A wind turbine includes a nacelle that houses a dynamo and a vane wheel coupled to an end of the dynamo. The second switching device communicates with the first switching device and operates in association with an operation of the first switching device. In one embodiment, the method of fabrication the Ge-FinFET element includes forming silicon fins on a substrate and selectively growing an epitaxial layer including germanium on the silicon fins. This is preferably done in a TekFlow\xae processor.
