Drinking water from fog
A beautifully low-tech solution to freshwater access in areas with negligible rainfall, fog-collection arrays have been successfully installed in Chile, Nepal, southern Africa, and other dry, mountainous regions worldwide.
“Fog collectors are inexpensive, passive devices that each produce 200 to 600 liters of fresh water a day by collecting the tiny wind-blown water droplets present in fog. Arrays of collectors produce an average of 5,000 to 15,000 liters of water per day.”
