# Space Solar Power Can Provide Continuous Baseload Energy

## Claim

Satellites placed in specific orbits — particularly **sun-synchronous orbits** in LEO — can achieve near-continuous exposure to sunlight, generating electricity 24/7. This makes them capable of providing the constant, uninterrupted *baseload* power required to run massive data centers for AI compute.

## Confidence: high (physics is sound; scale is uncertain)

## Supporting evidence

- Aetherflux materials explicitly describe *space-based solar power* and *continuous solar energy in space* as their basis.
- JLL: continuous exposure to solar radiation in LEO offers abundant, predictable power without grid interconnection or permitting friction.
- NTU Singapore's orbital data-center concept notes that space data centers *"would be powered by round-the-clock solar energy"* and wouldn't require batteries.
- Wikipedia on space-based data centers notes sun-synchronous orbits or related geometries as the standard architectural choice.

## Technical constraints (not yet defeaters, but real)

- **Launchable mass** caps available power per satellite, constraining computing density (Sener).
- **Thermal management:** radiative cooling is powerful but design-sensitive.
- **Radiation-hardened electronics** needed.
- **Reliability and servicing:** no easy repair in orbit; replacement cycles are unforgiving.

## Honest framing

The physical claim about near-continuous solar in appropriate orbits is **well-supported**. Calling it a *baseload* source for *in-space* workloads is reasonable. Using it to directly replace *terrestrial* baseload (i.e., beaming power down to Earth) is a far more speculative, longer-term proposition — and notably **not** what Aetherflux is proposing; see [[concept-space-data-centers]], which transmits processed data, not power.

## Open question
