Water from Nothin'

Fog collection in the Atacama Desert, Chile - Nicole Saffie
The Atacama Desert is one of the driest places on Earth, which is why the ALMA radio telescope project is there. Fog collection is a one way to collect drinking water out of the atmosphere that doesn't require any energy. Getting a usable amount of water out of the air in the desert is a pretty good trick. But if this is a desert, then what are all those clouds doing there? I think they must be right on the western edge of the desert, that horizon looks like the Pacific Ocean.
