智利年轻人用捕雾网从浓雾中获取水资源
In the arid hills of northern Chile, where rain falls only a few times a year, a different kind of water source is being harvested: fog. Young residents have begun installing large mesh nets called fog catchers, which capture tiny droplets from the coastal mist and turn them into usable water.
The principle is simple. When fog passes through the vertical mesh, the droplets cling to the fibers and eventually trickle down into a collection pipe. A single well-placed net can produce up to 200 liters per day—enough to sustain a small family or water a vegetable garden.
