Harvesting Fog for Water ter Chile and Peru, Owlcation

I love to travel and explore fresh places. I hope my articles encourage you to visit them too.

Fog and Waas Nets

When I very first read about the concept of fog nets, I thought this vereiste be a kleuter of magic. Poor communities can get drinking water by harvesting waas and fog. They place a fine netwerken te the cloud layer that cloaks their mountain tops or they can waterput one te the nevel that rolls onto arid coastal areas. Amazingly, the little droplets that are caught coalesce te their millions and trillions to become a vital source of water.

Ancient very first nation and aboriginal civilizations have always known about this cloud harvest, but until recently, the technology has bot forgotten by the developed world. Rapid population growth and commercialization of water supplies has made it difficult for some communities to get enough water. Researchers have bot investigating ways to make their living conditions more sustainable. This fresh version of an old idea is already helping to improve the lives of many marginalized groups and will no doubt be adopted more widely ter the future.

How Do Fog and Waas Nets Work?

Cold air holds less moisture than warmer air does. There is a natural fluctuation te air temperature which results te water condensing out of the air mass spil dew. This variation ter humidity may be caused by diurnal rhythm i.e. day switching to night. It can also occur due to switches te elevation. Spil warm air is lifted by thermal currents it cools and so releases its water explosion.

A fine-mesh chunk of netting is strung inbetween poles so that it drapes spil a vertical sheet. The fog or waas netwerk captures the dew drops spil they are released from the cloud. The volume of drops collected means that the water forms rivulets and runs down into a gutter placed at the bottom of the nets. From here the water is channeled into storage containers where it can be accessed by the local community. The water collected te this way is used spil drinking water spil well spil to irrigate crops and for washing and cooking.

Coastal Fog ter Chile

The Atacama Desert te Chile is one of the driest places ter the world. Ter fact, some parts of it have never, everzwijn, had any rainfall at all. However, the area does get a lotsbestemming of coastal fog. Ter latest years, researchers from MIT University, USA and the Pontifical University of Chile ter Santiago have developed the meshes used to collect water droplets from the fog.

The scientists looked to nature for inspiration. They noticed that plants with narrow leaves are more efficient at catching petite drops of condensate and incorporated this into their fabric vormgeving. By switching the mesh size and the surface materials used they have improved the mesh screen’s fog collecting efficiency by 500%. The movie below shows how a fog nets are being used to provide water te the Atacama Desert region of Chile.

Elementary Technology Can Provide Sustainable Water Source

A communal system of suspended mesh nets harvests enough water for local agricultural and domestic use. However, the fog collecting nets are still at the experimental stage. Their success will only be assured if the local population is persuaded that the idea is sustainable.

There are about Ten billion cubic meters of water available annually ter Chilean coastal fog clouds. If just 4% of this is harvested, it would provide enough drinking water for the local population. Harvesting fog water spil a source of fresh water is a better option than sea water desalination. It is a low-tech option and is much cheaper than desalination methods. Fog nets are inexpensive to produce and they have almost zero maintenance costs. Once poor communities understand the benefits of this novel water collecting system then it has excellent potential to be adopted te many areas of the world.

Cloud Catchers te Lima, Peru

Lima, Peru is a thriving capital city that receives less than 1 meetlint of rainfall vanaf year. Large sections of the city’s population don’t have access to clean drinking water. Harvesting water from the sky can literally make the difference inbetween life and death. A cheap and regular water supply means that people can grow their own food and get through te this arid area.

Te the movie below a villager describes how before they had waas nets to collect water they had to rely on a tanker that came to the village three times a week. The water wasgoed expensive and all their crops had to be watered by forearm. All this switched a year ago when the villagers installed 30 waas nets. Thesis elementary structures are collecting 200 to 400 liters of water vanaf day every day for the community. They can now use hosepipes to irrigate their crops and they have potable water for cooking, drinking and washing available all week. Cheap, clean water has switched their lives for the better.

Water is Essential for Life

It may be a cliché, but it’s true. Wij truly do need water to sustain. Humans are adaptable creatures and very few climates are uninhabitable once man (and woman) gets his thinking-cap on. Communities can use resources te various ways. Early communities tended to share essential resources like water, spil it wasgoed ter their common rente for everyone to be able to sustain. Spil societies grow richer, some people become more inward looking and materialistic. They are less worried about the overall wellbeing of their community and care only for their instant family members. That’s when vital goods like water become a private tradable commodity rather than a utility available for the public benefit.

Ter countries with regular rainfall, poor people can collect water spil the rain falls, but te dry areas of the world they have no option but to pay. Fog and waas nets seem to offerande a workable solution to the problem. However, the people who might benefit from this fresh method of water collection still need to be community minded enough to pool their resources to pay for the initial installation of the nets.
