G.E. Has Found a Way To Cool a Fridge With Magnets
At one time giant blocks of ice were the best solution we could come up with for keeping food cold. That primitive approach was eventually replaced by electric refrigerators using compressors and chemical coolants. Now, almost 100 years later, G.E. thinks it's found a better way to cool a fridge using a water-based fluid and magnets.
It's a radical departure from the technology we've relied on for almost a century, but the transition could be worthwhile since G.E. believes the system could be as much as 20 percent more energy-efficient than the appliance that's currently keeping your milk from spoiling. Which means an upgrade could help reduce your monthly power bill.
