Good heavens, I never heard of such a thing before. Using channeled wind to pump water from underground aquifers in the desert, a couple of centuries BC in a culture that didn't even have writing.
A culture that couldn't have even *been* a culture unless they first installed the technology. Think of that.
Holy cow.
