Abstract
Atmospheric water extractor apparatus and method including a compressor an evaporator and one or more removable reservoirs for collecting drinkable water that has condensed on the evaporator. First and second chambers are provided separated by free-floating piston for alternately condensing refrigerant gas in the first chamber and storing refrigerant liquid in the second chamber, and condensing refrigerant gas in the second chamber, and storing refrigerant liquid in the first chamber. Lines inter-connecting the compressor, evaporator, condenser and the first and second chambers of the gas piston cylinder enable the compressor to alternately introduce refrigerant gas into the first chamber and move refrigerant liquid into the evaporative means by displacement of the free-floating piston and introduce refrigerant gas into the second chamber and move refrigerant liquid into the evaporator by first displacement of the free-floating piston.
