Not such a novel idea (Score 1)

So a few years ago I met this old retired engineer who explained what he'd been doing in his working life. The one thing he was most proud of was being part of a project where (waaait for it...) turbines that condensed water from the air were installed somewhere in Asia (can't remember exactly where) where drinkable water was hard to come by. Although I applaud this effort, it seems that the concept is hardly novel and similar machines have been used before.
