A dome may be designed with towers that intersect the dome's structure,cables extending downwards from these towers may be used to support the dome's weight. The upper portions of these towers may also be used to support windmills,as shown in the illustrations below.
Above: A tower supporting a windmill with four cables extending downwards from the midpoint of the tower. The four cables support a section of the dome,while the tower itself supports the windmill.
Above: A dome supported by four towers,with a windmill on top of each tower. The windmills may be used to produce electricity to operate industrial equipment inside the dome.
