So this is a method to make crap in a bottle or can.
Gotcha.
I'll stick with the trusty French Press
Edit: ...Though I gotta admit it's pretty dang cool that they figured out a new way to brew coffee using cold water and reduce the energy use of large scale production.
Just because they're doing this to chase money to fund their research doesnt mean it couldn't potentially make a better cup or coffee at home. I think its a britllant idea where heat makes the coffee bitter, perhaps there's a magic ratio of heat and ultrasound to make a majestic cup of Joe.
An edit to my post got lost in the aether as I entered a dead zone at work, on reflection it is cool tech.
I'm skeptical about inviting more tech into the home for something so simple in this day and age of subscription services and lack of repairability, but if it makes a better cup of coffee, I'd try it.
Exactly. This is meant to save corporations money, to increase profits.
