Opus 5.5 builds a liquid-cooled AI hall 3D scene from a text prompt
A plain-text prompt had Claude Opus 5.5 generate a Three.js 3D scene of a 20-rack liquid-cooled AI hall that opens in any browser, where layout changes take a single sentence.
20 RACKS. 1,440 GPUs. HOW MANY US HOMES WORTH OF POWER DOES THIS ROOM DRAW? About 2,000. 3D build of a small liquid-cooled AI hall. Illustrative, 20 racks of NVL72-class (72 GPUs per rack). Each rack pulls roughly 120 kW. A typical colocation rack is 8-15 kW. One of these = 8-15 normal ones. Air can't pull that much heat out of such a small box. So cold plates sit right on the chips and liquid does the work. Rough math: 2.4 MW at full load, 24/7 = ~21,000 MWh a year At $0.08/kWh (assumed) = ~$1,700,000 a year in electricity Racks alone, reported ~$3,000,000 each = ~$60,000,000 The scene itself was made by prompting Claude Opus 5.5 in plain text. No Blender, no 3D software. It runs in the browser (Three.js) and the result is one link that opens on any laptop or phone. Changing it takes one message: "make the row shorter", "add a cooling loop". Useful at concept stage: show a client how racks, power and cooling fit in a room before anyone opens Revit. Same approach works for a plant room, a pump station or a warehouse layout. It is a sketch you can walk through. Real design still lives in BIM.
