Scientific American reports on new technology to catch rainwater in Peru. The article states that:
"When dense fog sweeps in from the Pacific Ocean, special nets on a hillside near Lima, Peru, catch the moisture and provide precious water to an area that gets very little rainfall--about half an inch (1.5 centimeters) a year.
The nets stand perpendicular to the prevailing wind, which blows fog into the coarse, woven plastic mesh. From there, drops of fog-water fall into gutters that carry the water to collection tanks".
