Electromagnetic Field Gravitational Solution

http://www.modernrelativitysite.com/chap7.htm
I found the exact solution to Einstein's field equations for the gravitation of an arbitrary static electric field as well as for a uniform magnetic field and discuss its implications regarding field propulsion technology like the lifter.

My solution is both for free space and the interior of the fields source, but I'm not certain how the introduction of dielectrics would perturb the solution.

Possible facepalm question here but how would the acceleration act on the Lifter wire / body? I understand the ion wind thrust is simply the result of Newton's 2nd and 3rd laws, but your a=4piGe0|E| is the acceleration of what and where exactly? It should be possible to measure this acceleration in isolation from ion wind by placing a Lifter in a vacuum although experiments by NASA are not so encouraging, see gltrs.grc.nasa.gov/reports/200­4/CR-2004-213312.pdf

@khyar

Its the acceleration of any neutral test particle released into free fall. The atoms of the wire will be affected just as any test particles. NASA is a political organization.

@WaiteDavidMSPhysics .... the resulting forces could be rather impressive even in the regions far from the wire where |E| is not as high as 14GV/m. In fact to get a=9.8m/s^2 in the BaTiO3 dielectric |E| only needs to be 1.4MV/m. I think an experiment is in order where a Lifter is encased in a BaTiO3 dielectric in vacuo. This would be a direct test of your new solutions too. What do you think? It would also serve as a means of determining the sign of the acceleration with respect to the E field.

@khyar Feel free to do any experiments. But, you don't test solutions. You check them. It is the theory, in this case general relativity, you are testing when you see if its solutions are accurate models of nature. I'm not much of a tinkerer, better at doing the math.

@WaiteDavidMSPhysics Yes, quite true ;-). By the way did you get the preceeding comment about modification of acceleration by increasing the relative perimittivity of the medium around the lifter? Only if the line of reasoning regarding the scaling of the acceleration by the relative permittivity (er) is valid would it be worth doing the experiment. I presumed that your equation is for free-space and then suppose that in an isotropic, homogeneous dielectric medium it becomes a=4piGe0er|E|.

Fascinating. I am not familiar with Einstein's field equations but I find this equivalence between mass and charge to be most interesting, and possibly quite important for understanding devices like the Lifter and future propulsion methods. Indeed it is encouraging that 114GV/m can be made to occur in the vicinity of a thin wire, and I guess the electric field approach is still the more practically feasible method as opposed to using an equivalent magnetic field which would need to be 380T!....
