The Nassikas Lorentz force thruster fails the helium test

Test set up for the helium test

This is a follow up to an earlier posting on the Nassikas thruster.

In August we carried out a helium test on version II and III of the Nassikas thruster at SuperPower Corp. in Schenectady, NY.  We fixed the coil in a liquid helium dewar with its axis pointed in a horizontal direction.  The dewar in turn was suspended from a ceiling beam so that it could move from side to side.  Any side deflection of the dewar, due to any internally developed force, would have been measured on an electronic scale which was in mechanical contact with the wall of the dewar.  The scale would have been able to register a force as small as 20 grams (0.7 ounce). However, the coil showed no evidence of axial thrust even when the current to it was increased to 175 amps.  So we have concluded that this invention is impractical.  This does not apply to version I, which instead uses a conical YBCO casting with an attached permanent magnet.  That version still has potential application.

In my opinion, the reason why the test failed has to do with a flaw in physical theory.  Conventional thinking is that due to the self interaction of its magnetic field and current a coil develops Lorentz forces which try to expand the coil diameter.  But physicists have ignored that there is another force which can strain coils and cause them to expand which is called the Ampere force.  Both forces increase according to the square of coil current.  The difference is that the Ampere force causes a longitudinal tension, along the length of the wire, whereas the Lorentz force would cause a transverse force, perpendicular to the coil windings.  If the Lorentz force were the predominant force causing tension in a coil, we should have seen an axial propulsion in our experiment.  Since our experiment showed no force, we must conclude that the Lorentz force is essentially absent as a self acting force in coils and that instead the coil expanding force is due to the Ampere force.  Since the Ampere force acts along the length of the coil windings, an axial force component would be unable to develop in a conically shaped coil.  So I believe that all we have accomplished with this experiment is to point out a flaw in physical theory.  The reason why our Finite Element Analysis simulations showed that an axial force should have been developed is because that program assumed that coils develop Lorentz forces when energized.  If physical theory was correct, we should have seen a propulsion, just as the simulations showed.  But Nature does not always behave as we might think or like.

    thanks for the update, please let your public know whether a theoretical explanation for the failure of the latest trials should emerge.

      I gave a theoretical explanation in the posting. Namely, that the force is due to the Ampere force and not to the Lorentz force. Our experiment seems to prove this.

    Dr LaViolette, thanks for sharing this valuable information as well for the efforts in this type of research. May I ask whether there are plans for further development of Version I ? I believe the use of tape multilayer superconductors introduced in Version II and III may have introduced further effects or phenomena which eventually led to a suppression of the effect.

      The matter is now in the hands of Dr. Nassikas to decide how he wants to proceed. The version I thruster needs repair before testing can continue. There is more to do on his first version to improve the amount of the thrust. I will help him if he needs further help, but there are no plans in the works right now.
