The absorption of atmospheric water for its Transformation into drinking water Or in irrigation water, among other possible uses, it is feasible thanks to its condensation, after capturing it through different mills. In this post we will review three interesting success projects, which manage to extract water from nothing.
Said with more property, regardless of Pretty expressions But not quite exact, the truth is that getting water out of nowhere is not exactly what they do, as is obvious. The water harvest is made from the fog that is formed, whose water particles collect different inventions.
In fact, for several years the capture of fog for its conversion in water is demonstrating to succeed in the arid regions around the world. These are just an example of the very different projects That we can find, either to water crops or to supply drinking water to people who do not have easy access to it.
In this way, not only the local economy is encouraged, including the subsistence economy, but also the quality of life of Marginal populations. Let’s not forget that millions of people in the world must walk several hours a day to get water with which to meet their basic needs.
The MIT project in Chile
The Acatama desert, in Chile, is one of the driest places in the world, and precisely for that reason there is a great need for water. Although rain is an event because of its exceptionality, the clouds are loaded with moisture.
Their very small drops of water have not just had enough weight to become rain, but they are a potential source of water that manages to capture this project, carried out thanks to the Implementation of trapanieblas.
An initiative of researchers at the MIT Engineering Faculty, in collaboration with the Pontifical University of Chile in Santiago, has made a system based on suspended meshes located in the hills where there is the enough fog to supply to local water communities for irrigation and domestic uses.
His proposal achieves a greater productivity than previous initiativescoming to quintuplicate it, say its creators. This is possible thanks to changes made in the mesh spacing, in its size and type of fiber used.
Local Morocco Project
This project, implemented in Morocco, uses networks to capture the Environmental humidity. Taking advantage of the dense fog that arrives pushed by coastal winds, sufficient water is achieved to supply several villages.
In total, drinking water is provided to about 400 people, and a Expansion recently implemented has increased productivity significantly. Since it is a scalable system, its success means not only to obtain water but be able to do it every time in greater quantity.
It is located in the Sahara desert, and consists of large networks that capture the drops of water that are suspended in the air to relieve the drought that the area suffers, known as Aït Baâmrane.
With this name a Mountain region that politically is a Confederation of Berbres de Morocco tribes, although the project is located exactly in the mountains close to it to take advantage of its advantageous conditions.
As in many other regions that lack water, air currents can bring water in the form of condensed moisture that adopts fog form, a circumstance that can be used, as this system does, an initiative of the NGO to give if HMAD.
Since its inception, in 2005, the system achieves an important average performance, from 6,300 liters per day, increasing as it expands. Of course, ocean winds only bring enough fog to produce water for six months a year.
The system is very simple. When the fog It reaches the networks at an altitude of 1,225 meters above sea level, condenses and is then the ideal time to capture drops on the networks.
The following grass is to make them collect them through pipes to finally clean it by filters fueled by Photovoltaic panelsbeing ready for distribution directly to households through a network of pipes.
The ‘Twins’ of the Desert
The third of the projects is the work of the creative AP Verheggen and his team, who after years of study finally launched their idea in a practical way. They did it in the Sahara desert, one of the most Dry planet.
The result of his experiments were positive. On the one hand, they had a Great ally that is not lacking in these parts, such as the force of the sun, and on the other some devices (The “twins”) built to extract water through condensation.
They performed tests in the Sahara desert that extends by Mali, where environmental humidity is rather scarce. Even so, they managed to produce water, despite not being working in ideal conditions, that is, those for which it was designed.
In particular, it was designed for use in the Netherlands, where environmental humidity is much greater, but it was still possible to produce water. Improving productivity, for now poor, is the intention of Project teambaptized as Sunglacier. Therefore, we will have to wait for a while to know which future of this invention. For now, it has very positive aspects, such as operating with the energy of the sun and extracting water in especially complicated circumstances.
