The general plan of the M-AWES farm (which could be replaced by parasails covering the same circular areas called n) shown in Fig. 1 seems suitable although obvious.
In the page 2, it is indicated that Betz limit (16/27) is considered for each of the units. So the AWES mode cannot be reeling (yo-yo) mode, being limited to 4/27 and divided by approximately two due to the time and energy of the reel-in recovery phase, i.e., eight times less. And yet there is a clear reference to reel-in and reel-out phases (for example on page 3)…
Thus the density is divided by about eight.
The angle of elevation of 40° in Fig. 1 looks possible although optimistic.
And above all, the tether lengths are not taken into account for the calculation of the density when they should (by taking account of all wind directions), due to safety issues in secondary use (farming or fishing), not to mention the risks of kites and their tethers being dragged for tens of kilometers in the event of breakages.
In the end the AWES-farm density is a tiny fraction of what is suggested.
