Wouldn't it be cool if the music of the Grateful Dead could keep Cherry Garcia ice cream cold? This Earth Day, Ben & Jerry's announces the development of a working thermoacoustic refrigeration prototype - an environmentally friendly, alternative refrigeration technology that chills out to sound waves.


Three years ago, we began a company-wide audit of our refrigeration use and its adverse impact on the environment. The conclusion wasn't promising - from an environmental and safety perspective, today's refrigerants are not the answer for refrigeration systems in the U.S. Additional research led the company to Dr. Steven Garrett and his research team at Penn State. Sounds Cool! is a Broadband-only presentation featuring audio, video and animation that tells the whole story. We hope you like how we've brought this information to life.
