If that were true, every $200 espresso machine would be temp stable and a dream to use.

Of course I'm not saying that you can make a good espresso machine for 200$. There, problem is a small boiler and pump delivering cold water into it during brewing etc. But this is not an espresso machine and you can get quite good coffee for much less than 200$, just you can't get a good espresso for that money

Again, I'm asking about working principle of this machine

You're still delivering cold water to a pressure device. You were saying controlling the numerous variables of espresso is a matter of some cheap parts, and I just don't think that's true. No one has done it yet, in any machine at any price. He'll, adding a pid alone to silvia is a $120 proposition, off the shelf, and that's just boiler temp.

I think this could be pretty cool, but at only $500, it all just seems too good to be true right now. I wonder what some people would be willing to pay for a well built machine that could pull espresso like a Slayer, and mimic immersion/pourover brews at the same time. One thing I don't see in any of the pictures is a steam wand or a second spout, and I can't imagine that they're planning on ignoring the milk drinkers out there...

I bet the "steaming" feature will be a superauto style bubble bath with a tube or container to draw milk from. I don't see them adding a traditional steam wand on something like this.

Certainly an interesting concept but i dont want the difficulty of brewing/pulling high quality beverages to be taken away.. i dont want coffee to be a dull thing.. it should be challenging

Maybe they could at least try and replicate the Breville Oracle's in between approach. It seems to work pretty well.

That would be very nice. I do sometimes miss the auto steaming my Oracle had. Flip lever, walk away to do something else, and it cranks out perfect foam. Given the price point, I also wouldn't be surprised to see them leave it out completely and either provide or recommend a stand-alone milk frother.

I emailed them, and you are correct: there will be an optional frothing accessory thingy.

I just wanted to say thingy. :p

Looks very cool! And BIG-- very big....
Indeed, centrifugal coffee has been around for a while and Nespresso uses centrifugal extraction in their Vertuoline coffee makers....
The neat thing I see here, aside from having control of speed, etc., is the control of the depth and breadth of the "puck" for hot water to percolate through. Infusion at low RPMs and then throttle away during the extraction--like a Slayer, or Strega????? No more tamping? Different sized drums (proxy for baskets) would offer varied puck depths and extraction forces/profiles.

Thin layered pucks may offer new extraction possibilities--Ringworld meets espresso?

The floor of the centrifuge already moves, for puck ejection purposes. but it's not the depth of the centrifuge that will have the effect, because the grounds will be compacted as it spinn, with the walls of the vcentrifuge becoming the floor as it rotates. Dose size will affect depth automatically.
