That’s a very good point, I’d wager that the energy input cost for industrial scale coffee brewing is a larger portion of the overall cost than it is for a shot pulled in a cafe. Reducing input energy by 75% in that case is huge, it’s like switching from resistive heating to a heat pump, any operator would jump at the chance to save that money if the process time is comparable and the ultrasonic brewing equipment plus lower energy costs has a lower amortized cost than the existing plant.
