If you add salt to the ice it'll chill even faster.

Didn't mythbusters do an episode on this once? Fastest way to cool a beer, or something like that? They concluded that the fastest was to use a CO2 fire extinguisher.

In rural areas in Peru I've seen natives dunking closed beer bottles on water, then add nitrogen based fertilizer to get them chilled really fast! (A strong endotermic reacion happens)

Dry ice will, ironically, make your soda go completely flat as it constantly agitates the drink as it boils/sublimes away.

Cubes of frozen alcohol might work. Maybe with a little frozen C02 mixed in for certain drinks.

I love it! Now I just have to figure out how to generate a temperature cold enough to do it.

I think she meant reverse microwave oven. As in, rather than heating fast, it cools fast.

That is like calling ice a reverse fire. If the technology doesn't have anything to do with microwaves, I don't see how the "reverse microwave" adds anything but confusion. It's not as though "chills beer in 45 seconds" is so vague as to require a strained microwave analogy.

I loved this comment, why is it being downvoted?

There used to be a chilling device as a party store near my house. There was a tub of super-chilled green or blue liquid that was in a whirlpool of sorts, and you could dunk your just-purchased drink in there for 1 minute and it would be cold when you took it out. But doesn't beer benefit from always staying cold?

Not really. Some people call it "skunking" when one keeps changing the temperature of bottled beer, but it's harmless. Real skunking is exposure to light.

I voted you up for truth. But... don't discount the profound disappointment that a headline like that generates in those of us who do know how a microwave works. We were teased with the idea of learning something we thought would alter our understanding of the universe -- some sort of microwave version of the peltier effect[1] -- only to find out it was something as pedestrian as poetic license.

Those who know physics would hopefully know that a cooling microwave would be a blatant violation of the second law of thermodynamics.

I'm skeptical about the energy claims. How much of a difference is the continuous cooling of a can of beverage going to cost when you still have to keep the refrigerator running anyway? Plus energy grids prefer a gradual and predictable energy draw than a sudden spike. Otherwise we end up with scenarios like this: https://www.youtube.com/watch?v=slDAvewWfrA

I think the idea is that there is no more need to keep all the beverages cooled the whole time. The bottles can be stored at room temperature and the customers only cool those bottles down they buying.

So the energy savings are not in the individual cooling process.

Oddly enough, your response is basically the same sort of overly-narrow literalism that gojomo was complaining about, just from the other direction.

No it wouldn't - as long as the device, target and environment heat up as a whole. For ex, laser cooling where a laser reflects off a surface with more energy than it started with.

No, it's not.

"reverse microwave" is correct in a sense, because as gojomo pointed out, the author meant it as a way to convey the concept of "rapid-heating appliance".

"You can't do x because of thermodynamics" actually was incorrect, and didn't take into account multiple specific instances which show that closed systems can create such results.

Since we are going off on a tangent, a cool camping hack when you don't have ice is to stuff a beer in a tube sock, dunk it in water, and hang/tie it to a tree branch in the shade. If there is even a touch of wind it will be nice and cold in 10 minutes.

I wonder if you wound up the sock and let it spin if you'd get something virtually equivalent to this machine.

I think you need to experiment.
