Rapidly expanding AI data centers are draining electricity and millions of gallons of water, prompting communities to push back. Some engineers suggest launching computing facilities into low‑Earth orbit, where solar power is constant and the vacuum eliminates conventional cooling needs. While space offers abundant sunlight, the physics of radiative heat loss means larger structures quickly become inefficient. Proponents therefore favor swarms of small satellites rather than massive orbital warehouses, but the crowded orbital environment raises collision concerns. The concept remains technically possible but faces steep engineering and cost hurdles. Read more →
