In most home-brewing setups, each step in the process requires moving the beer to a new container by hand, which increases the chance of contamination and requires you to lift stuff. 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.
