Iron Man Windmill

As it exits the wind wheel, an area of low pressure is created behind the sail. it is this difference in pressure that applies a force against the sail, causing it to rotate. this design provides a high torque at very low wind speeds. because low wind speeds are the most common, it is essential that waterpumping windmills work in low wind speeds.
