There is no exclusive page for them on wikipedia, but I could find how they work generally here: https://en.m.wikipedia.org/wiki/Panemone_windmill
I do wonder which way the prevailing wind is for those windmills though as they are surrounded by walls. The knee jerk reaction is that the wind comes "face on" but then surely there would not be a turning force if the wind blows on both sides of the axis equally (especially since the sails look to be fixed)
I did notice there was a small vertical slit on the back wall, which makes me wonder if the wind blows "sideways" and generates lower pressure by blowing over the slit, causing the sails to move.

They’re an integral part of the landscape, part of the culture (or used to be), and harness the local environment to produce something. Same goes for rice terraces, vineyards, etc.
And yet I see many people complain about us sticking wind turbines on top of hills.
One can only imagine how the Iranian wind wills were received a thousand years ago.
I suspect it will take a generation or two for these turbines to turn them in to an integral part of our life as well. Or utter necessity.
Gotta love that cycle.
Persians are very smart people
I agree, but doesn't this have more to do with the stability of their society, in that period?
