This doppler shift inside the EM drive proves Yuri Ivanov's Rythmodynamics to be solidly correct. He was the first to discover this compression of waves when a body is in motion or when 2 freqs with a small shift causes motion of the body relative to space. Em drive is nothing more than yuri ivanova discovery in a well thought out simple application. Solution to this doppler effect inside the em drive? Simple. Dont use a fixed frequency magnetron, but rather a variable frequency. Which is needed once the body begins motion. Or even more precise control, Use 2 magnetrons with different frequencies, to setup the constant force. This would allow it to remain intact even though it's in motion relative to ambient space. Again, right back to Yuri Ivanov's discovery. The whole concept is based on his discovery.
Anistropic black bodies will radiate more infrared photons from the warmer side. Infrared imaging confirmed that one end of the device was warmer than the other. This means the device is a photon thruster that relies on the anisotropy of the surface temperature from one end to the other. Note that this effect turned up on the Voyager spacecraft, which veered off their planned trajectories due to this very effect.
Finally I have a clear explanation of what the EmDrive was. Whenever I googled it I couldn't comprehend what I was reading. The visual aids in the parts 1 and 2 of "An Explanation of the EmDrive" really helped me understand the concept now.
AsteronX I'm currently working on a macro ion driven plane the issue it finding a small enough air frame to take the tiny capacitor and discharge rod these guys must be seriously nerdy I'm bad enough 😂
There is an intuitive explanation to come up with this design. Zero point energy is known to compress two plates when they come closer than some 1 micrometer. There is less radiation pressure between the plates than outside the plates. This due to canceling out of certain frequencies due to the size of the oscillation chamber. The forces cancel each other out and so there is no force left for propulsion. If somehow the surface of one plate could be bigger than the other and the pressure would remain the same, a remaining force would result, and the plates could start slowly moving. This fragile notion could lead to experiments with cone shaped containers.
Wouldn't the size of both plates by definition be identical as the effect can only occur between the plates? Also the size of the plates in the EmDrive seems to be identical anyways, because the smaller (front) side of the resonant cavity would combine with the component of the angeled sides that is on the plane perpendicular to the thrust direction. Also, why is there less radiation pressure in the resonant cavity? It seems to me that there is _more_ radiation pressure as there are microwaves trapped inside the cavity.
If the only thing that this drive produced was heat, you could get a small amount of thrust from the big end plate sublimating more than the small end. That would not be a reaction-less drive. I do hope that it's more than that, or some other material loss, though.
I love this channel, hope you guys continue making many more videos!! I dont know if you're taking any suggestions, but it'll be so awesome to see an explanation of how certain metamaterials make things invisible
Thank you for the suggestion and feedback. We will consider it. For the moment, there is much work to be done. Have a look at our new website, AsteronX.com. It is not yet complete, but it will give you some idea of how busy we are [our plans].
I'm not ready to throw out conservation of momentum just yet. Confirmation bias and sloppy accounting of error sources in experiments are the things that are keeping the EM-Drive alive. This video talks as if the EM-Drive is a proven thing. It definitely is not.
From what I grasp the momentum is dependent on the volume of the cavity not the area of the thrust end so if this is scaled up to a much larger size than these experimental models the gain in thrust should be substantial since volume is cubed but the emitting area is only squared.
I'm curious about the energy factors at work in this device. If I understand what I heard in these videos, all of the research says that thrust coming out of the device increases as power coming into the device increases. I wonder if these scientists are dealing with something akin to what those working with the fusion reactor are dealing with … that is … it costs more in energy going in to generate a vastly smaller amount of energy going out. I could well be comparing apples to oranges but not being an electronic engineer or a physicist, I'm just unsure. Of course, I'm unsure about a lot of things so if this is not the case, I would be inclined to believe that one day, an appreciable amount of thrust can be generated with a minimal energy input to the device generating the thrust. I would be interested in hearing YOUR comments.
At the moment the scientists working on the project agrees that the drive is generating a thrust. How it is generating a thrust is up for hot debate. The thrust effect does increase in proportion to an increase in power. Until we expand our understanding - accept what the data is showing us, no one will be able to design a more efficient drive, which could reveal additional critical data.
Good to see the principles of the EMdrive and the Cannae drive which will be brought together in the new Willnae drive developed at the Haggis Fields test centre on the Isle of Barra.
Why not use light waves or lasers in an optical cavity which would be similar to a microwave cavity? They are both electromagnetic waves differing only in wavelength or frequency. This could allow for miniaturization and higher output thrusts as e=hf e-energy h= planck constant and f= frequency.
I am glad to see other educated people watch these "hokey" videos. My Ph.D.s are in Astrophysics and Electrochemistry, and I concur with Warthog and Isodoublet - any experiment that is unrepeatable is invalid - period. In addition, it is quite obvious that both understand the engineering concepts of the various types of errors that can manifest themselves in experiments. My question is this - why put out all that money for a "milli-Newton per kilowatt" experiment unless the eventual gain can be stated in kilo- (or mega-) Newtons per kilowatt ? That sounds like a government "boondoggle" or money-pit experiment to me...
Those three theories are incorrect. The EMdrive supports resonant modes of microwave radiation composed of massless photons. This resonant system is massive. An individual photon is massless but the system of counterpropagating photons in the cavity is massive. That's very important to understand that a system of massless particles confined to a region is massive as a whole. Now what we have going on here is a massive time varying system. These are the conditions necessary for gravitational induction to take place. Small ripples in spacetime that propagate out as waves; gravitational waves. The shape of the cavity sets up a partially standing wave in the cavity from the superposition of the counterpropagating waves traveling end to end. The time evolution of the partial standing wave (and remember that this wave is massive) creates a marching jerking (change in acceleration) motion of the wave in one direction only. The overall shape of the EMdrive is an octupole. A the contents therein constitute a massive time varying octupole. A gravitationally radiating octupole radiates preferentially in one direction, anisotropic radiation vice isotropic radiation. A gravitational wave rocket.
Is there a specific publication that you could refer to or other equations demonstrating that the photons within the resonant cavity gain mass and/or behave as if they are massive?
AsteronX yes you can look at it from two different ways and get the same answer. Photons in a box: usersguidetotheuniverse.com/index.php/2013/03/31/i-get-mail-does-a-box-of-photons-have-mass/ And the mass of a system of counterpropagating photons. en.m.wikipedia.org/wiki/Invariant_mass Separately, looking at a a different system, but using the same concept, is that most of your mass is from binding of massless gluons within your neutrons and protons. Each individual gluon is massless but massive as a confined system.
onehit pick I'm pretty sure that the superposition of two counterpropagating electromagnetic waves of different amplitudes induces an a changing acceleration in the sum, and that changing acceleration produces a changing gravitational field (a nonconservative and changing gravitational field...induced fields are nonconservative meaning they act as an external force field that can change the total mechanical energy of the system) acting on a massive particle (which is also being influenced by the ambient conservative gravitational field) would serve to have a net effect of reducing the inertia of that massive particle depending on its path. I do understand how weak this must be so I'm trying to understand how to make it stronger. Some of my more recent posts on NSF have acknowledged the fact of how weak these gravitational effects are, so I've focused back on the problem of conservation of momentum using plain old classical mechanics, while keeping the gravitational ideas on the back burner, in hopes of finding a consistent concept. So I acknowledge that I'm wrong too, and I'm at least on the right track.
15:41 well, I am trying to propell my drone with this but my knowledge is extremely low and I just know that I can't make anything until and unless I learn some more thrust
I think it is just the momentum exchange due to photons leaving the cavity. Interaction with the fabric of space doesn't make sense. The extra thrust compared to a pure photon engine is maybe due to some un-wanted interactions in the experiment.
If we see the case of refraction of light through glass, it seems that a very small , probably a tiny black hole, is present on the surface of glass, whose force of attraction is more than the force of attraction of sun, which diverted a light particle through a very very small angle, as observed by Eddindons experiment during total solar eclipse in the year 1919.So the partical which is diverting the p hotone from its path during refraction through glass must have force of attraction more than sun. Also during photo electric emission it has been proved that a p hotone is a particle having some mass.
What happens if we substitute micro waves for sound waves within the cavity, and would the variation of wave speed effectbthe overal end game. I say this as a non sciencetist type who being involved with sound have felt the effect of low rage soundwaves. For it to effect the boby, which it does, there has got to be an outgoing energy. I ask this based on the knowledge that it says in the begining there was nothiing, then a sound which started the whole ball rolling. Sound is more easy to control and to change even in the smallest of measurements. I would also be interested in the idea of changing the cavity to being made of ceramics of some kind. Just a thought?????
Thinking in terms of a wave...wouldn't parallel surfaces create a slapback effect that creates problems? Intuitively it seems that geometry may be a chief component to solving problems with thrust. Somehow creating an exponential increase in amplitude until releasing it out of the chamber perhaps.
Ok, now to start with I'm studying biology (veterinary medicine, not physics), but I AM a Sci-Fi geek. IF this or a variant could be scaled up to provide some significant thrust (even .01G) to a crewed size craft then it would be worthwhile for extended space exploration, it might even shave some time off a trip to Mars. It seems as if a realistic experiment would be something like the Cannae drive people want to do, use a micro-sat with (I'm guessing) solar panels for power. Then feed that power to the drive and see if it moves.
The Chinese have retracted their assertion that they measured significant thrust. I reviewed the NASA paper and they did not build the power source into their device, meaning that they were supplying energy and momentum from outside source. This invalidates the experiment. They also did not account for ionic flow from the device. It's probably just an ion drive, with ion charge being supplied from outside current. They've made a very inefficient cathode that has asymmetric electron boiling.
Oh, and the NASA paper is: White, Harold; March, Paul; Lawrence, James; Vera, Jerry; Sylvester, Andre; Brady, Davi; Bailey, Paul (17 November 2016). "Measurement of Impulsive Thrust from a Closed Radio-Frequency Cavity in Vacuum" (PDF). Journal of Propulsion and Power: 1-12. doi:10.2514/1.B36120. In which they state up front the first (among many) of items that completely invalidates the experiment: "All dc power and control signals pass between the external equipment and vacuum chamber internal components via sealed feedthrough ports." It is a very amateur error to supply power to a sensitive thrust test from outside the craft unless you are trying to demonstrate remote sourced thrust applications (like fire-hose drive).
Says the armchair physicist. Your so much smarter than Chinese scientist. They should have just sent you the device. We might already have made it to a different Galaxy. Publish your TH-cam thoughts.
Skepticism is healthy, but skepticism in the face of mulitple experiments showing positive thrust.. this is crossing into climate denial tactics. and frankly, I don't consider the word of some random dude on the internet to be sufficient to 'invalidate' anything. this is the internet, and misinformation spreads as fast or faster than information. I'll wait for more experiments before I decide on the technology.
As an architect, not an engineer or math whiz, my intuition says a simple cone shaped chamber is probably just a first step. I'm thinking a more parabolic shape might hold promise.
I love how military applications and defense regarding the technology’s military applications are already being brought up. . . I really hope we have a plan to deal with this technology, because reactionless drives would allow RKMs to be pretty easy to build. A full working EMdrive which is actually very simple tech would basically mean that anyone with the knowhow, (a terrorist, an enthusiastic school kid, etc.) will have access to weapons that make the death star look like a wet firecracker in regards to the real world.
As with any technological advancement, it make certain things easier. For example, the gun over the bow & arrow. Nonetheless, we will learn to work with them.
The most likely Gilo application would be to lift an ultralight wing on the flying car not the car its self but even that would require the high Q super conductor version. Lifting the wing to the right height is the challenge with para-foil cars. Poles have been used, and small integrated balloons or drones are in the works. The Emdrive would be a order of magnitude below those at best. Regardless of how the emdrive works I would still want wings so we have a fail safe glide ratio if the Emdrive stops working.
The first working helicopter rotor lifted 1 tenth of its own weight not including the motor. This all depends on whether the Q factor scales with some parameters and materials. Hence the super conductor work. I'm a sceptical optimist.
I'm a bit surprised people are jazzed about this "drive" when obviously more efficient mechanisms are trivial to imagine and construct (and also powered by electricity rather than conventional thrust). In some ways this seems a bit similar to a much more efficient trust generator that I invented 30 years ago (when I was just a kid).
Thank you for choosing to communicate your thoughts rationally rather than reacting emotionally. My statement is an actual complement to you. Folks are consciously and unconsciously seeking a light at the end of the metaphorical tunnel in an uncertain and changing world. The fact that the EmDrive does produce thrust provides some light. But, it also reminds us that the more we learn, the more we release just how much we really do not know.
One other thought. The working fluid of a jet engine or a propeller driven aircraft is air. The working fluid of the em drive is considered in this video to be space itself. This idea is somewhat hidden by the theoretical details presented but that is what it amounts to. The em drive is a jet engine whose working fluid is space itself.
After learning that the force of gravity is merely the consequence of time dilation (and time dilation is the consequence of the mass or energy density) a tide would be formed in a region where there is a gradient of energy density and therefore a gradient of time dilation. And if a tide is formed a tidal force would be experienced. Normally, an assymetric solid clump of mass will not move along its own tide because... well, the gradient is formed by its own mass and the equivalence principle, in effect the inertial mass is shaped exactly such that a solid object will not self accelerate regardless of how asymmetrically one might shape it. However, given that the photons in the cavity are massless and given the presence of the energy flow between the two plates (assuming the energy is conserved) as the energy flux of those photons traverses from one end to the other a weak (but non zero) energy density gradient, and consequent time dilation gradient is established.... without the inertial mass to go with it. Of course we have the thruster's shell and power source as overhead, but in theory the energy flux we can pump into the volume is arbitrary and only limited by our technology. This gradient would be proportional to the net energy flux, which is proportional to the magnetron power, Q and volume.
It could be great if the emdrive in fact worked. It would also be great if this will help us understand space or matter. In a simple interpretation though, it would be interesting to compare a wattage/time energy loss compared to a mass/acceleration, to see if they can be simply converted.
Presumably the EMDrive and Cannae Drive do not conserve their energy so the question is really only how the RF cavity energy is getting out past the reflective end walls-maybe the 'exponential' exterior waves from '100%' internal reflections do-carry energy not-previously-computed, or, maybe deBroglie waves instead of 'less-efficient' photons... (that'd be #4,5).
How does Unruh radiation assymetrical cavity pilot wave quantum virtual plasma and quantized inertia explain the conservation of momentum in the em drive? And how does the cannae drive works since it's not assymetrical? How could it be an hyperspace warp drive?
To produce 1lb of thrust would take 2.224 Mw So for the little girls EmDrive powered hoverboard she would need 50, 2Mw Cummins DQKAB Diesel Generators at 9 tons each, 450 tons Also a 110 Mw microwave skateboard might require a license
Technology always does more with less. To do what your iPhone does today would have required a huge bank of vacuum tube computers years ago that would have taken as much electricity as a small town.
Thanks for asking. Warp Drive Part II is finally about to be published, and it's 100 times better! Publication E.T.? By or before the end of next week - for sure.
I believe the pulsating, swirling photon is the energy unit of this universe that makes up everything in existence in this universe. Everything in existence are photons and interacting photons. Everything in existence is 'light'. What is called 'gravity' is a part of what is currently recognized as the 'photon'. 'Gravity' would be the force that makes the sine wave of em expand and contract and would act basically 90 degrees to the em forces which of course act basically 90 degrees to each other. Here is a test for the 'gravity' portion of my theory of everything idea. I would do this test myself but do not currently have the necessary resources to do so, but maybe some entity reading this might have the resources, do the test, then tell the world what is found out either way. a. Imagine a 12 hour clock. b. Put a magnetic field across from the 3 to 9 o'clock positions. c. Put an electric field across from the 6 to 12 o'clock positions. (The magnetic field and electric field would be 90 degrees to each other and should be polarized so as to complement each other.) d. Shoot a high powered laser through the center of the clock at 90 degrees to the em fields. e. Do this with the em fields on and off. (The em fields could also be varied in size, strength, density and depth. The intent would be to energy frequency match the laser and em fields for optimal results.) f. Look for any gravitational / anti-gravitational effects. (Including the utilization of ferro-cells so as to be able to actually see the energy field movements.) 'If' effects are noted, 'then' further research could be done. 'If' effects are not noted, 'then' my latest TOE idea is wrong. But still, we would know what 'gravity' was not, which is still something in the scientific world. Science still wins either way and moves forward.
ben rich former head of lockheed skunk works says they found the mistake in the math(what ever that means) and they now have interstellar capabilities anything youve seen on star trek or star wars theyve tried and either made it work or tried something else and now have the ability to take ET home,im sure all the theories in this video would work perfectly if the fabric of space was plaid.
This effect is fully explained in Unified Theory of Everything. It is really gravitational drive, but construction is simple, therefore thrust is small. With knowledges about gravity and gravitational force, we can simple increase thrust 100 times in similar size on about 100mN/kW, similar to best ion thruster. This principle is good for small satellites, not for traveling to deep universe. Therefore we develop fully functional Warp Drive which works on antigravitational annihilation reaction inside gravi-nuclear propulsion. This propulsion can accelerate with 1-4G on lightspeed, and we can be on any of million habitable planet in galaxy in 3 years traveling.
Not much: emdrive.com. In our opinion, the EmDrive is not efficient enough to actually function as a drive--wrong figuration. However, that it not what is interesting. What is interesting is that there is any thrust at all--it may have revealed "something"... more on that in the near future. That said, should Mr Shawyer develop a flying machine, we will make another video about the EmDrive. Thanks for asking.
Good Video. I like your open minded approach unlike some in the so called scientific community! - I dont fully understand the drive. I would like to believe. Still, seeing is believing. If some actually makes a working prototype that accelerates a object then I will be more inclined to believe . I am open minded. We will have to wait and see.
The fact that the drive produces more thrust than a pure photon rocket is what has caught everyones attention... asking themselves, "how is this possible."
Ly:bInhn DhInhm:Ateidr Yes, for this application. All atomic interactions are a result of the electromagnetic force. Electromagnetic Force is fundamental force in nature. Electromagnetic force holds atoms together. This makes nuclear force strongest. Since everything in nature is charged with particles by manipulating the frequency of the magnetism you can achieve a far greater thrust that is infinite since magnetism never decay.
The liquid nitrogen trials produced no discernible thrust (certainly not the levels predicted). The liquid helium trials have been cancelled pending further work.
First scientific publication was in 2002. At first, many scientists viewed it as quackery, but then they realized that something very interesting was taking place, which is why everyone started building & testing them, such as NASA, etc. What is taking place inside the EmDrive reveals something about the universe, in a small way.
Yah just hammer one side of your microwave shorter and off you go. No really, I would be so happy to see this worked. One problem is that if we don't totally understand why something works, like quantum observations for example, they may malfunction under some new external circumstance. I wonder where energy is typically lost in these devices besides supposed conversion to thrust, possibly heat loss?
we live in a wonderful time... things like EmDrives... Quantum Tunneling... Entanglement... is right in our reach... I feel we are close... I think, (hope), that they will be used for space travel more than making people cars float... ;)
We are indeed in interesting times........ and yes, space exploration/travel is the main objective and for really good reasons which we will discuss in a not too distance video. Flying cars will be a natural byproduct.
looking forward to the upcoming video... it will be years before this technology can operate in anything but the vacuum of space though... still, it's totally exciting !!!... :D
Even if the EmDrive works, the thrust would be so miniscule that the claim to fly a car with it is laughable. The only application is for space probes.
Could we be at the point where new laws of physics are to be discovered? Just because something doesn't conform to physics as we currently understand them doesn't mean that it's not possible. This is where we learn the next chapter as we write it.
The microwave towers motion when first started they couldn't explain the towers movement's thinking wind as the causal but scientists wouldn't confirm or deny it had something to do with the same effects.
The only real question is the status of the high Q, doppler compensated version. That is the drive of real interest. The rest is only a tease. Until someone thinks they have the know how to build the third generation and does so we can only wait. Given the third generation the settlement of the solar system will be possible as well as cities suspended in air. Truly a new world.
Similar to the photon compositor a storage and released .if a Transistors of vacuum tubes had frequencies as well they could have discovered it sooner .maybe Tesla had .
dont get why the em drive is getting all the hype. woodward based drives seem to be more intriguing as it starts with theory and then builds a device to exploit theory, rather than trying to prove a magical invention works.
Don't know if you didn't mention this because you're trying to push a narrative for youtube views or because this video is old and you just didn't have the info at the time but it's looking more and more like the thrust being given out is a result of earth's magnetic field interacting with the drive's electronics despite the shielding around the experiment: when the Drisden study opened the experiment chamber and manually rotated the engine rather than rotating the whole chamber, they found that the direction of the thrust did not change as it should have. They then went to formulate a model of magnetic field engine interaction and the math was consistent with the thrust findings. This is the same group in Germany you mentioned in this video. Maybe we'll have hover tech in the future but this engine will not be what powers it.
It makes thrust through convection/pressure difference caused by heat difference of parts of device and remaining gasses - near vacuum in test chamber, could be outgassing/sublimating away part of itself or container, radiant (photon) thurst and magic pixies (hf radiation + sensitive opamps, + current loops through low intensity invisible glow discharges = bad ;-) and human errors ;-) messing with your "über sensitive - i mean it, i wouldn't wonder if it can detect g-changes at solar tides ;-) mechanical force sencors.
So 1.2mN/kw means you need to input 833.33 MW to accelerate 1kg. Put that into perspective, the average car engine weighs up to 2,000kg and puts out about 0.074 MW. Those numbers don't add up to zipping around at speed. The plant required to power this and therefore provide significant thrust will weigh many times more than that, but seeing as the plant is so heavy I'd be amazed if it even twitched. So all this bullshit about "hovering" cars is just that, bullshit. The only place this may be of any use is in space, but given that we already have better, more efficient ways to accelerate bodies in space what's the point?
What is stated in the video: "So, are we really going to have flying cars in our future? I'm sure that before too long-we will have unconventionally propelled flying vehicles, though they may not look anything like what we have come to expect-and, they will most definitely be equipped with artificial intelligence. >>Whether the EmDrive or something like it will be used in these vehicles or not, is too soon to know.
Results from testing have been too inconsistent. Some have measured force in the "wrong" direction. Several have noted no forces at all. To date devices producing thrust have never been observed to produce thrust when mounted on a platform with their power supply, strongly suggesting that thrust may come from interactions with electromagnetic forces by the power cables, with net-zero effects when both ends of the cables are measured. AFAIK this is still in the realm of "needs demonstration of sustained force that accumulates into actual velocity, in a vehicle with onboard power supply, before I believe it."
You postulate that photons flip between being waves and particles? Take a first year quantum mechanics course. Neither classical waves nor particles properly describe behaviour on a quantum scales. The simplest description is that they are a "quantised" burst of waves with a wave function which describes it's position an momentum, really they don't fit into either a wave or particle description. These are only constructed names given in classical mechanics to simplify calculations
Roger Shawyer gives a perfectly sensible and accurate description of how his drive works. The principles are based on standard Einsteinian relativistic physics. People objecting to the explanation just don't understand the basic principles of relativity. No exotic explanations are necessary and that is the true genius of the device. It is so simple that only a real genius would think of it. No laws of physics are being broken here, just do the maths. Roger deserves the Nobel Prize for this and those sceptics who don't understand how to apply the equations of physics are acting shamefully.
You really think anyone who perfects it will willingly release real data for anyone to replicate it. The ones who own this technology will control the future.
Ok. The EM drive tested by NASA measured 1.2 millinewtons per kilowatt. To put that in perspective, our favorite time travel car, the Delorean, uses 1.21 gigawatts. That amount of power is equal to 392.04 foot-lbs of thrust. To put that in perspective, the 3.5L Ecoboost engine from Ford creates 420 foot-lbs. Your videos are fun but aside from conjecture, there isn't much substance.
O yes! It will replace current propulsion system. Energy of "Nothing" is too great... there is only one problem... can energy meter be fastened to the "Nothing".
The colloquial meaning of the term "theory" is the opposite of "fact", it is a guess, or hunch (what a scientist would call a "hypothesis"). But in Science, the meaning of the term "theory" is totally different. Theory and fact can be the same. Atomic Rockets: www.projectrho.com/public_html/rocket/respectscience.php#id--"It's_Just_A_Theory" Fact vs. Theory vs. Hypothesis vs. Law… EXPLAINED!: th-cam.com/video/lqk3TKuGNBA/w-d-xo.html Hypothesis vs. Theory: th-cam.com/video/IzU_ZvzkHdg/w-d-xo.html
The EM Drive presents-illustrates another discovery in science. This is the reason for the videos. Likely by the end of this year we will discuss what that discovery is.
How about building a device that make photons that "cancel" each other out purposely instead of this primitive prototype that seem to be built accidentally and not on purpose to test the theory of that giving the trust?
Radiation pressure can create trust in open waveguide only and is extremely small and useless for driving...15 years ago I have invented real propellantless drive using EM waves but is has small thrust force to power ratio...So I have invented another type propellantless drive which is not using EM waves and has extremely large force to weight ration capable of lifting itself and a large payload...
I am the original designer for this drive. The original concept involves a sharp tapered cone on the end of the cavity. The principle was the photons would undergo many more reflections in the conical section than in the flat region near the microwave input. Since the same photon deposits more momentum in the conical section than in the flat portion causing an asymmetry of momentum in the system where more momentum is deposited on the conical side. This momentum imbalance was hypothesized to cause a force in the direction of the conical section. The theory is sound all we await is someone to demostrare this principle in the lab. Good luck fellow star travellers.
"They will most likely be equipped with artificial intelligence" BUT WHY THOUGH? Its like saying wooden pencils need a vision reactor to work. Just saying seems very unnecessary for driving a hover car.
John Roach nope, just incomplete, newton doesn't has the tools to understand all the fenomena involved on nature, after einstein complete part of newton work, but still a lot of fenomena that are waiting for an explanation.
Its this asalation of phase canslation thing that made me turn away from this whole microwave rattle can idea of pushing a ship a few years ago. But if the Chinese are being forthright, maybe I would consider it useful for a probe or to drop satellites onto orbit for remote sensing and cartography, though I'm still not sold on the idea...
The emdrive motor still requires electricity so it is not perpetual motion, so i don’t see any benefit of such emdrive motor, if we want to make it perpetual , we should hook it up to a magnet motor to supposedly generate invinitive trust.
It is *not* a perpetual motion machine. Within the EM Drive a previously unknown effect is taking place, this is interesting and therefore requires further research.
Already KESHE foundation technology has made flying car, and also KESHE technology students made at least one car, as far as I know. And Iranian government has the KESHE technology.
The best video on EMDrives I have yet seen. There is a little more with the history of proponents & detractors like hard vacuum tests but still the best vid. Monomorphic just put a drive on www.thingiverse.com/thing:2505612 Jim Woodward should get a mention though since he has been working with Mach Effect thrust since about 1992.
This doppler shift inside the EM drive proves Yuri Ivanov's Rythmodynamics to be solidly correct. He was the first to discover this compression of waves when a body is in motion or when 2 freqs with a small shift causes motion of the body relative to space. Em drive is nothing more than yuri ivanova discovery in a well thought out simple application.
Solution to this doppler effect inside the em drive? Simple. Dont use a fixed frequency magnetron, but rather a variable frequency. Which is needed once the body begins motion. Or even more precise control, Use 2 magnetrons with different frequencies, to setup the constant force. This would allow it to remain intact even though it's in motion relative to ambient space. Again, right back to Yuri Ivanov's discovery. The whole concept is based on his discovery.
Anistropic black bodies will radiate more infrared photons from the warmer side.
Infrared imaging confirmed that one end of the device was warmer than the other.
This means the device is a photon thruster that relies on the anisotropy of the surface temperature from one end to the other.
Note that this effect turned up on the Voyager spacecraft, which veered off their planned trajectories due to this very effect.
Finally I have a clear explanation of what the EmDrive was. Whenever I googled it I couldn't comprehend what I was reading. The visual aids in the parts 1 and 2 of "An Explanation of the EmDrive" really helped me understand the concept now.
Our next video will be Warp drive part II
AsteronX I'm currently working on a macro ion driven plane the issue it finding a small enough air frame to take the tiny capacitor and discharge rod these guys must be seriously nerdy I'm bad enough 😂
Can't waiiiiiiiiiiiiiit
Warp Drive? these things you have discussed are clearly on the aint going anywhere list.
There is an intuitive explanation to come up with this design.
Zero point energy is known to compress two plates when they come closer than some 1 micrometer.
There is less radiation pressure between the plates than outside the plates.
This due to canceling out of certain frequencies due to the size of the oscillation chamber.
The forces cancel each other out and so there is no force left for propulsion.
If somehow the surface of one plate could be bigger than the other
and the pressure would remain the same,
a remaining force would result,
and the plates could start slowly moving.
This fragile notion could lead to experiments with cone shaped containers.
Wouldn't the size of both plates by definition be identical as the effect can only occur between the plates? Also the size of the plates in the EmDrive seems to be identical anyways, because the smaller (front) side of the resonant cavity would combine with the component of the angeled sides that is on the plane perpendicular to the thrust direction.
Also, why is there less radiation pressure in the resonant cavity? It seems to me that there is _more_ radiation pressure as there are microwaves trapped inside the cavity.
If the only thing that this drive produced was heat, you could get a small amount of thrust from the big end plate sublimating more than the small end.
That would not be a reaction-less drive.
I do hope that it's more than that, or some other material loss, though.
I love this channel, hope you guys continue making many more videos!! I dont know if you're taking any suggestions, but it'll be so awesome to see an explanation of how certain metamaterials make things invisible
Thank you for the suggestion and feedback. We will consider it. For the moment, there is much work to be done. Have a look at our new website, AsteronX.com. It is not yet complete, but it will give you some idea of how busy we are [our plans].
I'm not ready to throw out conservation of momentum just yet. Confirmation bias and sloppy accounting of error sources in experiments are the things that are keeping the EM-Drive alive. This video talks as if the EM-Drive is a proven thing. It definitely is not.
"Man will never fly!"
From what I grasp the momentum is dependent on the volume of the cavity not the area of the thrust end so if this is scaled up to a much larger size than these experimental models the gain in thrust should be substantial since volume is cubed but the emitting area is only squared.
Perhaps!
I'm curious about the energy factors at work in this device. If I understand what I heard in these videos, all of the research says that thrust coming out of the device increases as power coming into the device increases. I wonder if these scientists are dealing with something akin to what those working with the fusion reactor are dealing with … that is … it costs more in energy going in to generate a vastly smaller amount of energy going out. I could well be comparing apples to oranges but not being an electronic engineer or a physicist, I'm just unsure. Of course, I'm unsure about a lot of things so if this is not the case, I would be inclined to believe that one day, an appreciable amount of thrust can be generated with a minimal energy input to the device generating the thrust. I would be interested in hearing YOUR comments.
At the moment the scientists working on the project agrees that the drive is generating a thrust. How it is generating a thrust is up for hot debate. The thrust effect does increase in proportion to an increase in power. Until we expand our understanding - accept what the data is showing us, no one will be able to design a more efficient drive, which could reveal additional critical data.
Good to see the principles of the EMdrive and the Cannae drive which will be brought together in the new Willnae drive developed at the Haggis Fields test centre on the Isle of Barra.
Why not use light waves or lasers in an optical cavity which would be
similar to a microwave cavity? They are both electromagnetic waves
differing only in wavelength or frequency. This could allow for
miniaturization and higher output thrusts as e=hf e-energy
h= planck constant and f= frequency.
I thought the same, laser gyros are almost an Em Drive
I am glad to see other educated people watch these "hokey" videos. My Ph.D.s are in Astrophysics and Electrochemistry, and I concur with Warthog and Isodoublet - any experiment that is unrepeatable is invalid - period. In addition, it is quite obvious that both understand the engineering concepts of the various types of errors that can manifest themselves in experiments.
My question is this - why put out all that money for a "milli-Newton per kilowatt" experiment unless the eventual gain can be stated in kilo- (or mega-) Newtons per kilowatt ? That sounds like a government "boondoggle" or money-pit experiment to me...
Those three theories are incorrect. The EMdrive supports resonant modes of microwave radiation composed of massless photons. This resonant system is massive. An individual photon is massless but the system of counterpropagating photons in the cavity is massive. That's very important to understand that a system of massless particles confined to a region is massive as a whole. Now what we have going on here is a massive time varying system. These are the conditions necessary for gravitational induction to take place. Small ripples in spacetime that propagate out as waves; gravitational waves. The shape of the cavity sets up a partially standing wave in the cavity from the superposition of the counterpropagating waves traveling end to end. The time evolution of the partial standing wave (and remember that this wave is massive) creates a marching jerking (change in acceleration) motion of the wave in one direction only. The overall shape of the EMdrive is an octupole. A the contents therein constitute a massive time varying octupole. A gravitationally radiating octupole radiates preferentially in one direction, anisotropic radiation vice isotropic radiation. A gravitational wave rocket.
Is there a specific publication that you could refer to or other equations demonstrating that the photons within the resonant cavity gain mass and/or behave as if they are massive?
AsteronX yes you can look at it from two different ways and get the same answer. Photons in a box:
usersguidetotheuniverse.com/index.php/2013/03/31/i-get-mail-does-a-box-of-photons-have-mass/
And the mass of a system of counterpropagating photons.
en.m.wikipedia.org/wiki/Invariant_mass
Separately, looking at a a different system, but using the same concept, is that most of your mass is from binding of massless gluons within your neutrons and protons. Each individual gluon is massless but massive as a confined system.
A box with photons absolutely has additional mass due to the photons. This is just basic E = m c c
Mass is no more than confined energy
And that would generate 1e-97 N of thrust.
onehit pick I'm pretty sure that the superposition of two counterpropagating electromagnetic waves of different amplitudes induces an a changing acceleration in the sum, and that changing acceleration produces a changing gravitational field (a nonconservative and changing gravitational field...induced fields are nonconservative meaning they act as an external force field that can change the total mechanical energy of the system) acting on a massive particle (which is also being influenced by the ambient conservative gravitational field) would serve to have a net effect of reducing the inertia of that massive particle depending on its path. I do understand how weak this must be so I'm trying to understand how to make it stronger. Some of my more recent posts on NSF have acknowledged the fact of how weak these gravitational effects are, so I've focused back on the problem of conservation of momentum using plain old classical mechanics, while keeping the gravitational ideas on the back burner, in hopes of finding a consistent concept. So I acknowledge that I'm wrong too, and I'm at least on the right track.
The vortex spin in side isn't really needed .just as a directly placed refractory would keep resonance straightened.
15:41 well, I am trying to propell my drone with this but my knowledge is extremely low and I just know that I can't make anything until and unless I learn some more thrust
I think it is just the momentum exchange due to photons leaving the cavity. Interaction with the fabric of space doesn't make sense. The extra thrust compared to a pure photon engine is maybe due to some un-wanted interactions in the experiment.
If we see the case of refraction of light through glass, it seems that a very small , probably a tiny black hole, is present on the surface of glass, whose force of attraction is more than the force of attraction of sun, which diverted a light particle through a very very small angle, as observed by Eddindons experiment during total solar eclipse in the year 1919.So the partical which is diverting the p hotone from its path during refraction through glass must have force of attraction more than sun. Also during photo electric emission it has been proved that a p hotone is a particle having some mass.
Reminds me of the "cold" or "room temperature" fusion nonsense a while back. LOL Vaporware comes to mind, here. :)
Cold fusion has been demonstrated a number of times since. It just isnt in the news.
What happens if we substitute micro waves for sound waves within the cavity, and would the variation of wave speed effectbthe overal end game.
I say this as a non sciencetist type who being involved with sound have felt the effect of low rage soundwaves.
For it to effect the boby, which it does, there has got to be an outgoing energy.
I ask this based on the knowledge that it says in the begining there was nothiing, then a sound which started the whole ball rolling.
Sound is more easy to control and to change even in the smallest of measurements.
I would also be interested in the idea of changing the cavity to being made of ceramics of some kind.
Just a thought?????
the only consistency in science is scientists will say something is impossible until it happens then they find the explanation.
They will often also say that they knew it all along.
This is for space thrust, it barely pushes at all, but in space, that's gold! It could accelerate indefinitely in space with barely any fuel cost.
Thinking in terms of a wave...wouldn't parallel surfaces create a slapback effect that creates problems? Intuitively it seems that geometry may be a chief component to solving problems with thrust. Somehow creating an exponential increase in amplitude until releasing it out of the chamber perhaps.
Ok, now to start with I'm studying biology (veterinary medicine, not physics), but I AM a Sci-Fi geek. IF this or a variant could be scaled up to provide some significant thrust (even .01G) to a crewed size craft then it would be worthwhile for extended space exploration, it might even shave some time off a trip to Mars.
It seems as if a realistic experiment would be something like the Cannae drive people want to do, use a micro-sat with (I'm guessing) solar panels for power. Then feed that power to the drive and see if it moves.
The Chinese have retracted their assertion that they measured significant thrust. I reviewed the NASA paper and they did not build the power source into their device, meaning that they were supplying energy and momentum from outside source. This invalidates the experiment. They also did not account for ionic flow from the device. It's probably just an ion drive, with ion charge being supplied from outside current. They've made a very inefficient cathode that has asymmetric electron boiling.
Why don't you link to these claims you just made please!

In which they state up front the first (among many) of items that completely invalidates the experiment:
"All dc power and control signals pass between the external equipment and vacuum chamber internal components via sealed feedthrough ports."
It is a very amateur error to supply power to a sensitive thrust test from outside the craft unless you are trying to demonstrate remote sourced thrust applications (like fire-hose drive).
Says the armchair physicist. Your so much smarter than Chinese scientist. They should have just sent you the device. We might already have made it to a different Galaxy. Publish your TH-cam thoughts.
Skepticism is healthy, but skepticism in the face of mulitple experiments showing positive thrust.. this is crossing into climate denial tactics. and frankly, I don't consider the word of some random dude on the internet to be sufficient to 'invalidate' anything. this is the internet, and misinformation spreads as fast or faster than information. I'll wait for more experiments before I decide on the technology.
As an architect, not an engineer or math whiz, my intuition says a simple cone shaped chamber is probably just a first step. I'm thinking a more parabolic shape might hold promise.
Spiral my friend
Or something like a particle accelerator, a torus/circle, with a straight offramp?
I love how military applications and defense regarding the technology’s military applications are already being brought up. . .
I really hope we have a plan to deal with this technology, because reactionless drives would allow RKMs to be pretty easy to build. A full working EMdrive which is actually very simple tech would basically mean that anyone with the knowhow, (a terrorist, an enthusiastic school kid, etc.) will have access to weapons that make the death star look like a wet firecracker in regards to the real world.
As with any technological advancement, it make certain things easier. For example, the gun over the bow & arrow. Nonetheless, we will learn to work with them.
The most likely Gilo application would be to lift an ultralight wing on the flying car not the car its self but even that would require the high Q super conductor version. Lifting the wing to the right height is the challenge with para-foil cars. Poles have been used, and small integrated balloons or drones are in the works. The Emdrive would be a order of magnitude below those at best. Regardless of how the emdrive works I would still want wings so we have a fail safe glide ratio if the Emdrive stops working.
Good luck getting off the ground with millinewtons.
The first working helicopter rotor lifted 1 tenth of its own weight not including the motor. This all depends on whether the Q factor scales with some parameters and materials. Hence the super conductor work. I'm a sceptical optimist.
Does the resonating chamber have to be made out of copper or can it be made out of a lighter material ?
It only needs to be conductive. Of course, we still don't have a good, foolproof theory as to how the thing works...
Put a nuclear engine to power the drive in the spacecraft and there is an abundance of energie.
How could superconductor help increase the thrust to power ratio?
I'm a bit surprised people are jazzed about this "drive" when obviously more efficient mechanisms are trivial to imagine and construct (and also powered by electricity rather than conventional thrust). In some ways this seems a bit similar to a much more efficient trust generator that I invented 30 years ago (when I was just a kid).
Thank you for choosing to communicate your thoughts rationally rather than reacting emotionally. My statement is an actual complement to you. Folks are consciously and unconsciously seeking a light at the end of the metaphorical tunnel in an uncertain and changing world. The fact that the EmDrive does produce thrust provides some light. But, it also reminds us that the more we learn, the more we release just how much we really do not know.
One other thought. The working fluid of a jet engine or a propeller driven aircraft is air. The working fluid of the em drive is considered in this video to be space itself. This idea is somewhat hidden by the theoretical details presented but that is what it amounts to. The em drive is a jet engine whose working fluid is space itself.
After learning that the force of gravity is merely the consequence of time dilation (and time dilation is the consequence of the mass or energy density) a tide would be formed in a region where there is a gradient of energy density and therefore a gradient of time dilation. And if a tide is formed a tidal force would be experienced. Normally, an assymetric solid clump of mass will not move along its own tide because... well, the gradient is formed by its own mass and the equivalence principle, in effect the inertial mass is shaped exactly such that a solid object will not self accelerate regardless of how asymmetrically one might shape it. However, given that the photons in the cavity are massless and given the presence of the energy flow between the two plates (assuming the energy is conserved) as the energy flux of those photons traverses from one end to the other a weak (but non zero) energy density gradient, and consequent time dilation gradient is established.... without the inertial mass to go with it. Of course we have the thruster's shell and power source as overhead, but in theory the energy flux we can pump into the volume is arbitrary and only limited by our technology. This gradient would be proportional to the net energy flux, which is proportional to the magnetron power, Q and volume.
It could be great if the emdrive in fact worked. It would also be great if this will help us understand space or matter. In a simple interpretation though, it would be interesting to compare a wattage/time energy loss compared to a mass/acceleration, to see if they can be simply converted.
Presumably the EMDrive and Cannae Drive do not conserve their energy so the question is really only how the RF cavity energy is getting out past the reflective end walls-maybe the 'exponential' exterior waves from '100%' internal reflections do-carry energy not-previously-computed, or, maybe deBroglie waves instead of 'less-efficient' photons... (that'd be #4,5).
Rediscovering the momentum from the bass speaker pointed into a vacuum( pressure) this is very cool no more gas
Nothing wrong with curiosity, but nothing has been proven
Philip Wells One of the best comments in this comment section.
One thing has been proven, the EmDrive does, in fact, produce thrust.
How does Unruh radiation assymetrical cavity pilot wave quantum virtual plasma and quantized inertia explain the conservation of momentum in the em drive? And how does the cannae drive works since it's not assymetrical?
How could it be an hyperspace warp drive?
To produce 1lb of thrust would take 2.224 Mw
So for the little girls EmDrive powered hoverboard
she would need 50, 2Mw Cummins DQKAB Diesel
Generators at 9 tons each, 450 tons
Also a 110 Mw microwave skateboard might require a license
Technology always does more with less. To do what your iPhone does today would have required a huge bank of vacuum tube computers years ago that would have taken as much electricity as a small town.
When is the next video coming out?
Thanks for asking. Warp Drive Part II is finally about to be published, and it's 100 times better! Publication E.T.? By or before the end of next week - for sure.
Good news!
Four minutes in and it's a big fat nothing-burger so far.

I believe the pulsating, swirling photon is the energy unit of this universe that makes up everything in existence in this universe. Everything in existence are photons and interacting photons. Everything in existence is 'light'.
What is called 'gravity' is a part of what is currently recognized as the 'photon'. 'Gravity' would be the force that makes the sine wave of em expand and contract and would act basically 90 degrees to the em forces which of course act basically 90 degrees to each other. Here is a test for the 'gravity' portion of my theory of everything idea. I would do this test myself but do not currently have the necessary resources to do so, but maybe some entity reading this might have the resources, do the test, then tell the world what is found out either way.
a. Imagine a 12 hour clock.
b. Put a magnetic field across from the 3 to 9 o'clock positions.
c. Put an electric field across from the 6 to 12 o'clock positions.
(The magnetic field and electric field would be 90 degrees to each other and should be polarized so as to complement each other.)
d. Shoot a high powered laser through the center of the clock at 90 degrees to the em fields.
e. Do this with the em fields on and off.
(The em fields could also be varied in size, strength, density and depth. The intent would be to energy frequency match the laser and em fields for optimal results.)
f. Look for any gravitational / anti-gravitational effects.
(Including the utilization of ferro-cells so as to be able to actually see the energy field movements.)
'If' effects are noted, 'then' further research could be done.
'If' effects are not noted, 'then' my latest TOE idea is wrong. But still, we would know what 'gravity' was not, which is still something in the scientific world.
Science still wins either way and moves forward.
ben rich former head of lockheed skunk works says they found the mistake in the math(what ever that means) and they now have interstellar capabilities anything youve seen on star trek or star wars theyve tried and either made it work or tried something else and now have the ability to take ET home,im sure all the theories in this video would work perfectly if the fabric of space was plaid.
Are you going to do a follow on your warp drive video?
Next video: Warp drive part II
will we ever have EM warp drive
This effect is fully explained in Unified Theory of Everything. It is really gravitational drive, but construction is simple, therefore thrust is small. With knowledges about gravity and gravitational force, we can simple increase thrust 100 times in similar size on about 100mN/kW, similar to best ion thruster. This principle is good for small satellites, not for traveling to deep universe. Therefore we develop fully functional Warp Drive which works on antigravitational annihilation reaction inside gravi-nuclear propulsion. This propulsion can accelerate with 1-4G on lightspeed, and we can be on any of million habitable planet in galaxy in 3 years traveling.
John Zacek maybe a gravitational drive could move a ship faster than light ussing the space-time curvature.
any news in autumn 2019 ?
Not much: emdrive.com. In our opinion, the EmDrive is not efficient enough to actually function as a drive--wrong figuration. However, that it not what is interesting. What is interesting is that there is any thrust at all--it may have revealed "something"... more on that in the near future. That said, should Mr Shawyer develop a flying machine, we will make another video about the EmDrive. Thanks for asking.
Good Video. I like your open minded approach unlike some in the so called scientific community! - I dont fully understand the drive. I would like to believe. Still, seeing is believing. If some actually makes a working prototype that accelerates a object then I will be more inclined to believe . I am open minded. We will have to wait and see.
leigh pierce Really polite comment.
Thanks for the info!!!
7:56 Professor R2!!! Love him :-).
this thing is in the talks for a while now but nothing really happened. I think its a hole without a bottom, it will never work
The fact that the drive produces more thrust than a pure photon rocket is what has caught everyones attention... asking themselves, "how is this possible."
Could the rear of the EmDrive be creating a mini Hawking Radiation effect with one photon escaping and the other bouncing back?
David Bland no, because the photons are not entangled. Even if they were, that would turn it into a photon thruster.
I wonder if they could use the same principal of microwaves with magnetic waves. Since magnetic force is the strongest of all forces.
Omar142118 I thought the strong nuclear force was the strongest of all forces.
Omar142118 If I'm wrong though, then please enlighten me.
Ly:bInhn DhInhm:Ateidr Yes, for this application. All atomic interactions are a result of the electromagnetic force. Electromagnetic Force is fundamental force
in nature. Electromagnetic force holds atoms together. This makes nuclear force strongest. Since everything in nature is charged with particles by manipulating the frequency of the magnetism you can achieve a far greater thrust that is infinite since magnetism never decay.
Either nuclear force is stronger, but I see your point.
I'd recommend doing a video on the Nassikas Lorenz Thruster!
The liquid nitrogen trials produced no discernible thrust (certainly not the levels predicted). The liquid helium trials have been cancelled pending further work.
Why is this only now leaking out
First scientific publication was in 2002. At first, many scientists viewed it as quackery, but then they realized that something very interesting was taking place, which is why everyone started building & testing them, such as NASA, etc. What is taking place inside the EmDrive reveals something about the universe, in a small way.
Roger Shawyer in England is Created Em Drive theory, But NASA finally break through not too long ago.
I'm highly skeptical of the emdrive and think that a more mundane explanation can be found for its function.
It seems as if we have all the bits of tech to make anything work. But who will put them together?
Yah just hammer one side of your microwave shorter and off you go. No really, I would be so happy to see this worked. One problem is that if we don't totally understand why something works, like quantum observations for example, they may malfunction under some new external circumstance. I wonder where energy is typically lost in these devices besides supposed conversion to thrust, possibly heat loss?
we live in a wonderful time... things like EmDrives... Quantum Tunneling... Entanglement... is right in our reach... I feel we are close...
I think, (hope), that they will be used for space travel more than making people cars float... ;)
We are indeed in interesting times........ and yes, space exploration/travel is the main objective and for really good reasons which we will discuss in a not too distance video. Flying cars will be a natural byproduct.
looking forward to the upcoming video... it will be years before this technology can operate in anything but the vacuum of space though... still, it's totally exciting !!!... :D
Even if the EmDrive works, the thrust would be so miniscule that the claim to fly a car with it is laughable. The only application is for space probes.
Could we be at the point where new laws of physics are to be discovered? Just because something doesn't conform to physics as we currently understand them doesn't mean that it's not possible. This is where we learn the next chapter as we write it.
The microwave towers motion when first started they couldn't explain the towers movement's thinking wind as the causal but scientists wouldn't confirm or deny it had something to do with the same effects.
The only real question is the status of the high Q, doppler compensated version. That is the drive of real interest. The rest is only a tease. Until someone thinks they have the know how to build the third generation and does so we can only wait. Given the third generation the settlement of the solar system will be possible as well as cities suspended in air. Truly a new world.
Nice explanation! Has anyone seen Netflix's Salvation?! (scenes should be used instead "Back to the Future")
Similar to the photon compositor a storage and released .if a Transistors of vacuum tubes had frequencies as well they could have discovered it sooner .maybe Tesla had .
Nice video, what is the next one about??
Next video: Warp drive part II
dont get why the em drive is getting all the hype. woodward based drives seem to be more intriguing as it starts with theory and then builds a device to exploit theory, rather than trying to prove a magical invention works.
The EmDrive is not the only drive. In fact, we will be creating a video about the Quantum vacuum thruster after Warp Drive part II.
Don't know if you didn't mention this because you're trying to push a narrative for youtube views or because this video is old and you just didn't have the info at the time but it's looking more and more like the thrust being given out is a result of earth's magnetic field interacting with the drive's electronics despite the shielding around the experiment: when the Drisden study opened the experiment chamber and manually rotated the engine rather than rotating the whole chamber, they found that the direction of the thrust did not change as it should have. They then went to formulate a model of magnetic field engine interaction and the math was consistent with the thrust findings. This is the same group in Germany you mentioned in this video. Maybe we'll have hover tech in the future but this engine will not be what powers it.
It makes thrust through convection/pressure difference caused by heat difference of parts of device and remaining gasses - near vacuum in test chamber, could be outgassing/sublimating away part of itself or container, radiant (photon) thurst and magic pixies (hf radiation + sensitive opamps, + current loops through low intensity invisible glow discharges = bad ;-) and human errors ;-) messing with your "über sensitive - i mean it, i wouldn't wonder if it can detect g-changes at solar tides ;-) mechanical force sencors.
I am hearing impaired. Could you leave out music please!
So 1.2mN/kw means you need to input 833.33 MW to accelerate 1kg. Put that into perspective, the average car engine weighs up to 2,000kg and puts out about 0.074 MW. Those numbers don't add up to zipping around at speed. The plant required to power this and therefore provide significant thrust will weigh many times more than that, but seeing as the plant is so heavy I'd be amazed if it even twitched.
So all this bullshit about "hovering" cars is just that, bullshit. The only place this may be of any use is in space, but given that we already have better, more efficient ways to accelerate bodies in space what's the point?
What is stated in the video:
"So, are we really going to have flying cars in our future?
I'm sure that before too long-we will have unconventionally propelled flying vehicles, though they may not look anything like what we have come to expect-and, they will most definitely be equipped with artificial intelligence.
>>Whether the EmDrive or something like it will be used in these vehicles or not, is too soon to know.
Ok is it even a significant amount of thrust?
Results from testing have been too inconsistent. Some have measured force in the "wrong" direction. Several have noted no forces at all. To date devices producing thrust have never been observed to produce thrust when mounted on a platform with their power supply, strongly suggesting that thrust may come from interactions with electromagnetic forces by the power cables, with net-zero effects when both ends of the cables are measured. AFAIK this is still in the realm of "needs demonstration of sustained force that accumulates into actual velocity, in a vehicle with onboard power supply, before I believe it."
You postulate that photons flip between being waves and particles? Take a first year quantum mechanics course. Neither classical waves nor particles properly describe behaviour on a quantum scales. The simplest description is that they are a "quantised" burst of waves with a wave function which describes it's position an momentum, really they don't fit into either a wave or particle description. These are only constructed names given in classical mechanics to simplify calculations
Roger Shawyer gives a perfectly sensible and accurate description of how his drive works. The principles are based on standard Einsteinian relativistic physics. People objecting to the explanation just don't understand the basic principles of relativity. No exotic explanations are necessary and that is the true genius of the device. It is so simple that only a real genius would think of it. No laws of physics are being broken here, just do the maths. Roger deserves the Nobel Prize for this and those sceptics who don't understand how to apply the equations of physics are acting shamefully.
uhm no.
You really think anyone who perfects it will willingly release real data for anyone to replicate it. The ones who own this technology will control the future.
Ok. The EM drive tested by NASA measured 1.2 millinewtons per kilowatt. To put that in perspective, our favorite time travel car, the Delorean, uses 1.21 gigawatts. That amount of power is equal to 392.04 foot-lbs of thrust. To put that in perspective, the 3.5L Ecoboost engine from Ford creates 420 foot-lbs.
Your videos are fun but aside from conjecture, there isn't much substance.
+hgfrkytdh 1.2 millinewtons well below the noise/interference floor in the presence of any electromagnetic effects.
O yes! It will replace current propulsion system. Energy of "Nothing" is too great... there is only one problem... can energy meter be fastened to the "Nothing".
Seems to me that the EMdrive might be creating a subatomic Nuclear chain reaction with space time radiation
Why are these different hypothesis called theories rather then hypothesis?
The colloquial meaning of the term "theory" is the opposite of "fact", it is a guess, or hunch (what a scientist would call a "hypothesis"). But in Science, the meaning of the term "theory" is totally different. Theory and fact can be the same.

The British, the people that invented the magnetron during WWII to use it in radar systems are now wondering, "what the hell?", as they roll around in their graves. I am wondering what the hell an wanna know what's for dinner. I also want to know why isn't the cavity filled with something if bouncing around is important. I suppose that would make the nugget filling the thruster medium and the microwaves the thruster as they are. It would only make more sense as the exhaust becomes the microwave beams feeding back on itself. That's my second advise on the concept that I don't care very much to support in anyway. Sherman W Braithwaite © Tuesday, March 30, 2021.
The EM Drive presents-illustrates another discovery in science. This is the reason for the videos. Likely by the end of this year we will discuss what that discovery is.
How about building a device that make photons that "cancel" each other out purposely instead of this primitive prototype that seem to be built accidentally and not on purpose to test the theory of that giving the trust?
Radiation pressure can create trust in open waveguide only and is extremely small and useless for driving...15 years ago I have invented real propellantless drive using EM waves but is has small thrust force to power ratio...So I have invented another type propellantless drive which is not using EM waves and has extremely large force to weight ration capable of lifting itself and a large payload...
I am the original designer for this drive. The original concept involves a sharp tapered cone on the end of the cavity. The principle was the photons would undergo many more reflections in the conical section than in the flat region near the microwave input. Since the same photon deposits more momentum in the conical section than in the flat portion causing an asymmetry of momentum in the system where more momentum is deposited on the conical side. This momentum imbalance was hypothesized to cause a force in the direction of the conical section.
The theory is sound all we await is someone to demostrare this principle in the lab. Good luck fellow star travellers.
"They will most likely be equipped with artificial intelligence" BUT WHY THOUGH? Its like saying wooden pencils need a vision reactor to work. Just saying seems very unnecessary for driving a hover car.
Screens out human error, human error is why cars crash
Newton was wrong?
John Roach nope, just incomplete, newton doesn't has the tools to understand all the fenomena involved on nature, after einstein complete part of newton work, but still a lot of fenomena that are waiting for an explanation.
Both of these drives are almost proved to be fake
At WHERE? Shrivenham? That is NOT said Sher-iving-ham
Yay, we will have flying cars that grill all living things below them. Great invention...
Ok, the microwaves are in a cavity, but leaking might still be an issue.
Maybe try thinking before you let people read what you type......
Obviously if that were to happen we wouldnt use them in that state.
Next time without the background music, please. It is super-annoying.
I prefer the mach effect drive. It's more of a gentleman's drive.
Very interesting .
Let's stop playing around and get this thing into space to see what it can really do.
According to China, they have already placed not one but two EmDrives into orbit.
Its this asalation of phase canslation thing that made me turn away from this whole microwave rattle can idea of pushing a ship a few years ago. But if the Chinese are being forthright, maybe I would consider it useful for a probe or to drop satellites onto orbit for remote sensing and cartography, though I'm still not sold on the idea...
My apology for my spelling, my mind doesn't fallow such things.
The emdrive motor still requires electricity so it is not perpetual motion, so i don’t see any benefit of such emdrive motor, if we want to make it perpetual , we should hook it up to a magnet motor to supposedly generate invinitive trust.
It is *not* a perpetual motion machine. Within the EM Drive a previously unknown effect is taking place, this is interesting and therefore requires further research.
Already KESHE foundation technology has made flying car, and also KESHE technology students made at least one car, as far as I know. And Iranian government has the KESHE technology.
looooooool ok dude
The best video on EMDrives I have yet seen. There is a little more with the history of proponents & detractors like hard vacuum tests but still the best vid. Monomorphic just put a drive on www.thingiverse.com/thing:2505612 Jim Woodward should get a mention though since he has been working with Mach Effect thrust since about 1992.
"With" what do they interact "with"? This guy sounds like an announcer. To bad he did not take English in school.
