Salvatore Pais

of the type Pais undertook during his doctoral research. Source: NASA Pais was born in Romania in 1967 and emigrated to the United States at approximately age thirteen. Pais received his Ph.D. in mechanical and aerospace engineering from Case Western Reserve in 1999. His doctoral advisors were Yasuhiro Kamotani and Simon Ostrach, both of whom had conducted Spacelab experiments in microgravity conditions aboard the Space Shuttle mission STS-50 in 1992. Pais's doctoral research was sponsored by NASA. ==Career==

Pais has presented at American Institute of Aeronautics and Astronautics conferences over the years. Transfers within the defense establishment In June 2019, Pais left NAWCAD and transferred to the U.S. Navy's Strategic Systems Programs (SSP), the organization responsible for the development and sustainment of the Navy's submarine-launched ballistic missiles. In January 2021, he transferred to the United States Air Force. As of 2025, Pais works for the United States Space Force and is reportedly based in Bonn, Germany. ==Patents==

reduction device. The patent was initially rejected, but was granted after James Sheehy, the Naval Aviation Enterprise's chief technology officer, wrote to the United States Patent and Trademark Office asserting that the invention was operable and warning that the Chinese military were developing similar technology. This patent expired on January 9, 2023, due to non-payment of maintenance fees. • Piezoelectricity-induced room temperature superconductor (filed 2017, published February 21, 2019): A device purportedly capable of achieving superconductivity at room temperature, which would enable "the transmission of electrical power with no losses." The Institution of Engineering and Technology noted that no evidence was presented to demonstrate that the device worked, and that the highest-temperature superconductors achieved at that time operated at approximately −70 °C (−94 °F). The claim was also covered by Phys.org. The superconductor patent application led to appeals by the U.S. Navy and Pais, after being initially rejected by the U.S. Patent Office. • Plasma compression fusion device (filed 2018, published September 26, 2019): A compact nuclear fusion reactor described as capable of producing power in the gigawatt to terawatt range. Popular Mechanics described it as a "compact nuclear fusion reactor" whose "designs seemingly stretch the limits of science." The concept was also described in a peer-reviewed paper published in IEEE Transactions on Plasma Science in 2019. The patent application was ultimately abandoned. ==The "Pais Effect" and Navy testing==

Central to all of Pais's inventions is a theoretical concept he calls the "Pais Effect," which he describes as the generation of extremely high electromagnetic energy fluxes through the controlled motion of electrically charged matter subjected to accelerated vibration and/or accelerated spin. Pais said those experiments had not yet produced the 1 Coulomb charge he considered necessary for the Pais Effect to work. Internal documents obtained through Freedom of Information Act requests by The Drive revealed that the project had been considered to have "National Security importance" within NAWCAD, and that research notes referenced a "Spacetime Modification Weapon" that could theoretically dwarf the power of a hydrogen bomb. In the 2025 interview summarized by Interesting Engineering, Pais rejected suggestions that his patents were disinformation, saying they were "not a bluff" and asserting that the underlying physics was correct. Several of Pais's patents, including the electromagnetic field generator and the high-frequency gravitational wave generator, have since expired due to non-payment of maintenance fees, and the plasma compression fusion device patent application was abandoned, suggesting that neither Pais nor the Navy is actively pursuing these technologies through the patent system. According to The Times, "mainstream publications still refuse to publish him". ==Selected publications==

Pais lives in California. He described himself as religious. Pais was noted for having virtually no web presence. The Times reported that Pais stated in his capacity as a private individual that he believes extraterrestrial life exists, may possess technologies similar to his inventions, and are a form of "superintelligence" that "considers the human race 'an experiment'." ==See also==
