Wouldn't it be cheaper to brew the coffee in a sealed/vacuum chamber instead? Whatever machine they're using to generate "acoustic cavitation" doesn't sound cheap.

That was my first thought. It seems like others have already tried it with good results.

You can also sous vide coldbrew coffee for faster results than traditional coldbrew. But at that point is it still technically coldbrew? Maybe warmbrew is a better term for it.
