Magnets at 60 Tesla field strength will enable testing of gravitational field propulsion.
The so-called "hyperdrive" concept won the 2005 American Institute of Aeronautics & Astronautics award for the best nuclear and future flight paper.
The basic concept is this: according to the paper's authors - Jochem Häuser, a physicist and professor of computer science at the University of Applied Sciences in Salzgitter and Walter Dröscher, a retired Austrian patent officer - if you put a huge rotating ring above a superconducting coil and pump enough current through the coil, the resulting large magnetic field will "reduce the gravitational pull on the ring to the point where it floats free".
The origins of this "repulsive anti-gravity force" and the hyperdrive it might power lie in the work of German scientist Burkhard Heim, who - as part of his attempts to reconcile quantum mechanics and Einstein's general theory of relativity - formulated a theoretical six-dimensioned universe by bolting on two new sub-dimensions to Einstein's generally-accepted four (three space, one time).
Dröscher teamed up with Häuser to produce the award-winning "Guidelines For a Space Propulsion Device Based on Heim's Quantum Theory."
Dröscher and Häuser's proposed practical experiment to prove their theory requires "a magnetic coil several metres in diameter capable of sustaining an enormous current density" - something which the majority of engineers say is "not feasible with existing materials and technology".*
So, Mars in three hours? As NS puts it: "Dröscher is hazy about the details", but "suggests that a spacecraft fitted with a coil and ring could be propelled into a multidimensional hyperspace" where "the constants of nature could be different, and even the speed of light could be several times faster than we experience". Then, he says, a quick three-hour jaunt to Mars would indeed be on the cards.
Big 60 Tesla superconducting magnets appear to be becoming feasible. Small 60 Tesla superconducting magnets soon, which would be enough to test the theory. The superconducing magnets also need to have higher current densities. Scaling up the magnets would involve making longer lengths of superconducting wire and more work and research is needed to increase the current density.
The 2005 version of the propulsion papers suggests that 30 Tesla magnets are a starting point for tests.
A transition into parallel space requires a magnetic induction of some 30 T and torus material different from hydrogen. The number of turns of the magnetic coil is denoted by n, the magnetic induction is given in Tesla, and the current through the coil is 100 A, except for the last row where 250 A were used. The mass of the rotating torus is 100 kg, its thickness, d (diameter) 0.05 m, and its circumferential speed is 10^3 m/s. The wire cross section is 1 mm2. The meaning of the probability amplitude is given in the text. For instance, if a larger spacecraft of 10^5 kg with a rotating ring of 10^3 kg needs to have a constant acceleration of 1g, a magnetic induction 0H of some 13 T is needed together with a current density of 100 A/mm2 and a coil of 4×10^5 turns for a value N wgpe=4.4×10−5 . The resulting force would be 10^6 N. Thus a launch of such a spacecraft from the surface of the earth seems to be technically feasible.

Current space transportation systems are based on the principle of momentum conservation of classical physics. Therefore, all space vehicles need some kind of fuel for operation. The basic physics underlying this propulsion principle severely limits the specific impulse and/or available thrust. Launch capabilities from the surface of the Earth require huge amounts of fuel. Hence, space flight, as envisaged by von Braun in the early 50s of the last century, will not be possible using this concept. Only if novel physical principles are found can these limits be overcome. Gravitational field propulsion is based on the generation of gravitational fields by man made devices. In other words, gravity fields should be experimentally controllable. At present, it is believed that there are four fundamental interactions in physics: strong (nuclei), weak (radioactive decay), electromagnetic and gravitational. As experience has shown for the last six decades, none of these physical interactions is suitable as a basis for novel space propulsion. None of the advanced physical theories, like string theory or quantum gravity, go beyond the four known interactions. On the contrary, recent results from causal dynamical triangulation simulations indicate that wormholes in spacetime do not seem to exist, and thus even this type of exotic space travel may well be impossible. However, recently, novel physical concepts were presented that might lead to advanced space propulsion technology, based on two novel fundamental force fields. These forces are represented by two additional long range gravitational-like force fields that would be both attractive and repulsive, resulting from interaction of gravity with electromagnetism. A propulsion technology, based on these novel long range fields, would be working without propellant. The current theoretical and experimental concepts pertaining to the novel physics of these gravity-like fields are discussed together with recent gravitomagnetic experiments performed at ARC Seibersdorf (2008). The theoretical concepts of Extended Heim Theory, EHT, are employed for the explanation of these experiments.
