This is something that came up while Sepp was in Bozeman. And then I
noticed we didn't have a thread about it at permies. So today Cassie
set us up with one.
The low tech version is simple. When you have a stack or rocks, the
rocks in the middle are cool. When warm summer air passes through the
rocks, water condenses on the inner rocks. Thus sorta watering that spot.
Air wells are taking that same idea and scaling them up. I think there
is a lot of research still to be done in this space.
