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.

    I thought the same thing.

    Seems they are mainly saying they developed cooling method that doesn’t rely on a greenhouse gas for a refrigerant. Not nothing.

    …and if you stretch and release something off solar/wind power greenhouse emissions will be very low indeed.

    I’m curious about lifespan of these systems. I don’t know much about SMAs, but my intuition says they degrade. Am I wrong? I hope I am :)
