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.

。    DP 2.1已经和USB Type-C规范、USB4 PHY规范在底层打通，从而让DP、USB4接口共享通用的PHY物理层服务。同时，DP 2.1增加了新的DP带宽管理机制，再加上VESA的DSC(显示流压缩)编码、面板回放(Panel Replay)功能，可以实现在USB4连接上，DP隧道与其他I/O数据传输的高效共存。

二 | 其中，DSC编码可以将DP传输带宽降低67％以上，且不会影响画质，面板回放功能则可以将DP隧道封包传输带宽减少99％以上。ROG X670E主板已经把DP、USB4做到了一起DP 2.1还同步升级了数据线规范。首先是延长了长度，DP40数据线可以超过2米，DP80数据线也能超过1米，而且都不影响UHBR性能。其次，通过认证的DP40数据线通过，可以支持最高UHBR10 10Gbps，四条通道合并就是40Gbps；DP80认证数据线则支持UHBR20 20Gbps，四条通道合并最大80Gbps。在数据线的两端，都会有DP40或者DP80的标记，方便用户区分。产品认证与兼容性方面，VESA表示，DP 2.1保持向下兼容，而且此前所有通过认证的DP 2.0产品，都符合DP 2.1规范。产品支持方面，AMD将在下个月发布的RX 7000系列显卡，有望首发带来DP 2.1。目前，Intel Arc A系列显卡、AMD锐龙7000系列集成GPU，都已支持DP 2.0，NVIDIA RTX 40系列继续支持DP 1.4。

三 | Arc A已支持DP 2.0NVIDIA RTX 40还是DP 1.4。
