Carr used mercury. There is research about mercury being used for antigravity purposes that one can find in an online search. Mercury can be vaporized and was used in ancient pyramids around the world as a thousand-year light source. Its poison can explain why people died after opening ancient pyramids. Mercury has been found in pools on the floor of pyramids.
Similar to a plasma jar or vacuum tube, mercury plasma can be used in an utron, vaporized by the consequences of a hard vacuum and applied charge. Mercury in a toroid shape in an utron, contained in a non-permeable housing perhaps lined with a coating of glass or gold (mercury may penetrate through aluminum), would be about the only logical way Carr could have applied mercury to his design.
Some experiments from some companies involving mercury show levetation and the heavy atom of mercury to act in ways similar to a condensate where all individual atoms work in harmony together as a unity of a singular inertial force.
The utrons provide a spinning and rotating ionized mercury plasma force, which is an aspect required for warp drive in current research. Such is not limited to just utrons, but can be used in the vertical core.
Similar to a Bose-Einstein condensate, harnessing the inertial force of all atoms aligned in charge and inertial acceleration, as one large force.
Negative energy (Negative energy is magneto-electrostatic energy obtained from the spark collapse of an electromagnetic field; mass is electromagnetic) powers the formation of the ionic spin of the mercury plasma.
It's a recipe for warp drive. See the article "Harnessing Negative Energy" on the Tesla / Free Energy page of this website. Negative energy is required for warp drive, according to Alcubierre.
. . .
The simplest solution is to make the outer ring another utron ring that spins opposite in direction to the lower OTC-X1 disk to include co-counter-rotational gyroscopic inertial forces of negative energy mercury plasma in conjunction with gravity cancellation. It does not have to employ the same rotating electromagnet configuration as in the OTC-X1, as per the Outer Ring page describes.
This along with the power source described on the Tesla / Free energy page article "Harnessing Negative Energy" completes the design of a transverse magneto-electrostatic mercury-plasma warp drive starship.
I would like to note the similarity of the Outer Ring design to a rail gun also.
It should be obvious that this an adaptable design. The outer ring can be built exactly as the OTC-X1 outer electromagnet / utron peripheral, or otherwise. The outer ring page discusses possibilities of an electrostatic collapse, which amounts to one VERY important thing: when negative energy is already in use, and sent through the field electromagnets which pulse and collapse, then an additional dimension of negative energy is obtained.
What happens when an electromagnetic field collapse is used in a coil and collapsed again?
That would be a new mechanism of pure negative energy usage that is as of yet discovered, but is logical in function to generate a pure and true warp field.
Casimir Plates and Negative Energy
After some consideration, I want to add this as a design update.
FIRST OF ALL, Casimir Plates won't work. They have to be di-electric plates. The simple reason for it is at the bottom of the "Tesla Power" article on the Tesla/Free energy page. Di-electric plates actually hold usable energy that can be used to bend and warp and compress SPACE.
Regarding the possibilities of pulsed negative energy in resonance between Casimir (di-electric) plates:
That is something others have worked with and have had success. I almost had to sign a nondisclosure to view that but ... the reason I bring it up is to show how a similar application can be used in the rail design of the outer ring, but can be used with curved reflective longitudinal plates, with rails, which is more efficient as an engine design.
Since this is being applied in an engine, I'll go over some brief engineering aspects:
... Two sets of curved Di-electric plates focused to a common center. That can be expanded into a ring. ...
Such arrangement is for a resonating energy build up when once resonance is at peak will provide continuous non-stop power used for negative energy applications, not a specific design for an electromotive accelerator. Acceleration of that energy can be achieved by rails with some aspect of inductive force.
The set of double Di-electric plates works with alternating negative energy fields (negative AC). They have to be far enough apart that a spark wont arc; AND since they are in parallel although curved, there is no real shortest point of distance allowing for a spark discharge.
It carries more surface area than bare wires spaced evenly apart. Recall that amps equates to a volume of a scalar space of energy.
Such a thing can replace the outer electromagnets in an outer ring system set up to equate to the OTC-X1 style. No electromagnetic collapse is required since the energy run through the plates is already a negative energy density. It is more efficient.
The outer electromagnets in the OTC-X1 induce a rotation of the central disk (accumulator frame). Although what has been shown to me involves resonating energy build-up in a power generating application, a type of electromotive application can be possible since it is dealing with a magneto-electrostatic field, and a magnet produces an inductive motive force. Since a negative-energy magneto-electrostatic field is present, then Curved di-electric plates can be an upgrade, and a design improvement to a rail-driven type of design as seen on the Outer Ring page.
Using Mercury-Plasma utrons on a drive ring like the OTC-X1 central accumulator frame disk, but a narrow disk that only inhabits the outer perimeter area of the Outer Ring section of the LAU-X3, would give us a 100% Negative Energy Outer Ring region, instead of a positive-energy driven electromagnetic coil that must collapse and build repeatedly around the perimeter. This could provide better warp field stability.
Warning: DO NOT use aluminum utrons with mercury. Mercury dissolves aluminum on contact. Best to use copper.
