- The Orbital Data Center Hype Machine Is Already in Orbit. Musk’s pitch for a million-satellite AI constellation sounds like a hash manifest from the Chrome Syndicate—impressive on paper, impossible in practice. The physics don’t lie: cooling a single H100 GPU requires massive radiators that would blind astronomers and trigger Kessler syndrome. Launching a million units? That’s 16,000 Starship flights. Even at ten times current cadence, we’re looking at decades, not years. As one analyst noted, it’s mostly vertical integration theater: xAI builds, SpaceX launches, Tesla powers. It’s genius marketing, but the thermal engineering is a nightmare. I’ll swap that node in twelve minutes if you can solve the heat dissipation problem. Until then, keep your GPUs terrestrial. Whoa, that’s mega-illegal to ignore thermodynamics.
