Ion Wind Propelled Star Trek Enterprise

ion wind

[Steven Dufresne] recently demonstrated ion propulsion using high voltage, and someone pointed out it kind of looked like the warp drives on the Star Trek Enterprise… so he went out and bought a model Enterprise and rebuilt his demonstration!

His original video on Ion Winds gives a good summary of the beginning of his experiments. In fact, it’s actually a recreation of a design he saw at the International Symposium on New Energy back in 1996 of the Electrokinetic Apparatus which was patented in 1960.

By creating a high voltage arc of electricity, it appears that the resulting “ion wind” propels the Enterprise with respect to the fixed testing apparatus. Did we mention he made the high voltage power supply himself?

[Steven] also points out that the propulsion might be occurring due to dielectrophoresis, but hasn’t discovered any conclusive evidence to prove that. Even the patent is rather vague on how this works:

The invention utilizes a heretofore unknown electrokinetic phenomenon which I have discovered; namely, that when a pair of electrodes of appropriate form are held in a certain fixed spaced relation to each other and immersed in a dielectric medium and then oppositely charged to an appropriate degree, a force is produced tending to move the pair of electrodes through the medium.

Regardless of how or why it works, it’s a fun video to watch, so make sure you stick around after the break to see it!

    Sounds like…

    I remember obsessing over ion drives as a kid after reading The Hunt for Red October and playing Subwar 2050.

  4. IcYhAwK says:

    Thats too cool. I wonder how much force is being exerted?

  5. T.I.E. Fighter would be more appropriate, wouldn’t it? :D

      Yeah, it definitely is an ionocraft. In fact, I’m working on an explanatory video now that explains it as such. I think James got the idea for it possibly being dielectrophoresis from some related experimenting on my website where I immersed a similar device in mineral oil.

    Dear patent gods,
    Please do not grant this patent based on the extremely vague details provided. No one ever should use the word “unknown” in a patent filing.

    Tax payers, consumers, and the world.

    • Blue Footed Booby says:

      Yeah, I rolled my eyes at that. I mean, there’s an argument to be made that if you’ve invented a device that works then it should be patentable, but I think that if you can’t describe how it works then you can’t possibly have a patent that’s well defined enough to allow a court to tell what is and isn’t infringing.

  8. The advent of piezoelectric transformers makes these feasible at long last.

    The big problem with running these off a flyback is the weight, whereas a PZT series stack powered inductively with diodes to add the peak voltages allows a 10g assembly to generate >20g of thrust.

    I got as far as building a prototype but ran into issues with insulation which in retrospect would have been a matter of silicone encapsulation of just the HV outputs.
    The best sort to use here is the grey car stuff for making gaskets, this is the correct sort that doesen’t outgas acetic acid and has a breakdown in the 10KV/mm range.

    • NotMe says:

      For insulation maybe Polyimid (Kapton HN) foil. Around 0.125mm and >200kV/mm. Is known not to deteriorate in high voltage.

    • StevenD says:

      I hadn’t looked into piezoelectric transformers before. Looking now though… For a power source for my lifter type ionocraft I once did some quick calculations for a 10F/2.5V supercapacitor (1/2CV^2 = 31.25J). From my voltage and current measurements I showed in this video for my lifter 26,000V x 0.000275A for hover = 7.15W = 7.15J/s. So a supercapacitor could theoretically be used as a power source for at least a few seconds of flight. Mind you, the weight is still far too high. A bigger lifter would of course have higher current requirements.

    J.L.Naudin made first successful experiments with this tech 12 years ago:

    He even made his pet mouse fly:

    • It’s sad that this (perfectly valid) “ion wind” effect has been interpreted by the free-energy/antigravity/UFO crowd as something “special” or beyond normal explanation. I groaned when I saw the link to JL Naudin’s site, since he is well into the whole area of cold-fusion/plasma electrolysis etc. I hope that having a link to his site on HaD doesn’t make people think this gives him credibility ;-)

      • RC says:

        It’s unfortunate that the ufo crowd has taken the technology and interpreted it as anti-gravity, which it’s not. It’s electrostatic in nature. However it is significantly more advanced than conventional aerospace propulsion technology in that it’s solid state propulsion not based on the expulsion of matter.

        As for Naudin, he’s performed a number of rigorous and detailed experiments on lifters and as far as that subject is concerned he deserves credibility.

    That was pretty cool thanks Steve and HaD for putting it up

  12. Whatnot says:

    There have been space probes launched that used an ion engine, but the thrust of those things is very low so it’s for probes that have all the time in the world to get up to speed.

    Biefeld–Brown effect
