  "account": "Beijing-based start-up Sawes Energy Technology has successfully propelled its S4000 airborne wind energy system to 4,000 metres above sea level, marking a world-first achievement in high-altitude wind power generation. The prototype, resembling an airship, ascended, maintained its position, generated electricity, and returned to ground, completing a full work cycle as reported by state broadcaster CCTV. This breakthrough could potentially revolutionize electricity provision in remote locations like deserts, highlands, islands, and disaster zones. The S4000, which is as long as a Boeing 747 and filled with helium, can tap into stronger and steadier winds prevalent at higher altitudes, thereby generating electricity. The electricity is transmitted back to the ground via a tether. Sawes Energy Technology collaborated with Tsinghua University and the Chinese Academy of Sciences' Aerospace Information Research Institute for the project. The company, established in 2023, previously developed the S1500 and S2000 models, achieving 1 megawatt and 2,000 metres power outputs respectively. The S4000 model is expected to operate at altitudes above 6,000 metres this year. Developers anticipate that electricity generation at 3,000 metres could be cost-effective, comparable to traditional ground-based wind power generation, while at 9,000 metres, the systems could operate for over 8,000 hours a year, producing power at around 0.03 yuan per kilowatt-hour, which is less than half a US cent. China's 15th five-year plan for renewable energy includes the exploration and research of high-altitude wind power among other innovative wind energy forms. In addition to airborne systems, China is also exploring ground-based generators paired with flying devices to harness high-altitude winds. A 5,000-square-metre wind-catching canopy, claimed to be the world's largest, has been dispatched to a program led by China Energy Engineering Corporation, with power generation trials slated to commence by the end of 2026.",
  "summary": "China has flown an airborne wind energy system to 4,000 metres (13,123 feet) above sea level and generated electricity from the sky, in what state broadcaster CCTV described as a world first. According to a CCTV report on Saturday, the prototype S4000 craft completed a full work cycle – ascent, station-keeping, power generation and recovery – at a test site in northwestern China, which the…",
