Pumping water and generating electricity are common uses but windmills originally milled things :) The basic requirement to call something a windmill (for the purposes of UVL) should be a shape to catch the wind and translate it
directly into rotational motion. What the rotation motion is used for (pumping, travel, milling, electric generator) is not relevant.
