The present invention provides a method and apparatus for extracting liquid water from moist air using minimal energy input. The method comprises compressing moist air under conditions that foster the condensation of liquid water. The air can be decompressed under conditions that do not foster the vaporization of the condensate. The decompressed, dried air can be exchanged for a fresh charge of moist air and the process repeated. The liquid condensate can be removed for use. The apparatus can comprise a compression chamber having a variable internal volume. An intake port allows moist air into the compression chamber. An exhaust port allows dried air out of the compression chamber. A condensation device fosters condensation at the desired conditions. A condensate removal port allows liquid water to be removed.

1. An apparatus for extraction of water from moist air, comprising:a) a body defining a first internal cavity internal to the body oriented along a first axis, a second internal cavity internal to the body oriented along a second axis, a third internal cavity internal to the body oriented along a third axis, and a fourth internal cavity internal to the body oriented along a fourth axis; b) a first piston adapted to sealingly engage the first cavity during motion along the first axis, disposed within the first cavity so as to form a first chamber; c) a second piston adapted to sealingly engage the second cavity during motion along the second axis, disposed within the second cavity so as to form a second chamber; d) a third piston adapted to sealingly engage the third cavity during motion along the third axis, disposed within the third cavity so as to form a third chamber; e) a fourth piston adapted to sealingly engage the fourth cavity during motion along the fourth axis, disposed within the fourth cavity so as to form a fourth chamber; f) a connection between the first, second, third, and fourth pistons adapted to transmit force therebetween; g) a plurality of air intake ports in fluid communication with a source of moist air, mounted with the body so that each chamber is in fluid communication with an air intake port; h) a plurality of air exhaust ports, mounted with the body so that each chamber is in fluid communication with an air exhaust port; and i) a plurality of condensate removal ports, mounted with the body so that each chamber is in fluid communication with a condensate removal port.
