Perfect for iced coffee though

Better. Perfect would be using chilled water. I'm on a limited connection right now so I can't investigate, but I'm curious to know if they tested.

probably can be done, but ultrasound irradiation itself will warm up coffee a little. if all of it goes to heat, then it's extra 20C or so so you'll have to cool it down afterwards anyway
