A water production system with a thermal separation device that defines a cold region and a hot region, a fluid-air heat exchanger located remotely from the thermal separation device and exposed to air, and a fluid circulation loop that thermally connects the cold region of the thermal separation device to the fluid-air heat exchanger so as to cool the fluid-air heat exchanger and condense water from ambient air to produce water pure enough so that with further treatment it can be made potable. Also disclosed are filtration and dispensing features that are appropriate for a potable water supply.
