A guided-transportation system intended for Paris, Aramis represented a major advance in personal rapid transit: it combined the efficiency of a subway with the flexibility of an automobile. But in the end, its electronic couplings proved too complex and expensive, the political will failed, and the project died in 1987.<BR>The story of Aramis is told by several different parties, none of which take precedence over any other: a young engineer and his professor, who act as detective to ferret out the reasons for the project's failure; company executives and elected officials; a sociologist; and finally Aramis itself, who delivers a passionate plea: technological innovation has needs and desires, especially a desire to be born, but cannot live without the sustained commitment of those who have created it.
