Abstract
An apparatus and method for generating electricity from ocean wave energy by using a floating device having a first portion that is movably coupled to a second portion. A hydraulic pump is coupled between these portions such that when the floating device is exposed to ocean wave energy, the hydraulic fluid within the pump is displaced. A flow rectifier is used to create a unidirectional hydraulic fluid flow that is dispensed through a rotary-vane pump which, in turn, is coupled to an electrical generator. Thus, as the rotary-vane pump is activated by the unidirectional hydraulic fluid flow, the rotary-vane pump turns the electrical generator for generating electricity. A plurality of hydraulic pumps and associated flow rectifiers, rotary-vane pumps and electrical generators can be coupled between the first and second portions. In addition, the floating device can include a third portion that is also movably coupled to the second portion and a plurality of hydraulic pumps and associated flow rectifiers, rotary-vane pumps and electrical generators can be coupled between the second and third portions.
