Chilean researchers create drinking water from fog
The Chile is one of the countries more "dry" in the world, a place where the water is, truly, a very luxurious and where researchers devote much of their time looking for innovative ways to ensure this feature.But the news that we bring goes beyond innovation, sounds like science fiction: Chilean investigators, in partnership with MIT scientists have developed a new and efficient way to create drinking water from the fog.According to explains the Wired, the system stores the fog â€" which is not new, advances the magazine-, through a kind of vertical mesh, as a large network of tennis. The technique draws on some plants and insects that survive in drier regions of the world, to take water from the air in this way.How advanced Wired, store fog is not something new and it's developed in 17 countries. The surprise of this technique goes through its efficiency, since the task force was able to optimize these networks to tune the size of the filaments of the networks, the size of the holes between the filaments and the protective coating applied to the filaments. The result is a system five times more efficient than those used so far.Apparently, the systems used until now have very large holes, which allows the fog away â€" what will not happen so often with the new Chilean system.The discovery has been published in the journal Langmuir. "Nature has made the job harder â€" evaporate water, dessalinizá it and condense the drops. We only have to collect, "explained Gareth McKinley, a mechanical engineer who participated in the investigation.Photo: under Creative Commons license
