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
- Mike McCulloch's MiHsC[1] - this deserves an entire subsection - see http://physicsfromtheedge.blogspot.co.uk/
- Harold White's Warp effects
- Evanescent waves[2]
- Transfer of linear momentum from the Quantum Vacuum to magnetoelectric and chiral molecules [3]
8/5/14 - Greg Egan modeled the resonant modes of a conical cavity.
