Cooling with sound
A sound wave in a tube filled with gas can cool a refrigerator or a room. The technology that supports this idea is novel but proven, and it has the potential to eliminate a variety of harmful chemicals that destroy the ozone layer or increase global warming.
"Industry may be slow to change, and it certainly takes time to train experts in this area, but the potential for sound [thermoacoustics] to provide solutions is enormous.”
Steven Garrett, a 1993 Rolex Award Laureate, has been developing sound-powered refrigeration equipment for over a decade with the ultimate hope that this environmentally friendly technology will find its way from his laboratory to everyone’s homes.
