    "earlier this year, a team at General Electric, led by engineer Venkat Venkatakrishnan, announced it had built a desk-sized device that could reduce temperatures by 80 degrees Fahrenheit. GE solved what had been a decades-long problem by combining a 50-stage cooling system (think of a piece of metal descending down a giant staircase of magnets, where each step lowers the temperature of the metal just a bit—about 6 or 7 degrees Fahrenheit) with the development of a new type of iron-manganese alloy that has strong magnetocaloric effects, even at room temperature. The GE team predicts its system could improve a standard refrigerator’s energy efficiency by about 30 percent and eliminate the environmental problems that come with producing and disposing of refrigerants."

    Because a front for Chevron is paying for it. Check out Energy Public Square (@EnergyPS): https://twitter.com/EnergyPS?s=09
