Abstract
Harvesting water from ambient air has been an emerging technol-ogy to address the critical challenge of water shortage at a global scale. In a recent study published in Cell Reports Physical Science, Wang and colleagues created a novel solar-driven atmospheric wa-ter harvester featuring a hydrogel-based composite sorbent (PCLG) and a rationally designed honeycomb structure, which demon-strated a superior water uptake capacity and greatly enhanced vapor transportation efficiency.
