Have you ever wondered how much energy or gases your refrigerator consumes? The days of using refrigerant to cool down your food may be very well behind us thanks to some new technology. This cooling technology is based on magnetocaloric effect; that transfers heat from the interior of the fridge to the outside of the unit. The effect can be traced back to first being observed back way in the early 1900’s. With today’s technology and manufacturing breakthrough, refrigeration by magnets is almost possible thanks to General Electric.
