TLDR
In this paper, a method for extracting drinking water from moisture-laden air at atmospheric temperature through the use of a heat exchanger at or near subsurface temperature which is in air communication with the atmosphere for allowing atmospheric moisture-laced air to enter, pass through, cool, arrive at its dew point, allow the moisture in the air to precipitate out, and allow air to pass outward to the atmosphere again.Abstract:
Apparatus and method for extracting potable water are disclosed in preferred form as extracting drinking water from moisture-laden air at atmospheric temperature through the use of a heat exchanger at or near subsurface temperature which is in air communication with the atmosphere for allowing atmospheric moisture-laden air to enter, pass through, cool, arrive at its dew point, allow the moisture in the air to precipitate out, and allow the air to pass outward to the atmosphere again. Suitable apparatus may be provided to restrict air flow and allow sufficient residence time of the air in the heat exchanger to allow sufficient precipitation. Further, filtration may be provided on the air input and a means for creating a movement pressure, in the preferred form of a turbine, may be provided on the output. The water from the system of the present invention may then be collected and provided for human consumption in conventional manner.read more

TL;DR: A liquid separation purification system applicable to extracting purified liquids from or concentrating solids in a liquid feed material is described in this paper, where the feed liquid leaving the condenser section, warmed by absorption of heat of condensation, is then further heated to a temperature below the boiling point of the liquid and then transferred to an absorption section.
Patent
Water purification system
TL;DR: An integral water purification system including a tank for containing unclean water located at the source with continual replenishment of said water in the tank, a cover for the tank to accumulate natural heat by the elimination of any disturbances by the elements and to aid such accumulation by the rays of the sun in order to vaporize the water, a blower for moving the vapor to a pipe leading from an area of one temperature to another and lower temperature such as from the crest to the depth of the sea, whereby the vapor is condensed into droplets and accumulated in a condensing unit as
