Novel fridge cools with sound

Sounds of 165 dB would cause a person's hair to catch fire from the frictional heating caused by air undergoing such intense compression and expansion.

lol, I thought that quote was quite amusing as well. I think if it could do that, I'd be more worried about other body parts (eyeballs, teeth, ETC...) :wink:

Not to mention the windows and glasses.

Still, this sounds like a cool idea. I'd be interested to know how energy efficient it is compared to a gas-based solution, since if it takes much more power to generate that sound than a regular fridge, the claimed environmental benefit would be pretty much negated by pollution caused by power generation.

The "flaming hair" issue isn't really a problem. The high db ratings are only achieved under pressure.

I was also interested in the part about increased reliability due to less moving parts. As for efficiency, lets get a reliably working prototype first :D

I'll let someone else beta test this baby, methinks...

Hehe. As long as they aren't $8k when they come out, I'll buy one.

I should think you need some higher frequencies for this to work, how do you reliable keep generating this frequency at this high level. Besides what's the lifetime of a fridge, think the gasses are a better target, ;-).

Higher than the 173 they've already attained? No idea... its certainly possible. This article is the first I've heard about cooling (or heating) with sound.

I think the main point was to reduce gases from being exposed to the environment. That is, a more environmentally friendly refrigerator.
