Kytoons would be suitable for lift from both buoyancy and aerodynamic lift. With an elevation angle of 60 to 80 degrees, airborne solar collectors (ASC) or ASWES would occupy much less space than AWES, whose elevation angle is lowered by harnessing winds for energy generation. As a result, and unlike AWES, ASC could be installed virtually anywhere.
The gain of solar energy in altitude compared to the ground would perhaps not be enormous (but not negligible), but it would be constant whatever the season and the hour of the day, and this thanks to the possible orientation of the balloon, and the cloudy weather or not.
In a way the more constant and powerful high altitude winds are still used, but only to obtain more lift, and thus more carrying capacity of solar cells.
