    Improbable Thruster Seems to Work by Violating Known Laws of Physics

    Every action creates an equal and opposite reaction. It’s perhaps the best known law of physics, and Guido Fetta thinks he’s found a way around it.

    According to classical physics, in order for something—like a spaceship—to move, conservation of momentum requires that it has to exert a force on something else. A person in roller skates, for example, pushes off against a wall; a rocket accelerates upward by propelling high-velocity combusted fuel downward. In practice, this means that space vessels like satellites and space stations have to carry up to half their weight in propellant just to stay in orbit. That bulks up their cost and reduces their useful lifetime.

    With that in mind, Fetta designed what he called the “Cannae Drive,” which he claims creates momentum without pushing against seemingly anything at all. He recently convinced a team at NASA to test it, who presented the results at a conference yesterday.

    Design
    BACKGROUND

    The Cannae Drive proof-of-concept (POC) superconducting resonating cavity is an experimental prototype designed to demonstrate the principle of unbalanced force generation. The POC cavity, experimental configuration, experimental method, and experimental results of the Cannae Drive POC tests are described in this section of the website.

    On Jan 13, 14, and 17, 2011, the Cannae Drive POC experiment successfully demonstrated linear unbalanced force generation in a series of tests conducted at Niowave Inc. located in Lansing, MI. Niowave also built the POC cavity and the experimental apparatus.

    Inventor Guido Fetta has developed a 2nd technology that develops thrust without the use of on-board reaction mass. This new technology uses RF interactions with a dielectrically loaded waveguide to produce thrust. This new technology functions by a mechanism that is different from the Cannae Drive thrust mechanism. Cannae LLC has patent pending status on a wide range of designs based on this new technology.

      that's just an assymetric capacitor
      The pure in heart will see the light.

        Maybe, Not the optimal geometry for an asymmetric capacitor.


        It seems their own theory of operation is incorrect.

        Anomalous Thrust Production from an RF Test Device Measured on a Low-Thrust Torsion Pendulum - NASA Technical Reports Server (NTRS)

        This paper describes the eight-day August 2013 test campaign designed to investigate and demonstrate viability of using classical magnetoplasmadynamics to obtain a propulsive momentum transfer via the quantum vacuum virtual plasma. This paper will not address the physics of the quantum vacuum plasma thruster, but instead will describe the test integration, test operations, and the results obtained from the test campaign. Approximately 30-50 micro-Newtons of thrust were recorded from an electric propulsion test article consisting primarily of a radio frequency (RF) resonant cavity excited at approximately 935 megahertz. Testing was performed on a low-thrust torsion pendulum that is capable of detecting force at a single-digit micronewton level, within a stainless steel vacuum chamber with the door closed but at ambient atmospheric pressure. Several different test configurations were used, including two different test articles as well as a reversal of the test article orientation. In addition, the test article was replaced by an RF load to verify that the force was not being generated by effects not associated with the test article. The two test articles were designed by Cannae LLC of Doylestown, Pennsylvania. The torsion pendulum was designed, built, and operated by Eagleworks Laboratories at the NASA Johnson Space Center of Houston, Texas. Approximately six days of test integration were required, followed by two days of test operations, during which, technical issues were discovered and resolved. Integration of the two test articles and their supporting equipment was performed in an iterative fashion between the test bench and the vacuum chamber. In other words, the test article was tested on the bench, then moved to the chamber, then moved back as needed to resolve issues. Manual frequency control was required throughout the test. Thrust was observed on both test articles, even though one of the test articles was designed with the expectation that it would not produce thrust. Specifically, one test article contained internal physical modifications that were designed to produce thrust, while the other did not (with the latter being referred to as the "null" test article). Test data gathered includes torsion pendulum displacement measurements which are used to calculate generated force, still imagery in the visible spectrum to document the physical configuration, still imagery in the infrared spectrum to characterize the thermal environment, and video imagery. Post-test data includes static and animated graphics produced during RF resonant cavity characterization using the COMSOL Multiphysics® software application. Excerpts from all of the above are included and discussed in this paper. Lessons learned from test integration and operations include identification of the need to replace manual control of the resonant cavity target frequency with an automated frequency control capability. Future test plans include the development of an automatic frequency control circuit. Test results indicate that the RF resonant cavity thruster design, which is unique as an electric propulsion device, is producing a force that is not attributable to any classical electromagnetic phenomenon and therefore is potentially demonstrating an interaction with the quantum vacuum virtual plasma. Future test plans include independent verification and validation at other test facilities.
