Researchers develop solar-powered moisture harvester that collects and cleans water from air

New research from UT Austin engineers may help provide critical access to clean water in disaster situations and water crises, as well as poverty-stricken areas and developing countries. A team led by Guihua Yu in the Cockrell School of Engineering has developed solar-powered technology that relies on hydrogels – gel-polymer hybrid materials designed to be “super sponges” – that can retain large amounts of water. As described in a recent issue of the journal Advanced Materials, the sponges have been successfully tested in humid and dry weather conditions.
