I used sound waves to make espresso. It could cut coffee-brewing energy use by 75%

‘Ultrasonic espresso’ made with cold water and high-frequency sound waves uses less energy than the traditional version – and taste tests show it’s just as good.

    Saving up to 75% of energy by not heating the water is a minor benefit for home users or small coffee shops. But for companies making ready-to-drink coffee products at industrial scale, it could be very significant indeed.

    I guess if you like iced coffee it is a win for that also :)

    Looks legit, especially for cold brews.

      Definitely a unique approach to coffee making. I was thinking how you do generally want coffee to either be cold or hot, room temperature is the one temperature that just doesn’t work.
