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)
  • Conservation of momentum breaking theories
  • Harold White's Warp effects
  • Evanescent waves[2]


8/5/14 - Greg Egan modeled the resonant modes of a conical cavity.
