“…The possibility of altering the equivalence principle (which equates the two), has been pursued diligently by Dr. James Woodward (Figure 1) [13]. His prediction, based on Sciama's formulation of Mach's Principle in the framework of general relativity, is that "in the presence of energy flow, the inertial mass of an object may undergo sizable variations, changing as the 2 nd time derivative of the energy" [14]. Woodward, however, indicates that it is the "active gravitational mass" which is being affected but the equivalence principle causes both "passive" inertial and gravitational masses to fluctuate [15].…”

Electrogravitics and electrokinetics can be traced to T. Townsend Brown's first article "How I Control Gravity" (Science and Invention, 1929) with the unexplained alignment of the "molecular gravitors". Brown reported that the dielectrics had high propulsive force when the "differently charged elements" were aligned with the voltage source. Perhaps electrogravitics was also revealed in the article "Gravity Nullified: Quartz Crystals Charged by High Frequency Currents Lose Their Weight" which appeared two years earlier in the same magazine in September of 1927. The editors had a change of heart however, in the following issue, they rescinded the article. Much of what we know about T. T. Brown is from his numerous patents and articles, reprinted in Electrogravitics Systems Volume I, by this author who was fortunate to correspond with him in 1981 when he was at the University of Florida. A sample of his detailed correspondence is contained in the out-of-print book, Ether-Technology: A Rational Approach to Gravity-Control by Rho Sigma (1977) and in the recent Defying Gravity: The Parallel Universe of T. Townsend Brown, Paul Schatzkin, (2009, Embassy Books). Also, a five-minute Brown-Bahnson Lab video online shows many of the experimental models that Brown developed toward 1960 with colleague Agnew Bahnson (http://www.youtube.com/watch?v=Rp4hygoD3RU).

“…Conservation of momentum is satisfied by evoking interpretations of Mach's principle. Independent verification experiments, using techniques less prone to spurious effects, were unable to reliably confirm or dismiss the claims [Cramer 2004]. Woodward and others continue with experiments and publications to make the effect more pronounced and to more clearly separate the claimed effects from experimental artifacts.…”

: The term, propulsion breakthrough, refers to concepts like propellantless space drives and faster‐than‐light travel, the kind of breakthroughs that would make interstellar exploration practical. Although no such breakthroughs appear imminent, a variety of investigations have begun. During 1996–2002 NASA supported the breakthrough propulsion physics project to examine physics in the context of breakthrough spaceflight. Three facets of these assessments are now reported: (1) predicting benefits, (2) selecting research, and (3) recent technical progress. Predicting benefits is challenging, since the breakthroughs are still only notional concepts, but energy can serve as a basis for comparison. A hypothetical space drive would require many orders of magnitude less energy than a rocket for journeys to our nearest neighboring star. Assessing research options is challenging when the goals are beyond known physics and when the implications of success are profound. To mitigate the challenges, a selection process is described where: (1) research tasks are constrained to only address the immediate unknowns, curious effects, or critical issues; (2) reliability of assertions is more important than their implications; and (3) reviewers judge credibility rather than feasibility. The recent findings of a number of tasks, some selected using this process, are discussed. Of the 14 tasks included, six reached null conclusions, four remain unresolved, and four have opportunities for sequels. A dominant theme with the sequels is research about the properties of space, inertial frames, and the quantum vacuum.

“…Unfortunately, when subsequent publications by Woodward indicated that the effect was much smaller than originally reported [22], the independent test program had to be changed. The revised experiments were unable to resolve any discernable effect with the available resources [23]. Woodward continues with experiments and publications [24], and has begun addressing the theoretical issues identified during this independent assessment.…”
