Researchers at UNSW Sydney have harnessed the power of ultrasonic sound waves to make espresso-strength coffee with room temperature water, cutting energy use by up to 75%.
I found one for sale that does 40k that has the same form factor as the one shown in the paper. I almost want to make a high-speed coldbrew system but I don’t expect it’d be worthwhile for the coffee, only maybe for the fun of building it.
Yeah basically, but at a much higher frequency since it’s ultrasound. Human hearing tops out at 20khz, and this would be close to 50khz

Lol worst case you can convert it to an ultrasonic parts cleaner
