Ben & Jerry's at it again
So
Ben & Jerry's is working on a way of using sound -- "thermoacoustic refrigeration" -- to make things cold. This method is much more environmentally friendly than typical refrigerants. Right now it will help keep their ice cream cold, but maybe some day soon it can help the rest of us keep our family refrigerators working, too. They have a handy dandy little
multi media presentation that explains how it all works.
