> The concept is fairly simple, although the engineering required to make it a reality is anything but. All matter contains energy on the quantum level. By theoretically creating its own incredibly dense and polarized energy field, the hybrid craft is claimed to be able to create a quantum 'vacuum' around itself which allows it to repel any air or water molecules with which it interacts.

As a PhD in physics, this just sounds like nonsense to me. Energy isn't a field and to polarize it doesn't mean anything.

> Little information can be found about Salvatore Cezar Pais; he has virtually no web presence. What is known is that he received a PhD in Mechanical and Aerospace Engineering from Case Western Reserve University in 1999 and that he currently works as an aerospace engineer for NAWCAD at Naval Air Station Patuxent River in Maryland – the Navy’s top aircraft test base. Pais has published several articles and presented papers at American Institute of Aeronautics and Astronautics conferences over the years describing his work in electromagnetic propulsion, revolutionary room temperature superconductors, and topics like his PhD dissertation: "Bubble generation under reduced gravity conditions for both co-flow and cross-flow configurations."

My sample size is small at ~5, but former classmates who joined the military research labs were not the brightest bunch. Of my overall cohort, the smartest ones went into industry, sometimes a different industry than their field of study. The smart but idealistic ones went into academia. And then the ones that truly never shed their sophomoric arrogance, acquired in their formative years and that should have been beaten out of them by the doctoral process, went to the military labs to work on secret stuff.

It may have been true in the past, but military labs don't have the cachet to attract top talent.

With that being said, the most likely reason for this patent filing, as others have noted, is misdirection.
