Hackworth put Cotton's document atop the Runcible stack and guillotined 
it against the desktop a couple of times, superstitiously trying to make it 
look neat. He carried it to the corner of his office, over by the window, where 
a new piece of furniture had recently been rolled in by the porter: a 
cherrywood cabinet on brass casters. It came up to his waist. On top was a 
polished brass mechanism—an automatic document reader with detachable 
tray. A small door in the back betrayed a Feed port, one-centimeter, typical of 
household appliances but startlingly wimpy in a heavy industrial works, 
especially considering that this cabinet contained one of the most powerful 
computers on earth—five cc's of Bespoke rod logic.
It used about a hundred thousand watts of power, which came in over the 
superconducting part of the Feed. The power had to be dissipated, or else the 
computer would incinerate itself and most of the building too. Getting rid of 
that energy had been much more of an engineering job than the rod logic. The 
latest Feed protocol had a solution built in: a device could now pull ice off 
the Feed, one microscopic chunk at a time, and output warm water.
