Sounds like a great idea. OTOH, impossible to calculate the damage to local ecosystems vs. traditional methods.

Totally uneducated guess: Probably better? Cooling is a major power suck, as well as consuming water.

Roughly 40 percent of the electricity consumed by an ordinary data center is for this purpose.

We’re draining aquifers that take thousands of years to build up. Don’t read up on that, it’s horrifying. So if we have to have data centers, I’m gambling that underwater is the lesser of two evils.
