Instead of using water to cool CPUs in AI data centers, use piss.

The cooling systems are built to withstand saltwater unfortunately. Salt builds up and causes corrosion and blockages. So you would need a dedicated cleaning team or automated cleaning system, but that’s too much to ask from the trillion dollar companies for some reason; instead they’ll use potable fresh water that could have been used for drinking or farming.

What happens this water isn't usable again after? It's not destroyed, just heated

My understanding is that it is mixed with chemicals that enhance its ability to heat transfer, and thus becomes wastewater after it’s been used.

That seems unfortunately wasteful, but I guess it makes sense

Holy corrosion Batman. Even normal tap water is corrosive and will produce sediment given time. I don’t want my cooling system developing kidney stones.

A better method is closed loop with a water-coolant mix to prevent corrosion. Then a heat exchanger using a separate water source that can be of questionable quality but that system is easier to work on and can be made redundant.

My piss is hot, unless I drink too much Jamba Juice. Then it, and my diarrhea, are ice cold.

It would destroy the cooling system

Good luck finding a tech willing to fix it if it leaks.

I was just reading that they prefer to use treated water, on the other hand in Toronto they use lake water for cooling in the financial district Pretty sure they could use whatever if they had a financial incentive to.

They like to use distilled water because anything else leaves buildup on the cooling system. I’d imagine the lake water system is a different design than most datacenters.

OP’s idea with the salt and acidic content would probably not be great, either.

That in mind, actual liquid sodium can absorb a staggering amount of heat. Rather than a circulatory loop, though, I think it would have to work with a cyclical series of heatsinks, which for obvious reasons wouldn't work at the scale they need for AI processing.
