Damn, I really need to set up the disk and the Great Tesla coil to test this.
Even a car ignition coil could provide the linear pulse to the disk while the Tesla coil provides the voltage kick into the Aether…pg
Hello,nice share.
When I originally commented I clicked the “Notify me when new comments are added” checkbox and now each time a comment is added I get three emails with the same comment. Is there any way you can remove people from that service? Thank you!
I have the same problem and have no Idea how to fix it except for you to unsubscribe to the service
Hello! I know this is kind of off topic but I was wondering if you knew where I could find a captcha plugin for my comment form? I’m using the same blog platform as yours and I’m having trouble finding one? Thanks a lot!
Reply; If you really examined my blog you would know I don’t use that thing…pg
pg – just occasionally, spam is useful. Made me look at this article again.
One of the things I worked out in the intervening time is that, since the waves move at some limited speed, the force that wave can exert changes direction with the position on the wave. This works as well with sound waves (longitudinal) as EM waves (transverse). Momentum transfers are force multiplied by time. Since the force exerted by the wave changes direction relative to the force being put in, then the only situation in which momentum is truly conserved is when we’re using an unchanging field. When momentum is transferred by a wave, it is not necessarily conserved.
For your electrical pulse, the rate of change at a particular point determines the size of the force it can exert. The phase change (because of the distances involved) will be important in determining the direction of the force.
Whether or not there’s an Aether, we can in fact measure the effects of an electric or magnetic field, and the force it produces on a charged particle such as an electron, proton (or nucleus as a collection of charged and uncharged particles). There’s also the speed-of-light time delay between a current producing a magnetic field and *something* responding to that magnetic field some distance away.
When you’re using a Tesla coil to produce the electrical wave, then the wavelength will depend on the frequency of oscillation of the coil. By getting the system into resonance, you get much larger voltages and currents than for a non-resonant load, which means that the forces involved will be much larger (by the Q of the system) than a non-resonant system.
We’re thus getting to a situation where by putting a frequency into one part of the system that’s 1/4 wave phase difference to another part, and where the distance between those two parts is also 1/4 wave, that by the time the magnetic wave from part 1 hits part 2 it’s in one phase relationship, and when the wave from part 2 hits part 1 then it’s 180° different phase. The forces on both are in the same directions, rather than being equal and opposite. This is pretty simple and is easily derived from the standard textbooks.
It’s not really “kicking the Aether” here that does the job. It’s the phase relationships of the two parts of the system relative to the spacing between them, so that the forces produced are not equal and opposite but instead equal and in the same direction.
Depending on precisely how your disk reacts that might happen, though I think you might need to get the frequency right in order to see any large effect. You need to have the various parts of the system in resonance, and of course at the voltages and currents (and low inductances) you’re using even a few pF of the surroundings may change the frequencies enough to go out of resonance.
Without the resonances, the forces involved will be very small. For a test-case with 100mW of 5.8GHz RF it worked out around 0.1 micronewton. Very hard to measure that. Still, with resonances added that could maybe be multiplied up, and waveguides can have a Q of 10k or more. Almost getting to enough to measure then. I think this is why the EMDrive produces a thrust, since there is some interesting wavefront shapes inside it and the phase relationships of the magnetic field and the skin currents may well be enough to produce a unidirectional thrust. Looks like it doesn’t need any really complex explanation, just a realisation that though a constant field is conservative, a changing field isn’t because the speed of light is finite and not infinite.
@Simon; I am also glad that I decided to allow that spam to post, It was almost acceptable. 😎
I read your essay 3 times to grasp it all. ?? maybe.
I think your observation of shape and wave guides is spot on, but I think the useful effect is external rather then internal. Your back of the envelope engineering is a bit beyond me in the electronics involved ,but I would suggest we should think in about 10 meters or 40 feet in size for the active shape in a real device. My 3 meter disk is the minimum size that I hoped would give a measurable outcome.
Voltage stress into the environment will give the most effect in it. and the shorter the wave length the closer the standing wave will be to the surface of the active element. The inverse square law really bites into the useful energy as you get very far away from the skin….pg
pg – I’ve been learning a lot about how to deal with RF over the last year. It always was a black art (that’s why there were never many true RF engineers, and they got paid a lot) but once something has been designed and shown to work, a replication of that also works. It does however need to be accurate enough, and the odd 100 microns can be the difference between something that works and something that doesn’t.
With RF, using the same shape and geometry and shrinking the size simply means you need to use a higher frequency to get the same results. The impedance of each part depends on the geometry and the dielectric constant of the insulators. As such, if you think it’ll work at 10m diameter, but can only build 3m diameter, you need a higher frequency. I can’t remember what frequency you’re actually using, but of course sparks have a wide range of frequencies in them anyway. The problem with sparks is however that that wide range of frequencies may not have a high power in the frequency you actually want, so most of the power input won’t do anything useful.
Within your glassfibre, the waves travel slower (ratio is the square root of the dielectric constant, which will be between 4 and 6 depending on the glass to resin ratio, so around half the velocity) and it’s not going to be easy to work out how the wavefronts travel across the disk. Still, the basic idea will be to produce a charged surface in an electric field where, as the wave travels, when the field changes polarity then the polarity of the charged surface will change as well. The charged surface will thus see a force in the same direction whether it’s charged +ve or -ve.
What needs to be done is to find out at what frequency that will happen in your disk, and then use just that frequency (since other frequencies will either not produce that single-direction force or, worse, produce a force that changes direction at some beat frequency and thus average to zero).
I’m working at a much higher frequency (around 5.8GHz) because it’s quite easy to buy transmitters and amplifiers in that range because of the drone craze. A loop antenna for that is around 4.2mm diameter, and to get that in resonance I need a capacitance of 0.0775pF. The wavelength in air is around 52mm. Looking at the resonant cavity, the largest dimension is around 42mm, and the problem is in getting a high enough Q. I’m using Silver-plated brass for that. Fairly close by now to having all the ducks in a row and being able to test it out and see if there’s any force produced. Get it all tuned up at a few mW and then once I’m sure that the tuning is right and I won’t release the magic smoke from the transmitter I can run it at around 3W or so.
The thing about this is that it’s really independent of whether or not Aether exists. That also applies to your disk. For the disk, we know that a charged surface will experience a force in an electric field, so if you can ensure that the surface always has the right charge to produce an upwards force then it will work (the field and the charge change at the same frequency and in the right phase relationship). Same with the microwave version I’m testing, in that putting a current-carrying wire in a magnetic field will produce a force, and so if the field changes polarity and the current changes polarity at the same time, then the force will be in the same direction. I’ve gone to magnetic fields here because it’s easier to get a larger force using low voltages (so it’s a lot safer than huge Tesla coils) but the principles are basically the same. This doesn’t depend on any particular theory being true or not, but on experimental evidence that a charge in a field sees a force in one direction, and that a current in a magnetic field sees a force in one direction. After all, that’s how we define the fields and measure them.
The other thing about using a resonant cavity is that those microwaves are enclosed, and the cavity shields me from them. It’s rather nice that the Q of the cavity also gives far stronger fields, too, and it’s also not going to be affected by stray capacitances in the environment. With the disk, you don’t get those benefits. The upside of the cavity resonator is that it takes far less materials to make it, the downside is that it needs to be accurate to less than 100 microns, which is a little difficult and takes time.
Logic says it ought to work, so it’s down to getting the experimental details right.
