This page will outline some candidate theories of operation (or non-operation).

Debunking Theories

  • These theories should be explained, then debunked with the simplest explanation, with a link to a dedicated page to show the work or work in progress that backs up that explanation.

Experimental error

  • It's all a hoax/conspiracy
  • Simple measuring error
  • Thermal effects
  • Mechanical vibration
  • Magnetic effects with environment

These are discussed in more detail at Possible Error Sources.

Proponent Theories

  • Guido Fetta's, Cannae Drive creator's Theory
  • Roger Shawyer's, EM Drive creator's theory
  • Quantum foam MHD
  • Harold White's Quantum vacuum plasma thruster (QVP thruster)
  • Harold White's Warp effects
  • Evanescent waves[1]
  • Transfer of linear momentum from the Quantum Vacuum to magnetoelectric and chiral molecules [2]
  • @notsosureofit Hypothesis
  • Mike McCulloch's MiHsC Theory
  • Curving Rf beams[3] - The magnitude of the bending needed, was not shown by the thermal camera images taken at Eagleworks.

8/5/14 - Greg Egan obtained an exact solution for the resonant modes (having azimuthal quantum number m=0, constant electromagnetic field variation in the azimuthal direction) of a cavity in the shape of a truncated cone with spherical ends. Greg Egan calculated the forces and showed a proof that the net force is zero and therefore that there is no thrust force in a resonant electromagnetic cavity of any arbitrary shape, and for any arbitrary mode shape, when the cavity is analyzed according to the standing wave solution of Maxwell's equations.
