Heidi reported on her collaborations with Jim Woodward and working in his lab this past summer to build a device to demonstrate Mach effects and their use for propulsion.

Heidi-mach_026Heidi reviewed the origins of inertia and in particular how gravity accounts for inertial reaction forces, what Woodward has referred to as Mach effects deriving from Mach's principle of general relativity.

Heidi reviewed the theory behind Jim's experiment designed to produce small amounts of "propellantless" thrust using Mach-effect mass fluctuations produced by an alternating electric field in high voltage capacitors in conjunction with an externally induced alternating magnetic flux in their dielectric cores of the capacitors. Heidi also described the small effects of the sort expected they have detected.

Heidi will be presenting her work with Jim at a special NASA-Air Force Research workshop at the U. S. Space and Rocket Center in Huntsville, Alabama this coming November. One of the main goals of the workshop is to provide a forum for discussing future space propulsion and power concepts and technologies.
