Microwave-equivalent cooling device
Anytime you need to warm some cold soup or anything, you just use the microwave. TA DA, cold becomes hot in seconds to minutes.
What we need is an equivalent cooling device that can chill or freeze an item of food or drink in seconds to minutes. The fridge/freezer can do this in minutes to hours, but sometimes the game is about to start and your beer is still room temperature! Unacceptable...I mean you can put a man on the moon but you can't chill your damned beer in a timely fashion?!
Microwaves excite water molecules in whatever is in there, making them vibrate faster and making the item hotter. A reverse effect probably needs a different mode of acting, maybe not with microwaves. Wait, what if the wave is out of phase?!?

One of my classmates at Georgia Tech made a device for his mechanical engineering capstone design project that would chill a beer or soda in a matter of seconds by spinning the can and spraying it with a compressed gas (CO2 or N2). As the gas expands it cools the can. The difficult part of the design is stopping the gas spray before the can freezes.
you can very quickly cool beers with this little gizmo

additionally, if you want to cool beers in 5-6 minutes

also, heat is not the same thing as cold. cold is the absence of heat. it is way easier to add energy (heat) to a system, than to remove energy from a system, because moving energy itself requires energy, i.e., all energy transfers create heat. the way an air conditioner or refrigerator works is not by generating cold, but by moving heat out of the fridge to a vent.
in other words, it is always going to be harder to cool something than heat something.
The salt trick is nice but not very practical, unless you want to buy pounds of salt to use this regularly.
Clearly it is more difficult to do, which is why we don't see it already. But there clearly must exist a principle we are unaware of to easily "steal heat" from something, without requiring any "invasive" mixing and stirring. We need a practical way to do this as easily as microwave heating is.
when you chill decent beer that fast, you're bound to ruin the flavor. any beer that has been allowed to get very warm, or beer that has been chilled and then allowed to reattain room temperature, is going to taste like shit if you chill it again. that's not so much physics as it is food chemistry. taking proper care of your beer in the first place is the right course of action.
They have machines in the supermarkets here that will chill a bottle of wine in 5 minutes, for free.
as far as the "microwave" part of this goes, adding any sort of wave to a system-from radio to ultraviolet-will only add energy to the system, so that doesn't work. the GT design works because a) it spins a can as it sprays it with gas, so that maximum surface area is cooled, and b) spraying it with a compressed gas will allow all of the heat from the can to diffuse into the cold air, so that maximum heat loss is achieved. The key is that you only cool something by losing heat, not by adding "coolness" or whatthefuckever.
A microwave works by jostling the water molecules inside of what you are cooking, generating heat inside the food. I think it would be great to have a cooling device, but it wouldn't work at all in the same way and definitely would be extremely less cost and energy effective to have in the home. Like a previous poster said, it is a lot harder to cool something than to heat something, because heat is easy to achieve with motion, which is what the microwave does.
My friends and I used to think about this invention when we were baked back in high school. We called it The Cold-o-wave.
i'd buy one in a heartbeat....f*ckin hate waitin for my beer to get cold and other drinks
Ever seen the movie Haggard?
You just gotta use freon!

hahahaha i thought the exact same thing!!
Brandon Dicamillo beat you too it losers
thats what i thought too dude. the reverse microwave. fuckin dico... :D
Finally, someone who believes in the microcooler.
if yo take a bowl of ice water and add salt it will lower the freezing point making the water much cooler and will cool a beer in about 2 min, depending on the size of the bowl and amount of the ice
try this with a bathtub if your having a party
fastest way steal a fire extinguisher 32 pack in a cooler and unload the whole fire extinguisher upon them
Been around for a long fuckin time: http://en.wikipedia.org/wiki/Flash_freezing
this was an idea on bam margeras movie. i forgot what the movie was called. but i think dica named it the backwards microwave.
I posted it above. The movie is called Haggard. =P

dude ive been saying this for years !
at least someone in the world gets me !
i have had this thought since i was like 10. and it makes me so happy that someone else agrees with me. everyone i say that to says "oh you can just put it in the freezer'. nay i say sir douche bag.i want my beer cold, and i want it cold it about a minute. if i can have hot pockets boiling magma hot in less than 2 minutes, a drink should be able to get perfectly cold in the same amount of time. wahPAH.
dooooooooooooood totally needed this last night. I wanted my long-neck root beer with dinner but the freezer took 10 mins. ended up getting it after. This is needed.
