Title: Innovations of James Wayne Purvis

Introduction

James Wayne Purvis is a notable inventor based in Albuquerque, NM (US). He holds a total of 8 patents that showcase his contributions to the field of propulsion systems for spacecraft. His innovative designs reflect a deep understanding of electrodynamics and the principles of propulsion.

Latest Patents

One of his latest inventions is the Pulsed e-field propulsion system. This system discloses an electric field propulsion mechanism for spacecraft, which includes a capacitor stack comprising an array of supercapacitors. Solid-state electronic circuits generate modulated currents and electric fields in pulse coils. The pulse coils direct the electric fields onto separated electric charges stored in the capacitor stack. The resulting unidirectional Lorentz Forces generate thrust without the need for reaction mass. Reaction momentum is carried away by Poynting Vector fields, adhering to the principles of electrodynamics. Notably, the design is scalable down to micro-chip sized thrusters.

Another significant invention is the Segmented current magnetic field propulsion system. This system outlines methods for electromagnetic field spacecraft propulsion. It includes reaction thrust assemblies comprising conductor coils with alternating segments of magnetic field shield assemblies. Unshielded reaction thrust assembly segments are bracketed by field activation coils that generate shaped magnetic fields. The action of the magnetic fields on currents in the unshielded coil segments produces unidirectional Lorentz Forces, generating thrust without reaction mass, while reaction momentum is again carried away by Poynting Vector fields.
