scientists develop ultrasound method in brewing coffee with concentrated sound bursts that heaten up the liquid for espressohttps://theconversation.com/i-used-sound-waves-to-make-espresso-it-could-cut-coffee-brewing-energy-use-by-75-284929Researchers developed an ultrasonic espresso process that uses high-frequency sound waves instead of hot water to produce espresso coffee.The result is an espresso-strength coffee made in under three minutes.Saving up to 75% of energy by not boiling the water to water boil temperatures, is a minor benefit for home users or small coffee shops but it adds to the whole.Imagine every household boiling water at the same time, that would take a lot of energy for a short time.But ultrasonic espresso would not.>The waveform collapseThe key to the new process is ultrasound. These are sound waves above the range of human hearing. In our system, a small metal device called a transducer presses against the side of a traditional espresso basket and makes it vibrate rapidly. Those vibrations move through the water and coffee grounds. This creates a phenomenon known as acoustic cavitation. Tiny bubbles and waves form and collapse in the liquid.
>>537440079Coffee is for cucks.
>>537440171American "coffe" yeah.
For me, it’s a pour over.
>>537440228Just wake up you girl.
Why does it matter to heat with a soundwave instead of a microwave?
>>537440079Just use a perculator.
>>537440302requires less energy I guess
>>537440334Does it?Does it even make better coffee?
>>537440079>an espresso-strength coffee made in under three minutes.But espresso takes 20 seconds to make
>>537440079I grind whole beans and then steep 12 grams for 10 minutes and filter. I'll never go back to using a machine
>>537441079well yeah but your method takes some time and effort
>>537440287kys fatass
>>537441300I'm fat because I don't drink you starbucks????You can't even make this shit make sense.
>>537440079Couldnt I just use a sonic care toothbrush for this?
