Congratulations for the new company thus created @tallakt.
Below there is a link of the patent by its title. There are elements that concretize some of the ideas of the Pyramid (the description is in the title itself), then extending to the use of positive or negative thrust of the respective RATs of the aircrafts, as means among others, if I understand correctly. However the Fig.1 describes a winch (1) in the context of pumping (reel-out/in yo-yo) mode (?).
A METHOD AND APPARATUS TO COUNTERACTS SLOWDOWN IN AIRBORNE WIND ENERGY
Is it an embodiment of the same system, or another AWES? I don’t see “balloons” in the initial description of the Pyramid, nor in the patent above.
