Keep it Cool with no Energy

The other day in Vancouver I was discussing the inefficiencies of refrigeration and now it seems kinda freaky that the headline “MAGNETIC REFRIGERATOR NEEDS NO ELECTRICITY” appeared on my monitor the next day. To get straight to the meat of the matter:

The new method uses opposing magnetic fields to increase the temperature of the materials employed. The heat energy is transported through a non-volatile fluid, such as water, and then thermodynamically reversed to a cold temperature. The scientists have already been able to cool a 20° C room to 11°C using the new technology.
