Comment on Tucson City Council votes 7-0, unanimously to kill AI Data Center

If nuclear power plants can manage it which would be easy for a server farm
Closed loop watercooling is really just air cooling with extra steps. The water is heated by the devices and cooled by a large radiator with fans. Or it’s cooled with a chiller which in turn is cooled by a radiator with fans.
Replacing the water is the most effective (yet wasteful) way to remove the heat.
To a point, yes. While you’re still using air to cool the water, I think it’s still a little more efficient than blindly keeping the server room at a low-ish temperature.
Keeping the server room cool is just using an air conditioner which is cooled by a radiator with a fan, and then using that cooled air to cool another radiator with a fan. Every step is a loss of efficiency.
The main advantage of water loops is that you get to use a different form factor for the radiator and fan by moving it away from the source of heat and aren’t limited by the case dimensions.

Because closed loops are more expensive in the short term, making it a non-starter

I guess water is cheep enough.
Still kinda obnoxious though. Like they couldn’t see that the ultra high water usage was the thing that would get the most pushback from?
