One of the interesting sights at the Judge Roy Bean Visitor Center is the Model P Eclipse Windmill from 1900.  These windmills were typically sold as a kit, transported to their location in pieces, and constructed by the owner.  The engineering included “a regulating mechanism to keep wheel pointed at an optimum angle based on both the wind speed and direction”.  Under light to medium wind speeds, the Windmill would work normally, but if the winds were too heavy, the Windmill was designed to align itself angled to the wind gusts so that it would not be damaged.  This one was a pretty cool piece of history.
