Abstract: A method by which water may be extracted from the air even without a supply of electricity from a power source or even without a supply of fuel, as well as an apparatus therefor, is disclosed. The apparatus used for the method for extracting water from the air comprises at least a rotatably mounted hygroscopic moisture-absorbing rotor having at least one region through which air can pass in the direction of thickness thereof; a passage for regeneration through which air for regeneration is circulated, of which both ends are opened at the opposing two surfaces of a regeneration region, respectively, the regeneration region being a part of the moisture-absorbing rotor, at which the moisture-absorbing rotor that absorbed moisture is regenerated; and a drain hole for taking out condensed water from the passage for regeneration.
