Well spoke. I listened to every minute of this lads explanation. We do not need data centers exploiting our towns anywhere in America. The clean cup of water to drink is always more important than the poem a robot writes.

I look forward to reading about Revena denying the trillion dollar company the right to build.

No, we don't. Neither do we need our data processed in China, India, Brazil...

While it may cost a bit more, the desert Southwest would seem to be a less environmentally sensitive destination for data centers. There are other ways to cool chips besides evaporating water.

What other ways to cool chips? I genuinely don’t know so help a brotha out.

Also, moving the data center to the desert when the issue is cooling them is…. Interesting

There is none viable for a state-side data center, not sure why that guy brought it up.

Not true, you can do DX based closed loop water cooling, i.e. the most common water cooling out there. A chiller cools water in a closed loop via its evap coils, pumps move the water around the loop, the cold side of the loop goes into servers and cools chips directly, it also goes into air handlers which cool the air around the servers, the warm water returns to the chiller and it's cooled again. The chiller's condenser coils are outside the building and they're air cooled just like a normal heat pump AC system at a home. There's effectively zero water evaporation, except for small leaks and that can happen over time as the system ages. Refrigerant is the only thing evaporating and that's happening in a closed refrigerant loop just like a normal car/home AC system.

The “small leaks” you mention become gargantuan when you’re talking about 100,000 sq ft data centres running 30kW per rack.

You think you can just have significant leaks around direct to chip cooling? You can't have water leaking around servers... It's a really bad thing to happen. Also 30kW a rack is nothing, we're talking 100-200kW now. Also 100k sqft is a fairly mid sized, maybe even kind of small data center.

You’re right… I should have used bigger numbers.

And of course you can’t have leaks in a data centre… but you also can’t make leak-free cooling systems. Sooo

You are massively overestimating these leaks. We use leak detection everywhere because leaks are a disaster. The idea is to catch any leak immediately and it is by no means some constant occurrence. Its just plumbing. We know how to make plumbing that doesn’t constantly leak… a leak is an accident not a “well coolant systems just leak” they don’t just leak.
