"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 "

High-altitude winds between 1,640 and 3,281 feet (500 and 10,000 meters) above the ground

So y'all will have in depth conversations about the meaning of the colors of a fucking Labubu with ChatGPT, but can't be bothered to ask it to do the math on this?

Cause 10,000 meters isn't 3,281 feet.
