The world's first megawatt-class high-altitude wind power system for urban use, the S2000 SAWES, has successfully completed a test flight in Yibin, Southwest China’s Sichuan Province on January 5. After a 30-minute ascent to 2,000 meters, it generated 385 kilowatt-hours of electricity and completed grid-connected power generation. One hour of operation can generate enough electricity to fully charge approximately 30 top-spec electric vehicles from zero, said Dun Tianrui, CEO of the company. (Vid
