Very interesting news article I came across - A new high tech jacket developed by engineers at the University of Texas can pull drinking water from thin air. With the advance in fabric technology, the jacket can collect up to one-and-a-half pints of drinkable water a day, say scientists. They suggest the ground-breaking technology could benefit anyone who spends a lot of time in areas without easy access to drinking water, like hikers, campers, runners, agricultural workers, and soldiers. โWater harvesting from air is usually imagined as a stationary device such as a box, a panel. We wanted to rethink the form,โ said research co-leader Professor Guihua Yu. By focusing on the fibers rather than building another bulky device, the researchers overcame a common problem in the field. He explained that the textile incorporated into the jacket collects moisture and funnels it to detachable harvesting units, which are then โplaced in a foldable collector and heated to produce the waterโ. The jacket produced between 400 and 900 milliliters (0.7 to 1.5 pints) of drinkable water per day, depending on humidity levels, according to a study published in the journal Science Advances. Compared with conventional water-harvesting materials, the textile showed a three- to 10-fold improvement at scale. โThe important advance here is that the team did not simply make another material that absorbs water,โ said study co-author Professor Keith Johnston. โThey designed a pathway for water to move quickly, from vapor in the air to liquid on the fiber surface, and then into the interior of the textile. The researchers are now eyeing applications beyond clothing โ including backpacks, tents, emergency shelters and other outdoor gear, allowing items people carry every day to help collect water. They also plan to look at applying the technology to remote field operations, disaster response, and water access in arid or infrastructure-limited regions.
