Practical Attempts
One of the first engineering descriptions of an "Electric Gun" appears in the technical supplement of "Zero to Eighty" by "Akkad Pseudoman", a pen name for the Princeton physicist and electrical entrepreneur Edwin Fitch Northrup. Dr. Northrup built prototype coil guns powered by kHz-frequency three phase electrical generators, and the book contains photographs of some of these prototypes. The book describes a fictional circumnavigation of the moon by a two-person vehicle launched by a Northrup electric gun.
Later prototype mass drivers have been built since 1976 (Mass Driver 1), some constructed by the U.S. Space Studies Institute in order to prove their properties and practicality. Military R&D on coilguns is related, as are also maglev trains.

“The ordinary literary man, even though he be an eminent historian, is ill-fitted to be a mentor in affairs of government. For ... things are for the most part very simple in books, and in practical life very complex.”
—Woodrow Wilson (1856–1924)
“Because the soul is progressive, it never quite repeats itself, but in every act attempts the production of a new and fairer whole.”
