Abstract: A motor having an upright shaft with vanes driven by different, simultaneous, multidirectional, generally horizontal currents, for ocean offshore or beach installation, the vertical height, measured by the operative vertical span of the vanes, being significantly much greater than any known prior art wave operated motors and representing the novel concept of simultaneous driving of the motor by wave or inflow currents as well as undertow or outflow currents impinging simultaneously on separate, vertically spaced groups of vanes.

Abstract: A wave motor is comprised of two or more parallel rotors having apertured radial paddle elements with hinged flaps or blades covering the apertures such that upon the impingement of water upon one side of the paddles the blades cover the apertures and the wheel is turned, but upon impingement of water against the other side of the paddles the blades swing open. Each pair of rotors are coaxially mounted and designed for rotation in opposite directions to maximize extracted power regardless of the predominant current direction, and a single take off shaft is coupled to the rotors through a ratchet and gear mechanism.
