Abstract
Abstract An apparatus for producing electrical energy from multidirectional water wave action including a central support for placement on the bottom of a body of water with the support extending vertically above the surface of the water. A multiplicity of shafts extend radially and horizontally from the central support. A multiplicity of floats are supplied for each shaft with an elongated member connected at the upper end to each float and in engagement with a weight connected to the lower end of each elongated member and extending below the shaft. A one way clutch is mounted on each of said shafts and associated with each of said elongated members intermediate the ends thereof adapted to rotate each shaft in one direction when the float raises on a wave and not affect the shafts when said floats lower in a trough between waves. Each of said shafts is connected to electrical generating means for actuation of the same.
