How Do You Capture Water From the Air?

Fog water occurs when cold air passes over relatively warm water. The air is cooled and moistened, causing the dew point to increase, causing condensation of water vapor leading to the formation of fog. Usually when we say “FOG” people relate it to the lowest lying clouds in the winters or may be the condensed form of water vapours lying low to the surface of the earth, due to which there’s a visibility problem. In the Atacama Desert of Chile, fresh water is extracted from fog and used to irrigate crops of Aloe vera in Chañaral province. In nature, you can see that plants with narrow leaves are more efficient in capturing the small water droplets. Can you actually collect water droplets from fog?
Adding a nanofiber mesh makes a fog trap more efficient at catching the tiny droplets that could otherwise pass through wide gaps between fibers. Electro spun fibers are already used in air filters and dust-cleaning cloths and can be mass-produced at low cost.
This simple technology could help provide clean drinking water in many parts of the world that lack infrastructure and which increasingly suffer water stress, even ones as dry as the Atacama deserts. Let's begin to harvest fresh water from an abundant source that surrounded mountains for most of the year: FOG.
