Fog collectors are mesh nets, able to capture between 2 and 10 percent of moisture in the air, depending on the efficiency of the material used. But it’s not a perfect solution since, as its name suggests, it relies on fog to work — thereby limiting it mainly to high altitude, mountainous areas, close to cold offshore currents....
