Craft Using an Inertial Mass Reduction Device (US Navy Patent)

Thanks to John Oman for the following comment:

I ‘think’ it is very much related where some of the LENR theories are headed.

From the background section: If we can engineer the structure of the local quantum vacuum state, we can engineer the fabric of our reality at the most fundamental level (thus affecting a physical system’s inertial and gravitational properties). This realization would greatly advance the fields of aerospace propulsion and power generation.

Abstract

A craft using an inertial mass reduction device comprises of an inner resonant cavity wall, an outer resonant cavity, and microwave emitters. The electrically charged outer resonant cavity wall and the electrically insulated inner resonant cavity wall form a resonant cavity. The microwave emitters create high frequency electromagnetic waves throughout the resonant cavity causing the resonant cavity to vibrate in an accelerated mode and create a local polarized vacuum outside the outer resonant cavity wall.

The patent has been granted and “may be manufactured and used by or for the Government of the United States of America for governmental purposes without payment of any royalties thereon or therefor.”
