🇨🇳China has launched the world's most powerful flying wind turbine, writes South China Morning Post. The S1500 turbine by Sawes Energy Technology is the size of a basketball court and as tall as a 13-story building.

Compared to other wind turbines that stand on the ground and resemble windmills, the S1500 can ascend into the sky thanks to a helium-filled envelope and transmit energy through ultra-strong cables.
