I already did that, and when I flipped the switch I was damn near eaten by a Grue. Never again.
Isn’t cooling the very nature of entropy? The gradual dissipation of heat to reach equilibrium with the surrounding temperature? Not that it matters, since the idea here is to beat entropy about the head long enough to reduce temperatures rapidly.
Darkbulb? Anti-microwave? This sounds like it’s right up Prof. Farnsworth’s alley!
Re the Blast Chiller:
“Model FXBC10 has 10 kg capacity and can blast chill product from 70ºC to 3ºC within 90 min to maintain food quality and ensure HACCP food safety law compliance. Chiller enables left-over food from hot servery counter to be quickly and safely chilled for later use with complete confidence in its quality and safety. Suited for restaurateurs, hoteliers, and publicans, it also aids in advance food preparation by chilling larger batches for later use.”
Emphasis added.
90 minutes? Who wants to wait that long for an ice cold beer? When I invent my anti-microwave, it’ll take a 2-4 from summer’s-afternoon-in-the-trunk temperature to spine-tingling frosty in 90 seconds.
I bet that’s worth a Nobel…
well, [URL=http://www.cybercandy.co.uk/aaasmt/index.php/url_indprod?xlc=945]this guy[/then] is claiming 60 seconds.
isn’t there also some do-dad to instantly chill wine?
The quickest way to chill a beer is to put it in a bowl of ice, water, and rock salt, and stir the water around it really fast. You’ll have ice cold beer in seconds.
Well yes, if you start with something hotter than its surroundings. But if you have a nice cold bottle of beer, entropy will drag it towards room temperature, and you’re not going to be able to reverse that process without creating some more entropy somewhere else (like, say, out the back of your refrigerator).
Notice how that item had become discontinued, despite universally positive reviews?
I timed the rotation of my microwave turntable this evening and it does indeed take 12 seconds per full rotation here with 50Hz AC mains. I would not have thought it so slow if I hadn’t actually timed it.
I saw a rapid-chiller in a liquor store once. It was a swirling bath of (I assume salty) water that was somewhere south of “damned cold”.
Buy your wine, stick the bottle in for a short bit, and walk away with cold wine.
Yes, there is a place near me that has one of these. I’ve never tried it (I rarely buy wine that I need chilled right away. Or ever, for that matter).
Dude, when I get impressed with myself for knowing more than my HS students, I can always count on a QED post to give me an intellectual wedgie in the technical/science department. I know that everyone who knows more than you looks like a freakin’ genius, but this happens over, and over, and over…
I’m going to have to play with this. It’s one of my really, really minor pet peeves that my coffee cup always comes out with the handle facing backwards, but it should be a 50/50 shot!
My last microwave pulled a rather horrifying trick on me: it started emitting microwave radition when the door was open :eek: :eek: :eek:
I knew if I just threw it away as it was, someone would use it (we were living in Egypt, where everything is recycled by trashpickers) and I didn’t want to be responsible for some child’s cells getting scrambled because they were standing in front of radiating microwaves with no shield. So I took that sucker apart with a screwdriver and damaged the insides beyond repair.
It was rather satisfying, actually.
Are you sure about that? More likely, only the light and fan were running. All ovens have not one, but three, interlock switches to prevent the actual magnetron from energizing (only one of these interlocks the light and fan, however). The last line of defense here is the third interlock which, when all else has failed, will create a dead short to ground thus blowing the fuse. It would take a spectacularly unlikely failure of all three interlocks switches at the same time to allow an oven to radiate with the door open or even slightly ajar.
(that smiley used to be a tongue sticking out) Not that I hope you choke on your next re-heated pizza or anything.
Wouldn’t that be a macro-wave?
The darkbulb does exist. It’s called a black hole.
Indeed, that thought did occur to me and maybe that’s all it was. But it was just way too weird for me - you’d open the door, all would be normal, and all the sudden for no particular reason it would turn on by itselt. I didn’t want to mess with it, since even if I had proven to my satisfaction that it was only the light and fan, it would have been a very scary microwave.
Tricky to package and sell alongside the lightbulbs though.
That’s the quickest practical way to chill it, which MythBusters lists as taking 5 minutes to chill a beer to “satisfactory temperature”. A fire extinguisher only takes 3 minutes.
