Field Resonance Propulsion - - Postulates magnetic/gravity interactions.

Gravitational Propulsion Research Group - - Yahoo group for research and theory in alternative science,gravitational propulsion, and time study.

Gyroscopes As Propulsion Devices - - Gyroscope based technology could provide an alternative form of propulsion.

Quasi Moto: Theoretical Propulsion Physics - - Considers unconventional means of space propulsion (and any ancillary systems), with the aim to determine their feasibility or basis in fact.

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.
