Harvesting fresh water from fog is now 500% more efficient.
Fog harvesting has become extremely popular in several countries around the world, including Yemen, Morocco and Chile. The process involves the construction of a mesh net on an elevated piece of land which is embedded by fog.
The water in the fog catches on the mesh of the net, condenses into pure, liquid water and drips down into a waiting collector. Because of recent advancements in the netting material, one 4 meter by 10 meter net can harvest 66 gallons of water a day.
According to the design paper at MIT, "fog represents a large untapped source of potable water" and by mimicking natural water condensers we can tap into it. The recent breakthrough advances the netting by creating a different shaped surface that has better "wettability."
