| 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. |
