Everyone's got a hot take on data center water use, and most of them are garbage. This week Jacob and Igor skip the outrage and give you seven questions to help you decide whether a given data center is something you're on board with: where it's built, how it's cooled, where the power comes from, who owns it, and who's footing the bill (you'll have to listen for the other two). They test them against SpaceX's Colossus facility in Memphis, unpermitted gas turbines, a drought-prone aquifer, and a stalled water recycling plant included. The guys also get into why "zero water consumption" claims can be misleading once you understand the difference between withdrawal and consumption. Plus: a bonus rant on why data centers in space aren't happening anytime soon.
