Nov 12, 2026 - AI Data Centers in Space: The Catch Behind “Free” Power



AI data centers in space promise abundant solar energy. But keeping their chips cool is much harder than it sounds.
This documentary follows the engineering from sunlight to useful computing: solar arrays, orbital placement, batteries, radiators, laser links, launch costs, and reliability. We look at Google`s Project Suncatcher experiments and explain the gap between answering a prompt in orbit and operating a commercial data center continuously.
How much panel area could a one-megawatt load need? What happens in Earth`s shadow? And where does all the heat go? Clearly labeled hypothetical calculations make the tradeoffs tangible without treating a concept as a finished product.
