Tech billionaires are exploring space- and ocean-based data centers to bypass Earth’s limits on energy, regulation, and infrastructure.
Elon Musk is advancing a plan to deploy massive AI data centers in orbit, potentially as large as a Boeing 747, at around 600 km altitude. The concept relies on constant solar exposure, offering effectively continuous energy supply without terrestrial constraints. The initial goal targets 1 gigawatt (GW) of computing power by 2027, with long-term ambitions reaching 1 terawatt (TW).
Achieving this requires major breakthroughs, including full deployment of Starship, large-scale space-based chip manufacturing, and billions of dollars in investment. The logistical complexity of assembling and maintaining infrastructure in orbit remains a significant barrier.
In contrast, Peter Thiel has backed Pantalassa with $140 million, valuing the company at around $1 billion. Its approach places floating steel structures, roughly the length of a football field, in the Pacific Ocean to host AI compute systems.
These ocean platforms harness wave energy, positioning themselves as both renewable and abundant power sources. Cooling is handled naturally by seawater, eliminating one of the biggest constraints faced by land-based data centers.
Both approaches respond to growing bottlenecks on land: limited access to gigawatt-scale power, long permitting timelines, heavy water usage, and local opposition. Offshore and orbital solutions avoid these issues, along with traditional grid dependencies.
Current ocean-based systems are primarily used for running AI models, not training them, indicating the technology is still in early deployment phases compared to terrestrial hyperscale centers.
A critical shared feature is that both outer space and international waters operate largely outside national jurisdiction. This raises questions about governance, accountability, and control over increasingly powerful computational infrastructure.
Space and ocean data centers reflect a shift toward infrastructure beyond national borders, driven by energy demands and regulatory limits, but they introduce unresolved technical and governance challenges.
