Patent ID: 8866321

Claim:
An apparatus for generating electricity from ocean wave energy, said apparatus comprising: a floating device having a first portion movably coupled to a second portion; at least one bi-directional hydraulic pump coupled between said first portion and said second portion, said bi-directional hydraulic pump driving a hydraulic fluid whenever said first portion moves with respect to said second portion due to ocean wave energy, said at least one bi-directional hydraulic pump driving the hydraulic fluid in a first flow direction when said bi-directional pump moves in a first pump direction and driving the hydraulic fluid in a second flow direction, opposite said first flow direction, when said at least one bi-directional pump moves in a second pump direction, opposite said first pump direction; a fluid rectifier, in fluid communication with said at least one bi-directional hydraulic pump, said fluid rectifier generating a unidirectional hydraulic fluid flow from the hydraulic fluid driven in said opposite first and second flow directions generated by said at least one bi-directional pump's opposite motions in said first and second pump, said fluid rectifier comprising a housing separate from said at least one bi-directional hydraulic pump; a rotary vane pump, coupled to said fluid rectifier, that uses said unidirectional flow to generate a rotational motion via a drive member; and a rotating electrical generator that is coupled to said drive member, said drive member causing said rotating electrical generator to generate electricity when said drive member is rotating.
