...Coated with an electrical charge, the cone-shaped fusors pump fuel gases like Deuterium or Deuterium-Xenon into the chamber, which are then put under intense heat and pressure to create the nuclei-fusing reaction. Current technology at reactors around the world use superconductors to create a magnetic field.
The War Zone reports that the device could potentially produce more than a terawatt of energy while only taking in power in the kilowatt to megawatt range. We don’t currently have an energy source that can produce more power than is needed to create it....

This latest design is the brainchild of the elusive Salvatore Cezar Pais, the inventor of the Navy’s bizarre and controversial room temperature superconductors, high energy electromagnetic field generators, and sci-fi-sounding propulsion technologies that The War Zone has previously reported on. The patent for Pais’ “Plasma Compression Fusion Device†was applied for on March 22, 2018, and was just published on September 26, 2019. The claim states, in part:
"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. [...] These devices feature short plasma confinement times, possible plasma instabilities with the scaling of size, and it is questionable whether they have the ability of achieving the break - even fusion condition, let alone a self-sustained plasma burn leading to ignition." 
The Navy's new plasma compression fusion device, however, claims as its key feature the same principle as in Salvatore Pais' other inventions: the “controlled motion of electrically charged matter via accelerated vibration and/or accelerated spin subjected to smooth yet rapid acceleration transients, in order to generate extremely high energy/high intensity electromagnetic fields.†Pais cites some of his prior publications as evidence that this type of spinning, vibrating electromagnetic system can create the high magnetic fields required to contain powerful fusion reaction in a stable form.
The patent describes how those magnetic fields are generated within a hollow plasma chamber which includes one or more opposing pairs of conical or domed “counter-spinning dynamic fusors†that feature an electrically charged outer surface containing ducts that inject fuel gases, such as Deuterium or Deuterium-Xenon, into the plasma chamber. As these electrically-charged fusors spin, Pais claims, they “create a concentrated magnetic energy flux and electromagnetic radiation within the vacuum chamber,†compressing and heating the gasses within. These fusors vibrate at a high rate as they spin thanks to piezoelectric films such as lead zirconate titanate (PZT) - the same piezoelectric metamaterial Pais claims enables his room-temperature superconductor patent....
