Musk Pitches Space-Based AI Data Centers, Citing Cheaper Solar Power in Orbit

Elon Musk argues that declining launch costs have made space-based solar power economically competitive, opening the door to orbital AI compute that bypasses Earth's energy constraints.

In remarks captured by @cb_doge, Elon Musk made the case that space solar power now costs less than terrestrial alternatives when factoring in SpaceX's reduced launch costs — and that this makes orbital AI data centers economically viable. The argument: Earth-based AI training is increasingly constrained by power grid capacity and permitting timelines, while space offers unlimited solar energy with no land use conflicts.
