Another option from the modified drawing: the photovoltaic balloon becomes a kytoon in order to benefit from high winds, and above all solar energy is used only to produce hydrogen to inflate said kytoon, not to convey electricity through an electric cable.
On the one hand, it takes a lot of energy to produce hydrogen, and solar energy just allows provide it, on the other hand, it is necessary to isolate the kytoon as much as possible in the top of the installation, in order to avoid the propagation of a possible fire through the cable.
Other lifting kites and wind turbines are installed below as shown on the modified drawing. If a rope drive device like on Kiwee replaces wind turbines an electrical cable is not required. Other (crosswind or not) AWES such like fly-gen (with the requirement of the electrical cable), even perhaps some yo-yo systems (without electrical cable) could also replace wind turbines.
