Method of and means for obtaining a supply of fresh drinkable water. Henri Coanda, Marguerite Coanda, October 5, 1955: GB737909-A (1 worldwide citation)

Drinkable water is extracted from moist warm air by cooling it to a temperature below its dew point. The air enters a cooling unit at 3, is cooled on passing around pipes 6, and leaves the unit at 13. As the air is cooled water in the air condenses on the pipes 6, and drains into a collecting space ...

Improvements in or relating to process and apparatus for purifying water by distillation. Henri Coanda, Marguerite Coanda, October 31, 1956: GB760517-A

In a process for the purification of water by distillation, a current of air is heated while flowing through duct 2 by employing mirrors 12 and 3 to concentrate the sun's rays 16 upon the duct, the heated air is passed into heat-insulated chamber 56, the water to be purified is sprayed into the cham ...
