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:
“History not used is nothing, for all intellectual life is action, like practical life, and if you don’t use the stuff—well, it might as well be dead.”
—A.J. (Arnold Joseph)
“For a novel addressed by a man to men and women of full age; which attempts to deal unaffectedly with the fret and fever, derision and disaster, that may press in the wake of the strongest passion known to humanity; to tell, without a mincing of words, of a deadly war waged between flesh and spirit; and to point the tragedy of unfulfilled aims, I am not aware that there is anything in the handling to which exception can be taken.”
—Thomas Hardy (1840–1928)
