Water Out Of Thin Air

Engineers have been chasing methods to produce water without the need for complex and costly systems. Researchers at UT Austin have developed a low cost gel film that can extract water from air. This super hygroscopic polymer film (SHPF) is made from just two inexpensive, non-toxic biomasses: Konjac glucomannan (KGM) and hydroxypropyl cellulose (HPC). In areas with just 30% relative humidity, 1kg of material can produce 13L (3.4g) of water a day. We’ll be keeping an eye on this technology.
