The funding round, spearheaded by billionaire investor Peter Thiel through his personal fund, also attracted investments from notable firms such as Gigascale Capital and Lowercarbon Capital, as well as tech entrepreneurs including Marc Benioff and Max Levchin.
According to CEO Garth Sheldon-Coulson, the capital will be allocated to finalize a pilot manufacturing facility in the United States and initiate the deployment of the first Ocean-3 computing nodes in the Pacific Ocean.
Innovative Ocean Data Centers
Panthalassa's autonomous platforms are designed for artificial intelligence applications, each spanning 85 meters in steel. These floating nodes will be strategically placed in remote areas of the Pacific Ocean, away from busy shipping lanes.
The deployment process involves towing the platforms horizontally before flipping them into a vertical position, allowing them to reach their designated sites without the need for motors, utilizing a specially engineered hull that captures wave energy.
Power for the onboard AI servers is generated through turbines that harness the ocean's movement, with data transmitted to clients via SpaceX's Starlink satellite network. This oceanic location also addresses cooling challenges by using seawater to manage heat, thereby increasing the longevity of the chips.
Panthalassa has already conducted real-world tests on several prototypes, including Ocean-1 and Ocean-2, with plans for a commercial launch of the full-scale Ocean-3 set for 2027.
Exploring New Energy Frontiers
The surge in investor interest is fueled by the escalating demand for computing power amid the AI revolution. As the market explores unconventional energy sources for data centers, Peter Thiel emphasized that Panthalassa is pioneering a "new oceanic frontier of computing." He highlighted the pressing need for new energy solutions as a reality rather than a mere concept.
Panthalassa's leadership believes that energy harnessed from the ocean could emerge as a significant clean energy source, potentially generating tens of terawatts of power, comparable to solar, wind, and nuclear energy. In a related note, it was mentioned that earlier this year, the Australian startup Cortical Labs unveiled a "data center" utilizing human brain cells.
