  • Supplying breathable gas for underwater habitat
    Patent number: 6346141
    Abstract: A system and method are provided for supplying breathable gas to an underwater habitat submerged in water. A flow of respired gas that includes metabolically-produced carbon dioxide is extracted from the underwater habitat and mixed with water from the surrounding environment. As a result of such mixing, carbon dioxide in the respired gas is substantially absorbed by the water while a first gas is produced. Moisture in the first gas is filtered out to produce a breathable gas which is then introduced back into the underwater habitat.
