Solar Energy Triggered Clean Water Harvesting from Humid Air Existing above Sea Surface Enabled by a Hydrogel with Ultrahigh Hygroscopicity
A/Prof Tan Swee Ching and his team have successfully developed a novel solar energy triggered, low-energy method to pull clean water from humid air that exists above sea surface. A super-hygroscopic hydrogel, capable of absorbing more than 4X its own weight with water was employed for the process. The team had constructed a floating prototype
