Silicon Valley bets $200M on AI data centers floating in the ocean
Panthalassa aims to test floating AI computing nodes in the Pacific in 2026.
Silicon Valley investors such as Palantir co-founder Peter Thiel have bet hundreds of millions of dollars on deploying AI data centers powered by waves in the middle of the world’s oceans—a move that coincides with tech companies facing mounting challenges in building AI data center projects on land.
The latest investment round of $140 million is intended to help the company Panthalassa complete a pilot manufacturing facility near Portland, Oregon, and speed up deployments of wave-riding “nodes” designed to generate electrical power, according to a May 4 press release. Instead of sending renewable energy to a land-based data center, the floating nodes would directly power onboard AI chips and transmit inference tokens representing the AI models’ outputs to customers worldwide via satellite link.
“Panthalassa’s idea transforms an energy transmission problem into a data transmission problem,” Benjamin Lee, a computer architect and engineer at the University of Pennsylvania, told Ars. “Performing AI computation on the ocean would require transferring models to the ocean-based nodes and then responding to prompts and queries.”
