Abstract
A low-profile apparatus for converting water current into electricity. Fabric scoops are spaced along a continuous belt and, when submerged in a current of moving water, are pushed by the current thereby causing the continuous belt to move. The current pushes the fabric scoops downstream and then fold closed as the fabric scoops are rotated out of the water and travel back upstream. The moving continuous belt is used to turn an electric generator, which causes the apparatus to produce electrical energy. The apparatus includes one or more floats to support the continuous belt, electric generator, and other components of the apparatus. The apparatus can be moored or anchored in a variety of locations where there is moving water or currents. The apparatus maintains a low profile by using fabric scoops that collapse and fold flat when not submerged thereby reducing wind resistance and visible surface area above the waterline.
