Electrogravity is easy!
It's as simple as placing a positive high volt charge on one side of a sphere, and a negative high volt charge on the other side of the sphere, and the sphere moves in the direction of the positive charge.
It can be observed the air moving around the sphere and accelerating the air molecules so that it warps spacetime (causing the sphere to move at very high speeds) as Townsend Brown demonstrated in the 1930's. The explanation may be a bit complex, but electrogravity in itself is very, very simple to achieve. "Lifters" made of balsa wood and tin foil and a string of bare wire provide the simplest demonstration.
The first time I saw a lifter was around 2002. Check out www.americanantigravity.com
In light of the new realization of Townsend Brown's work as seen on the "Updates and Design Improvements" page, some new design improvements can be made; and again, are seen to actually already be designed with that geometry in mind.
The Outer Hull plating is layered in three layers. With a technology of a di-electric medium between two charge plates, it can in fact, achieve the desired "warp drive" type of electrogravity flight possible that is being described here in this section, and on this website.
This should be considered firstly, and perhaps an additional layer of outer skin (total of four layers) should be used, to keep carbon build-ups from shorting across the gaps of the electrogravity hull plates when in an atmosphere.
With that in mind, the below portion is how Grand-daddy used to do it.

In regards to electrogravity hull plating, it has been noted the use of a ceramic skin around the ship overlaying electric charge plates. The ceramic will conduct a magnetic field, and prevent charge plates from building up carbon between the plates, shorting them out. However, having charge plates also on top of ceramic plates will also conduct magnetic fields, if they are constructed of more ferrous material.
A couple of posts below, these things are discussed more as layers of auxiliary redundant engine dynamics.
A good ship design ought to be able to test all aspects of all questions, until the answer is found, in developmental construction.
Each electric charge plate can be separated by an air space; periodic cleaning of the plates would merely be routine maintenance.
Field permeability can be determined with more of a complex multi-faceted overlapping of materials. More plates all around the ship will increase the frequency of any energy field generated cyclically. Where the positive charge is on the ship, in opposite to the negative, in a basic concept determines which direction the craft will move.
This type of electrical "merging" with the atmosphere of a planet can allow for ultimate maneuverability as the craft is also vibrating in a much higher frequency perhaps outside the range of the visual light spectrum.
Atmospheric braking, quick 90-degree turns, super-acceleration and speed is what electrogravity is made for. More on electrogravity is discussed below.
The power for an external electrogravity system can come from the outer ring drive alone, without engaging the vertical core while in atmosphere.
I've been working on this for the last 13 years, determining if these things are possible. According to physics, this is very easily achievable.
