Windmills, Vertical, Horizontal, and DIY

Modern windmills are more properly called "wind-turbines". These are usually Horizontal Axis Wind Turbines (HAWT). They consist of rotor blades connected to a horizontal shaft, which in turn, is hooked directly to an electrical generator. A HAWT is more efficient than turbines utilizing vertical axis designs.
