Not really sure how those ideas are all that similar to the TURN here. Those are long flying and involve tethering, but the flight systems are quite different and they're tethered to the ground.

Similar ideas have been suggested using balloons:

An array of wind-powered drones could scale well beyond what's possible with a traditional wind turbine, since most of the torque gets applied at the wingtips. There might be advantages with inconsistent wind gusts too, since the rotor could wind up in strong wind and unwind in weak wind. Startup costs would be negligible since a few drones could start the rotor and more could be added as needed. It might even by safer for birds if a drone array turns slower than a fixed rotor.
