Air Conditioning That's Out of This World

Reducing air conditioning energy use by using new materials to enhance the cooling effects from outer space may not be such a far-out idea. In a simulation study, PNNL researchers found that daytime radiative cooling—the physical process by which an object loses heat to another object of lower temperature—could reduce energy consumption of an office building by 30 to 50 percent.

ORNL Refrigerator Cools With Magnetism, Not Freon

Some metals do a remarkable thing when they’re placed within a magnetic field: They heat up. Remove the magnetic field, and they grow cold. It’s not difficult to see how this heating and cooling, known as the magnetocaloric effect, might be put to good use.
