Waterlines (Water-from-Air)
Publication
Wahlgren, R. V. 1993. Atmospheric water vapour processing, Waterlines, Vol. 12 No. 2, 20-22.
Abstract
Even the driest air around us contains water vapour, which can be extracted and used. Designs already exist for devices that process atmospheric water vapour into liquid potable water, and this area deserves to be explored.
* * * * * * * * * *
This article was the first to suggest the terminology atmospheric water vapour processing:
"…two different ways of designing an atmospheric water harvester or processor. The choice is either to harvest the water droplets, or to process the water vapour. (Harvesting is gathering the water droplets, because no phase change of the water occurs. Processing seems an appropriate word for machines which cause water to change phase from vapour to liquid.)"
