   Help me design a fast beer cooler
  So I am 21, but my mother, whos basement I live in and practice the nerdly arts, does not approve of alcohol and I argue with her enough as it is.  Therefore a refridgerator is not an option.  So I need to build a concealable device (like 1ft by 2ft max size).  My current solution involves putting ice packs in cold water and using that to chill, but those take time to refreeze.  And a second set of packs is way too practical, so obviously I have to make some wierd contraption.Ideally it needs to use electricity as a source, either to run a pump or some other method, like using current to create a hot and cold sided plate (do not remember the name).Ideally I would like to be able to cool 12 ounces of room temp beer to 47f in 5 minutes, however it does not need to cool it in the can/bottle, as long as all the beer is recoverable.The largest challenge is price, which must be low.  Also, no dangerous chemicals/exhaust.  Any ideas?   
  minifridge, it'll only hold maybe 4 cans (well mine did but it was only about 10-15 pounds sterling, you can get bigger ones) but as soon as you take one out you put another in and it should be ok by the time you reach it. just plugs into the mains.   ;Quote:Original post by WitchcravenAny ideas?Four steps:1) Get a job2) Get a place with fridge3) Pay electric bill (see step 1)4) Cool "adult" beverages in fridgeEither that or talk in a British accent and start throwing forks.;  MythusBusters did an episode regarding cooling beer down really quickly. I just don't think refilling fire extinguishers is neither practical or cheap.Why isn't a refridgerator an option? Sure it is their house and you have to follow their rules (or move out) but can't you just say it is for cooling food? You can get pretty small fridges for nice and cheap and they certainly will come out to be the most cheap and practical way of cooling down things, especially beer. I mean, they are afterall designed to do just that.But you want to build something that doesn't cost very much, doesn't use any dangerous chemicals, doesn't have any exhaust and to top it off - chill beer from 92F to 47F in 5 minutes??? If you were to ever make such a thing - you'd be a rich man.   ;here and here ;)   ;Quote:Original post by happybarahere and here ;)Brilliant.  Thanks.beer from 92F to 47F in 5 minutes??? If you were to ever make such a thing - you'd be a rich man.Room temperature is 70 here.Quote:Four steps:1) Get a job2) Get a place with fridge3) Pay electric bill (see step 1)4) Cool "adult" beverages in fridgeI plan on that.  But I am not sure how long that will take.  If I continue college, a while.  Working full time and going to school full time is possible, it is not appealing.  If possible I prefer to operate on low stress levels.;I just had another brilliant idea!;  Don't know if Liquid Nitrogen qualifies as a "dangerous chemical", but if it doesn't I'd say it would proberly be a good soloution.Bassicly use the same setup as you do now, but instead of putting ice in the water pour a dose of LN down in the water instead. It would give some cold water with ice in it realy fast. The only problem as I see it is that it evaporates pretty quickly and you'd either have to buy a lot, or go buy it every time you want a cold beer.A quick search for pricelist puts it at 2$ a liter. Don't know whether there is a place near you that will sell it to you (at that price). Some places has been known to give it away for free for educational purposes, (it's apparently insanely cheap to extract) but I don't know if freezing beer qualifies. [smile]   ; Buy a super soaker. Put all your beer into super soaker. Pump like there is no tormorrow. The pressure in the air resivior has to reach near critical (eg.. the container being on the verge of exploding). At this pressure, it will have significant thermal energy(You'll also be surprised by how much beer you can fit at that pressure). Let it cool to standard ambient temperature (eg.. give it 10 minutes to cool).(note, image below refers to a slightly different model, but the concept is the same) Hide gun under bed until your ready to use. When your ready, simply fire it off into a cup, or directly into a mouth (Why do I shrug?). The rapid decompression will cool the beer very very quickly.;  HAHAHAHA
