e/Ocean pressure electric conversion

Information
has gloss	eng: Ocean pressure electric conversion 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.
