A mesh can extract water from fog with some purification

Last edited Sat Aug 26, 2023, 05:56 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.

As long as there are no fog crawlers, I’m good with this 😁

Sounds like some great technology here. Will be interesting to see where this goes.

"Fog drip" condensing off foliage, typically measured in inches of precipitation during the drier summer months. The SF fog-infused vodka drink sounds cool. Is there a name for it? I would go with "Tony Bennett"!

for their gardens for a long time. Water condenses on the netting and drips into a tray at the bottom, channels taking it downhill to water staple crops.



This tech has spread to Peru's coastal regions on the edge of the Atacama, on the west coast of Africa in Morocco, and can possibly be used anywhere the air contains enough humidity, especially the west coast of the Americas. Here is the new tech:



Notice it doesn't even have to be fog, air with high relative humidity works. It might work on mountain tops here in arid NM, clouds pouring over the tops of the mountains before hitting the dry air here and evaporating. I have to wonder if plastic strands would work as well as metal wire, it would cut the cost for people who desperately need this system.
