Yes, there is a connection to Tesla's radiant energy work, and a close colleague and I will have something very definitive to say on that subject in a few months. Just now it's been a nondisclosure situation for some time and so I cannot talk openly about it yet. For a good indication of the mechanism that generates practical antigravity, see that Chapter in Energy from the Vacuum that deals with antigravity. Also, read again the results achieved by the Sweet VTA antigravity test, where 90% of the weight of the system was reduced on the bench. Sweet's device outputted mostly negative energy, not positive energy. Excess positive energy of local spacetime in which an object is imbedded leads to excess positive mass-energy, which is a positive (attraction of mass-energy) gravitational effect. Excess negative energy of local spacetime in which an object is imbedded leads to the addition of negative mass-energy to the normal positive mass-energy, thereby reducing the attraction of mass effect and reducing its positive gravitational response. If the negative mass-energy is equal to the positive mass-energy, that is zero gravitational (attraction of mass) condition, and the system hovers weightless. If the negative mass-energy exceeds the positive mass-energy, that is negative gravity (antigravity) condition and the system levitates and moves upward (repelled by the mass of the earth). Etc. Anyway, a charged capacitor in fact has a difference in energy density across its plates, and therefore in its local embedded vacuum between those same two plates. In short, it exists in an asymmetrical vacuum and asymmetrical spacetime curvature. Hence such capacitors can indeed exhibit a unilateral force, purely by its local curvature of spacetime. The electrical theory of course assumes that the charged capacitor is in flat spacetime nonetheless, which is false. So that model predicts no such gravitational effect. As we stated in Energy from the Vacuum, classical EM and electrical engineering assume away the other two components (active vacuum and active curvatures of spacetime) of the SUPERSYSTEM, and retain only the physical system. So it NEVER predicts an antigravity effect, because it is a seriously restricted and "approximate" model only -- useful for those cases where the vacuum is not too asymmetrical and the local spacetime is not too appreciably curved. But once the local spacetime is curved, a cyclic motion can be discreetly moved to produce a unilateral force. To check this, see Steven K. Blau, “The Force Need Not Be With You: Curvature Begets Motion,” Physics Today, 56(6), June. 2003, p. 21-23. Cycle deformations can alter the free-fall motion of a composite body as it moves through curved spacetime. In curved spacetime, a swimmer executing an appropriate cycle of internal changes can move, even without external forces. [For the technical article, see J. Wisdom, Science, Vol. 299, 2003, p. 1865.]. So the requirements for practical antigravity (and unilateral propulsion) are: (1) a curved local spacetime in which the vehicle, object, or system is embedded, and (2) appropriate cyclic motions of the system which then produces the unilateral thrust or the unilateral lift, or both. We also point out that, when the long-ignored giant Heaviside component of EM energy flow is accounted again as well as the standard Poynting EM energy flow, then one has lots more "EM energy" to work with -- often a trillion times as much -- as the conventional theory specifies. If the Heaviside component is properly used, then the "significant curvature of local spacetime" is not so hard to do electromagnetically after all. Hope this helps. Best wishes, Tom Bearden
