Introducing the Nassikas Superconducting Thruster, Version III

Here we announce for the first time a new version of the Nassikas superconducting thruster which we believe will produce fantastic results at liquid helium temperatures.  But to make this happen, we need your help; see below.


Key Steps in the Development and Testing of the Nassikas Thruster


Before describing this new thruster design, it is important to state that we think that we now understand why the October liquid nitrogen test of the version II thruster produced a null result.  For background on this thruster and its potential capabilities, visit our crowd funding page: https://www.indiegogo.com/projects/superconducting-levitation-thruster#/.  Before performing the October test, we had the expectation that the thruster would produce a fairly large force.  This was based on computer simulations that one company had performed for us last year.  These overly optimistic results had predicted that a coil with a 3° winding inclination should generate a thrust of 66 kg, and that a coil with an 8° winding inclination should produce a force of about 170 kg.  When we did not see the expected force during our test, we were very dismayed and puzzled.

But now, the reason for the poor results seems clear. During the first half of this year, Dr. Nassikas and others carried out a series of computer simulations on his second superconducting thruster design and got results very different from those that had been done two years ago.  These new simulations indicate that that the coil’s axial force should have been about 10,000 times less than what we thought it would be.  They indicate that, at liquid nitrogen temperatures, the Nassikas thruster II coil with an 8° winding inclination should generate a force of no more than 30 grams, provided that the coil had been properly wound.  However since our coil was wound in such a manner that its windings did not have a consistent inclination, we estimate that the generated force was much less, perhaps no more than 10 to 15 grams, or in other words less than half an ounce.  This would explain the null result of our October liquid nitrogen test.  Random forces from currents in the liquid nitrogen bath would have pushed on the coil with more force than what the coil would have been generating, thus erasing any remaining evidence of an axial force.

The new simulation results also indicate that the version 2 thruster should generate a force of only about 3 kg (30 Newtons) at liquid helium temperatures.  Such a force acting on a 50 kg dewar could be seen in a pendulum test (as a 3° angle of the pendulum), but certainly not enough to get a rig off the ground.

At this point Dr. Nassikas began considering ways of boosting the coil’s magnetic field strength in order to get it to produce more Lorentz force thrust.  He then hit on the idea of adding a superconductive shield layer beneath the coil’s REBCO windings.  Recent studies have shown that by repelling the coil’s magnetic field lines such shield layers modify the field strength in the vicinity of the coil windings in such a way as to dramatically increase the coil’s Lorentz force.  Computer simulations on this coil design, which we call Nassikas thruster version III, indicate that at liquid helium temperatures it should be capable of generating a force of 185 kg (1800 Newtons)!  This force certainly could certainly lift a 50 kg dewar off the ground.

So we plan to have the Nassikas thruster II coil rewound to transform it into the version III design.  We begin with a superconducting shield made from 10 winding layers of REBCO tape.  This winding will be passive (unpowered).  It serves only as a magnetic field reflector.  Over this we will wind the 50 layers of our powered REBCO tape, and the coil should be ready to test; see schematic below.

Our goal is to conduct the liquid helium test this August, i.e., in 5 weeks, but to do that we need to raise $11,000 to pay for the test.  At this point we are needing donations from the public to help out.  Those interested in donating $6,000 or more will receive a percentage of the future income stream coming from the version 2 thruster patent.  Those interested in donating $2000 or more will be given the opportunity to view in person a test of the thruster.  Those wishing to donate please write to me: ethericgate  gmail.com.  Those wanting to send donations via PayPal, send to the starcode (at) aol.com account.  Although keep in mind they deduct an amount for their service.

    Any news on the experiment Dr Laviolette? We are very eager and happy to hear from you.

    • Paul LaViolette says:

      The experiment will be done this month. But we have agreed among us that we should not make the results publicly available until we are prepared to. So have patience. Eventually all will learn how the experiment turned out.

  2. Pascal Leger says:

    Dear Mr. LaViolette, Thank you for your dedication to this research and for acting in such an open-source fashion. I understand your Nassikas Magnetic Thruster V III is proceeding. Wish your team success here. In regards to your future needs for investments, do you have documents that would present time table and funds needed to reach an actual working prototype, let’s say to power a small vehicle? Pascal.

  3. Dr. LaViolette,

    Great to hear tests are moving along. Will these tests be available for viewing this month? I am interested to see the results.

    • Paul LaViolette says:

      No, not this month. Can’t predict exactly when we will upload the results since there will be a period of studying the results and analyzing the data, regardless of whether the results turn out positive or negative.

  4. Thomas says:

    Hello Mr. Laviolette,

    In your Crowdfunding-Video https://www.youtube.com/watch?v=zTLkZ0jms3s for the Nassikas-Thruster (which will produce no thrust imo) at 4:25 a “thruster” is shown that oscillates off center. If there is resp. was a thrust, why then is it ocillating? It should swing to the side and STAY off-center and not swing. Explanation???

    • Paul LaViolette says:

      I have already answered this question in the comments to the Nassikas postings. I suggest reading the comments to find your answer. The swinging is an expected result.

  5. Dr. Paul, good to hear of your progress up the learning curve. Will continue to refer people to you and your effort

  6. Panos Sketos says:

    If you use the same coil for economy. With the same imperfect structure.

  7. Fred Koch says:

    You made my day when I read this. I remember a guy who replied to my post on another forum about the Mk II. He sent me a link to a youtube video which described a thruster with superconducting material used as a shield. I am concerned with this thruster having to use liquid helium. Will there be any new high temperature superconducting materials tested with the thruster? And finally, how much does this version weigh? Crossing fingers and impatiently waiting for the results! Best of luck to you both! Regards, Fred Koch

    • Paul LaViolette says:

      Liquid helium is not a big issue for space travel. NASA uses it in their missions to cool detectors in space. Cryogenic coolers have progressively dropped in weight. So liquid helium should not be a problem. No new materials. We use the same tape we used before. Currently we know of no other high temperature superconductors that are commercially available other than the one we are using. In 10 years maybe we will be able to buy room temperature superconductors, who knows. The coil weighs about 5 kilos without its dewar.

      • Fred Koch says:

        I was more concerned with liquid helium being used here on the plamet. I was hoping this technology would be available for public consumption.

        • Paul LaViolette says:

          Maybe when room temperature superconductors are developed, there will be no need for liquid helium.

          • Fred Koch says:

            Why was liquid nitrogen used if it really needed liquid helium?

          • Paul LaViolette says:

            Look, I think I explained this in the posting. We expected the thruster to develop a large measurable thrust at liquid nitrogen temperatures. So obviously it would be the first test to do. The liquid helium test costs about $8500 more. Which is why it was a less reasonable option at that time.

  8. Jimmie Raye says:

    Is there another Go-Fund Me campaign put up yet?

    • Paul LaViolette says:

      No, we decided not to repeat the Indiegogo campaign because of lack of time. We need to do this test at the beginning of next month, August.
