Your current refrigerator is running on some pretty old technology. The compressor system inside has been the standard cooling force for around 100 years. It's about time for a change, and that change may be coming in the form of magnets.
Researchers at GE labs are showing off a prototype machine that runs a water-based fluid through a series of magnets. It's a new innovation that harnesses an old idea known as the magnetocaloric effect. The magnetocaloric effect describes what happens when certain kinds of metal alloys get hot when near magnets, and cool when pulled away.… Read more
