Theory
From EM Drive
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
- this deserves an entire subsection
- MiHsC, Mike McCulloch
- Harold White's Warp effects
8/5/14 - Greg Egan modeled the resonant modes of a conical cavity.
2/2/15 - @areo modeled evanescent waves using MEEP. Conclusion was that, due to rapid dropoff at the frustum surface, these were of insufficient magnitude to explain the thrust.
