(With a large nod to bigsleep, please direct any buns
in the direction of bigsleep)
A chest freezer which has a metal plate (hermetically
sealed (ho ho)) on the top with metal compartments
going deep to shallow. There's a glass panel on one
side.
The deep end is for stuff that's actually
to be frozen,
to the not very deep for the salad tray.
The Mercury is in a frozen standing wave, with more
of the stuff around the deep compartments and vice
versa.

Standing waves in a wave tank
https://www.youtube...watch?v=NpEevfOU4Z8 Starts with a traveling wave from the wave generator. This sets up a standing wave around 0:50. Some traveling waves are seen later in the video, too, when they turn the wave generator off and also at the start of the second run. [notexactly, Feb 07 2019]

I'm with you so far, and I know what a standing wave is, but I have no idea how this is supposed to function as a freezer or make a freezer behave differently. |
|
|
Well-spotted that entity. |
|
|
It's a standard heat pump jobbie, with heat exchanger
to cool the liquid mercury. Mercury has a freezing
point of -38 degrees, so a reasonably good freezer. |
|
|
And you can watch the wave. For a change, you could
put in some red mercury. |
|
|
Are you imagining a standing wave as producing a static
slope of mercury, deeper at the cold end? |
|
|
Sort of, but the gradient of cooling is produced by
distance from the bottom of the compartments. |
|
|
I knocked up a diagram, with one cheat - the actuator
is sonic, and does the cooling as well, with a boring
old freezer heat pump. |
|
|
I don't understand why the mercury needs to be in a standing wave, or how the standing wave is maintained |
|
|
//Are you imagining a standing wave as producing a static

|
|
You'd have to watch it under a strobe light of the right
frequency to make it hold still. |
|
|
//a static slope of mercury, deeper at the cold end// - another way to produce this effect is to mount your mercury-filled chest freezer on a handy centrifuge |
|

(sighs) according to Neal Stephenson's
Cryptonomicon it is perfectly easy to make a
standing wave in mercury, Waterhouse was using
them as an ur-memory device. |
|
|
Imagine a plastic pipe with contacts at various
intervals on the inner top surface. At the end of the
pipe there was a loud-speaker. |
|
|
By modulation of the sound waves, the top of the
wave would touch the contact (call is a one) and a
wave that did not touch a contact (call it a zero). |
|
|
Feel free to have a go at Neal Stephenson if he was
just bullshitting. |
|
|
YeahI still think you misunderstand what a standing wave
is. See [link] |
|
|
Yes, I finally do realise that a standing wave actually
goes up and down. |
|
|
So why isn't it called a "going up and down wave in the
same place" I know it doesn't exactly trip off the
tongue... |
|
|
Ok, minor edit, the title is "A frozen standing wave of
Mercury chest fridge". |
|
|
Forget the 'wave' just create the mercury container to hold whatever shape you want it to maintain. |

That's why I must only use my powers for good. <stands and waves mercurially> |

|
I was going for an other herm- pun but I could only
find Hermaphroditus, the son of Hermes and
Aphrodite. It's all Greek to me. |
