Hello Collin, and thanks for your review of the Otto. I'd like to know more about how the Otto differs from the Atomic, which was its obvious inspiration. From what I understand from Craig Hiron, the Otto developer, the "kettle" is actually separate from the body of the machine, unlike the Atomic in which it is an integral part. (The bottom of the Otto is supposedly open, exposing the separate "kettle" unit). Can you explain the reasoning for this design and discuss whether or not it offers any sort of advantage over the classic Atomic design?

I am not sure what you mean by "kettle".

I have asked Craig Hiron to join us in the forum in the next 24 hours.

By "kettle" I mean what might also be known as "boiler" or "reservoir" --- the vessel which holds the water and in which it is boiled. Craig refers to it as a boiler:
Per Craig:
"The main body has a completely open base. The boiler is an independent sealed pressure vessel (a short cylender with it's own lid, again, independent of the main body).
During assembly, the boiler (attached to two stainless steel braided hoses which carry the water and steam separately to the steam wand and head) is inserted into the base. These hoses are then clamped to their relevant components inside the main body."

Also, a separate issue, I wonder how the design contributes to Otto's being able to produce a 3-bar pressure as mentioned in your review?

I will leave that explanation to Craig -

Note: when the brewed coffee is coming out of the PF and group, it "streams" in in 2 per second long drips - syrup like... It is not an continuous stream like what you would see out of a pump driven espresso machine.

And, you get 2 fluid ounces of espresso coffee.

I only wondered about the 8 ounce jug that OTTO ships with - because you do not get a "cup" of espresso out of it.

Thank you, Colin. While we wait for Craig to weigh in regarding the advantage of separate boiler rather than integral (as in the classic Atomic) as well as how the Otto attains 3 bar pressure, could you do us a favor and turn your Otto upside down and take a picture of the bottom so we can get an idea of what the "open" bottom described by Craig looks like?
BTW, do you happen to know if the separate boiler is made of stainless steel, as is the body? Thanks again.

Hey Alan, thanks for getting the information. I have always wondered how different the boiler could be from the Atomic. I just assumed that it was similar to the Atomic. I guess I was wrong.

The boiler concept is definitely great, but it must take a very long time to bring the water to a boil. It might even take longer than the Atomic!! If the vessels are seperate then I am guessing it can't be too thermodynamically efficient. Then again, what is??

I really need to get a hold of the OTTO to compare it with my Atomic. Hopefully soon! Well, when I can afford it. But I am sure it's worth every penny. I just can't imagine how much time Craig must have spent looking into the thermodynamics and fluid dynamics of this machine.

They are actually offering a discounted price for the friends of OTTO, which will only last till the 6th of Sept:(
