Imaging if this technology could cool a data centre.

Edit: I was not involved in this project. You are wasting your time asking me questions.

    That’s thermodynamically impossible but ok.

    When you cool something you take heat energy out of it you have to do something with that heat energy you can’t just delete it.

      You don’t overcome thermodynamics, but you can work around them. For example:

      When you cool something you take heat energy out of it you have to do something with that heat energy you can’t just delete it.

      Or you can shunt it into space so that it doesn’t heat the atmosphere on its way out. That’s called radiative cooling and it’s brilliant.

      And it can be done at home with household items. See Nighthawk’s YT channel for more info: https://youtu.be/N3bJnKmeNJY

      And that’s just one out of many possible approaches. Interesting read: https://en.wikipedia.org/wiki/Reflective_surfaces_(climate_engineering)

        That’s reflection of external heat not removal of internal heat. Refrigeration requires effort and therefore energy.

        That’s also impossible. Anything that does work generates heat, it’s a fundamental law of thermodynamics.

        There is no such thing as a thermally neutral mechanism, because all energy is eventually thermal. You can reflect heat, as in you can prevent heat from being added into a system via thermally neutral mechanisms but you can’t remove it without exerting energy.

      Seriously this! I feel like that cobra chicken meme where I’m yelling

      “where does the entropy go?”

      “WHERE DOES THE ENTROPY GO‽”
