"The inner hull is covered on it's outside by wedge shaped thin metal sheets of copper or aluminum, bonded to the ceramic. Each sheet is 3 to 4 feet wide at the horizontal rim of the hull and tapers to a few inches wide at the top of the hull for the top set of metal sheets, or at the bottom for the bottom set of sheets.
Each sheet is separated on either side from the next sheet by 1 or 2 inches of uncovered ceramic hull. The top set of sheets and bottom set of sheets are separated by about 6 inches of uncovered ceramic hull around the horizontal rim of the hull.
The outer hull protects these sheets from being short-circuited by wind blown metal foil (Air Force radar confusing chaff), heavy rain or concentrations of gasoline or kerosene fumes.
If unshielded, fuel fumes could be electrostatically attracted to the hull sheets, burn and form carbon deposits across the insulating gaps between the sheets, causing a short-circuit.
In space, the outer hull with a slight negative charge, would absorb hits from micro-meteorites and cosmic rays (protons moving at near the speed of light).
Any danger of this type that doesn't already have a negative electric charge would get a negative charge in hitting the outer hull, and be repelled by the metal sheets before it could hit the inner hull.
This wouldn't work well on a very big meteor, I might add. The hull can be made in a variety of shapes; sphere, football, disc, or streamlined rectangle or triangle, as long as these metal sheets, "are of considerable area and arranged along ideal enveloping surfaces of very large radii of curvature," p. 85. My Inventions, by Nikola Tesla."

"An anti gravity system with a hallow metal sphere (7) placed inside a very strong hallow outer metal sphere (1) with a clearance in between the two and the outer sphere having a sump at bottom"
"Buoyant force is a powerful force in nature which actB opposite to gravitational force. If we combine these two laws we arrive at a system as βhown in FIG[ 1] in which there exist an outer hallow sphere and an inner hallow sphere is placed inside the outer sphere and water is filled in between the two. The inner hallow sphere applies a buoyant force over the inner face of the outer sphere equal to the weight of water displaced by the inner sphere. But if we weigh this system weight is not changed, This is due to the additional hydraulic forces acting in the system.Now let us imagine what happens when heat is supplied to the water in between the two spheres. The temperature of water is gradually increased and when it exceeds the boiling point of water pressure increases in the system and the pressure tries to push the inner hallow sphere to the centre of the outer hallow sphere. At this moment the hydraulic forces of the system cease to exist. When the temperature increases the inner sphere applies a force over the inner face of the outer sphere and the system now looses it's weight depending on the pressure and temperature of the matter in between the hallow spheres and the system is called the "anti gravity system"."
"The outer face of the inner sphere [7] and the inner face of the outer sphere are coated with material which is highly resistant to temperature and non conductor of heat."
"When heat is not supplied to the liquid in between the spheres the inner sphere will be applying a force over the inner face of the outer sphere but the weight of the system does not change due to the static hydraulic forces acting on the system. When generator unit is started the electric coil is heated and the matter in between the spheres is heated to a high temperature. When the temperature increases the dynamic pressure increases in the liquid and this pressure tries to push the inner hallow sphere to the center of the outer hallow sphere and the static hydraulic forces which exist before the application of heat cease to exist and the system looses it's weight depending on the temperature of the fluid and the dynamic pressure developed in the system due to the application of heat. The dynamic pressure developed is a function of the temperature produced. Hence the lifting force achieved is a function of the material used in between the spheres."

"a frequency generator, antenna and coaxial cables to drive the antenna array (1 d).
To create, by claims (1 a, 1 b, 1 c), an intense vertical line charge at the corners (1 b) and a horizontal electric field that that is parallel to the sides of the hull (1 a);
To create, by claims (1 d,1 e), an electromagnetic wave with a vertically polarized electric field traveling outward from the side of the hull (1 a); and
To create, by claims (2,3), an interaction of the electrostatic field (2) with the electromagnetic wave (3) such that a combined spacetime curvature pressure is generated on the hull in the upward and forward direction to produce lift and propulsion respectively."
"This invention is a spacecraft with a triangular hull having charged flat plates on the vertical corners of the three sides. The two rear corners are charged to a potential V. The forward corner is charged to a potential −V. The 60° angle on the corner creates a line charge density singularity that produces a huge horizontal electric field pointing from the back to the front of the craft which is also parallel to the sides of the triangle. An array of horizontal slot antennas located on the sides of the triangular hull produce an electromagnetic wave with the electric field polarized in the vertical direction. This combination of fields produces a spacetime force in both the vertical and horizontal directions such that the spacecraft receives a lift force and a force of propulsion."
