Benefits of technology

[0006]Described herein is a passive technique for improving the efficiency of a wave-following, articulated raft wave-energy system. The motion-enhanced system is promising for the production of potable water for coastal communities and island communities.

Problems solved by technology

Because of its low efficiency, the Hagen-Cockerell raft system was never developed; while, the McCabe Wave Pump is now in the development stage.

[0013]The Articulate Barge Wave-Energy Conversion System

[0014]A computer-generated picture of an articulated barge system is shown in FIG. 1. In that figure, we see that the system preferably may be comprised of three barges of differing lengths. The forward barge 10 is the barge facing into the waves. The wave action causes the barge to rise and fall in a rotational fashion about the hinges 12 coupling this barge to the center barge 14. It has been found that this barge is capable of capturing approximately 60% of the incident wave energy. The relative rotational motions of the forward 10 and center 14

[0015]Barges excite the pumps 16 located over the hinges. These pumps 16 are preferably hydraulic pumps designed to draw in salt water, pre-filter the water and pump the water at high pressure to a reverse-osmosis (RO) desalination plant. Depending on the application and product water (potable water) requirements of the system, the RO can be on shore or on the deck of the after barge ...

Abstract

A wave-powered device having enhanced motion. The device including first, second, and third barges, with the second barge having a first reservoir and a second reservoir. The first and second reservoirs being coupled by a first passageway to permit a first fluid to selectively and passively move between the first and second reservoirs in a predetermined manner to increase the pitching moment of the second barge while the second barge pitches while floating over waves. A first coupling mechanism is coupled between the first and second barges to enable the first and second barges to move relative to one another, and a second coupling mechanism is coupled between the second and third barges to enable the second and third barges to move relative to one another.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of provisional U.S. Patent Application Ser. No. 60 / 740,674, entitled “Wave-Powered Energy Conversion System,” filed Nov. 30, 2005, which is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The utilization of ocean wave energy has been the goal of many for more than a century. There are primarily two products of wave energy conversion, those being electricity and potable water. Because electricity production is more “exciting” to humankind, most of the efforts in wave energy conversion have been focused on electricity. For those of us more interested in the benefit to humankind, potable water is more desirable. To realize this fact, the reader should answer the following two questions: (a) How long can I survive without electricity? (b) How long can I survive without water?[0004]2. Description of Related Art[0005]Of all of the wave energy te...
