Summary
AI data centers used about 415 terawatt-hours of electricity in 2024, and the IEA projects that could more than double to roughly 945 terawatt-hours by 2030, pushing Google, SpaceX and xAI to study solar-powered computing in orbit.
Google’s Project Suncatcher argues sun-synchronous low-Earth orbit could provide near-continuous sunlight and avoid grid, land and water constraints, but orbital systems still need massive solar arrays, radiators, shielding and communications hardware.
A 2026 feasibility study estimated a 1-megawatt orbital data center would require about 5,640 square meters of photovoltaic area and 2,500 square meters of radiator area, underscoring how cooling and launch mass drive costs.
Google said economics might approach terrestrial energy costs only if launch prices fall below about $200 per kilogram, while other research suggests current launch and spacecraft costs still exceed viable thresholds.
The most plausible early use is a specialized layer for satellite imagery, remote sensing and delay-tolerant AI tasks in space, rather than a near-term replacement for Earth-based cloud and AI infrastructure.

SpaceX’s 100,000-Satellite Gen3 Starlink Proposal: Ambition, AI Infrastructure, and the Future of Global Connectivity
Overview
SpaceX has submitted a bold proposal to the FCC for its Gen3 Starlink constellation, aiming to launch 100,000 satellites by July 2026. This marks a monumental leap in scale, setting a new benchmark for satellite internet infrastructure and reflecting SpaceX’s aggressive strategy to dominate the global broadband market. The Gen3 project is not just about expanding internet access; it positions Starlink as essential AI-era infrastructure, supporting advanced technological demands beyond traditional connectivity. This ambitious vision highlights SpaceX’s intent to redefine global communications and establish Starlink as a critical backbone for the future of AI and digital services.
