For centuries, refrigeration tech has stayed the same — energy-hungry and reliant on harmful gases. Enter magnetocaloric cooling: a new solution claiming to be 30% more energy-efficient than current cooling systems. And it’s scalable. From fridges to cooling buildings and server farms.

    What does that mean “refrigeration tech […] energy hungry”? The technical appilcation of the Carnot-Cycle is as close to maximum mathematical efficiency as we can get. Sure, it’s far from 100% efficient but we’re actively going against entropy here. In the end it all comes down to thermal isolation and losses. Even cheap fridges from the past 20 years take like 100 Watts once they’ve reached their target temperature. That’s only a bit more than a laptop and a bit less than a desktop computer on idle. AC-Units take a lot more but we already have a 100% efficency solution, it called “not bitching about the heat”.

    Seems like a dead end technology: they say it would be slightly more efficient in certain circumstances in future, but then that in those circumstances it still might not be…

    What’s the point of it over regular compressor cooling?
