Abstract
Potable water is produced by extraction of water vapor from air. Water absorbed inside a desiccant bed is forced into vapor phase by using input heat energy, for example, waste heat from the exhaust of an internal combustion engine. Pre-heating a portion of the desiccant material prior to desorption enhances efficiency. Energy for the pre-heating may be obtained by recovering heat from the desiccant material prior to adsorption.
