Microsoft has rolled out closed-loop liquid cooling at some newer facilities, filling water once and recirculating it instead of topping it up. Meanwhile, copper interconnects that move data between GPUs are hitting physical limits, losing signal strength over distances past two meters, so some operators are paying up to 7 times more for optical interconnects and co-packaged optics instead. On the grid side, transformer wait times have stretched from 6 to 12 months in 2020 to two to four years now, even as the industry added 30 GW of data center capacity worldwide between 2021 and 2025.\n\nThis is the real ceiling on AI's growth curve, not GPU production. Chipmakers can ship accelerators faster than utilities can build substations or transformer factories can clear backlogs, which means compute capacity is now gated by power delivery and plumbing, not silicon. That shifts leverage toward whoever can pre-book grid connections and cooling infrastructure years in advance, likely entrenching the operators that already have the balance sheets to do it.\n\nNone of this gets solved by a breakthrough. Solid-state transformers and photonic links are incremental engineering, the same kind utilities and telecoms have been grinding through for decades, just now priced at AI-boom urgency.","[\"data-centers\",\"cooling\",\"power-grid\",\"ai-infrastructure\"]","2026-10-11T17:20:00.000Z","2026-10-11T18:23:29.005Z","2026-10-11T18:23:33.466Z","published",null,[],"hardware",[26,27,28,29],"data-centers","cooling","power-grid","ai-infrastructure",[31],{"name":32,"url":33},"TechRadar","https:\u002F\u002Fwww.techradar.com\u002Fpro\u002Fpowering-the-ai-revolution-inside-the-grid-thermal-and-interconnect-challenges-limiting-data-center-growth",0,{"sections":36},[37,42,47,52,57,60,65,70,75,80,85,90,95,100],{"name":38,"slug":39,"count":40,"latest_published_at":41},"AI","ai",6858,"2026-10-11T18:33:56.000Z",{"name":43,"slug":44,"count":45,"latest_published_at":46},"Security","security",945,"2026-10-11T13:15:09.000Z",{"name":48,"slug":49,"count":50,"latest_published_at":51},"Policy","policy",496,"2026-10-11T20:06:43.000Z",{"name":53,"slug":54,"count":55,"latest_published_at":56},"Deals","deals",484,"2026-10-09T12:30:00.000Z",{"name":58,"slug":24,"count":59,"latest_published_at":18},"Hardware",234,{"name":61,"slug":62,"count":63,"latest_published_at":64},"Science","science",196,"2026-10-11T15:34:40.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Consumer Tech","consumer-tech",189,"2026-10-11T19:56:28.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Startups","startups",120,"2026-10-09T17:02:31.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Software","software",115,"2026-10-11T07:34:45.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Dev Tools","dev-tools",110,"2026-10-09T13:03:48.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"General","general",70,"2026-10-11T14:15:00.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"Gaming","gaming",59,"2026-10-09T11:43:43.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",34,"2026-10-08T14:00:22.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
