Floating ocean AI data centers

Startups are building large, wave‑driven platform 'nodes' that house AI accelerators, use seawater for cooling and onboard wave turbines for power, and send model outputs to customers via satellite links. Investors have poured tens to hundreds of millions into prototypes (Panthalassa's Ocean‑3 is due for testing in 2026) as a way to avoid land permitting, grid limits and freshwater cooling needs. — If adopted at scale, ocean‑based AI compute would shift infrastructure siting, create new maritime regulatory and security questions, and reconfigure energy, cooling, and data‑transit politics.
