Oh cool! Yeah, having now worked in a switch facility for another company, as well as raised floor sites, concrete slab, and cooling similar to these is the way forward.

Liquid door also comes to mind.

I used to for for a company that uses self enclosed cabinets to avoid the use of floor AC units and isolate intense workloads. Scalematrix / DDC. Super interesting compared to raised floor. From what I can tell it's still kinda expensive, but the idea is promising.

Aren't contrails from wingtip vortesies? Or is it the engine exhaust?
