Rod, the land use management looks to be reasonable. And also your system is potentially more suitable in regard to the land use issue for many reasons such like redundancy of constrained tethers in rotating columns of low radius, small elements in flight, and above all a far better potential of Power to space use ratio.
The network will work well when winds lead it in expansion. Problems can occur when winds will lead it in contraction. For these problems I would suggest to think about the AWES farm in bumper car mode concept. Why not using some lifter kites (for example some unities of the Sharp rotor that is stiff enough) as separators?
