Frank Herbert stunned us with his fictional world of Dune and its sandworms, deserts, and complicated political intrigue. One of the coolest bits of tech in the Dune universe were the giant “windtraps” that collected moisture from the air and allowed the Fremen to persist in the desert despite the pesky sandworms and their annoying habit of locking up all the land’s moisture.
Well now we have windtraps on Earth! Check out this video from Lima, Peru that describes a billboard windtrap that creates water for hundreds of families in the area.
