Wonder why they chose to stick with the portafilter form factor rather than something custom for the method. Perhaps it just fits the task well and they don't need to change, or they want to preserve the look of an espresso machine. Though, if the water is room temp, they only really need the pressure, which doesn't need the entire machine. Seems pretty cool.

Edit: The article shows that they chose this method specifically to use the basket, and the basket allows for the vibrations they need. The other conveniences of the basket form factor also come into play; reloading, cleaning, etc. and don't need reinventing or retraining. Cool stuff. I wonder whether they'll remodel the machine around the basket and remove what's not needed if this becomes a product.

Consistency in output - this is a standard test model to replicate entire existing system and then apply changes components of the system to test a theory.
