Tether(s) as element(s) of structure

The tether is the far longest element of almost all intended AWES, being able to reach 1 km. So why not use it as a very light and structural element thanks to its tension, to support some other elements?

Some architectures use (a) tether(s) as (an) element(s) of structure, such like some tethered SuperTurbine ™ (video 1), TRPT Daisy stacked rotors (video 2), FlygenKite (video 3), Pacific Sky Power (similar to FlygenKite) (video 4) and so on.

This topic is intended to imagine some other possibilities.
