What if there were a machine—a beautiful shiny machine—and all it did, with almost no work from you, was make you beer?

Carnett's machine keeps everything in the carts' closed system and requires only that he swap a few CO₂-pressurized hoses to move the liquid along. It also employs a complex temperature-control system to regulate the fermentation (often done in a corner of a basement) to within a degree or two. A couple weeks later, the same system chills the beer on its way from keg to tap, so the Device is always ready with a cold pour and consumes no power when it's not serving or fermenting.
