#2After the last one of these posts talking about cold brew coffee I attempted to replicate the results by just throwing some water and coffee into an ultrasonic jewelry cleaner. Results were not satisfactory. I wonder if extracting the transducer from the jewelry cleaner and attaching it to my Portafilter would work.

#3My dad was stationed on a submarine in the navy and he and a few others used to dump their laundry in the ultra-sonic cleaner normally used to clean engine parts. Said it did a great job....

#4I tend to wake up before my partner, and I can only imagine the look on her face when the ritualistic grinder noise gets joined by a noisy brewer.
In all seriousness, people tend to have a routine around coffee, but I think the Aeropress showed that people will change if the result is meaningfully better.

#5I see the value for American-style "espresso-flavored" drinks, or similar bottled/packaged products.
But, yuck, who on earth wants to drink actual espresso at room temperature?

#6At a 3 minute shot, I’d rather use the same time to do a pour over

It’s ultrasound so presumably it will be difficult to hear

It'd be a learning experience to find the right settings.
Coffee usually goes in two directions. Under-extracted (sour) or over-extracted (bitter). Things that will affect the extraction are temperature (hotter usually means more extraction), time (longer = more), grind size (more surface area in smaller grinds = more), pressure (higher = more) etc. Roast levels also matter.

#9"Most of us think of espresso as a hot, high-pressure ritual." - No, most of us dont care how the sausage is made, and just want the end product. Sure theres lots of individual coffee enthusiasts who cares, but in % terms thats not "most of us", most of us do not care, and nobody in my 40 years of life has ever complained about coffee energy usage.
Extract with sound waves is an interesting idea, but dont romanticize demand that doesnt exist, it wrecks credibility, literally in the first sentence of the article

In the style of Benjamin Buford "Bubba" Blue:
"You got your cold brew, your Japanese iced coffee, your iced americano. Then there's your mazagran, that's coffee with lemon juice, real refreshing. Your espresso tonic. Your iced latte, iced cappuccino, iced macchiato. You got your iced mocha, your frappuccino, your Greek frappé. Vietnamese iced coffee with the condensed milk dripping down real slow. Affogato, that's espresso poured right over ice cream. That's... that's about it."
