Eurekalert June 8, 2018 In 2017, researchers at UC Berkeley successfully field tested their newest prototype water harvester in the Arizona desert. It worked as designed, sucking water out of the air without any power other than sunlight. They demonstrated that the harvester should be easy to scale up by simply adding more of the water absorber, a highly porous MOF. A team of researchers in the US (UC Berkeley, Lawrence Berkeley National Laboratory) has created a new MOF based on aluminum, called MOF-303, that is at least 150 times cheaper and captures twice as much water in lab tests. This […]

Microengineered slippery rough surface for water harvesting in air
Nanowerk March 30, 2018 A team of researchers in the US (Pennsylvania State University, UT Dallas) developed a pitcher plant-inspired slippery surface with hydrophilic chemistry. They added the directional grooves and gave the new surface a microscale roughness that increased the surface area. The rate of water and fog harvesting are directly proportional to the amount of surface area on which droplets can form. The rice leaves-inspired grooves whisk the water droplets away through capillary action or gravity. If the slippery rough surface (SRS) material is produced at scale, they estimate that over 120 liters of water can be collected […]
