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

    I was talking about cooling and a practical example of “working around the rules”.

    As for refrigeration in particular: any similar mechanism can do this too. Example: if you can figure out a material that emits IR in the ballpark for that specific range of wavelengths, you can use it as an active shunt.

    Also read somewhere before (not sure when or where tbh, but it might’ve been an old school 2000s forum discussion or something) about a way to possibly achieve it via phase change cooling at a molecular scale iirc. It wasn’t viable at the time and we made light of it, but with the material science advancements of today? Who knows. Maybe someone figured it out.
