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.-- not_morrison_rm, Feb 03 2019 diagram https://drive.googl...DsOA3JSQag5aeMvFcXn [not_morrison_rm, Feb 07 2019] Standing waves in a wave tank https://www.youtube...watch?v=NpEevfOU4Z8Starts 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.

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.-- Voice, Feb 03 2019 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.-- not_morrison_rm, Feb 03 2019 Are you imagining a standing wave as producing a static slope of mercury, deeper at the cold end?-- notexactly, Feb 04 2019 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.
Link.-- not_morrison_rm, Feb 07 2019 I don't understand why the mercury needs to be in a standing wave, or how the standing wave is maintained-- hippo, Feb 07 2019 //Are you imagining a standing wave as producing a static slope of mercury, deeper at the cold end?//
You'd have to watch it under a strobe light of the right frequency to make it hold still.-- Loris, Feb 07 2019 //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-- hippo, Feb 07 2019 (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.
</End of explanation/s>-- not_morrison_rm, Feb 07 2019 YeahI still think you misunderstand what a standing wave is. See [link]-- notexactly, Feb 07 2019 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".-- not_morrison_rm, Feb 07 2019 Forget the 'wave' just create the mercury container to hold whatever shape you want it to maintain.-- 2 fries shy of a happy meal, Feb 07 2019 [2 fries] ...ruining everything with your simple, practical suggestions!-- hippo, Feb 08 2019 That's why I must only use my powers for good.<stands and waves mercurially>-- 2 fries shy of a happy meal, Feb 08 2019 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.
