Ancient Iranians vertical axis wind mills
Ancient Iranians vertical axis wind mills
- According to the Encyclopedia Britannica, the earliest known references to windmills are to a Persian millwright in 644 CE and windmills in Seistan [Sistan], Iran, in 915 CE.
- In the early second millennium, some Eastern and Western states acquired the technology of making mills from Persia (TOT!!!).
- Unlike European windmills, the Persian design is powered by blades arrayed on a vertical axis in which the energy of wind is translated down without the need for any of the intermediary gears found on the horizontal axis windmills.
- Iran seeks UNESCO recognition for arrays of its ancient windmills that can be found in the provinces of Sistan-Baluchestan, South Khorasan, and Khorasan Razavi.
not much has changed after all those years..lol
