"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 "
They’re trying to get it to100kW. That’s like a pretty big generator but not a huge one. So this isn’t a replacement for wind farms just yet. The picture is from a year ago. No mention of costs.
Would it be possible to use heat to get it to float, instead of helium? Heat it up with electricity.
The article says:
That suggests to me (admittedly a layman) that each blimp is more like 1.2MW?
The title itself already says it’s 1MW.
