Thermoacoustic Cooler Means Green-Friendly Icecream

MuddyRiverDoc writes "National Public Radio aired a story describing ice cream manufacturer Ben & Jerry's sponsored development of a thermoacoustic refrigeration technology, which uses helium gas subjected to ultra-loud 173 db sound to chill an ice cream cooler. The NPR interview and pictures of the Penn State researchers who did the development is available. There is also a brief description of the technique at the Penn State Live site and at the BBC, and an over-cute Ben & Jerry's broadband presentation, Sounds Cool!, that does however provide a useful diagram. Thermoacoustic refrigeration has been a focus of research for more than a decade at Purdue and elsewhere, and has reportedly flown on the Space Shuttle, but this prototype is reportedly the first that demonstrates the size, efficiency, and quiet operation that promises successful commercial introduction. Cool Sound Industries, Inc. is reportedly exclusively licensed for this thermoacoustic technology."

    So does this mean that noisy, drunken parties will be cooler than quiet, staid cocktail parties?

    Now I can buy that new kick-ass sound system without worrying about that new fridge my wife has been hounding me about and not feel guilty!

    Ever see people driving down the street with their radio so loud their car buzzes. They're pretty cool right?

    It also explains why I yell at those morons to "Chill out!", they just turn the volume up even louder.

    So they've taken "We all scream for ice cream!" literally?

    173dB is quiet? Was your previous job in the PR department of a CPU fan manufacturer?

    - How eco-friendly is the helium extraction process? Off the top of my head I believe it's fine, but are there any hidden eco-hostile effects in its production? Probably still far better than the method it replaces.

    - Have they experimented with different sound sources for the 173dB? Playing Barry White could produce seriousness smoothness...

    - Will they equip the Refrigerator Gnome that controls the internal light with OSHA-approved protective headphones, or will a generation of the little critters be doomed to deafness? (Don't laugh, I saw one of them in my 'fridge once after a Dead concert.)
