This startup just raised $140 million to build wave-powered AI data centers at sea

Panthalassa raised $140 million in Series B funding to advance wave-powered offshore AI data centers.

The company aims to move from prototypes to commercial systems that generate electricity from waves and cool servers with seawater.

Its ocean-based nodes will send compute results back to shore by satellite, reducing reliance on land and grid power.

If successful, the approach could ease energy and space constraints for AI infrastructure at scale.
