China has completed a test flight of what it says is the world’s first megawatt-class high-altitude wind power system designed for urban deployment. The enormous S2000 Stratosphere Airborne Wind Energy System (SAWES) flew at an altitude of 2,000 metres in southwest China’s Sichuan Province, generating electricity and successfully connecting to the power grid - a world first for a high-altitude wind power device.

For now, it’s still in test phase but could one day be the future of wind power in cities.
