You never know where you will be, or what time it will be, when you really need some fresh liquid nitrogen on hand. Ideally, these LN machines would be located everywhere.
UPDATE: as several commenters have mentioned, this machine could be improved by adding other scientifically interesting substances.
For example, liquid oxygen and hydrogen (for budding rocket scientists), argon, mercury (for those unafraid of poisoning), sulphur hexaflouride (for those who want to hide their squeaky voices), and dry ice (to help with sequestration from the admosphere).
UPDATE2: Also, chunks of metallic sodium. (I wonder if they should be dispensed in a protective container... NAH!)

It might be a pretty small amount for a dollar. |
|

[+] While you're at it you might as well dispense Oxygen and Argon too... also refill those little CO2 cartridges and sequester out the rest. (The ad campaign: "Buy our LN2 and stop global warming!") |

How much energy required ? |

[AntiQuark], would you find it inconvenient or embarrasing if we arranged for you to be worshipped as a God ? |

Generations of Mad Scientists have been forced to live their lives without the benefit of this unparalled boon to their calling. May Angels and Cherubim sing you to sleep every night. |

You mean, people don't currently worship me? I am quite disturbed by that revelation. It means that my wife has been right all along. |
|
| |
...and while we're at it would a little sulphur hexaflouride be too much too ask? |
|
| |
And, if you please, add pure sodium for any vending machines near bodies of water. Great sport for the kiddies! [+] |
|
| |
Damn you, [bigsleep]; we'd have gotten away with it too, if it weren't for you pesky kids ... |

There's no easy way to tell you this .. |

The Horror ... The Horror .... |

No, but you can ch... I'll ask the butler to get me
coat. |

The only thing you won't require from this wonderful machine is a bun dispenser as you've got mine. I think part of the attraction is the anonymity of the purchase. None of those awkward questions as to why I want liquid nitrogen or pure sodium when the only true answer is 'just to mess around'. |

[AQ] I took it for granted that you were contemplating simple atmospheric distillation... though in retrospect a diffusion membrane would work just as well, if not better in some respects. |

You mean I'd no longer have to make my own thermite*?
Goodbye home-built electrolytic bath** in the garage, hello
coin-operated convenience! |
|
| |
*strictly used for commercial welding-related processes, I
swear. |
|
| |
**for the production of large amounts of iron oxide. It
smells terrible. |
|
| |
I have something like that in my garage too! But mine makes heavy water*. |
|
| |
*for the purpose of: none of your damn business. |
|
| |
I have a pretty good idea what it's for, but I won't let on.
Just don't mistake it for beer. Very embarrassing, I'm told. |
|

The cup of liquid nitrogen could run my ice-cube ball
vending machine for an hour or two. |
