A new type of heat pump being developed at Purdue University could allow residents in cold climates to cut their heating bills in half. The research, funded by the U.S. Department of Energy, builds on previous work that began about five years ago at Purdue's Ray W. Herrick Laboratories, said James Braun, a professor of mechanical engineering. Heat pumps provide heating in winter and cooling in summer but are not efficient in extreme cold climates, such as Minneapolis winters. "With this...

Your refrigerator's humming, electricity-guzzling cooling system could soon be a lot smaller, quieter and more economical thanks to an exotic metal alloy discovered by an international collaboration working at the National Institute of Standards and Technology (NIST)'s Center for Neutron Research (NCNR).* The alloy may prove to be a long-sought material that will permit magnetic cooling instead of the gas-compression systems used for home refrigeration and air conditioning. The magnetic...
