I don't know if you looked at that gravity coil schematic I posted, but it's been floating around on BBSes for decades. Here's what it says:

>You are probably thinking, "how can gravity possibly be resonant?" This is a good question. As discovered by Thomas Townsend Brown, electricity is directly related to gravity (see his U.S. patents 1,974,483, 3,187,206 in particular.) If this is so, it is most likely a vectorial relationship (law of opposites), and since there is already an electromagnetic vector (2 dimensional), a gravitational vector would be at 90 degrees to both the magnetic and the electric vectors (since we are in a 3 dimensional space.) The gravitational vector is like the "duration in time" of the electric and magnetic vectors. There are also, in addition to scalar electric and magnetic waves (see Bearden, Thomas E. "Toward a new electromagnetics: part IV: vectors and mechanisms clarified. Tesla Book Co., Millbrae, California, 1983. This work, however, fails to mention gravity waves, although it does mention controlling gravity), there are also scalar gravitic waves (see Ford, L.H and A. Vilenkin. "A gravitational analogue of the Aharanov-Bohm effect." Journal of Physics A. Mathematical, Nuclear, and General. (Great Britan). 14(9), Sep. 1981. p. 2353-2357.)
