Windmills
Windmills were used in Persia (present-day Iran) as early as 200 B.C.[1] The windwheel of Hero of Alexandria marks one of the first known instances of wind powering a machine in history.[2][3] However, the first known practical windmills were built in Sistan, an Eastern province of Iran, from the 7th century. These "Panemone" were vertical axle windmills, which had long vertical drive shafts with rectangular blades.[4] Made of six to twelve sails covered in reed matting or cloth material, these windmills were used to grind grain or draw up water, and were used in the gristmilling and sugarcane industries.[
