No.

Well, maybe. If it made 5,000 cups of coffee a day, enough for everyone serving on an aircraft carrier, then sure.

But do the math-- how many cups of coffee a day can this thing make? How many cups can it make over it's entire span of uesefulness?

Let's say you want to recoup the cost in two years. That's $460/month. Say you're the LL Bean of coffee houses and you're open every day. That's $15/day. Well, at that rate, say you're open from 7 am til midnight. That's 17 hours a day. Call it a buck an hour. If you've got people lined up to pay $3.50 for a cuppa joe, you'll make back the dough and have a nice bottom line. At $7 you're minting money and at $10 per cup you should be jailed for price gouging and excessive chutzpah. But in purely economic terms, is it worth it? Well, you could amortize it as outlined, but could you make as much dough with a smaller capital outlay? I bet the answer is yes, which then makes it a slightly different question, and the answer might swing back in the "no" direction.

But if the Q is "Could a Coffee Maker Be Worth $11,000 for an average person?" then the answer is yes and no. Of course not, because there are plenty of much cheaper ways to make decent coffee. And yes, because economists assure us that we are maximizing our utility, and by that method of thinking, any gizmo is worth what someone will pay for it.

Also, this coffee maker is not worth $11,000 because it "isn't mass produced." You could put a similar contraption together using less than $500 in off the shelf glassware and electronics.

Sadly, the same could be said for a Tomahawk missile.
