I sketched a TRPT Daisy-like with tied wings on Medium scales for torque transfer systems onshore and offshore - #107 by PierreB.
The problem I see concerns the size of the required rigid tilted ground ring for the generator transmission when the rotor becomes huge.
And also the achievable altitude is dependent to the diameter of the rotor due to the torque transfer requirement.
For a 1 km diameter rotor (it is quite huge but AWES will be competitive when high dimensions (= more or less tether length) will be reachable) such a rigid ground ring would be 0.2 or 0.3 km diameter and 0.1-0.2 km height. It was the reason why I conceived Rotating Reel System.
