A Chinese energy startup has successfully completed a test flight of an innovative airborne wind power generation unit, reaching a record altitude of 2,000 metres.
Developed by Beijing-based Linyi Yunchuan Energy Technology Co., the floating turbine, known as the S2000 SAWES (Stratospheric Aerial Wind Energy System), aims to bring the concept of "flying power plants" to reality. The unit is designed to produce enough electricity in just one hour of operation to fully charge approximately 30 electric vehicles.
New unreal airborne wind turbines that float to harness high-altitude winds are being used in China.

During the 30-minute test flight, the system ascended to its target altitude and successfully generated 385 kWh of electricity.
The S2000 SAWES is a massive, helium-filled structure measuring 60 metres in length and 40 metres in both width and height. By harvesting the consistent and high-velocity winds found at high altitudes, the system generates power and transmits it back to a ground station through high-strength conductive cables.
The company envisions deploying these "floating turbines" to provide sustainable energy to both major cities and remote areas across the country.
