Progress on the GEM (Gravity-Electro-Magnetism) Theory of Field Unification and its Application to Human Flight
Progress on the GEM ( Gravity-Electro-Magnetism) theory is presented and its application to human flight. The GEM theory is an alloy of Kaluza-Klein and Sahkarov approaches to unification postulates that that the separate appearances of gravity and EM as long range forces from the Planck scale is correlated with the separate appearances of the proton and electron from a particle-antiparticle pair. Both separations are postulated as stemming from the appearance of a new compactified Kaluza-Klein fifth dimension. The physical length associated with the new fifth dimension is found to be a classical particle radius. The requirement that this GEM scheme be in accord with the Standard Model requires that the fifth dimension be an image of a spacetime interval with a timelike part giving birth to the electron and the spacelike portion having three subdimensions corresponding to the quarks making up the proton. The requirement of cosmic charge neutrality and equal classical radius leads to the requirement of e=qx+qy+qz and e2 = qx2+qy2+qz2 where qx, qy,and qz are the charges of the quarks and is satisfied by the choice 2e/3 =qx, qy, -e/3=qz and this is found to be preserved in a SO(3) symmetry group. In Human flight applications, the Vacuum Bernoulii Equation is found to result from the ExB drift model of gravity in the GEM and to suggest that powerful rotating EM fields may be used to modify gravity.

An overview of the VASIMR engine: High power space propulsion with RF plasma generation and heating
The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is a high power, radio frequency-driven magnetoplasma rocket, capable of exhaust modulation at constant power. While the plasma is produced by a helicon discharge, the bulk of the energy is added in a separate downstream stage by ion cyclotron resonance heating (ICRH). Axial momentum is obtained by the adiabatic expansion of the plasma in a magnetic nozzle. Exhaust variation in the VASIMR is primarily achieved by the selective partitioning of the RF power to the helicon and ICRH systems, with the proper adjustment of the propellant flow. However, other complementary techniques are also being studied. Operational and performance considerations favor the light gases. The physics and engineering of this device have been under study since the late 1970s. A NASA-led, research effort, involving several terms in the United States, continues to explore the scientific and technological foundations of this concept. The research involves theory, experiment, engineering design, mission analysis, and technology development. Experimentally, high density, stable plasma discharges have been generated in Helium, Hydrogen and Deuterium, as well as mixtures of these gases. Key issues involve the optimization of the helicon discharge for high-density operation and the efficient coupling of ICRH to the plasma, prior to acceleration by the magnetic nozzle. Theoretically, the dynamics of the magnetized plasma are being studied from kinetic and fluid perspectives. Plasma acceleration by the magnetic nozzle and subsequent detachment has been demonstrated in numerical simulations. These results are presently undergoing experimental verification. A brisk technology development effort for space-qualified, compact, solid-state RF equipment, and high temperature superconducting magnets is under way in support of this project. A conceptual point design for an early space demonstrator on the International Space Station has been defined. Also, a parametric study of a fast (115 day,) VASIMR-driven human Mars mission has been completed. This paper reviews the progress obtained in all these areas and outlines plans and strategies for continued research. © 2001 American Institute of Physics.
