Anti-Gravity US Navy Spacecraft using Mass Reduction & Non-Conventional Propulsion

Warning: This article presents information about a compact non-conventional fusion reactor that sounds like it comes from a high-tech Hollywood science fiction production. I suggest you first view the patent filing linked here to verify its credibility before proceeding.

Because the patent was published by the US Navy and is now under a “Pending” approval status, this is the real deal. This is NOT a work of fiction. This patent also seems to coincide as a possible power source for another US Navy patent – the antigravity spacecraft linked above.

The Short Story

The US Navy has approved publication of a patent for a Plasma Compression Fusion Device with the following attributes.

Multi-use: The patent specifically states this is a multi-use power source for:

space, sea, or terrestrial environment; however, this invention can be utilized for any type of application that requires the use of energy generation.”

The above mentioned applications and patent language suggest that this device may possibly also be used as a power source for:

  • a recent and “active” US Navy patent for an antigravity spacecraft that uses repulsive gravity, mass reduction and non-conventional (non-explosive combustion) propulsion. This propulsion possibly means no flames or explosions, but perhaps near-silent electromagnetic field propulsion using power possibly produced by this Plasma Compression Fusion Device.
  • mile-long space carriers as reported by Dr. Michael Salla, Ph.D., who has has published extensive information on secret, suppressed, and emerging technologies as based on official documents and countless testimonies from government, military, and high-tech officials who claim to have developed and witnessed these and similar technologies.

Compact: Just how compact? While the patent does not specifically give the smallest possible rendition of this technology, it suggests that it may be smaller than 0.3 meters in diameter.
Editor’s note: In an unconfirmed statement from a video interview source hosted by a non-conventional news source (not cited here) hinted at “shoebox-sized” technology.

Powerful: The system produces a surplus of energy upwards of the order of 1018. In long-form math terms, assuming the system required 10 watts of input energy to start, the resulting ideal system output equivalent would be 10,000,000,000,000,000,000 watts.

Fuel Derived from Ocean Water: The device’s fuel is Deuterium (heavy Hydrogen), which can be abundantly extracted from sea-water – hence a “virtually limitless” fuel source.

Safe(?): The device as discussed uses only ionized Deuterium gas as a fuel source. This seems to imply the discharge of a waste gas, and no solid fuel. The size and other features of this device suggest the possibility for safe containment of excess heat, electromagnetic, neutronic, gamma-ray, and other forms of radiation that could be harmful if exposed to humans and other living organisms. Given that conventional (plutonium, barium, and other) nuclear fuel sources are solid and produce solid fuel waste, the gas-based fuel source this patent cites might possibly mean easier containment.

The Long Story

The US Patent and Trade Office (PTO) on or about January 22, 2020, has granted to the US Department of the Navy a “Pending” status to item US20190295733A1, which is a Plasma Compression Fusion Device.

This patent is categorized as G21B1/05 Thermonuclear fusion reactors with magnetic or electric plasma confinement.

The abstract for the patent states:

“A plasma compression fusion device which includes a hollow duct and at least one pair of opposing counter-spinning dynamic fusors. The hollow duct includes a vacuum chamber disposed within the hollow duct. Each dynamic fusor has a plurality of orifices and an outer surface which is electrically charged. In combination, the pair(s) of dynamic fusors create a concentrated magnetic energy flux and electromagnetic radiation within the vacuum chamber, whereby the concentrated magnetic energy flux compresses a mixture of gases that are injected through the orifices to the vacuum chamber such that a plasma core is created, and the to electromagnetic radiation heats the plasma core, while produced magnetic fields confine the plasma core between the dynamic fusors, such that when an additional mixture of gases is introduced into the plasma core through the orifices, an energy gain is created.”

Different from “Conventional” Thermonuclear Fusion

The patent Background (Sections 002 – 0004) begins to provide an argument for the differentiation of this patent’s technology from “conventional” thermonuclear fusion:

  • Defining thermonuclear fusion as known now by the scientific community. (Section 0002)
  • Defining the the three primary methods of confining plasma in order to make the ions fuse. (Section 0003)
  • Stating the practical limitations of these methods of plasma confinement. (Section 0004).

Foremost in anyone’s mind is the issue of safety, which is discussed later in this article.

Surplus Power Gain

The patent specifically states the key problem with conventional thermonuclear power generation is that it does not produce a surplus of power, but merely converts power from a solid fuel (like nuclear rods) into another form of solid while releasing heat.

None of these confinement methods to date have been able to achieve break-even fusion reactions, namely the condition for fusion power output to equal the power input, let alone achieve the ignition condition whereby a fusion plasma burn is self-sustained, without need for external power input. As a result, there is a need for an effective plasma compression fusion device, which creates an energy gain.(Section 0004)

The Summary (Sections 0005 – 0012) provides a physical description (0005) and the advantage provided by this design (0006), which generates energy gain by plasma compression-induced nuclear fusion. Power produced in the gigawatt to terawatt range (and higher), with relatively smaller input power in the kilowatt to to megawatt range (see Section 0008).

Just how much energy can be gained? According to the patent (Section 0042), the possible energy gain over the value of input power required to start the system is on the order of 1018. In practical terms, assuming the system required 10 amperes of electrical energy to start, the resulting ideal system electrical output equivalent would be 10,000,000,000,000,000,000 amperes.

Key Design Features

The three drawings accompanying the patent bear individually numbered items to which the patent details refer. The Description (Sections 0013 – 0044) provides details on the device’s design. Here, this article seeks not to analyze every detail, but to point out some major physical design features:

  • Moving parts – Conically shaped counter-rotating parts with multiple orifices through which gases are introduced. These are to be made of Tungsten with high capacitance (such as Tungsten Nitride), whose interiors may include assemblies of electrified grids and toroidal magnetic coils.
  • Vacuum chamber (possibly as fixed non-moving parts) – Used partially for containment of gases (preferably Deuterium gas) rendered to plasma. Reference is made to a “ linear duct configuration” that contributes to the “plasma compression” portion of this device’s name.
  • Open-Source” Layout – The device can be customized for use in either a linear-duct configuration, a cross-duct configuration, or “any type of duct configuration practicable”. In this respect, the device layout is somewhat “open-source” according in a form-fits-function manner.

Fuel Source

The patent cites the preferred use of Deuterium gas provided by an external source, derived originally from ocean water. The gas mixture is described as “fusion fuel” in super-heated conditions within the linear processing duct producing ions which in turn create electromagnetic radiation, which we assume can be harnessed as energy. The patent seems to discourage the use of disparate fuel sources as the design limitations of the system are limited only to the handling of one fuel type.

Fuel Type versus Radioactive Safety

While the fuel is Deuterium based, the patent provides language for the variants of this fuel, and provides caution in not mixing these variants. Depending on the variant, there are radioactivity safety factors to consider.

The fusion fuel (the mixture of gases and additional mixture of gases) can be neutronic or aneutronic. A neutronic fusion fuel can be a Deuterium-Tritium, Deuterium-Deuterium, Deuterium-Xenon mixture, or any gaseous mixture practicable. Both the mixture of gases and additional mixture of gases should be the same of the same chemical composition. The Deuterium-Xenon mixture can produce Xenon-129 with the release of two fast (highly energetic) neutrons which would greatly amplify the power output, however, consideration of the device wall degradation and enhanced radioactivity effects need to be considered from both an operational and a safety perspective. (Section 0028)

Energy Capture Method

The resultant form of energy produced is heat:

Fusion power output may be extracted via conformal heat exchangers (not shown), which are flush with the plasma compression fusion device [item] 10 outer wall (which can be the duct outer surface [item] 116) and carry the neutron produced heat to a thermoelectric generator via a cooling fluid, such as water or poly-alpha olefin (PAO). The mixture of gases and additional mixture of gases (both being the fusion fuel), preferably Deuterium gas, is introduced into the plasma core [item] 75 through the dynamic fusors [items] 200, 230, namely injected through the orifices [items] 205, 235. Deuterium (heavy Hydrogen) can be abundantly extracted from sea-water; hence the ‘virtually limitless’ fuel source idea, that makes this invention extremely beneficial. (Section 0027)

What’s not discussed here is the design for the mentioned thermoelectric generator, which may be fodder for a separate patent not reported here.

What the Patent Does Not Cover

  • Waste / Discharge: While the input fuel is a Deuterium-based gas, one would assume the system discharges a transmuted form of this fuel.
  • Other possible energy capture methods:
    • Thermoelectric: Section 0027 mentions using a thermoelectric generator for heat capture, but the suggested design for such generator is not provided and may possibly be covered by a separate patent.
    • Physical / Motive: Section 0017 alludes to an “ion thruster”, but does not hint whether appreciable power can be captured via this method. Volume of exhaust gas movement is likewise not discussed. The idea in movement of such exhaust gas would be to determine whether sufficient volumes are generated to provide motive force (say, like a jet turbine engine).
    • Electromagnetic: Depending on shielding and other design factors, the system emits electromagnetic radiation, which might possibly be captured, transformed and/or stored in other forms.
    • Electrical charge differential: Perhaps power can be harnessed in electrical form.Section 0018 provides: “… electrons are electrostatically accelerated through a set of two electrical grids 202 (one grid may be a positive voltage charge grid and another negative voltage charged grid, both having the ability to switch electrical charge) exhibiting a potential difference into the plasma core 75, forming a deep (high energy) negative potential well.”

Possible Application: Portable Power

Section 0014 provides:

In the description of the present invention, the invention will be discussed in a space, sea, or terrestrial environment; however, this invention can be utilized for any type of application that requires the use of energy generation.

All dynamic fusor embodiments can be utilized in either the linear-duct configuration, the cross-duct configuration, or any type of duct configuration practicable. (Section 0023)

Written this way, the language seems to suggest this device might serve not only as a multipurpose power source, but also possibly as a more portable power source. How portable? Perhaps the most readily known source of “portable” nuclear power is used in submarines.

Mention of Possible Size

At present there are few envisioned fusion reactors/devices that come in a small, compact package (ranging from 0.3 to 2 meters in diameter) and typically they use different versions of plasma magnetic confinement. Three such devices are the Lockheed Martin (LM) Skunk Works Compact Fusion Reactor (LM-CFR), the EMC2 Polywell fusion concept, and the Princeton Field-Reversed Configuration (PFRC) machine. (Section 0018)


This patent’s design seems disposed for use in the proximity of human users. Conventional and advanced methods may be used to contain heat and provide shielding for possible forms of radiation. Patent language proffers the following:

  • The plasma compression fusion device [item] 10 may be housed in a Faraday cage for reasons of personnel safety. A 10-15 cm thick boron carbide (or Tungsten alloy) shielding which acts as the Faraday cage can also incorporate the cooling channels for the thermal conversion cycle, as well as provide the needed structural support and integrity to withstand the fusion-induced neutron bombardment. Plasma instabilities would be minimized and possibly suppressed by the shearing flows generated by the dynamic fusors. (Section 0026)
  • An aneutronic fusion fuel can, but without limitation, be proton-Boron [item] 11 (for fusion at more than 10× the fusion temperature of the neutronic fuel). In this case there will be no neutrons released, hence no radioactivity dangers arise. For the Hydrogen-Boron fuel, there is a one in one thousand chance of a Gamma-ray channel being formed, which in case of full operational status of the device, would demand great caution. (Section 0029)

Other arguments for safety:

  • Below-mentioned use in aircraft carriers seems to lend further to the argument to the notion of safe use on navy ships.
  • Previous forms of nuclear fusion are predominantly marked by the priority of using them for destructive (life-killing) purposes, whereas the primary purpose of this device is for power generation.

Curious Mention of “Aircraft Carrier” as a Possible Application

The patent curiously mentions:

All these methods of plasma confinement have grave issues, such as an extremely large size (commensurate to that of an aircraft carrier) requirement, plasma instabilities for tokamaks, and power losses and short confinement times for magnetic mirror/cusp machines. (Section 0004)

The New US Space Force? Disclosure of Advanced Technologies?

Assuming special interest groups have long had the funding to develop such technologies, is the recent open and “Active” filing for the US Navy’s spacecraft here an incremental step for the disclosure to the general public of the existence of an already existing secret Space Force?

Among the many items the current US presidential administration is currently addressing, one priority has been on the establishment of a publicly disclosed Space Force. No doubt there are many technologies associated with this industry, and some if not many can be used in this newly established Space Force.

Independent researcher and technologist Dr. Michael Salla, Ph.D. has has published extensive information on secret, suppressed, and emerging technologies as based on official documents and countless testimonies from government, military, and high-tech officials who claim to have developed and witnessed technologies related to this patent. Dr Salla surmises it is possible this patent may be used to power mile-long space carriers.

The compact and open-source multi-use nature of the patent also fosters the use of this tech for innumerable other applications such as:

  • Existing motive technologies such as cars, ships, and public transport.
  • Power for remote locations not currently supported by public utilities.
  • Power for off-world cities and bases.
  • “Clean” power replacement for “dirty” spacecraft explosive propulsion. For example, as a possible power source for the US Navy’s new patent for an antigravity spacraft


This article discusses only several of the many intriguing concepts the Navy patent filing offers.

Hopefully in short time the world may become privy to the real-world manifestation of what this patent really means.
