Roger,

I still cannot find that E-mail, so don't know what happened to it.

Also, I really don't deal in EMF propulsion.  The conventional electromagnetics theory assumes a flat spacetime, hence no curvature of spacetime, hence no "inertial force", "gravitational force", etc. from electromagnetics.

A higher group symmetry EM, such as O(3), can model the two missing ingredients in the supersystem.  The supersystem consists of the system and its dynamics, the local curvatures of spacetime and their dynamics, and the local active vacuum and its dynamics.  All three components of the supersystem interact with each other.  By using such a better model, one then can directly model the interaction between system dynamics and curved spacetime (gravitation and production of anomalous force such as anomalous thrust), system dynamics and the active vacuum (positive and negative energy aspects etc.) and the active vacuum and curvatures of spacetime (interaction between quantum effects, fields and gravity, etc.).

In my view it is a straightforward problem that is solvable.  Based on that approach in its earlier state, I postulated the mechanism for antigravity in 1971 while in graduate school at Georgia Tech.  Some years later I convinced Sweet to do the experiment (it required an overunity EM power system with extreme gain, and his had 1,500,000 COP).  So by pushing it and doubling the gain, the experiment could be done.  The experiment was performed, and it worked beautifully, steadily reducing the weight of an object on the bench by 90%.

An entire chapter of my new book, Energy from the Vacuum, is devoted to antigravity (my view, of course).

Best wishes,

Tom Bearden
