Wouldn’t a water treatment plant solve this, so water can be reused and they aren’t pumping it out of the ground, using it for cooling briefly, then dumping it? This idea of constant fresh water being used doesn’t make much sense to me.

They're taking advantage of inappropriately priced industrial water.

Regardless of if it makes sense, that's what they're doing. Using a lot of cold groundwater and then dumping it.

It would be much more expensive to have a closed loop of cooling water (and you're not going to get a lot of cooling on a humid 90 degree Iowa summer day)

Seems like northern Canada would be a good spot. Plenty of water and cold, and not many people to object to living next door. For most of the year they could just run the pipes outside to cool them down.

People say the same thing about Michigan, yet, here we are

[al_borland]

Averages in a place like Nunavut are below freezing 8 months of the year. Averages in Michigan are only below freezing 1 month of the year (according to wherever Apple Weather pulls their weather averages)

The population in Nunavut is 40,000 vs 10M in Michigan, despite Nunavut being 21x larger than Michigan. That ends up being 0.05/sq mi in Nunavut vs 174/sq mi in Michigan.

Northern Canada is much colder, has more fresh water, and has drastically lower population density, which should make it easier to find an area where people won't complain (other than environmentalists), and they would be able to better leverage nature for most of the year to help with cooling costs.

There aren't any roads to Nunavut, much less fat fiber pipes and gigawatts of electricity.

How do you capture and treat evaporated water? That is where data centers lose water, through evaporative cooling towers.

[al_borland]

Get rid of the cooling towers and condense the water, then treat like normal. Or put it into a closed loop with a radiator.

These are solved problems, I assume it’s just a question of cost and short-term vs long-term thinking.

It seems almost criminal that there are still so many people without safe water, and we’re using billions of gallons for temporary cooling of data centers, just to let it evaporate off.

Using a data center as a heat source for desalination may be another idea, where instead of data centers using fresh water, they could produce it. I looked into it briefly and it sounds like some universities and companies are exploring this. Instead of these data centers causing problems people want to avoid, they could solve problems people already have.

[colechristensen]

Evaporative cooling towers would be fine if it were a closed loop, the amount evaporated isn't worth that much concern. They're dumping ALL of the water that they intake after using it once. The evaporative or other cooling methods are just to lessen the environmental impact of dumping hot water back into the environment.
