   Panthalassa and Samsung race to deploy floating AI data centers at sea

   Two competing projects aim to place massive, wave- or wind-powered data centers in open water to avoid land-based power and cooling limits. Panthalassa’s unanchored buoy design targets North Pacific AI workloads, while Samsung Heavy Industries is developing 50-megawatt floating units. Both focus on modular scaling and renewable energy integration, with pilot tests expected soon.

   What's confirmed:

   • Panthalassa, backed by investors including Peter Thiel, is developing unanchored, wave-powered floating data centers in the North Pacific to run AI workloads via Starlink.
   • The startup’s ‘giant lollipop’ buoy design aims to bypass land-based grid constraints, with a pilot series expected later this year.
   • Samsung Heavy Industries is designing 50-megawatt floating data centers at sea to address land-based power grid shortages and cooling challenges.
   • Both projects prioritize integrating renewable power, cooling systems, and modular scaling to meet rising AI demand.

   Still unconfirmed:

   • Aikido is separately testing a 100-kilowatt offshore demo unit under wind turbines.

   Panthalassa advances floating AI data centers in North Pacific with wave power, Starlink link

   Panthalassa, backed by investors including Peter Thiel, is developing unanchored, wave-powered floating data centers in the North Pacific to run AI workloads via Starlink. The startup’s ‘giant lollipop’ buoy design aims to bypass land-based grid constraints, with a pilot series expected later this year. Aikido is separately testing a 100-kilowatt offshore demo unit under wind turbines. Both projects focus on integrating power, cooling, and modular scaling for AI demand.

   What's confirmed:

   • Panthalassa is developing unanchored, wave-powered floating data centers shaped like ‘giant lollipops’ for deployment in the North Pacific.
   • The startup’s system will run AI chips using Starlink connectivity and is backed by investors including Peter Thiel.
   • Panthalassa’s pilot series of floating data centers is set for later 2026.
   • Aikido is separately testing a 100-kilowatt demo unit beneath an offshore wind turbine to merge power, cooling, and AI workload capacity.
   • Floating ocean data centers aim to reduce land use, lower cooling needs via seawater, and cut environmental impact compared to traditional facilities.
   • Modular, scalable designs and potential regulatory flexibility in international waters are cited as advantages for offshore AI data centers.

   Still unconfirmed:

   • The initiative is in early feasibility stages, with partnerships and technical verification needed to address environmental and maritime hurdles.

   Panthalassa Deploys Wave-Powered AI Data Buoys in Pacific; Aikido Tests Turbine-Linked Centers

   Two startups are advancing floating AI data centers to bypass grid power shortages. Panthalassa’s unanchored, wave-powered buoys—shaped like giant lollipops—will run AI chips in the North Pacific via Starlink, with a pilot series set for later 2026. Aikido is separately testing a 100-kilowatt demo unit beneath an offshore wind turbine. Both aim to merge power, cooling, and space for AI workloads.

   What's confirmed:

   • Panthalassa raised $140 million to develop floating AI computing nodes powered by ocean waves, targeting Pacific deployment later in 2026.
   • The startup’s Ocean-3 buoys will generate power from waves, run AI chips autonomously, and communicate with shore exclusively via Starlink.
   • Panthalassa positions its ocean-based data centers as a cheaper alternative to SpaceX’s proposed orbital server farms, leveraging natural cooling and renewable energy.
   • Aikido Technologies plans to deploy a small data center beneath a floating offshore wind turbine in 2026, combining power, cooling, and space for AI needs.
   • The AI industry’s power demand—including single training runs consuming electricity equivalent to thousands of homes—has accelerated interest in offshore and marine solutions.

   Still unconfirmed:

   • NetworkOcean reportedly seeks to sink GPUs into San Francisco Bay, though regulatory surprises and feasibility remain unconfirmed.
   • Panthalassa’s buoys may lack traditional anchoring or cabling, relying solely on wave motion and Starlink for stability and communication (specific design details unverified).
