China tests world’s largest megawatt-level flying 'windmill' airship
interestingengineering.com
China’s S1500 airborne wind turbine completes maiden flight, becoming the world’s largest floating wind-power generator.

"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 "

      Hmm interesting. I don’t see how it could be economical as an emergency-only power source. To build them and store them for occasional use seems pretty unappealing. Surely if you had them, you’d use them to generate electricity/passive income.

      You could think of them as easily mobile power systems, available to respond to emergencies, but used wherever is convenient the rest of the time.

      So yeah, they’ll still be a hazard for air traffic, but luckily we do have an established solution for that, the blinking red light. Also, controlled airspace around airfields.
