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.

    The link says ‘zero-emissions-cooling’

    The article sez: “It relies on the temperature change of materials called shape memory alloys (SMAs) when they are stretched and released.”

    How do you stretch something without producing any emissions?
