China's high-altitude wind power technology has achieved a major breakthrough, as the domestically developed S4000 Stratosphere Airborne Wind Energy System (SAWES) recently completed a test at a base in Northwest China, CCTV News reported on Saturday.
An upgraded version of the earlier S2000 SAWES, and the successful completion of its full-process flight validation marks the transition of China's stratospheric high-altitude wind power technology from the iterative development phase toward the engineering deployment phase, according to the report.
The test covered the entire process of ascent, station‑keeping, power generation testing, and smooth recovery, with all indicators meeting the required standards, fully verifying the system's reliability in complex and extreme high‑altitude environments, the report said. 
As an upgrade from the S2000 model, the S4000 adopts a new configuration with significantly improved overall performance. Its maximum operational altitude reaches 4,000 meters, making it suitable for deployment in the vast majority of regions across China. 
It can directly adapt to mainstream grid power supply requirements and has a design service life of up to 20 years.
Unlike conventional low-altitude wind turbines, which are often referred to as "windmills," the system employs a flying device.

短短十天,三场决赛,三次折戟。

B | 19岁的温瑞博本被视作国乒男队世乒赛的最大黑马,却用最残酷的方式为自己的成长交了一笔沉重学费。

C | 随着第二次队内选拔赛1比3不敌向鹏,这位曾接连挑落莫雷加德、张本智和的年轻人,彻底与伦敦世乒赛团体赛擦肩而过。三次冲顶,三次功亏一篑,温瑞博的惊艳,终究没能兑换成一张入场券。回看温瑞博的爆发轨迹,确实让人眼前一亮。重庆冠军赛上一路爆冷闯进决赛,他从配角一跃成为主角,教练组也顺势将他纳入重点培养序列。可到了决定命运的选拔赛舞台,这位年轻人却像换了一个人——首次选拔赛决赛1比3输给周启豪,第二次选拔赛决赛又以同样比分败给向鹏。

D | 半决赛还能上演0比2逆转的好戏,一到决赛就找不回节奏,这不是实力问题,是关键时刻的那口气,始终没能提上来。温瑞博的三连亚,也让主帅王皓的布局彻底落空。

E | 原本指着这位新星在梯队建设中挑大梁,结果新人顶不上来,老将又靠不住——梁靖崑在这次选拔赛中直接一轮游,连给年轻人制造压力的机会都没抓住。一边是希望之星频频在决赛门槛上栽跟头,一边是主力层状态起伏不定,王皓手里这把牌,打得比他想象中棘手得多。眼下国乒男队世乒赛阵容已定,温瑞博的遗憾与梁靖崑的低迷,像两面镜子,照出队伍新老交替的阵痛。从黑马到主力,差的从来不只是几场胜利,而是那种站在决赛场上、明知山有虎偏向虎山行的底气。温瑞博还年轻,这次栽了跟头不是终点,可对国乒男队而言,后续如何让年轻人真正扛住压力、让老将找回状态,才是摆在王皓面前最现实也最棘手的考题。
