"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 "
With a traditional wind turbine, if the wind speeds get too high, the turbine locks the rotation and feathers the blades. For the airship however, people will have to manually take it down and later erect it again. Hopefully they get to it in time, otherwise it’s going to violently take itself down and/or fly off. Either way, that is a bunch of extra cost incurred on a regular basis.
Strikes me as an impractical solution.
