yes. Although the smart rotor concept is still in research and/or feasibility study stage.
Here is a windpark with 104 mtr diameter rotors. Notice the scale of the tugboats !
These pictures will give an even better feel of scale, notice the two persons standing on the stabilized walkway and the dinghy at the very foot of the tower. The stabilized platform uses a setup also found in flight simulators. It's base is made up from 6 very large hydraulic actuators that are computer controlled to keep the walkway level with the doorway in the tower when there are rougher seas.
Phill, these are actually the turbines that you have seen off the coast of Zandvoort. It is the windpark off "Egmond aan Zee".
