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.

    But the reason why most of that food is thrown away is not lack of refrigeration, cheaper refrigeration will not solve that problem.

    I think “cheaper refrigerators” is an oversimplification. People without access to a functional refrigerator often have bigger problems than a mere absence of a single appliance.

    But the energy savings is a big deal. We’re not just talking about food refrigeration but AC, which is a much bigger deal especially as we suffer a warning planet

      I agree, but that has little to do with food waste.

      Moreover, I doubt this is more efficient than traditional refrigeration. But I’d be happy to be wrong on this.
