Ancient Persian Vertical Windmills Still Grinding Grain
2023-06-13
[Epoch Times] When we think of wind power as a source of energy, we might think of huge, ugly turbines blighting the landscape. But one village in Iran reveals how our ancestors built turbines using wood and clay, not steel and concrete; with such smarts, they are still being used today—some thousand years on.

Blending into the semi-desert landscape, constructed high on a hill, an army of 40 windmills stand up to 65 feet (approx. 20 meters) high and serve two purposes: to act as a buffer, protecting the village from the raging air currents, and to grind grain into flour. Locals call the technique of using wind to power milling machinery "asbad." In a stroke of genius, Iranian architects positioned and designed the windmills in such a way as to "catch" the air in openings, causing the blades to spin, which in turn powers a vertical shaft that turns a millstone, grinding the grain.
Nice photos at link.

#1  Guess these ancients didn't believe in planned obsolescence as a design strategy.
