Google Project Suncatcher 探索将 AI 算力送上轨道
Google 真在琢磨把 TPU 塞进卫星上天，太阳能发电效率是地面的 8 倍，原型都要搭 SpaceX 火箭发射了，脑洞和工程细节都值得看看。
Google 的 Project Suncatcher 计划把 TPU 卫星用激光互联，组成轨道算力集群。据其测算，合适轨道上的太阳能板产能可达地面的 8 倍，可绕开地面电网与数据中心建设的瓶颈。首个与 Planet 合作开发的原型将搭载 SpaceX Transporter-18 任务发射。冷却、发射成本和卫星间可靠连接仍是待解决的问题。
I am sure that power supply, grid connections, and data center construction will be among AI’s biggest bottlenecks in the coming years.
Google’s Project Suncatcher explores an interesting possibility: moving AI compute into orbit, with TPU-equipped satellites connected by lasers.
Google says solar panels in the right orbit could be up to 8x more productive than on Earth, thanks to near-continuous sunlight.
It sounds crazy, but the potential is enormous: Scaling compute without waiting for terrestrial grid connections would be a major advantage. Cooling, launch costs, and reliable connections between satellites still need to be solved.
The first step is a prototype developed with Planet, scheduled to launch aboard SpaceX’s Transporter-18 mission.
SpaceX could end up being one of the biggest winners here. Making orbital compute economical would require affordable, frequent launches. That could turn the AI infrastructure boom into a major new source of demand for SpaceX.
