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.

      So this is a method to make crap in a bottle or can.

      Gotcha.

      I’ll stick with the trusty French Press

      Edit: …Though I gotta admit it’s pretty dang cool that they figured out a new way to brew coffee using cold water and reduce the energy use of large scale production.

          Just because they’re doing this to chase money to fund their research doesnt mean it couldn’t potentially make a better cup or coffee at home. I think its a britllant idea where heat makes the coffee bitter, perhaps there’s a magic ratio of heat and ultrasound to make a majestic cup of Joe.

          The spaceage of espresso machines. Heat generation is expensive in space, when the opportunity cost is the atmo circulation. This could be the answer to a problem we haven’t yet run into as a species. I dig it.
