Stellarotor / Centrifugal Pulsatory - A little theory (omniradiation, gravitation, centrifugation as effects of it, dynamic mirrors, ...) and some models as direct derivatives from mechanical vibrators, crank-conn.rod-slider mechanism, eccentric mathematics.
Theory for Gravitic Propulsion - A theoretical discussion of using gravity as a means of interstellar space propulsion. Touches on the theories of matter, energy, and space time.
Unproven Space Concepts - A collection of works aimed at the conquest of space. Including laws on motion, energy and time plus a design for an interstellar spacecraft.
