"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 "

Cool. A couple of decades ago I read about former astronaut/physics prof Wubbo Ockels working on something like that but with kites. I've never heard of any production version of that coming off the ground. I hope this does better.
