This book include novel methods for distributing spacecraft fuel. Accordingly, we consider the following. Staged Electron Gas Compression Guns With Emphasis On Electron Plasma Modes For Facilitating Nuclear Fueling Of Remote Relativistic Spacecraft Propelled By A Diverse Mix Of Propulsion Mechanisms. The book is divided into two main portions, each of which is self-contained in its presentation. However, each part provides notable differences in content although conceptually, there is a lot of material common to both parts. The author recommends reading of both portions to obtain the benefit of the overall broader presentation of the systems thus proposed. In this book, the reader will be presented with content affirming that velocities arbitrarily close to the speed of light may be obtained using nuclear fusion fuel as an energy source for spacecraft propulsion. Ironically, such virtual light-speed travel may be accomplished without large spacecraft mass-ratios where spacecraft are remotely fueled from external sources.
