Generating water from Fog |

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.

Dear Gyeongrin, its' indeed cost effective. The green techniques are sometimes cost intensive therefore are resistant. Thanks.

Hello Rohan
Water exists in various state condition and to exchange fogs in to drinking water seems to be an marvelous idea.
Also its very nice of you to actually state about the cost of this project as techniques always face the trade off problem in finance and quality.
Thanks for sharing about this unique method!

Hello Rohan, such an iconic idea brings us brand new technology-based environment-friendly living to us :)
Though it needs some specific restrictions or geological basis to develop, we can make use of nature without harming them and we know how to do so without using 'black gold' or killing other living organism.
Thanks for your report, I never saw such water-gaining net technology before :)

Hello,Rohan Kapur
Namaste from Nepal, Country of Mt Everest
I wish for your healthy body, peace mind and happy face in coming days, I wish you always can serve for this beautiful earth,
Happy New Year 2019,
In this Year
Donate Red (Blood)
Spread Green (Plants)
Save Blue (Water)
Thank You so much for your report about report about making water from fog, i saw a video about this technique, it is really awesome idea where there is scarcity of water.
Keep writing :)

Thank you Rohan for such a beautiful report.
Such technology can be of great importance in the arid region. With the increasing effect of climate change which has resulted significant change in the rainfall pattern this can be the adoptive measures in the many regions.
We are very thankful for sharing this new project with us. Keep writing great reports.
Wishing you happy and prosperous New Year

Seasons greetings Rohan!
I trust you are well!
It is very practical that the arid regions are relying on fog especially those who are closer to the coastal regions because fog condensers much quicker than that of a rain droplets which needs to accumulate to a certain mass in order to drop down as rain which does not happen often in the desert.
I commend the work of all those who participated in ensuring that the 5 villages get adequate water sent down to them. Water is life and now they added one more valuable resource source for villages in water deficient areas to receive water.
I am thankful that you have shared this beautiful message in your report please continue sharing such wonderful updates of how people are making a better living for all those who have a right to a basic need that they have no access to.
Thank you for the lovely report Rohan!
Yours sincerely
R.
