The Nashtifan windmills have a vertical axis, an arrangement in which the millstones are attached to the windmill's vertical driveshaft. Nashtifan's 120 mile-per-hour winds spin the blades, which spin the shaft, which spins the millstones, which grinds the grain. The downside to this style of vertical axis windmill (called a panemone) is ...Web

Horizontal and vertical turbines also differ in blade design. While both horizontal and Darrieus-type vertical turbines generate lift, the difference in their axis of rotation means the blades function differently. The rotor plane of a horizontal turbine is at an 180 degree angle to the wind flow, so the speed and angle of the wind vary along ...Web
