Data Centres in Orbit: Can AI Move to Space?
In November 2025, Starcloud put a single Nvidia H100 - the first data-centre-grade GPU ever sent to orbit - on a satellite called Starcloud-1. On 1 October 2026, Google followed with a prototype of its own, built with the imaging company Planet, carrying four Trillium-generation TPUs on a SpaceX Falcon 9 rideshare from Vandenberg.
This video asks whether putting AI computing into orbit can actually solve the problem ground data centres are creating - US data centres drove roughly half of all US electricity demand growth in 2025 (IEA), a large facility can use up to 5 million gallons of water a day (EESI), and a May 2026 Gallup poll found 71% of Americans oppose a new AI data centre near them.
In orbit, a solar panel in the right kind of path can see the sun almost continuously - Starcloud's own figures claim 5 to 8 times more usable solar energy than the same panel on the ground - and waste heat can radiate away to the -270C of space instead of needing water at all.
But cooling 10 megawatts of chips that way needs a radiator roughly the size of two football fields (Singularity Hub), nobody has flown one, and ordinary commercial chips are vulnerable to radiation-induced bit-flips in a way space-hardened chips are not. Starcloud's founder, Philip Johnston, says the economics only work if launch costs fall to about $500 per kilogram - a window he expects around 2028-2029, and only if SpaceX's Starship reaches a high flight cadence.
The verdict: a real, physically sound idea, moving at the pace of a handful of experimental satellites - plausible as a niche by the early 2030s, not a near-term fix for AI's power problem today.
Every figure is on screen with its source and date. Several claims (Starcloud's capacity-factor figures and its December 2025 Gemini claim) are the company's own, and the video says so.
