Patent ID: 7306654

Claim:
A method of recovering water from air comprising: (a) providing an absorption system for effecting removal of water from atmospheric air flow by an hygroscopic liquid mixture comprising: an absorber vessel defining a space for facilitating contact between air having water vapour and an hygroscopic liquid mixture, including an input air flow inlet, configured for introducing an input air flow having water vapour into the space, a depleted air flow outlet, configured for discharging a depleted air flow, and means for introducing a hygroscopic liquid mixture into the space for effecting contact between the hygroscopic liquid mixture and the input air flow; and a base; wherein the absorber vessel is rotatably mounted to the base about an axis for effecting positioning of the input air flow inlet at a desired position relative to the axis; (b) measuring the direction of atmospheric air flow; and (c) rotating the absorber vessel about the axis so as to effect desired positioning of the input air flow inlet relative to the atmospheric air flow direction in response to the measured atmospheric air flow direction.
