In the city of Yang, the S4000 power plant, capable of rising to a height of 4 thousand meters, was tested. The Helium platform holds generators using high wind energy. The dimensions of the building are 67 x 40 x 23 meters. During the tests, the unit flew for the first time in an urban environment, transmitting electricity to the ground via a tethered cable with a voltage of 10 to 35 kV. Developers expect to use stronger and more stable wind at higher altitude. This will allow the use of wind resources that are not accessible to traditional land turbines. Register MASHNEWS in MAX.
