    Can someone explain why the data center use the water then expulse it as vapor instead of like recycling/ expulsing it as water? I get it that data center (hot) + water (cold) = vapor/steam but there could be a post processing to turn the steam to normal water but maybe that need regulation for that and it is a cost. Is that the only reason? Cost?

      Where would they dump the heat that the condensing water releases? If they had a good end point for the heat, they wouldn’t have to use the atmosphere for it in the first place.

          Water has a heat capacity that is 4 times more than air by weight. Water is far more dense at nearly a cubic meter per kg. Roughly 3500-4000 times more air by mass is required to perform the same cooling as evaporated water

    Why have they built them in the warm south and not the colder north?

      Cheaper energy maybe?

      But yes this would make way more sense in combo with long distance heat

    Has anyone actually read this article??

    1. It’s about electricity. Data centers are drying up the electricity that can be provided to a city and are causing projects like the electrification of the harbor to be delayed. There is no water shortage on a coast

    2. Data centers are built there due to submarine cables and the proximity to Frankfurt. There are like 20 cables landing at Marseille. That’s the best spot to put data centers if a lot of international traffic is expected.
