A radically different technology that relies on magnets could dramatically cut the load. Most commercial coolers compress and decompress a refrigerant gas or liquid through a repeating cycle. As the refrigerant cycles, it draws heat out of the inside of a room or appliance. Compressors are energy hogs, however. And the most commonly used gases, when released, warm the atmosphere at least 1,000 times more than carbon dioxide does, molecule for molecule. Researchers at Astronautics Corporation of America in Milwaukee are developing a cooler based on magnets that eliminate the compressors.
