Category II. Force-Field Propulsion (or lifting)
"The most basic form of force-field propulsion comes to us by way of the Biefield-Brown effect. Originally discovered by Thomas Townsend Brown, who took his findings to the more established Biefield (who publicized them), the effect is named after both men who together made it famous.
But here's the gist of it. When you charge up a rigid flat plate capacitor to sufficiently high voltage (apparently as little as 5,000 volts in some situations), the whole assembly will develop thrust towards the positive plate (and move in that direction if un-impeded). Brown found that the higher the voltage, the higher the thrust. And the higher the dielectric value of the insulator between the plates, the higher the thrust. And apparently, the thrust developed does not particularly "use up" the high voltage used to initiate the effect."

"A spacecraft having a triangular hull with vertical electrostatic line charges on each corner that produce a horizontal electric field parallel to the sides of the hull. This field, interacting with a plane wave emitted by antennas on the side of the hull, generates a force per volume combining both lift and propulsion."
"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 having a triangular hull with vertical electrostatic line charges on each corner. The line charges create a horizontal electric field that, together with a plane wave emitted by antennas on the side of the hull, generates a force per volume providing a unique combination of both lift and propulsion."
"the triangular hull (D) is plotted together with the potential contours (A) and the electric field arrows (B) created by the three corner line charges. The line charges are perpendicular to the paper. Notice that the electric field arrows are parallel crossing the center parabolic antenna (C). The electric field is also parallel to the sides (D) of the triangle.

Referring to FIG. 5, along the side of the triangle (A), an array (B) of horizontal slot antennas emit electromagnetic waves that have a vertically polarized electric E field (C). These traveling waves interact with the electric field (D) produced by the line charges on the corners of the triangle."
"This combination of fields produces a spacetime curvature as determined by Einstein's General Theory of Relativity. The traveling electric field has an amplitude in the vertical z-direction and travels in the x-direction"
"The graphs show that there is a lift force as depicted by the vertical arrows as well as a force of propulsion as shown by the interspersed horizontal arrows. With the passage of time, these vectors exchange places with each other so that the lift becomes the propulsion and vice versa, creating a wavy stress-energy field around the hull."
"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."
