Researchers at the Technical University of Denmark have invented a new method of magnetic cooling technology that brings a whole new meeting to refrigerator magnets. Scientists have been able to drop the temperature of a room from 20° C to 11° C by taking the heat energy from opposing magnetic fields and thermodynamically reversing it to a cooler temperature. DTU researchers will use this technology to create a prototype refrigerator that cools itself using only magnets. According to research from Risø National Laboratory, magnetic refrigerators would be silent and their cooling cycles could be up to 60% more efficient than traditional refrigerators!

    […] I don’t get it either but it sounds interesting. If you want to read how it works go here. […]

    Almost all refrigerators run on magnets! The electric motors that power the compressors are magnetic machines.

    It’s impossible to ‘take heat energy from magnetic fields’. It’s magnetic energy by definition.

    Yes, the technology has some arguable advantages. But a huge disadvantage is that you have physically move the material between the heat sink and source. It can’t be connected to both at the same time and be expected to work. So it requires moving parts, will then make noise and ultimately the advantages are diluted.

    Comments on size, cost, material content? This is what’s really interesting.
