China sets new airborne wind turbine record at 4,000m — this 747-sized helium blimp generates megawatt power from high-altitude winds
China’s S4000 airship channels the wind to generate electricity at 4,000 meters above the ground.
China has successfully tested an airborne blimp called the S4000, which generates electricity from wind power at an altitude of 4,000 meters. The airship, resembling the size of a Boeing 747, is capable of moving to areas where wind power is most needed. According to Chinese state broadcaster CCTV, the S4000 ascended to its designated height, generated power, and then returned to the ground.
The craft, sporting turbines on each side, captures stronger and steadier winds found high above the Earth, sending the generated electricity back to base via a long tether. Developed by Sawes Energy Technology, Tsinghua University, and the Chinese Academy of Sciences, the S4000 is an attempt to revive the age of blimps and utilize high-altitude winds more effectively.
