Rohan Paul@rohanpaul_ai · XElon Musk 在 SpaceX 技术更新中指出，太空“永远晴天”，太阳能持续高功率且近乎零边际成本；真空环境仅靠辐射散热，无需风扇或水。结合 Starship 低成本入轨发射，可避免建造地面电站或受制于电网、土地、冷却限制。他估计 2–3 年内，太空将成为产生 AI 算力成本最低的方式，能经济扩展至太瓦级芯片集群。SpaceX 已具备大规模制造、发射、运营 AI 卫星的能力。
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.
