Jeff Bezos has proposed building gigawatt-scale data centers in space within the next two decades, powered by constant solar energy to address AI’s growing power consumption demands. Speaking at Italian Tech Week, the Amazon founder argued that orbital computing infrastructure could eventually undercut the cost of terrestrial data centers while eliminating weather-related disruptions and energy constraints.
The big picture: Space-based data centers would leverage permanent sunlight and unlimited power generation to support the massive energy requirements of AI training clusters, potentially solving sustainability concerns plaguing Earth-bound facilities.
What they’re saying: Bezos emphasized the advantages of space-based computing infrastructure during his conversation with John Elkann, chairman of Ferrari and Stellantis.
- “These giant training clusters will be better built in space, because we have solar power there, 24/7. There are no clouds and no rain, no weather.”
- “We will be able to beat the cost of terrestrial data centers in space in the next couple of decades.”
Key technical advantages: Space offers several benefits that terrestrial sites cannot match for large-scale computing operations.
- Permanent sunlight availability eliminates the intermittency issues faced by Earth-based solar installations.
- Absence of weather disruptions means no interference from storms, clouds, or atmospheric conditions.
- Theoretically unlimited power generation capacity through continuous solar collection.
- Improved cooling conditions and fewer energy supply constraints compared to ground-based facilities.
Major challenges ahead: The vision faces significant technical and economic hurdles that could prove prohibitive.
- Hardware failures, upgrades, and maintenance would require expensive and risky rocket missions for each intervention.
- Replacement parts would be hundreds of kilometers away, making quick fixes impossible.
- Each launch depends on complex rocket missions where small malfunctions could jeopardize entire systems.
- The infrastructure would require highly autonomous systems capable of managing thermal regulation and Earth-to-orbit communication.
Blue Origin connection: Observers see Bezos’s own rocket company as a potential enabler of this orbital shift, though the company has yet to demonstrate the necessary reliability or capacity for continuous space construction projects.
Market context: Bezos compared the current AI surge to the dot-com era, suggesting that despite potential speculative “bubbles,” the societal impact of artificial intelligence will prove lasting and transformative for computing infrastructure needs.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment
The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
