        During WW2, guards in the New York City subway system had a standing order to shoot on site anyone who came down a certain elevator holding a bucket of sand.

        The subway is powered by DC rather than AC electricity. Today solid-state converters are used. But back then, the only option was direct mechanical conversion. Literally a giant AC motor connected to a DC generator. An AC motor was powered by the grid, and its drive shaft was joined to the shaft of a DC generator, which energized the lines of the subway.

        But it represented a single point of failure. This one crucial machine was powering the whole subway system. And all it would take is one person throwing a single bucket of sand into the contraption to cause the whole NYC subway system to grind to a halt. Oh, and NYC was the primary port city for American troops and supplies going back and forth to Europe.

        I don’t think it’d even work. I wouldn’t be surprised if their cooling water is distilled in the process, so the salt would just get filtered out.

        On boats we literally use sea water to cool things and distill it on the ship. Data centers can surely do the same thing

            I mean they could be, but there’s nothing stopping the ultra rich from spending less than one dinners’ worth of money on a salt water distillation system for the money printer

              sure, but the corporations involved are hardly the most competent nor forward thinking actors :p

              money can buy you expertise, ofc, but often these people have an overinflated sense of their own abilities and think their expertise with computers extends into many other fields that it does not extend to :p

                I mean let’s be real, you have to use distilled water anyways if you’re using it to cool electronics. The odds that they are buying distilled water instead of distilling it themselves are incredibly fucking low given the fact that a water distillation system costs less than a server rack and buying distilled water is fucking expensive

                  they do not, they use evaporative cooling towers. i don’t think adding salt would make any difference to that either way though

          You underestimate how much billionaires cut costs. Water distillation? That could be 1 more gpu.

          There are some exploding rockets that can show you examples.
