Musk 把 AI 算力的终极成本方案指向了太空，做 AI 基础设施或关注算力瓶颈的团队值得一看——如果成真，数据中心选址逻辑将被彻底颠覆。
Elon Musk 在 SpaceX 视频中阐述太空数据中心的成本优势：太空持续日照、无大气损耗，太阳能发电近乎零边际成本；真空环境散热无需风扇或水，能耗远低于地球数据中心。结合 Starship 的低成本轨道发射，Musk 预计 2-3 年内太空将成为 AI 算力成本最低的方案。最终，太空机架可扩展至太瓦级，经济性远超地球。

Elon Musk on the economics of space data centers.
In space, it's "always sunny", satellites get constant, high-intensity solar power with no night, clouds, or atmospheric loss, so solar arrays deliver near-continuous energy at virtually zero marginal cost.
Cooling is trivial: waste heat is simply radiated away into the vacuum of space (no fans, water, or energy needed, unlike power-hungry Earth data centers).
Combined with Starship’s cheap mass-to-orbit launches, this avoids building massive terrestrial power plants or fighting grid/land/cooling constraints.
Elon estimates that within 2–3 years, the lowest-cost way to generate AI compute will be in space.
Result: orbital racks of chips can scale to terawatts far more economically than on Earth.
