World’s first megawatt-level airborne 'windmill' feeds power to grid

The world's first megawatt-level airborne wind power system, developed by Beijing Linyi Yunchuan Energy Technology, successfully completed a test flight in Yibin, Sichuan Province, China. The S2000 system, also known as SAWES, ascended to an altitude of 6,560 feet and generated 385 kWh of electricity, feeding it into the local grid. The system uses a helium-filled aerostat and 12 turbines in a ducted design to harness high-altitude winds for power generation.
