Elon Musk on the economics of space data centers.
Rohan Paul Twitter · Rohan Paul (@rohanpaul_ai) · 2026-06-08
Elon Musk argues space-based data centers offer near-zero marginal energy costs due to continuous, unobstructed solar power in orbit and trivially simple cooling, making them economically compelling for AI compute.

Claims
- Satellites in orbit receive constant, high-intensity solar power with no night cycles, cloud cover, or atmospheric energy loss.
- Space-based solar arrays can deliver near-continuous energy at virtually zero marginal cost.
- Cooling a data center in space is trivially achievable compared to terrestrial facilities.
- The combination of free energy and easy cooling makes space a potentially attractive location for AI compute infrastructure.
Key quotes
In space, it's 'always sunny', satellites get constant, high-intensity solar power with no night, clouds, or atmospheric loss, so solar arrays deliver near-continuous energy at virtually zero marginal cost.
