How would an early Persian windmill compared to an early European windmill

Persian windmill blades were vertical, like propellers,  while European ones were horizontal, like egg-beaters.

Explanation:

A windmill is a functioning engine sort of thing. This transforms energy from the wind into rotational energy. For this reason this requires vanes called sails or blades. The very first windmills featured with long vertical shafts with blades designed like rectangles who lived in ninth-century Persia.

Six to twelve sails were produced of those windmills. The sails had been coated with matting reed or fabric. They differed greatly from the European editions. In 13th century China a similar nature of vertical shaft windmill with rectangular blades was found used for irrigation. Overall around 60 AD vertical axle windmills had been found in eastern Persia. In the 1180s northwestern Europe developed horizontal axle windmills. It is the form that is often employed today.
