Ocean Pressure Electric Conversion
- Ocean Pressure Electric Conversion
Ocean Pressure Electric Conversion (OPEC) is an electricity generation and seawater desalination technology based on water pressure differences created by depth. It operates on the principle that the difference between water pressure at depth, or hydrostatic pressure, and normal atmospheric air pressure inside an enclosed and submerged Air-Water-Gravity generator device, or AWG, drives a linear piston electric generator. Portland, Oregon inventor, Richard Malcolm Dickson, invented both the OPEC concept and the AWG device. [ cite web

OPEC is a competitive way to generate clean, renewable hydroelectric power from oceans and deep lakes without external fuel input. It is superior to its main competitor, Ocean thermal energy conversion (OTEC), in cost, geographic limitations, and efficiency.Fact|date=April 2008 OTEC is limited to deep oceans in tropical latitudes where there is a large temperature differential from surface to depth, requires deep water, and averages about 10% efficiency.
A benefit of OPEC electric power production is desalination of seawater using reverse osmotic membranes.
