How magnets could change our fridges and ACs forever
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.
The concept behind mechanical refrigeration has been around for centuries, but it's a pretty big leap to say the tech hasn't changed. Energy-hungry is also a weird way to describe systems that can consume as little as 30-25% of the amount of energy they transfer. If heat pumps are energy-hungry, then magnetocaloric, consuming 20-17%, isn't really much less so.
30% improvement is great of course, but I guess I just don't like the framing of the introduction here.
