Out of thin air – Well, the air may not be as thin as we think. Researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart, Germany, are working on a way to capture drinking water from air humidity. The process involves using a hygroscopic brine which is a saline solution that absorbs water. The water is then sucked into a tank by a vacuum, where it is boiled using the energy from solar panels. The water that evaporates from the boil is does not contain salt and it is condensed into a separate tube. Researchers state that is technique can be implemented on a variety of scales-from use in homes to large corporations.
