Overview
- The S2000 Stratosphere Airborne Wind Energy System was flown above Yibin in Sichuan Province, with output figures reported by its manufacturer.
- The prototype generates electricity aloft and sends it to the ground through a tethered cable, according to the company’s CTO, Weng Hanke.
- Developers list a 3‑megawatt rating and approximate dimensions of 60 by 40 by 40 meters, as relayed by state‑affiliated media.
- Reporters note unresolved issues for commercialization, including tether reliability, maintenance logistics, grid stability, and airspace safety.
- Potential applications cited by the company include off‑grid supply and complementing ground‑based wind, with earlier trial flights reported last September.
