Refrigeration consumes a significant amount of electricity. Dear Lazyweb, if someone out there knows the percentage estimate for the USA and elsewhere I’d appreciate an email from you. Gadolinium (Symbol: Gd) is a metal with some interesting magnetic properties. When placed in a magnetic field it heats up, then when the magnetic field is removed it cools down. Alloys of GD as well as other concoctions have magnetic properties strong enough to have a new method of cooling, which would be potentially more energy efficient than the familiar refrigerations system used almost globally today. Gd is also interesting because the cost, well today anyway, is not crazy — plus it has a Curie temperature that’s around room temperature. The familiar system where work is added …
