Report: SpaceX - Powering AI from Orbit, Space Solar, and the Musk Stack (Pt.3) Summary * The Space DC is not a diffuse mesh of satellites spread around Earth — it is a constellation of tight orbital clusters, each functioning as a single coherent data center with nodes flying 20–160 km apart. * This tight-cluster geometry means 60–70% of all terminals by unit count are
Report: SpaceX - Powering AI from Orbit, Space Solar, and the Musk Stack (Pt.2) Summary * The bet is that AI compute has outgrown Earth — power, cooling, and land are all hitting walls — and 1.2 million satellites can host it in orbit instead. * Starship makes launch tractable, but cell chemistry is the real economic lever — HJT and perovskite tandems are what actually collapse the
Report: Soitec - Where Silicon Photonics Begins Summary * Near-monopoly on Photonics-SOI, the engineered wafer every leading silicon photonics foundry depends on as starting material. * Five compounding demand layers — cluster scale, optics-per-accelerator, SiPho share gains, scale-up optics, and memory disaggregation — all converging on the same wafer. * SiPho is becoming the default, winning on cost and volume today and
