METHOD AND SYSTEM FOR PRESSURE HARVESTING FOR UNDERWATER UNMANNED VEHICLES

摘要

An underwater vehicle includes systems for harvesting ambient hydrostatic pressure and storing the same as a gas pressure in a compressed gas system and as a water pressure in a pressurized electrolysis system. The gas pressure is used to perform mechanical work or to generate electrical power via a prime mover. The water pressure is used to release pressurized hydrogen and oxygen gases via electrolysis. The pressurized hydrogen and oxygen gases are used in a combustion chamber to generate propulsion power for the underwater vehicle.
