This system could make an excellent gearing system for wind energy.  Low gears for light winds and adapt upwards as the wind increases maximizing the rotation of the mill.  Usually mills are single gear and either take a certain amount of wind to start (which can cause the mill to sit still for long periods) or they spin too fast and have to employ a braking system at higher speeds.
