Dragon Breath: Rebreather with Passive Heating
Abstract
JHU/APL proposes the development of a CO2 scrubber that is worn as a vest inside the dry suit. Combined with an oxygen source, the novel rebreather passively heats the diver in cold environments. By eliminating convective heating loss and generating exotherms from CO2 and H2O capture, the vest will net 57 W of heat to the diver. The value approximately doubles under exertion. Significantly, the passive heating from Dragon Breath will reduce the need for active heating on dives in cold water. It might therefore result in weight and volume savings from smaller active heat sources, or it could extend the duration of the mission.
