And a lot of other places but this 3rd gen is a LOT more efficient at it. I have seen ancient stone piles in the desert that collected water 2000 years ago or more. Just put up a pile of stones maybe in the shape of a pyramid the bigger the better and no grouting just piled stones and you will collect water but these new Metal Oxide Frameworks extract a lot more pound for pound.
