Engineers at Virginia Tech University have developed a new, more efficient fog harp capable of harvesting water from even a light fog.I like the fact the fog harp requires no power of any sort to operate, and produces relatively pure water clearly meeting third world drinking/ cooking standards. I bet it works somewhat wherever there is dew, where the ambient temperature falls below the dew point.
The fog harp looks like a harp, with parallel wires that collect the fog's ambient water droplets. Similar devices use screen mesh, but analysis by engineers at Virginia Tech showed parallel wires more efficiently collected water and encourage drainage into the collector.
Star Wars fans remember Luke Skywalker's aunt and uncle ran a windstill operation on arid Tatooine, likely a not-entirely-dissimilar technology. Dune fans recollect the Fremen did the same on dry Arrakis and stored the water they captured in underground reservoirs.
