24/7 Lecture: Magnetic refrigerators

Posted on Tuesday, April 28, 2020 by for 24/7 Lecture.


24 seconds: Conventional refrigerators, the ones that you use at home to keep your food cold, are actually harmful to our environment in the long run. Upon disposal, they release hydrofluorocarbons into the atmosphere and largely contribute to global carbon emissions. A viable substitute to a conventional refrigerator is a magnetic refrigerator. It operates without the use of these harmful gases and instead utilizes magnetic phase transitions to achieve their cooling effect. Magnetic phase transitions need to be studied to improve existing magnetic refrigerators and make current models more energy efficient.

7 words: Magnetic refrigerators are cool without carbon emissions.
