spaced along its length and the downstream side extending and tapering away in the direction of flow. The elements are arranged side by side such that opposing walls of adjacent elements define a venturi section and a first diffuser section extending downstream from the venturi section. The apparatus also comprises:—a flow conduit having an inlet and an outlet;—a turbine located in the flow conduit;—and a generator connected to the turbine; The flow passages are connected to the outlet of the flow conduit such that the flow of water through the venturi sections causes water to be drawn through the flow conduit out via the holes the resulting flow driving the turbine.
