Silicon Valley's relentless demand for AI computing power is now looking to the deep ocean for solutions. A startup named Panthalassa has secured $140 million in funding, led by prominent investor Peter Thiel. The company's ambitious plan involves using wave energy to power massive data centers floating at sea, providing electricity directly to AI chips in the middle of the ocean. Following this funding round, Panthalassa's valuation is approaching $1 billion.
According to reports, Garth Sheldon-Coulson, Panthalassa's co-founder and CEO, stated that the new capital will be used to scale up pilot manufacturing facilities, with the goal of commencing commercial deployment next year. The investment round attracted several major figures from the tech industry, including Salesforce CEO Marc Benioff, PayPal and Affirm co-founder Max Levchin, and early Google and Amazon investor John Doerr.
**Wave-Powered, On-Site Computing: Panthalassa's Ocean Solution**
After a decade of research and development, Panthalassa's core technology harnesses the up-and-down motion of waves to drive water through turbines, generating electricity to power AI chips. The company's ocean "node" structures stand approximately 85 meters tall, comparable to London's Big Ben or New York's Flatiron Building, with most of the steel structure submerged below the waterline. Sealed compartments house AI servers, which are cooled by seawater. The nodes require no engines and can navigate to target ocean areas autonomously, aided by their hull design. AI chips receive and respond to user requests via SpaceX's Starlink satellite connection.
Unlike previous ocean energy concepts, Panthalassa's nodes are not connected to the seabed or land; electricity is used directly at the point of generation, eliminating the need for transmission to shore. Sheldon-Coulson emphasized that this design differentiates it from all prior ocean energy attempts and is a crucial prerequisite for achieving large-scale deployment.
**Minimalist Design, Earth-Friendly Materials: A Team of Ex-SpaceX Engineers**
Panthalassa's node structures adhere to a "minimalist" principle—featuring no hinges, flaps, or gearboxes. This design significantly reduces the risk of failure in harsh marine environments and also facilitates mass production. Headquartered in Oregon, the company plans to build pilot manufacturing facilities in the United States, with the final location dependent on fleet deployment sites. Sheldon-Coulson noted that the structures use only abundant, earth-friendly materials like steel, ensuring a robust supply chain and rapid manufacturing. The nodes operate with closed-loop water circulation, have no emissions or engines, and pose minimal impact to marine life.
The Panthalassa team comprises former engineers from SpaceX, Boeing, NASA, Tesla, and Apple. Co-founder Brian Moffat previously worked at Disney Imagineering and Google, while Engineering Director Dan Place contributed to SpaceX's reusable rocket "drone ship" project.
**The AI Energy Race: The Ocean Emerges as a New Frontier**
The persistent gap between AI computing demand and supply is fueling investment in unconventional energy solutions, ranging from restarting decommissioned nuclear plants to launching solar-powered data centers into space. Sheldon-Coulson, a former AI and energy researcher at hedge fund Bridgewater, believes wave energy stands alongside wind, solar, and nuclear power as one of the few clean energy sources capable of generating "tens of terawatts" of power. He describes ocean waves as "sunlight, twice concentrated"—driven by wind, which originates from solar heat, and persisting even after the wind subsides, effectively acting as a "battery for sunlight" that can be captured continuously.
Peter Thiel participated in this investment through his personal fund. He has previously supported "seasteading," a libertarian project to establish autonomous communities in international waters. His venture capital firm, Founders Fund, had already invested in an earlier funding round for Panthalassa back in 2018. Thiel commented, "Future demand for computing power will be unimaginable. Extraterrestrial solutions are no longer science fiction; Panthalassa is pioneering the oceanic frontier."
