Windmill
The first practical windmills were panemone windmills, using sails that rotated in a horizontal plane, around a vertical of six to 12 sails covered in reed matting or cloth material, these windmills were used to grind grain or draw up water. These windmills are recorded by Persian geographer Estakhri in the 9th century as being operated in Khorasan (Eastern and Western Afghanistan).
