"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 "
Incredible progress on a concept that has been seeking investment for last 15 years. It doesn’t just provide 1.2mw, it also operates at a higher capacity factor than capturing winds closer to ground. I’m sure it can scale even higher.
This is useful for clean energy shipping. Design supports an unthethered airship that produces H2 and transports it at the same time. I believe the design would support forward momentum directly upwind, but some tacking angle would be supported.
This is not just a breakthrough in wind energy generation, it is a breakthrough in airship capability.
Meanwhile in the US, rich assholes are firmly convinced coal and oil are the future.
God I hate this place.
It’s late stage capitalism.
These fools are just hoarding what they have and trying to continue the « golden age ».
China will be the next superpower for sure
An untethered AWE cannot produce any power
Contentious. Thethering increases power production by restricting the “sail movement power”. The blimp part is highly/perfectly aerodynamic, and the betz limit means that a turbine does not fully “act like a parachute”. Ground vehicles that proved faster than wind speed directly upwind could use similar principle to turn a propulsion prop, that increases forward/apparent wind speed generating more power.
This relates to same incredulity for faster than wind upwind ground experiment, and needs experimental proof. But principles of sailing are indeed magical, and simply generating enough power to move forward is extremely useful, even if tacking were needed.
Also, it looks cool as fuck!
…produces H2?
electrolysis of water (partially from starting water reservoir, and partially from air humidity = dehumidifier step), can displace water weight with increased H2 pressure in airship. Can put an infinite amount of these over ocean with no land lease costs, but moving giant ships solves the issue of thethering them.
