The Challenges of Developing the Technology for A Realistic Starship Propulsor

Can we describe a typical field propulsion device considering that so many different and contradictory theories exist? Minter and Chiao (2007) performed an analysis predicting the location of the maximum electric field due to a charged ring. Results using direct current suggest that the ring could not stably levitate. A transient field and a third field created by magnetic currents may yield contrary results. This ring can be a primary component for a spacecraft drive generating an azimuthal magnetic field at some distance above a bank of asymmetric capacitors. These capacitors generate a radial electric field. The propulsor uses these subsequent interacting fields to create a Poynting cross-product that is additive to the Lorentz force generating propulsive levitating motion. These McCandlish-like devices essentially take advantage of interactions between two very strong electromagnetic fields. Moreover, the technology to develop such an electromagnetic dipole-like spacecraft propulsor is currently available; however, a major problem is finding a suitable portable power generation system. Another field propulsion notion includes a Searl-like device that may satisfy some available photographic data. Here, the device components act as electromagnetic dipoles or separate homopolar generators that may create a relativistic repulsive gravitational field also using a Poynting vector to generate levitation. Furthermore, the circular motion of these dipoles and charges could create an electromagnetic vortex, which if conditions are permitted, could induce a gravitational vortex using Gertsenshtein’s principle. This is an area of aerophysics that needs additional investigation. Nomenclature
