The blades are connected to a drive shaft so that when the wind causes the blades to turn, they then rotate the drive shaft. The holes generate turbulence, which acts as a brake (and also reduces lift). [29], The evidence at present is that the earliest type of European windmill was the post mill, so named because of the large upright post on which the mill's main structure (the "body" or "buck") is balanced.
