Windmills, Vertical, Horizontal, and DIY InDepthInfo

Windmills: Converting Cheap, Clean Wind power to Electricity. 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. However, for large turbines variable pressures on the blades at different heights can cause severe stress on the blades and bearings.

Windmill ship Wikipedia

A windmill ship, wind energy conversion system ship or wind energy harvester ship propels itself by use of a windmill to drive a propeller.. They use wind power through a mechanical or electrical transmission to the propeller. Where transmission is electric, storage batteries may also be used to allow power generated at one time to be used for propulsion later on.
