Researchers have built the first refrigerant-free system to reach sub-zero temperatures, a breakthrough that could reduce food waste and greenhouse gas emissions.

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 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.
