"High-altitude winds between 1,640 and 3,281 feet (500 and 10,000 meters) above the ground are stronger and steadier than surface winds. These winds are abundant, widely available, and carbon-free.

"The physics of wind power makes this resource extremely valuable. “When wind speed doubles, the energy it carries increases eightfold, triple the speed, and you have 27 times the energy,” explained Gong Zeqi "

500 to 1,000 meters AGL is going to be a problem for aircrafts. You need remote areas to have no interference bc these are big balloons.

That is not how it works. Air ways would be rerouted and emergency aircraft would be effected. The cords would be the hidden danger.
