Richard Banduric presents a detailed model for field-effect propulsion that forms the basis of experimental work he is performing for DARPA in the area of Relativistic Electrodynamics and Exotic Propulsion. Banduric also showcases experimental test apparatus devised as a method for testing this physical model.
Banduric is developing the next generation of propellant-less propulsion devices based on the interaction of the electric fields from charged isolated elements in relative motion. Electric field intensities change when they are viewed from different inertial frames of references due to the effect of Lorentz contraction of the electric charges.
In this presentation, Banduric discusses the reformulation of James Maxwell’s original complex-quaternion to create a propellant-less propulsion concept. Today’s electromagnetic vector equations are based on the Gibbs-Heaviside reformulation of James Maxwell’s original complex-quaternion equations. The reformulation of James Maxwell’s original equations was done by Joshua Gibbs and Oliver Heaviside to remove the “extra terms” from James Maxwell’s original complex-quaternion formulation.

![Propellantless Propulsion Lab Walkthrough | Charles Buhler | Exodus 2024
NASA physicist Dr. Charles Buhler does an impromptu electrostatics lab walkthrough and describes the evolution of Exodus propellantless propulsion drives.
Dr. Charles Buhler is the co-founder of Exodus Propulsion Technology and lead scientist and co-founder of NASA’s Electrostatics and Surface Physics Laboratory at Kennedy Space Center. Dr. Buhler has a PhD in Condensed Matter Physics from Florida State University, which he received in 2000 while working on high temperature superconductors at the National High Magnetic Field Laboratory.
Dr. Buhler has experience working with electrostatic discharge & ESD safety for the Space Shuttle Program, the International Space Station Program and the Hubble Space Telescope Program. He was also a Co-Investigator for three NASA Research Announcements funded by the Mars Exploration Program, and is currently working on NASAs Dust Project focused on utilizing electrostatic methods to remove dust from personnel and equipment that will be sent to the Moon through NASAs Constellation Program.
Dr. Buhler joins us today to discuss his independent research into field-effect propulsion systems at Exodus Technologies, leading to a patented new propulsion technology that requires no fuel or ejection-mass to produce thrust.
