Abstract:
1. A watercraft for producing purified water, said watercraft comprising: a passive reverse osmosis subsystem comprising a saline water inlet, a saline water outlet fluidly downstream of said inlet and a membrane disposed fluidly between said inlet and said outlet and configured to allow preferential passage of water relative to salt in a saline water supply passed therethrough; a submergible water container in fluid communication with said reverse osmosis subsystem to receive purified water that has passed through said membrane, said submergible water container defining an evacuatable region such that a vacuum may be selectively formed therein; a passive dehumidification subsystem configured to use said purified water in order to condense at least a portion of water contained in an ambient air supply that comes in thermal contact with said purified water present in said passive dehumidification subsystem; at least one purified water storage tank configured to receive said purified water from said submergible water container and said condensed water from said dehumidification subsystem; and a hull for supporting said reverse osmosis subsystem, said submergible water container, said dehumidification subsystem and said at least one tank.
