He is listed in &#039;&#039;[[The Worldwide List of Dissident Scientists]]&#039;&#039;.<br /> <br /> ==Background==<br /> Palfreyman graduated in physics from the University of Oxford in 1970 and subsequently worked in electronics engineering. He has taken an interest in a range of unconventional propulsion ideas, from the work of John Searl (the Searl Effect Generator) to Mach&#039;s-principle-based propulsion.<br /> <br /> ==Work==<br /> Palfreyman collaborated with James Woodward and Paul March on the development of the Mach-Lorentz thruster (MLT), an electromagnetic device intended to produce net thrust by inducing transient fluctuations in the mass of dielectric material in charged capacitors, in accordance with Woodward&#039;s interpretation of Mach&#039;s principle. Results of &quot;Mach-2MHz&quot; experiments were reported in a STAIF-2006 paper co-authored with Paul March, and the concept was described in the paper &quot;Mach-Lorentz Thruster Spacecraft Applications&quot; (AIP Conference Proceedings, 2007). Claims of reactionless or Mach-effect thrust remain outside the accepted physics consensus and are regarded skeptically by the broader scientific community.<br /> <br /> ==External links==<br /> * [https://ui.adsabs.harvard.edu/abs/2007AIPC..880.1063M/abstract &quot;Mach-Lorentz Thruster Spacecraft Applications&quot; (NASA ADS)]<br /> <br /> [[Category:Scientist|Palfreyman Andrew]]<br /> [[Category:Worldwide List of Dissident Scientists]]</div>
