Theory of a Mach Effect Thruster

The Mach Effect Thruster [1, 2, 3, 4] (MET) is a device which uses Mach’s principle in Einstein’s General Relativity to produce a constant acceleration in a device which is undergoing internal energy changes and mass fluctuations. Mach’s principle is a statement that the inertia of a body is the result of the gravitational interaction of the body with the rest of the mass-energy in the universe. The MET device requires no fuel as a propellant needing only electric power of 100-200 Watts to operate. The thrusts at the present time are smallon the order of a few micro-Newtons. The first part of the paper is devoted to experiment and a description of the MET device and apparatus for measuring thrusts. In the second half of the paper, we re-introduce the idea of advanced waves, by summarizing Dirac, Wheeler-Feynman and Hoyle-Narlikar (HN). We show how Woodward’s mass fluctuation formula can be derived from first principles using the HN-theory which is a fully Machian version of Einstein’s relativity. HN-theory reduces to Einstein’s field equations in the limit of smooth fluid distribution of matter and a simple coordinate transformation.
