SpaceX - Powering AI from Orbit, Space Solar, and the Musk Stack (Pt.1)
Summary
* Terrestrial solar faces hard physical limits — atmospheric absorption, day-night intermittency, and ~25% peak efficiency — while space solar offers a roughly 10x advantage per watt delivered.
* Musk uniquely controls a self-reinforcing loop where xAI needs power, SpaceX needs payloads, and Starship needs a killer app — space-based AI data centers powered by space solar solve all three simultaneously.
* Every alternative path carries structural friction — nuclear's decade-long build
