"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 "
How so, when skysails talks about “Venyo harnesses the power of high-altitude winds with speeds of 13 m/s and a continuous output of up to 200 kW.” while the S1500 is featured with “Inside this duct are 12 turbine-generator sets, each rated at 100 kW.”?
It’s more like factor 5-6.
Their v2 product produces about 5kw at much lower altitude (weaker 9m/s winds). 13m/s is a big ask. They don’t go as high as 1000m. I was comparing to their v2 product instead of the 200w theoretical max of their v1 product. But the blimp may not produce 1.2mw all the time either.
Yah, we need to have them running to get real numbers.
I find both approaches promising.
Ways to make electric energy available without burning fossil fuel are good.
