In the short version of their 2007 paper, Advanced Propulsion Systems from Artificial Gravitational Fields 89 , Dröscher and Hauser dropped their fermion coupling approach and discussed how they would reconfigure Tajmar’s apparatus to become GME2 (Gravito Magnetic Experiment #2), a “bench test” experiment employing boson coupling through a spinning superconductor ring with some key differences. This apparatus would have two advantages.

First, their proposed addition of a solenoid coil and rotating superconductor above it would allow a gravity-like field to be produced through rotation at a constant angular velocity. This is incontrast to Tajmar’s GME1 which had only shown evidence of a gravity-like field during periods of angular acceleration. Second, their novel arrangement of components would produce a gravity-like field with a force parallel to its axis of rotation – optimal for providing thrust against earth’s gravitational pull. This configuration should maximize an axially propulsive force through the device capable of countering earth’s pull. If sufficiently strong it should lift off the ground.

In their original proposal employing fermion coupling Dröscher & Hauser predicted that the strength of the gravity-like field could be multiplied relatively easily giving a propulsive force equal to earth’s gravitational pull and perhaps even 2, 3 or 4 times greater. In devising GME2 they believed that their redesign employing boson coupling could achieve results at least as great as those of fermion coupling and serve as the basis for a field propulsion principle.

Over several of their papers Dröscher and Hauser have suggested that the design of GME2 would consist of a superconducting solenoid coil providing an imaginary induction field in the z (up) direction over the rotating disk. It requires that the coil be a different material than the superconductor and that the z-component of the gravitophoton field acting upon a large mass is responsible for the gravitational field above the disk.

One of the more interesting aspects of this configuration is that it generates a secondary azimuthal (circumferential) torque that acts to rotate the disk. Therefore less energy is required to keep the angular velocity of the disk constant. So in addition to providing a gravity-like field for propulsion, the configuration in question rotates the disk without use of any additional motors or mechanisms.

For the smaller generator shown on the home page the size of a tea saucer employs a spinning superconducting disk of material Md within a coil of 10 turns composed of superconducting material Mc. A current of 8 amperes is applied and the disk is spun at a rotational speed of 50 meters/second (~6,400 rpm). Such a configuration should be able to produce a gravity-like field (Fz) 0.3% of earth’s gravitational field (mg).

A similar configuration mentioned in their 2010 paper to the AIAA specifies that a 0.015 g field (1.5% g) could be produced using:
• A solenoid 0.2m in diameter

• 50 turns of the coil

• Supplied with about 10 amperes of current

• A rotational speed of the disk of 50 m/s (angular velocity = 105 radians/second)
