Generating water from Fogby Rohan Kapur | 30-12-2018 00:02 |

Fog is made of tiny suspended water droplets. When these droplets hit the ground, they are intercepted by the trees¡¯ leaves and drip down to make the surrounding areas wet. That¡¯s crucial in the coastal ecosystem, since fog can contribute water when other sources such as rain are scarce. What¡¯s nice about fog is it tends to happen when we don¡¯t have rain. In order to convert fog into water fog nets are being used in many arid nations like Peru, Morocco etc. where rainfall is scanty but humidity is abundant.
Fog Catching nets are giant nets to catch moisture from the air, turning fog into drinking water. The technique involves a fine mesh on which tiny fog droplets typically 1 to 40 millionths of a meter, gather and merge until they have enough weight to travel down into a reservoir. Set in a dry, mountainous area, it's the world's largest functioning fog collection project, spanning 600 square meters. The pilot project now provides clean drinking water to 500 people in five villages, in a region that has been severely hit by climate change-induced droughts. This lies on the edge of the Sahara, in southwest Morocco, giant nets catch moisture from the air, turning fog into drinking water.
The nets, which are set at an altitude of 1,225 meters (4,000 feet), collect an average of 6,000 liters of water a day, which is first filtered for impurities before traveling through eight kilometers of piping to reach homes in the villages. The fog is pushed by the winds from the ocean and is trapped by the mountains it's stuck here so it's easy to empty it of its water. The mountains are draped in fog for about 140 days a year. In recognition of its unique contribution to facing the challenges of climate change, the project was awarded the 2016 United Nations Momentum for Change award and showcased at the UN's climate change conference, COP22, in Marrakech, Morocco.
These nets are very cost effective. The cost of building a fog net is about USD 500 and can yield up to a small cylinder of 100 liters of water per day, a saving of almost 60% in water usage.
Fellow Ambassadors, when I learned about this unique project through a WhatsApp forward, I thought that it will be worthwhile to share this with you as it contributes to green living and is beneficial towards the eco-system. Taking from the nature the bare minimum for survival.
One Video is also shared in order to have more information. Thanks for reading.
