Hands-On With A Whippit-Powered Travel Espresso Maker
A typical regulator might be two inches in diameter. Much too large for the TWIST. The task of shrinking the apparatus down without losing efficiency and safety went to Gecko, a firm that collaborated on the Herman Miller Leaf Lamp and has built pneumatic devices on cruise control missiles for defense industry contractors (really).
Their creation: a regulator that's about the size of half a grown man's pinky nail. Once the pod develops its own pressure, the regulator in the handle shuts off the pressure. And there's also a secondary safety valve, in case you put in too much coffee. In time, too, their small, main regulator could be applied or licensed out to other hardware.
For now, O'Brien is focused on the TWIST. And as we continue to chat, all I'm focused on is the taste. He takes a preloaded cup, gets some hot water from the cafe, puts in 3.5 oz., pulls the trigger to release the gas (it's cold, but expands rapidly from the hot water), and begins the pour...
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
