For OrthoKiteBunch there is also a simplified version with two distant and alternating winches for an unity, and in yo-yo mode. That said superimposed kites would require a perfect control, leading to high risk of collision or tangle.
It looks that Advanced Kite Networks (AKN), settled within their multiple anchors could mitigate the management issue (no undesired brush effect), and improve the real potential density. With tests one would know better about AKN.
As an option I would envisage to simplify the architecture with a single kite area protected by a network of straps holding the tethers, and with holes (in the kite area) to let the air through for stability. An approximately circular in shape multi-anchored isotropic kite in Santos way could be deformed from the winches to change its aerodynamic design according to the forth and back trajectory, according to the wind direction, for example by towing on chosen winches. An automated simplified control system would be useful.
