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.

Field Resonance Propulsion
Postulates magnetic/gravity interactions.

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

FuturePropulsion
An anti-gravity device configured as a dome-topped disk.

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.

Gravitational / Universal Engineering
Scientific and mathematical modeling of physics including, gravity, space, anti-gravity, dark matter, solution to the n-body problem, expansion rate of the universe and black holes, which suggests the development of field propulsion for advanced space flight.

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.

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