Pure Drinking Water from Air

A couple of years ago we reported on a water from air unit we used in the Caribbean island of St. Maarten (http://www.green-trust.org/wordpress/2008/06/13/air-water-generators/). This was a compressor based unit, that works like a dehumidifier and extracts the humidity and purifies it for drinking. We recently came across a non compressor unit, which reduces cost, and energy consumption. We have a sample coming next month, and the technology looks exciting. It uses a hygroscopic film, with electrostatic and carbon filters. We will keep you posted.
