Rope-drive transmission

I think that on the current topic the rope drive transmission designs mainly a transfer of type @Kitewinder’ and variants. However other configurations of rope drives are evoked on Another laddermill concept and on What is possible with Payne's patent US3987987 figure 5? - #85 by Windy_Skies . I quote again the sketch below, that describes a ground-based rope drive pulled by at least one kite flying quite crosswind:

. This rope drive could work like NTS’ straight rail (video below) while being simpler and more transformable.

On the video above the kite flies by figure-eight while the cart moves slowly with high torque, probably tailwind. If the kite flies quite crosswind and on a side and pulls directly the cart, said cart could go faster with a lesser torque, and the kite could fly forth and back. The same could be applied for a ground-based rope drive in crosswind position. So the kite move could be like a kite surf (video below), with a tack at each end of the trajectory:
