On another occasion, Trurl and Klapaucius are captured by an interstellar "PHT" pirate. Trurl offers to build a machine capable of turning hydrogen into gold (something he can do manually, which he demonstrates by hand, mixing up protons and putting electrons around). However, the pirate turns out to have a PhD and cares not for the riches, but for knowledge (and in fact points out that gold becomes cheap if it is abundant). Trurl therefore makes a modified Maxwell's demon for him, an entity that looks at moving particles of gas and reads information that is, coincidentally, encoded in their random perturbations. This way, all the information in the universe becomes easily available. The demon prints out this information on a long paper tape, but before the pirate realizes most of the information is completely useless (although strictly factual) he is buried under the endless rolls of tape, ceasing to bother anyone.
