Depending on the orbital plane, the system is expected to remain solar-powered for more than 99 percent of its operations
99%以上时间太阳能供电 + 辐射散热，是轨道数据中心相比地面的核心竞争优势。地面数据中心的 PUE 通常在1.2-1.5，即30-50%的电力用于冷却；太空中辐射散热无需额外能耗。如果技术成熟，这是真实的效率优势。

When the project is complete later this year (all done while the existing data center remained in operation!), the data center's annual PUE will drop from 1.5 to 1.2, saving 20 percent of its annual electrical cost.
