Panthalassa raises $140m to develop wave-powered AI computing

Panthalassa has raised $140 million in a Series B funding round led by investor Peter Thiel to advance technology that uses ocean wave energy to power AI computing systems.

According to the company, the funding will support the development of offshore nodes that generate electricity from wave energy and run AI computing onboard. Data from these systems is transmitted via low-Earth-orbit satellites.

Panthalassa said the initiative responds to increasing demand for computing capacity and constraints faced by terrestrial data centres, including electricity supply, cooling requirements, and infrastructure limitations.

The company stated that its systems operate in offshore environments and use locally generated energy to power computing equipment, with ocean conditions providing cooling.

Panthalassa has previously deployed prototype systems and said the new funding will support completion of a pilot manufacturing facility and deployment of additional nodes, with commercial operations targeted for 2027.

Investor Peter Thiel said the approach expands computing infrastructure beyond traditional locations, while company representatives described the technology as a potential source of clean energy for AI systems.
