"We did it, Patrick! We made a technological breakthrough!"
A place for all those who loathe AI to discuss things, post articles, and ridicule the AI hype. Proud supporter of working people. And proud booer of SXSW 2024.
AI, in this case, refers to LLMs, GPT technology, and anything listed as "AI" meant to increase market valuations.

What do you mean by "evaporation cooling"? A fraction of the water evaporates to provide cooling, a fraction is discharged as purge to prevent solute accumulation, and the rest is recycled? I thought the main reason that datacenters consume as much water as they do is when they don't recycle the water, and just use it once and then discharge it (no evaporation at all).
Maybe I'm misinformed but I am close to someone that designs them. He said evaporation cooling is cheaper, closed loop systems are more expensive.
