This invention is designed to create potentially unlimited commercial fresh water at a significantly reduced cost in relation to existing fresh water creation systems such as sea water desalination. This invention pumps coastal atmospheric air through sealed pipes to ocean water depths (ideally) of approximately 100-305 meters, or (ideally) into the local ocean's thermocline layer. Fresh water condensation occurs inside the sealed air pipes as cold ocean water chills the outside of the pipes. Condensation fresh water flows via gravity to the low point in the sealed air pipes where a powered fresh water pump is located. This powered fresh water pump then pumps the accumulated condensation water to the ocean surface and then on to shore as usable fresh water. The pumped-in air, now dehumidified, is piped to the surface and returned to the atmosphere.
