The Chinese Aerostat S4000 (saw) is a generator that uses wind at an altitude of up to 4000 meters. At 67 meters long, it rises without ground towers or complex infrastructure. It is held in place by a cable, and its generators produce up to 3 MW. It is designed to work in hard-to-reach and remote areas, high areas, islands and deserts. And also in emergency response areas when conventional power grids fail. The video shows the tests that the device successfully passed in the summer and fall of 2026.
