A German non-profit foundation, Alpha Spring, has been researching and developing a liquid desiccant type water-from-air system for several years. A prototype has operated successfully for over a year in southern Germany. The foundation is now crowd-sourcing on indiegogo to fund construction of their pilot installation in a region with water-scarcity. Visit the foundation's website and their indiegogo crowd-sourcing page (which includes a video) for more details.
I have been researching and developing drinking-water-from-air technologies since 1984. As a physical geographer, I strive to contribute an accurate, scientific point-of-view to the field.
