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 water container in fluid communication with said reverse osmosis subsystem to receive purified water that has passed through said membrane; a passive dehumidification subsystem comprising an air capture device that is in heat exchange communication with said water container to use said purified water there in order to at least partially condense water contained in an ambient air supply that comes in contact with said air capture device; at least one purified water storage tank fluidly coupled to said water container and said dehumidification subsystem such that purified water resident in each can be conveyed to said at least one tank; and a ship onto which said reverse osmosis subsystem, said water container, said dehumidification subsystem and said at least one tank are mounted.
