Training large AI models like ChatGPT and Gemini takes staggering amounts of power, which means an ever-growing demand for data centers.
But these massive server farms can’t always be housed in basic warehouses. From underwater chambers to buried sewage, companies are thinking outside the box (and the grid) to keep AI humming.
Here are five of the weirdest and most creative places where AI data is processed, cooled or offset, proving that the future of computing is not just unconventional, but sometimes downright strange.
1. Under the sea
Yes, there are AI servers on the ocean floor. Microsoft’s Project Natick ran a sealed steel data center 117 feet beneath the sea off Scotland’s coast for two years with no significant ecological impact reported, proving underwater cooling can slash energy costs and hardware failure rates.
China has since jumped in too, launching underwater AI data centers in Hainan, claiming benefits like higher energy efficiency and improved security.
Why go underwater? It's cold, it's quiet and the fish don’t complain about server noise.
2. Inside your poop (sort of)
As first reported by Tom's Hardware, Microsoft recently struck a $1.7 billion deal to offset its AI carbon emissions by burying slurry made from manure and human sewage 5,000 feet underground.
The company isn’t training models on excrement (thankfully), but it’s betting on bioslurry carbon removal to hit its carbon-negative pledge by 2030.
The company behind the effort, Vaulted Deep, says this prevents methane and CO₂ from escaping into the atmosphere. Microsoft calls it sustainability. But I'd call it...gross.
3. Within a secret mountain fortress
Tucked deep in the Swiss Alps lies the ultra-secure “Swiss Fort Knox,” a repurposed military bunker now housing sensitive data and cloud infrastructure.
Protected by steel doors and 24/7 surveillance, this fortress-style center can survive nuclear blasts, cyberattacks and possibly the apocalypse.
Bonus: the mountain’s natural chill helps cool the racks of AI servers running inside.
4. Underground tunnels and subway stations
In cities like Helsinki and Stockholm, old metro tunnels have found new life as data centers.
These subterranean spaces stay naturally cool and offer thick protection from environmental and electromagnetic interference.
Some U.S. companies have even converted abandoned mines and missile silos into cloud infrastructure hubs, a literal underground movement.
5. Floating on a barge
Google once explored data centers on floating barges powered by wave energy and cooled with seawater. The idea: mobility, ocean-based sustainability, and isolation from land-based hazards.
While the project never fully launched, patents and prototypes still exist and have inspired ongoing efforts by companies like Nautilus.
The takeaway
AI is reshaping the very places where computing happens. As model sizes explode and environmental scrutiny grows, expect even more unconventional data centers to surface (or submerge).
Whether it’s underwater, underground or buried in poop (ick), the future of AI might be weirder than we think.
