Thermodynamics 101: Space data centers can't shed heat, only radiate it
johnseach · x · 2026-11-04
Replying to Elon Musk's claim that "data centers in space look appealing," johnseach lays out the core physical problem: heat removal.
- Space is a vacuum — no air or water cooling; heat can only escape via radiation
- High-power servers generate massive heat that radiators struggle to dump
- The result: overheating, throttling, or meltdown risk
The author argues any space data center design must seriously account for thermodynamic constraints.
