How would AI data centers in space even work? A former NASA robotics chief explains

【核心亮点】前NASA机器人主管揭秘：把AI数据中心送上太空，可能成为解决地球能耗和土地资源难题的颠覆性方案。【通俗解读】AI数据中心耗电巨大，在地球上既占用土地又产生大量热量。但太空是天然“冷库”，太阳能在真空环境中能量密度更高，还能避开地球上的政策限制和能源成本。这位专家设想，可以像建空间站一样，在太空轨道上部署模块化数据中心，通过卫星网络与地面通信，AI计算在太空中完成，结果直接传回地球。【实际影响】如果这项技术成真，未来AI服务的运营成本有望大幅降低——因为太空太阳能近乎免费，冷却也不用耗电。普通人用ChatGPT这类AI工具时，价格会更便宜，响应速度也可能更快。同时，地球上的土地和电力资源紧张能得到缓解，数据中心的碳排放问题也有望解决。不过，目前还面临火箭发射成本高、太空维护困难等挑战，但专家认为这并非遥不可及，就像当年互联网从实验室走进千家万户一样。
