Craft using an inertial mass reduction device
Salvatore Cezar Pais · US Department of Navy
In one minute
Salvatore Pais’s Navy patent, filed in 2016 and granted in 2018, describes a proposed craft built around a resonant cavity: a charged outer wall, an insulated inner wall, a gas-filled gap and microwave emitters. The document says that rapidly accelerating vibration and axial rotation of the charged surface would polarize the nearby vacuum. Pais links that proposed polarization to negative pressure, reduced inertia and motion through air, water or space. The background section estimates field-energy fluxes from a spinning charged disk, then from accelerating vibration, and cites Schwinger’s pair-production threshold. The description proposes a 300 MHz to 300 GHz microwave-emitter range and material-dependent cavity Q factors. The filing sets out an apparatus and its asserted operating mechanism; it does not report a constructed craft, thrust measurement, or inertial-mass-reduction measurement.
Connection
This Navy patent states Pais’s proposed charged-surface, vibration and rotation mechanism with apparatus details and parameters. It is a source for studying the proposal, not evidence that a craft’s inertia was reduced.
From the source
In its background, Pais proposes that artificially generated high-energy electromagnetic fields would interact strongly with the vacuum energy state and increase the energy density attributed to vacuum particles; the patent reports no measurement of that interaction.Background
Pais proposes that coupling accelerated vibration with axial rotation of a charged surface could polarise the local vacuum and reduce inertial and gravitational mass; the patent reports no mass-reduction measurement.Background
The patent proposes that a polarised local vacuum would exert negative pressure and reduce resistance to motion. It reports no craft test of that effect.Background
For a specified charged disc, the patent estimates energy fluxes of 10²⁴ W/m² from rotation, 10²⁴–10²⁸ W/m² with vibration, and about 10³³ W/m² in a separate accelerated-vibration example. It predicts pair production and full vacuum polarisation; these are calculations and claims, not measured outputs.Background, Equations 1–4
The proposed craft uses inner and outer resonant cavity walls with a noble-gas gap (xenon is given as an example) and microwave emitters in the 300 MHz–300 GHz range. The description assigns a material-dependent cavity Q-factor of 10⁴ to 10⁹; it does not report a built cavity measurement.Description; claims 1–4
Pais envisions a hybrid aerospace/undersea craft moving through air, space and water inside a proposed vacuum-plasma sheath, with directional control by vibrating selected shroud sections. The patent reports no flight or underwater test.Description, FIG. 2
