University of Zurich physicists have developed an amazingly simple device that allows heat to flow temporarily from a cold to a warm object without an external power supply. Intriguingly, the process initially appears to contradict the fundamental laws of physics. If you put a teapot of boiling water on the kitchen table, it will gradually […]

A Louisiana State University (LSU) research physicist team has discovered a breakthrough magnetocaloric material that cools. The press release believes food refrigeration and air conditioning may become more efficient and environmentally friendly thanks to the patent-pending work of physicists. Lead researcher LSU Physics Professor Shane Stadler said, “The world refrigeration market is expected to increase […]

The Ames Laboratory at Iowa State University hosted a magnetic refrigeration conference that drew an international audience in Des Moines Iowa on May 12, 2009. The focus of the four-day event was on an energy efficient form of refrigeration that replaces gas compressors and ozone-depleting refrigerants with a system that uses special alloys and a […]

Imagine a refrigerator, air conditioner or other compressed gaseous system that has no more coils, compressors and controls. Penn State‚Äôs Qiming Zhang is offering that his research is yielding a refrigeration technique that is based in ferroelectric polymers. Ferroelectric polymers exhibit piezoelectric and pyroelectric effects that are usually encountered in certain single crystals and ceramics. […]
