Earth vs Moon: 20-Year Cost Analysis for Hyperscale Compute
The AI bubble is about to pop. Not just the market, the planet. Earth’s hyperscale data centers already burn 2% of global electricity and trillions of liters of freshwater. Nuclear plants are being built not for cities, but to keep algorithms cold. Meanwhile, 384400 km away, there’s a place with permanent cryogenic temperatures, no atmosphere, no water waste, and no land conflicts: the Moon.
Here is the 20-year cost comparison for a 10 MW deployment:
| Category | Earth (USD) | LQDC - Nuclear | LQDC - He3 Fusion |
|---|---|---|---|
| CAPEX | $0.1B | $20B | $20B |
| Energy | $0.18B | $5B | $0B* |
| Cooling | $0.08B | $5B | $5B |
| Maintenance | $0.10B | $2B | $2B |
| Personnel | $0.10B | $1B | $1B |
| Security | $0.02B | $0 | $0 |
| Communications | $0.005B | $5B | $5B |
| Launch and Assembly | 0 | $125B | $125B |
| Total (20 years) | $0.585B | $158B | $153B |
(*) Helium 3 mined from lunar regolith powers fusion with no fuel cost after infrastructure is in place.
The Moon is the only place in the Solar System ready to host cold computation at scale. Cryo by default. Radiation-free fusion fuel in the dust. Zero ecological backlash. What exactly are we still waiting for?
