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.

Famous quotes containing the words practical and/or attempts:
“Missionaries, whether of philosophy or religion, rarely make rapid way, unless their preachings fall in with the prepossessions of the multitude of shallow thinkers, or can be made to serve as a stalking-horse for the promotion of the practical aims of the still larger multitude, who do not profess to think much, but are quite certain they want a great deal.”
—Thomas Henry Huxley (1825–95)
“There is hardly an American male of my generation who has not at one time or another tried to master the victory cry of the great ape as it issued from the androgynous chest of Johnny Weissmuller, to the accompaniment of thousands of arms and legs snapping during attempts to swing from tree to tree in the backyards of the Republic.”
—Gore Vidal (b. 1925)
