Investors, including tech heavyweight Peter Thiel, are backing a radical new concept: sprawling artificial intelligence (AI) data centers that harness the power of ocean waves. The latest $140 million round is set to kickstart the build-out of these floating nodes near Portland, Oregon.

The idea? These submerged spheres convert wave energy into electricity for AI processing. They then beam their findings back via satellite—a potential game-changer in an era where land-based data centers are choking on power and space constraints.

Ingenious, or just salty? Benjamin Lee from the University of Pennsylvania sees promise. “It transforms a power transmission problem into a data one,” he says. But there's a catch: how well will AI thrive in water-saturated conditions?

Thermal efficiency could be a key advantage over land-based centers, as the ambient temperature is naturally lower and could reduce cooling costs. However, the challenges of maintaining equipment in harsh marine environments persist.

The true test: can these ocean-bound tech titans deliver speedier, greener AI solutions?
