NASA Veteran Behind Propellantless Propulsion Drive Announces Major Discovery (thedebrief.org) 259

Longtime Slashdot reader garyisabusyguy shares a report from The Debrief: Dr. Charles Buhler, a NASA engineer and the co-founder of Exodus Propulsion Technologies, has revealed that his company's propellantless propulsion drive, which appears to defy the known laws of physics, has produced enough thrust to counteract Earth's gravity. "The most important message to convey to the public is that a major discovery occurred," Buhler told The Debrief. "This discovery of a New Force is fundamental in that electric fields alone can generate a sustainable force onto an object and allow center-of-mass translation of said object without expelling mass." "There are rules that include conservation of energy, but if done correctly, one can generate forces unlike anything humankind has done before," Buhler added. "It will be this force that we will use to propel objects for the next 1,000 years until the next thing comes."

To document his team's discovery as well as the process behind their work, which Dr. Buhler cautions is in no way affiliated with NASA or the U.S. Government, the outwardly amiable researcher presented his findings at a recent Alternative Propulsion Energy Conference (APEC). Filled with both highly-credentialed career engineers and propulsion hobbyists, APEC is an organization The Debrief once referred to as the World's Most Exclusive (And Strange) Anti-Gravity Club. In conjunction with that presentation, "The Discovery of Propellantless Propulsion: The Direct Conversion of Electrical Energy into Physical Thrust," Dr. Buhler also sat down with APEC co-founder and moderator Tim Ventura to explain how his past in electrostatics, which is his primary area of expertise, ended up being a key component of his discovery of this new force. [...]

Up next, Buhler says his team is seeking funding to test their devices in space to better understand the force at work. "We're hoping to do some demos," said Buhler. "Some space demos. That's what we're trying to get some funding to do. I think that would be a great way to show off the technology." Besides proving once and for all that the force they are seeing is real, the accomplished engineer believes that such tests could encourage other scientists to search for an explanation of what exactly it is they are seeing. "I think it's a good opportunity for people to run these tests, look at them, watch them go in space, watch it move in space, and then say, "what does it imply? What are the implications?'" Until that time, Buhler says he believes his work proves that the force they are seeing is "fundamental" and that understanding it is the next logical step. "You can't deny this," he told Ventura. "There's not a lot to this. You're just charging up Teflon, copper tape, and foam, and you have this thrust."

So, while his team believes their experiments speak for themselves, the veteran scientist says he also believes it is the job of science to analyze and understand this discovery. If successful, he thinks it may even address some of the harder questions in science, including the nature of dark energy or even space/time itself. "It's easy to make these things," he said, "so it's a tool for the scientific community to use to try to explore those hard questions."
If there are companies or individuals interested in working with Exodus Propulsion Technologies, Buhler asks that they reach out via their LinkedIn page.

    he could easily demonstrate and experiment with it on the ground. So why ask for investment to go to Space? The cold fusion guys at least published stuff and let the community debunk it instead of asking for investments. I don't say the 4 letter s-word.
    • Exactly what bothered me. If they can counter gravity on earth with "1g" of thrust, they can amaze everyone tomorrow by a public demonstration with journalists, scientists and all and they'd have billions of investor money instantly. So something smells like fish oil here.
      • TFA says that only the part that actually does the magic can generate 1g of thrust but adding stuff to it like landing gear, gyroscopes, control fins, etc would be too much.

        I don't know why he cares about generating 1g of trust on earth's surface anyway. Generating a tiny fracton of that in space over a long period of time is fantastic, if he could really do it, which, well, we all remember the EmDrive, which they sent up to space last year but never actually managed to test somehow, but which has recieved

        I propose calling this sort of thing an N3 drive, in recognition of the fact that what the various inventors are really claiming is a means of bypassing Newton's third law.

        Nice to see that TFA follows the common science-reporting practice of telling you next to nothing about how this new breakthrough is supposed to work while going on at length about its myriad benefits.

      There isn't much to push off in space. It seems fairly obvious to me. Taking it to space rules out a whole slew of Earth related forces that skeptics would assert this is using in some manner such as the Earth's magnetic field and so on.

      Of course given that there is a giant interconnected mess of gravitational pulls throughout our solar system and the galaxy I've always wondered that nobody seemed to be looking at pushing/pulling on them in a more serious way than old school newtonian senses.

        Because that doesn't exist. People are already making the most of what the unintuitive ends of Newtonion physics has to offer, using gravitational slingshots, the Oberth effect, Hohmann transfers and so on. There isn't really anything else left.

        • Does your sig actually say more about you than about perpetual motion machines?

          • It does: my sig has nothing to say about perpetual motion machines. They don't exist, I assume everyone knows this.

            I think the mental gymnastics people (particularly angel'o'sphere) employ to avoid understanding that an EM drive is equivalent to a perpetual motion machine is funny. That is indeed saying something about me.

      • Agreed and this point is exactly my problem with one statement in the article:

        "The magnitude [10 mN] is not important, really, since anything above zero would work in space!"

        Actually it is important because it's easy to get fooled by external influences when the effect is tiny. If he was measuring 50 N of force it's easy to eliminate subtle testing artifacts, e.g., interactions with Earth's magnetic field. So in this case either scaling up to larger forces or getting into space seem like the only options.

    This part of the article jumped out at me (without propellant!)

    Another unusual result from their tests was that sometimes the tested devices did not require a constant input of electrical charge to maintain their thrust. Given that the device already appears to violate the known laws of physics by creating thrust without propellant, this result even stumped Dr. Buhler and his team.

    “We can see some of these things sit on a scale for days, and if they still have charge in them, they are still producing thrust,” he told Ventura. “It’s very hard to reconcile, from a scientific point of view because it does seem to violate a lot of energy laws that we have.”

    That really doesn't make sense...unless the device is interacting with its test chamber. Then it's in a simple static (electric) equilibrium, [wikipedia.org] an electric field pulling it toward part of the test chamber.

    Violating conservation of energy should be an indication that something is wrong. Unfortunately, I think this is something all emissionless drives do, if you point two opposite each other and tie them together. If they don't emit anything, the energy going into them is vanishing.

    The conservation laws are statistical, at least to a degree. Local apparent violations can be OK, provided the system as a whole absolutely complies.

    There's no question that if the claim was as appears that the conservation laws would be violated system-wide, which is a big no-no.

    So we need to look for alternative explanations.

  • This would be great news, if true. But you can prove this without going to space. Hang it on a cable, like a pendulum. Turn it on. If the cable is no longer vertical, you have thrust.

    Can't do that? Then it doesn't work. Simple and cheap to test.

    • by gweihir ( 88907 )

      Not quite. You can verify it does not work that way, but if it works, it may well be something else than actual thrust.

    • actually it's a kid's science experiment to do just that by hanging a properly shaped spike from a metal wire and applying EMF, ionized air provides thrust with these kind of "lifters", also can be done as a ion wind rotor. No unknown physics are at work, been done since 18th century 8D

    All you have to do is show me that you can have something pop up of its own accord and Get tugged out of a power Jack because it's thrust is so powerfully that it loses its power once the plug is pulled.

    Do that in front of a bunch of reporters and VCR will be begging you to accept their money.

    This sounds fishy because he won't even do a half-cooked demo that shows thrust in a lab environment.

This is clearly another case of too many mad scientists, and not enough hunchbacks.
