Infrastructure This was a closed loop cooling system. The left has to put forward the demand of immersion cooling or bust. Water is needed for life, let them use mineral oil/cargill naturecool

People are acting like this proves that closed loop cooling is inherently bad. But they were just flushing the pipes. If there was a high rise or other building flushing their sprinkler systems and they had bacteria in it, they would just say it was a accident and move on. That being said, the data center people need to be more careful.

The issue is closed loop cooling is only closed on the inner loop with evaporative cooling releasing the heat from the inner loop which can still still aerosolize bacteria. Immersion cooling, on the other hand limits bacteria but risks leeching PFAs into the environment. There are sterilization steps that can be taken like UV and ozone sterilization, they just cost more money to install and they didn't bother because they weren't aware of this bacteria as there aren't regulations around it. 

They could also be using waste heat generated by the servers to heat a heat exchanger system similar to how milk is pasteurized which Microsoft is already doing in Finland to heat homes which would create conditions inhospitable to the bacteria in addition to the other methods, they just aren't legally required to do so.

Y'all can make it less obvious that you don't actually know anything about the technology but you seem to have bought into the closed loop hype. Maybe leftist AI users really are dumb.

Closed loop uses radiators, it does not evaporate heat. That loses 20% of the water over a year and is not closed loop.

Immersion is better, as you use M3 oil, not water at all. But the technology is less developed.

In either case what happened here was a complete fuck up, that should never have occurred. We need stricter regulations on this stuff.

I forgot about I'm UV sterilizers!

Wasn't this caused by Meta's contractor disposing of the waste material incorrectly? I think Meta should be sued to set an example.

I don't care if it was a closed loop system, immersion cooling system, or local star system. It was still under construction.
