The craft is totally reactionless and produces thrust by expulsion of virtual mass - extra mass produced when matter "fuses" with energy. A classic example is when mass acquires kinetic energy by accelerating. And by the theory of relativity, we can say that energy has a corresponding equivalence in mass and vice-versa. At the the speed of light, the kinetic energy becomes infinite and mass becomes infinite.
It does this by creating a very strong non-static energy field around the craft. The the non-static energy field increases in intensity by resonating with the Linear accelerators.
The energy field is generated by the LINAC (Linear Accelerator) by sending out electrons, charging the upper hull momentarily at 10 million volts. Once both the lower and upper is fully charged, the two hulls is discharged. The current flows through the plasma inductor and the hull reverses in polarity and then discharged again. This cycle produces a low-frequency, very-high energy electromagnetic waves. The LINAC is then switched to time at the right moment to resonate with the frequency generated to either increase energy or to compensate the lost energy to the surroundings. By resonating with the frequency, the craft can generate very high energy non-static electromagnetic fields while using only a low-power generator so a thermoelectric generator can be used for this purpose.
The non-static energy field in the form of electricity is stored and released by a plasma inductor coil. With such high energy involved, only plasma can be used. This coil functions much like an ordinary inductor.
By wrapping the craft with a high-energy field, any matter that is immersed within this field will gain extra mass or inertia.
Now that we have acquired the "virtual mass" by immersing the spinning barium titanate discs in the energy field, how are we going to expel the mass? Since the discs are spinning, when a part of the disc enter the energy field, it acquires mass so the centrifugal force is stronger in that region. When the part leaves the energy field, it becomes light again and expels the mass. If you look in the diagram above, the interior of the craft is neutral and has no energy field. It is due to the fact that electric charges can only remain on the surface of a conductor. So it is clear that the centrifugal force in the upper part of the disc is higher than the force below so a net upward thrust is produced. Controlling thrust and direction is simple, you just have to adjust the rpm of the individual discs.
THE DIAGRAM BELOW IS A REPLICABLE VERSION OF THE INTERSTELLAR CRAFT. JUST EASY ENOUGH TO BE BUILT BY ANYONE WITH A FIGHTING SPIRIT AND COURAGE TO VENTURE INTO THE UNKNOWN.
