The power crunch for AI data centers has gotten so severe that people — not just Elon Musk — are talking about launching servers into space so they can access solar power 24/7. One startup thinks the ocean is a better place for them. Offshore wind developer Aikido is planning to submerge a 100-kilowatt demonstration data center off the coast of Norway this year. The small unit will live in the submerged pods of a floating offshore wind turbine. If all goes well, the company hopes to build a larger version to deploy off the coast of the U.K. in 2028. That model will sport a 15 megawatt to 18 megawatt turbine that will feed a 10 megawatt to 12 megawatt data center. The move offshore could solve a few challenges. Proximity to power is an obvious one, since the source will sit overhead.…
