Pierre,
TUK was unaware of KiteLab’s prior work when they published, but since then we have exchanged many nice emails on shared AWES concepts. Be patient in how this research unfolds to meet your criteria for acceptability.
The tri-tether method actually helps constrain the kite to a tighter pattern scope than a single-line can, and better retains the kite inside the land footprint, with far less chance of breakaway, than single-line topology.
Our oldest variable tri-tether aviation case is a 1930’s Zeppelin patent, at a grand scale. Tigner’s patent shows tri-tether array scaling.
