The scientific validation of a science that connects gravity to electricity usually could face an uphill, skeptical battle. This has been true of the 1994 publication of Electrogravitics Systems: Reports on a New Propulsion Methodology by Thomas Valone. Finally, eleven years later, a follow-up second volume called Electrogravitics II: Validating Reports on a New Propulsion Methodology has just been released which contains journal articles by the Army Research Lab and Honda Corporation on their experiments and theory of how electrogravitics can work, besides patents by NASA and others. In addition, the author introduces the subject with a discovery that the classical "electrokinetic field" equation can predict how and why pulsed electrogravitics will work best. He also explains in his article that the historic T. Townsend Brown experiments which led to the "Biefeld-Brown Effect" actually comprise electrogravitics and electrokinetics, which differ from each other. --With Science, Historical, Testimonial and Patent Sections, the book appeals to various audiences very well. For those who are interested in the details of the history, a complete reproduction of the three-part series on "Conquest of Gravity: Aim of Top Scientists in the U.S." is included, which appeared in the N.Y. Herald Tribune, November 20-22, 1955.
