A Magnetic Fridge with No Freon and No Compressor ⚡ экспресс
Original: "Magnetocaloric effect of Fe47.5Ni37.5Mn15 bulk and nanoparticles: A cost-efficient alloy for room temperature magnetic refrigeration"
Scientists have proposed a cheap alloy for magnetic cooling that works at room temperature.

An ordinary fridge is noisy, eats electricity, and uses harmful refrigerant. What if, instead of a compressor, we used a magnet? A new alloy of iron, nickel, and manganese cools itself when the magnetic field is removed. This is a step toward silent, eco-friendly fridges of the future.
🎯 Effect discovered in 1881 waited over a century for its moment: only cheap alloys could bring magnetic cooling out of the lab.
🎬 In Dune, Arrakis has no compressors—perhaps magnetic systems will one day become just as silent and unseen.
