Indeed, both Guangdong parachute device and the presented parasail device are tether-aligned AWES. They are not crosswind kites. So the power-to-area ratio is far lower than that of power kites as I mentioned. In the other hand the implementation can perhaps be easier (relatively simple control). Power to space use ratio can be comparable or higher since the whole wind area could be harnessed (while in crosswind mode some wind areas are not harnessed within the figure). And also:
And as the parasail absorbs less power per unit of area, wear could be less.
In my initial comment, I presented solutions with parachutes, showing the problems, then going to parasails as a possible solution.
The other alternative would be the implementation of power kites in Low radius loop mode. But I don’t have any ideas for yo-yo mode, other than the implementation of a control pod (close to the kite) which could be too heavy and hinder the rotations. And stacking in a train could be more difficult.
