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 "

    I’m out of practice with my physics so apologies if this is a n00b question, but:

    I’m unclear what (rho V) is and how you converted to that from mass (m). Further unclear what (rho A d) refers to.

    Can you explain / link to an explainer on this?
