Self-lifting
You have to balance the "efficiency" in terms of power generation as well as the lifting efficiency that keeps the whole thing up.
The virtue of these spinning winged-sausages is that they have inherent lift like a box kite, so they can stay up AND carry the weight of a fairly massive turbine. (But there are some tricky torque issues that really need contra-rotating segments to work against each other, rather a single segment torquing the lifting wires)
