The laws of thermodynamics? Can't create or destroy energy and overall entropy increases over time. A closed loop (or any cooling system) just moves heat away from the hot thing. So yes, they can be used as much as any other cooling system but it won't stop the issue of "generating lots of heat". That heat still needs to go somewhere. Dumping it into the atmosphere might be the best option if there's nothing in the area that needs heat. Should probably build them next to steel plants or something like that. Then a closed loop would be better.
I never said it fixed the issue of generating heat. Heat isn't really a major problem as far as I am concerned. I thought we were talking about water use.
Fair enough, I thought we were talking about the heat lol.
? OP was claiming that the majority of data centers use closed loop/refrigeration systems and I was pointing out that US data shows the vast majority use evaporative cooling. They posted a few comments pushing that idea which is why I refuted that. I’m not sure what the point you’re trying to make is in regards to those two statements. I’m not disputing the accuracy of what you’re saying, just unsure of where you’re going with it.
Thought your request to back it up was in response to the parent comment saying that condensing the water defeats the purpose rather than the first paragraph.
