    I agree this is the kind of thing I should find on YouTube, not in an academic journal. But the paper does go into a lot of detail about extraction efficiency, so I guess there might be some useful measurements.

    I am curious about the taste. It should be somewhere in between cold brew and hot, but probably closer to cold. Cavitation is a violent process. On a micro scale it’s literally boiling. Then the steam bubble collapses and is instantly cooled because of an almost infinitely big heat sink. So when cavitation occurs near the coffee grounds, some of the extraction would be at much warmer temperatures, for a brief instant.

      Oh, yes, I was making fun of the headline, about inventing.
      With that in mind basically any experiment/measurement/scientific theory is some sort of invention, it’s just that we dont call it that.

      Like, nobody invented the concept of tank, ppl “invented” materials, equipment, manufacturing & logistics/admin processes, etc that at one point allowed for a feasible “tank” to be compiled.
