Overview

• Speaking at Italian Tech Week in Turin, Jeff Bezos said continuous solar power could make space-based training clusters cheaper than Earth facilities in 10–20 years.
• Reporting flags difficult maintenance, costly launches and failure risk, while ISS trials by HPE and Axiom have been tiny and have exposed reliability issues.
• Tom’s Hardware estimates a 1 GW orbital system would require roughly 2.4–3.3 million square meters of solar panels weighing 9,000–11,250 tonnes and launches costing tens of billions of dollars.
• The Register notes that rejecting about 1 GW of heat would demand vast radiator arrays and that radiation hardening beyond standard ECC would be necessary.
• Latency would constrain many applications at roughly 20–40 ms from low Earth orbit and up to about 600 ms from geostationary orbit, though AI training could be more suitable.
