谷歌推出“捕日者”计划，用聚光太阳能为轨道AI计算供电

Google has revealed Project Suncatcher, an experimental initiative that reimagines how large-scale computing could evolve beyond Earth’s surface. The project envisions space- based data centers powered entirely by solar energy, using orbital positioning to deliver continuous, carbon-free power for AI workloads. The program represents one of Google’s most ambitious research efforts yet—a convergence of aerospace engineering, artificial intelligence, and renewable energy design. By placing compute clusters in low-Earth orbit, the company aims to overcome terrestrial limits on land, cooling, and energy availability, while leveraging the uninterrupted exposure to sunlight that space offers. The concept also highlights a growing realization among major technology firms: the future of computing infrastructure may not remain confined to the planet. …
