ABSTRACT:
A device for delivering purified water from a reservoir of salt water including a vapor tube supported concentrically inside a barrier tube The vapor tube has apertures that provide a passage of purified condensate from interior of the purified waste to the space between the space between the outside of the vapor tube and the inside of the barrier tube. A pump between the reservoir of salt water and the interior of the vapor tube generates a pressure differential that forces water vapor from the surface of salt water to the inside of the vapor tube. Condensate inside the vapor tube flows as fresh water to outside the vapor tube.
