The time from ordering to delivery is about 5 minutes. But they must have addressed the rate problem. This is from one of the web sites covering thi s.
Vardakostas, a 27-year-old physics graduate from UC Santa Barbara, says the Burgeon can crank out a burger every 16 seconds. It grinds the meat, stamp s out the patty, sends it along a conveyor-belt grill, toasts the buns, squ irts on the condiments, slices and drops in pickles and tomatoes and lettuc e, then pops the finished burger into a bag, all in under five minutes.
And, says Vardakostas, "we're trying to bring it down to a completed burger every 10 seconds."

A 5 minutes cycle time was the target value. That included approximately 30 seconds to punch buttons at the front end, and about
15 seconds to remove the hamburger and inspect it, before moving out of the way. The 5 minute time was set by testing using a simulated vending machine. People would start pounding on the machine after about 2 minutes, so the front was decorated with status lights.Assembling the sandwich is fairly easy. Cooking the burger is not so easy. I found your quote near the bottom of: Note that the article doesn't say anything about actually cooking the hamburger, just assembling it. If he's using pre-cooked meat, my 40 year old experience says that it's going to taste awful. I don't think he can go from refrigerated to fully cooked in 5 minutes. Besides, he would need either a "browning dish", hot wire toaster, or a natural gas flame thrower to scorch the outside of the patty in order to make it look like it was cooked. He does mention "toasts the bun" but nothing on the actual hamburger cooking time.
Also, I didn't see any refrigeration. I don't recall the exact number, but meat can only sit at room temperature and unrefrigerated for something like a maximum of 30 minutes. Never leave ground beef or any perishable food out at room
As I vaguely recall, since the inside of the machine operated at elevated temperatures, we were limited to about 10-15 minutes at room temperature, even with internal refrigeration.
Partial cooking doesn't work: Is it safe to cook ground beef part way, then store it to use later? No. Partial cooking of food won't kill pathogens, but instead allows them to multiply to the point that they can't be killed by subsequent cooking.
Incidentally, if you need some entertainment value at your next barbeque, try fast cooking a hamburger with something really hot, like a propane or oxyacetylene[1] torch or other open flame. When I've tried it, all the water was instantly vaporized, the meat carbonized, and sometimes the grease caught fire.
Offhand, I think I could probably do better with a pick and place robotic arm to do the cooking on a grill, and the assembly on a conventional counter. At least the grill would be parallel processing instead of serially cooking one burger at a time.
[1] In my college days, I worked on building Rose Floats for the skool. I did mostly electrical: There were no nearby cooking facilities, so I tried to cook a hamburger on a steel pan with an oxyacetylene torch. Instead, I burned a hole in the bottom of the pan.

Assumption, the mother of all screwups. Since the quote came from the local Mercury News, which has a history of bad science and misquotes, I not take the article at face value. I guess it is a fair assumption that the hamburger was cooked at some point before or during the process.
Have you ever owned and operated a convection oven? Basically, it's a hot air cooker. If you have an SMT desoldering station, you can try using that to reheat your lunch as see what happens. There are many good things about convection ovens (better efficiency, even temp distribution, faster cooking, no carbonization), but keeping them clean and dealing with the evaporated moisture balance the benefits quite nicely. Even worse, as the volatiles condense on the inner surface of the convection oven, air flow become turbulent and cooking time increases.
During the development, someone devices with what I would call cooking with explosives. The hamburger was first injected with water using an array of syringes. The patty was then cooked with a very high power microwave (3 to 5 KW as I vaguely recall) in a sealed chamber. It wasn't the microwaves that did the cooking. It was the boiling water that did the cooking, from the inside. I recall a few impressive steam explosions. This was followed by natural gas searing to seal in the grease (the flavor is in the fat). The resultant patty was very loose and tender, tasted great, and could be cooked quite rapidly. Too bad the process was dangerous and somewhat messy.
Won't work. Adding a full service butcher shop to the local McDonald's is probably a bad idea. The meat arrives pre-ground and refrigerated from the supplier. Once it's thawed, it has to be used almost immediately, or tossed. Cooling it again isn't allowed. Even with continuous cooling, the allowed storage time is something like 2 or 3 days.
Hmmm, none of the photos show how the ground beef is stored or dispensed. My latest guess(tm) is that they use a conventional flame boiler, with a conveyor belt, to cook the hamburgers, and then use their machine to just apply the condiments, buns, and packaging.
The ladyfriend has one. Works nicely and she's a far better cook than me. However, after dinner, I usually get to spend some quality time getting to know the convection oven by removing the encrusted food residue from every surface with sodium hydroxide (Easy-Off). My microwave oven just wipes clean, but the convection oven requires scrubbing and noxious chemicals.
Note that high end production flame broilers and ovens usually include an air convention system mostly to improve efficiency.
Sure. The machine could easily be scaled into something the size of the typical fast food kitchen. For example, Nieco makes a conveyer frame broiler system. Burger King tour: (start at 1:50 for the flame broiler).
I guess if the fast food restaurant only sells hamburgers, such a machine might be useful. However, it does nothing for all the other junk on the menu. I still think a pick and place robot would make more sense because of the versatility. As usual, Japan is ahead of the curve: (6 min) Worth watching just for the future shock value.

A few weeks ago, one of my friends mistyped my email address when sending me a request for a health status report. The email went to another Jeff, who had recently died. His widow replied indicating that Jeff is dead. To maximize the damage, my friend sent announcements out mutual friends asking them to pray for my soul. Of course, nobody bothered to verify anything by phone or email. Incidentally, this is the 3rd time this has happened in 13 years. I eventually found out what was happening and am still trying to deal with the effects and perform damage control.
Then, this week arrives with this pronouncement: "Lieberman is gone, group is DEAD, no reason to post here" Sigh...
Thanks. I've never looked into life extension and know nothing about it. It will take me a while to read the literature. I should point out that it fails my medical advice sanity test, which is to ignore any advice from people or organizations that have an agenda or product to promote or sell.
My advice is to choose your parents wisely. The problem is that both sides of my family has a history of cardiac related problems. Various family members have tried fighting heredity through diet, exercise, and lifestyle changes, with poor results. At about 60, everyone ends up with a stroke, heart attack, or coronary bypass. I was a bit earlier than most.
What I do mostly is ignore the doctors, avoid fashionable regimes, do my own research, monitor progress, and make my own mistakes. My cardiologist provides sanity checks and the necessary prescriptions. I could probably do more or better, but I'm not interested in living forever. 13 years is considered quite good for a triple bypass, so I must be doing something right. So far the only mistake I've made were taking satins for 9 years. I recently detailed that in alt.internet.wireless:
Nicely done and I hope it works for you.

any significance.
They could, but there's quite a lot of evidence that points the other way, of which you are clearly unaware, and blithely intent on ignoring.
Piketty makes the valid point that the Gini-index is a single valued number , and doesn't say anything about the way inequality is distributed. In prac tice, the shape of the top end of the income and wealth distributions is of considerable significance, because it's the governing elite who get to mak e most of the important choices.
The Gini index still does capture a real difference between US and German s ociety - the fat cats at the top end of the income distribution are fatter in the US, and more powerful in adjusting the rules that let them get fatte r yet, at everybody else's expense.
If you choose to be unaware of this, your grasp of reality is defective.

Proper convection ovens offer a cleaning cycle. When I last looked - which is a couple of decades ago - US convection ovens just heated it's internals to 500C, and the condensed volatiles just burnt off.
The European equivalents had "catalytic surfaces" which oxidised the condensed fats and greases at lower (but still pretty high) temperatures.
Googling "self-cleaning oven" got me this
which suggests that the "catalytic surfaces" have gotten better since I last looked.

That's much the same as the US flavor of self-cleaning ovens. The basic idea is to oxidize the grease and tar that's holding the mess together. Anything that promotes oxidation I guess is considered a catalyst. What's left is easily cleaned up dust. Natural cleaning?
Thanks, I should take a 2nd look at what's available. However, there's a potential problem. I don't think that burning off the grease with high heat is going to scale to fast-food restaurant size conveyerized flame broilers usually used to cook hamburgers. Heating a huge oven like those in the photos is just not going to work. I'll try to ask how they clean it at the local fast food dispensary, but I'm afraid my Spanish might not be good enough.
Incidentally, I was once wondering why I couldn't just heat the barbeque grill with a propane torch instead of scraping off the crud after a barbeque. Well, it worked, but it also peeled off the chrome. What happened was that the steel under the chrome expanded with the heat, causing the chrome to fall off in flakes. It probably would have worked with an all stainless steel grill, but I don't have one of those.
It also doesn't work with the iron hibachi grill, where the grease gets into the pores in the iron. The grill looks clean, but the next time I try to cook something, it has the taste of whatever I previously incinerated on the grill. That's one reason why they recommend NOT cleaning an iron grill and "curing" or "seasoning" it instead.
Thanks. It's all part of my checkered past. I wish I could claim that I had something to do with the design or the electronics. I didn't. My assigned task was to clean up the human factors and process flow mess created by the design team. Everyone was so concerned with getting it working, that nobody was paying attention to whether it was actually useable. For example, there wasn't room for a coin collector that would accept paper money. The undercarriage collapsed as more modules were added. Defrosting the fridge was almost impossible because the ice froze the module release mechanism. Modular construction was great, but there were no carts to handle the individual modules when removed. The viewing angle of the status lights were too narrow to be seen by anyone standing in line to either side. With all the cutouts and lights in the front of the vending machine, the painting of a giant hamburger looked like an alien crab-like visitor on a flying saucer. Various operations made various noises, all of them undesirable. Opening the front door to receive the hamburger would result in a blast of steam in the face and a soggy burger if one waiting too long, and if the clean cycle had already started. Opening the back door to reload the various food tubes triggered an interlock which caused the timing system to reset. That meant that any burger in process had to be removed from the mechanism before proceeding. The delivery door was too high to be reached by children. As I vaguely recall, I found about 150 such deficiencies. The problem was not fixing them, but rather convincing the various members of the team that they should fix them. I managed to get a few things fixed, but there was no way I could demand so many major changes. It was rather fortunate that the project was terminated prematurely or I would surely have been defenestrated by the other members of the team.
One aspect of the project was rather unusual. There were security leaks all over the project. Everyone knew that Compu-burger was coming. It was decided that it would be helpful if we exaggerated the capabilities of the machine to the known sources of the leaks, in an effort to render the previously leaked information unreliable. I was judged as having the most virulent imagination and soon found myself producing reports, stories, and sketches describing features normally found only in science fiction literature. As far as I could tell, it mostly worked.

Really? Adduce the evidence, or at least point to it.

The Gini numbers are just numbers. The Wikipedia table lists a lot of them and I quote it as a convenient source. I was interested in the Germany/Scan dinavia versus US numbers, which was what I was talking about. The fact tha t the table lists a bunch of less reliable numbers for countries that don't collect reliable statistics is unfortunate, but doesn't make the numbers f rom the reliable countries any less reliable.
The fact that the Afghan numbers aren't reliable isn't any kind of argument for ignoring the German, Scandinavian and US numbers.
es were vastly different.
Me too. Otherwise I would have said something to that effect.
an society - the fat cats at the top end of the income distribution are fatter in the US, and more powerful in adjusting the rules that let them get fatt er yet, at everybody else's expense.
The US collects about 30% of the national income in taxes, the UK about 40% France about 50% and Sweden about 54%. The US government doesn't spend eno ugh on it's health system, education or welfare, the UK at least spends eno ugh on the National Health service, France spends more on a better universa l health system, adequate welfare and education, and Sweden spends even mor e on all three.
The low US tax take favours the rich, and disadvantages everybody else. Sin ce Regan came to power, the bulk of US economic growth has flowed to the to p 10% of the income distribution, and the bottom 50% has seen their real in come stagnate.
Inter-generational social mobility is higher in Scandinvia than pretty much everywhere else, while it's lower in the US than in pretty much any other advanced industrial country. In the US the rich are getting richer at every body else's expense, and it's not a situation that's likely to remain uncor rected.
In general the rich do get richer at everybody else's expense. Piketty ment ions the interesting case of university endowment funds, where the richest universities can afford to spend a lot more on buying the best financial ad vice.
Harvard, Yale and Princeton ($30 billion, $20 billion and $15 billion) achi eve a return on capital of about 10%. The average return is about 8.2% and for institutions with less than $100 million the rate drops to 6.2%.
In real life, having a couple of million tucked away means that you can buy up a failing competitor for ten cents on the dollar, even if their problem s were merely temporary
a couple of cents per share. On the other hand , the government run lotteri es are a real ripoff taking money from those that can least afford it.
Lotteries are certainly a rip-off. Sadly, the people that can least afford to gamble are particularly devoted to gambling, and used to spend their mon ey on "the numbers" when that was a service offered by the Mafia.
If people are going to gamble anyway, it makes sense for the government to offer them lotteries. Not all the government's margin on the process will e nd up spent on the electorate, but Pennsylvania's 98% isn't bad.
