 The word "tachyon" has become widely recognized to such an extent that it can impart a science-fictional "sound" even if the subject in question has no particular relation to superluminal travel (compare positronic brain).Classic Anime fans may associate tachyons with the energy source for the wave-motion gun and wave-motion engine in "Space Battleship Yamato" ("Starblazers" in the United States).Further examples include the "Tachion Tanks" of the PC game "" and the "tachyon beam" of the game "Master of Orion."
