Systems and methods are disclosed for extracting freshwater from 
atmospheric humidity in extremely 
hot and humid climates and supplying freshwater to a small group of people, a building, a farm, or forestation area. The freshwater is treated to provide drinking water by disinfecting to eliminate microorganisms and 
filtration to remove suspended 
particulates from air, 
erosion or 
corrosion products, and disinfected waste. Compact units provide drinking water for individuals, passengers in cars, vans, trucks, or recreational boats, or crewmembers on a seagoing cargo ship whether from 
atmospheric humidity or from 
moisture-laden gases. Furthermore, systems are disclosed for the ample supply of freshwater with minimal treatment for small- to large-sized buildings in a manner that alleviates the 
heat load on buildings. Collection of freshwater from hot humid 
ambient air is also provided for other uses, such as 
irrigation and farm animal drinking. Various methods are used for condensation of 
water vapor suspended in the air as alternative to conventional 
refrigeration cycles using CFC refrigerants. Devices are disclosed using naturally occurring brackish cold water, circulation of cooling 
water cooled by 
thermoelectric cooling or thermoacoustic 
refrigeration as well as evaporative cooling and 
transpiration cooling. Water produced by the systems may flow under gravitational forces entirely or with the assistance of boasting pumps.
