    Abstract: Apparatus for converting the energy present in water currents into electrical energy includes a rotatable central shaft a portion which is submerged below the surface of a body of water. A multiplicity of curved, horn shaped, devices responsive to water currents are connected via arms to the central shaft and cause the arms and the shaft to rotate and drive an electrical generator to produce an electrical output. The central shaft may be coupled to an electrical generator located above the water level to permit the easy and reliable maintenance of the apparatus. Alternatively, the central shaft may be coupled to a submersible electric generator or may extend horizontally parallel to the floor of the body of water.
