• What about the higher bending modes of the weaker tower for large turbines? I suspect that you'd need cables at multiple heights to stabilize against that.



• What about cable maintenance? In comparison to radio towers, I would expect a higher strain on the cables due to all the turbine vibrations and the nacelle mass. A cable in the sea, even more so.



• What about cables and access by sevice ships?



• Cables would also increase noise and bird deaths, but I'm not sure by how much.
