Modern Technologies
Many atmospheric water generators operate in a manner very similar to that of a dehumidifier: air is passed over a cooled coil, causing water to condense. The rate of water production depends on the ambient temperature, humidity, the volume of air passing over the coil, and the machine's capacity to cool the coil. These systems reduce air temperature, which in turn reduces the air's capacity to carry water vapor. This is the most common technology.
An alternative available technology uses liquid, or "wet" desiccants such as lithium chloride or lithium bromide to pull water from the air via hygroscopic processes. A proposed similar technique combines the use of solid desiccants, such as silica gel and zeolite, with pressure condensation.

Famous quotes containing the word modern:
“Most of our modern portrait painters are doomed to absolute oblivion. They never paint what they see. They paint what the public sees, and the public never sees anything.”
—Oscar Wilde (1854–1900)
