A mesh can extract water from fog with some purification [View all]
Last edited Sat Aug 26, 2023, 06:56 AM - Edit history (1)
Researchers at ETH Zurich have now developed a method that collects water from fog and simultaneously purifies it.
This uses a close-mesh lattice of metal wire coated with a mixture of specially selected polymers and titanium dioxide. The polymers ensure that droplets of water collect efficiently on the mesh and then trickle down as quickly as possible into a container before they can be blown off by the wind. The titanium dioxide acts as a chemical catalyst, breaking down the molecules of many of the organic pollutants contained in the droplets to render them harmless.
