Space Data Centers
Terrestrial infrastructure is hitting hard limits. Orbital data centers utilize near-continuous solar power and passive radiative cooling to deliver scalable, sustainable AI compute.
The Terrestrial Bottleneck
🌍 Earth's Limits
Training next-generation AI models requires gigawatts of continuous power. Terrestrial grids are straining, permitting takes years, and the environmental impact of massive cooling systems (water usage) is becoming unsustainable.
- Grid constraints delaying deployments by 3-5 years
- Massive water consumption for cooling
- High carbon footprint if not strictly renewables-powered
🌌 The Orbital Advantage
Space offers a fundamentally superior environment for raw, continuous compute. Sun-synchronous orbits provide 24/7 solar irradiance, while the vacuum of space acts as an infinite heat sink for passive radiative cooling.
- 1366 W/m² continuous solar power in SSO
- PUE approaching 1.05 via radiative cooling
- Zero land use and zero water footprint
