Inert Gas Kitchen Tap

Argon/CO2 mix from a flexible hose, located somewhere between the stove and the fridge.

It's well known that vacuum sealing your food lets it last longer, but a quick blast of inert gas into a tupperware, sandwich bag or milk bottle achieves the same thing without the impracticality (and crumpling indignity) of evacuation.

Also useful for putting out fires, and if the need arises, welding.

       What if instead of relying on a supply of inert gas, it was like a selective vacuum and removed only the ert gas leaving behind the inert gas.

       Nitrogen is going to be your best bet for this. A home nitrogen production plant and/or large gas cylinders are both feasible.

       why the co2 ?

       //why the co2 ?//   

       In case you want to weld with it of course. Who hasn't been caught short while swinging a TIG around the kitchen, all out of Argoshield?

       Should have a panel with dials to control the amount of each of a selection of useful gases.

       Quite - what if you want nitrous oxide in your packed lunch, rather than nitrogen?

       I wonder if lack of oxygen would just encourage anaerobes?

       //I wonder if lack of oxygen would just encourage anaerobes?//   

       I'm not certain of that, but I do know that modified atmosphere packaging is a thing, especially for meats. If you buy meats in a disposable tray with a plastic top that is pillowed up, that's because it's been injected with nitrogen to give it a longer shelf life.   

       ETA: Wikipedia tells me it may also include carbon monoxide because it helps maintain the red color of the meat, and CO2 is used for vegetables because it slows the ripening process. Also you don't actually want to go to zero 02 for exactly this reason (anaerobes), but a lower than atmospheric level is a good thing.

       What about mustard gas — for the times when your packed lunch lacked punch.

       Did you take that line from an ad for jalapeño cheese sticks?   

       Oh my! HB has betildad my n!

       + You could make this system pretty easily using a commercially available oxygen concentrator, which is also a nitrogen concentrator. Normally, these devices just vent the nitrogen back into the ambient air, but it wouldn't be hard to modify one to store the high-nitrogen, low-oxygen air in a low pressure (2-5 Atmospheres) reservoir.   

       Deoxygenated air is good for storing not just food, but anything you don't want to oxidize/rust - old CDs, jewelry, razor blades, etc.

       I often wish I could do a little welding whilst making some Chicken Marsala. Sounds a wee bit dangerous, but we have firemen standing by just for this sort of thing. +

       [blissmiss] "Chicken Marsala" sounds delicious. I'm imagining a very alcoholic chicken curry.

       I have wondered whether a high nitrogen / low oxygen atmosphere would help with long term storage of staples like rice etc if one wanted to store emergency provisions in case of zombie apocalypses.
AusCan531, Apr 16 2015
  

       Dry white rice and beans last pretty much forever anyway, so I'm not certain what you'd gain.
MechE, Apr 16 2015
  

       //store emergency provisions //   

       Yep, pretty standard fare with preppers and the like, typically varying sizes of plastic drum purged with nitrogen is the go, for things like wheat and rice and the like. Also very suitable for long term storage of seeds, or at least some seeds.
Custardguts, Apr 16 2015
  

       Or just exhale into the bag.   

       Most of us give off plenty of excess CO2. The moisture might be a problem though.
