>researchers from the University of New South Wales in Sydney shared their new method for brewing espresso-strength coffee at room temperature, with absolutely no hot water required. Instead, they've swapped out hot water for high-frequency sound waves that they say can do the work of heat and pressure, all in roughly the same amount of time it takes to brew a conventional shot.> As the team explained in the paper, the process works by attaching a small metal device called a transducer to the side of a standard espresso basket. The transducer vibrates rapidly, sending sound waves through the water and coffee grounds and triggering a phenomenon called "acoustic cavitation."From the country that gave the world AC/DC it's a logical invention
>>22075441Espresso is espresso because of the pressure. If this thing isn't producing any pressure then it's not making an espresso.
>>22075456The pressure comes from the music m8
look out Starbucks here comes Spotify
>>22075441italians will not stand for this
>>22075441>heres your $21.99 room temperature bean water because the machine used to make it costs $40,000 + $10,000 a year in service maintenence

>>22075441What a miracle of science. Whats next, toasted bread that uses ice instead of heat? Truly a magical age of innovation we live in.
>>22075456The vibration of the beans pressurizes the espresso.

First the McCafe now this. Australia truly is the coffee place of all the worlds.

And who says Australia doesn't produce Nobel laureates?
>>22075441>Ultrasonic Espressonow your me that coffee should be put on a particle accelerator to increase the flavor and aroma.the absolute state of coffee fags hahahahahaha
>>22075441I did this a long time ago. Yes, it makes really good coffee. The ultrasonic vibration actually emulsifies the fats released from the coffee and makes a latte like texture with no added milk. The retards at uni actually took that long to think of this? KEK
>>22075456Espress your dick in my mouth faggot
