Sonic the Fridge Ogg

Improve cooling using sound waves inside fridges
  [vote for,

When it comes to equalising the temperature inside a fridge, air is a strange medium. Air is actually a pretty good insulator so some way of stirring the air molecules is needed to transfer the heat to the cooling elements.

Heat energy travels through air at about 30 m/s whereas sound travels 10 times as fast at 330 m/s. So cooling will be 10 times as fast with the addition of fast moving sonic air currents.

Ogg's containing the lyrics "Ice" and/or "Baby" sold separately.

The thing that's kinda similar to this idea but that actually works [notexactly, Feb 08 2019]


       Sound is energy so it would have to techno chill and I suppose egg cartons wouldn't be allowed.

       Ping-pong balls, of various colours could be inside the fridge, viewable by the glass screen on the front..

       So this works better in an atmosphere with higher mass like xenon...   

       Hey, higher mass gas steampunk earbuds featuring a continuous stream of xenon and/or helium for customized dynamic response...

       //fast moving sonic air currents// Alas no. Sound is a compression wave, meaning that the air molecules just wiggle back and forth a bit without much net movement.   

       Basing an entire product on a dubious pun is, as [8th] can confirm, an unrewarding exercise.

       //air molecules just wiggle back and forth a bit without much net movement//   

       The idea doesn't state but does rely on Duane Eddy currents that form around out of date condiment jars.

       Pyrophone...surprised the Borg ain't got one...

       //out of date condiment jars// Ah, there's your problem, [bigs]. Condiments should all be kept at room temperature; there's even words to that effect ("Refrigerate after opening") on most of them.   

       Seriously, who keeps ketchup in a fridge? And can mustard actually ever go off? I think not.

       //air molecules just wiggle back and forth a bit without much net movement//   

       Sound can wiggle enough to fracture expensive glasses and the molecules still have to hit each other under compression and decompression.   

       It would be interesting to chill air infront of a sonic cannon and read temperatures at said gun's target area. I am imagining the heat finding it easier to travel in the cannon's sound wave conduit than the untouched air.   

       //Thermoacoustics// Admittedly, the idea calls for music which is magnitudes of complexity compared to an attempt at a doof doof wave. The one thing with complexity is that it throws up anomalies.   

       Of course as [Maxwell] indicated, the fridge would need some heavy sound proofing.
