The patent relates to a closed thermal power system ideally suited for submersibles which includes an internal combustion engine or turbine connected to feed its exhaust gases to a water cooled condenser for condensing and purging water from the system. A cryogenic source of liquid oxygen receives the gases and carbon dioxide is sublimated to the solid state and stored at low pressure. As carbon dioxide is cooled, oxygen is boiled off and fed to the engine where it is mixed with fuel and recycled portions of the exhaust gases.
