Re: [Vo]:Resonator shaped like a hyperbolic vortex
Hi, BTW, it only costs about 0.53 kWh/kg to lift something 200 km above the Earth's surface against gravity. Li-ion cell phone batteries have about half that. However gasoline is about 12-14 kWh/kg, less when you need to take along your own Oxygen. Ideally one would use a small nuclear or isotope reactor.

You don't need a leaky EM drive for a photon rocket. An ordinary radar dish will do just fine.

Wonder if they were kept any drones aloft for the whole time? Say, having enough microwave energy to power a drone might mean that they could also test a hybrid resonant cavity so both things could be going on. I suppose that it would be possible to design an EM-type drive, especially if one can be made of superconductor, where some of the RF energy bouncing around in the cavity is allowed to bleed out in a single vector, and thereby act as a photon rocket engine in addition to whatever else is going on.

They're really probably testing a defense system against aliens. Cheers!
Re: [Vo]:Resonator shaped like a hyperbolic vortex
Speaking of resonant cavity devices, state secrets and the EM Drive specifically, there is this: https://www.universetoday.com/143870/x-37b-lands-after-780-days-in-orbit-doing/ It is strongly suggested that a prototype EM Drive was aboard. No comment from officials. Despite the fact that most scientists still do not think it is feasible, the silence from NASA about the testing in space - is palpable. Let me say again that Logan's geometry would stand a good chance of being superior, if the concept does work, since the area ratio of the surface area of the ends is far greater and that ratio seems to be an important criteria. Instead of say 3:1 it could be 100:1 or more. Using that increased area are might entail providing several different RF frequencies instead of one. Jones

That is why, for example, even though the air is moving in circles parallel with the ground, a house gets sucked *up* the vortex. Because there is a low pressure zone inside the funnel. I suppose if you have a vortex made of some other medium than air, analogous phenomena may occur. If you have a vortex of "space" or "aether" or whatever you want to call the medium through which radio waves propagate -- I guess you could have a low "pressure" zone relative to the surrounding volume. > If you can pump enough out to equal the weight of the structure, than the > net weight would be zero.

Now try to imagine a place where the aether density is less than in the surrounding space. Photon pumping might produce such a thing? Probably best to start off in a normal vacuum so that air doesn't confuse the issue. If you can pump enough out to equal the weight of the structure, than the net weight would be zero. Any less, and it would be negative and you would have an anti-gravity device, analogous to a hot air balloon, but capable of operating in outer space. This is based on the notion that a gravity well comprises an aether density gradient. All far fetched nonsense? ;)

The Wiki listing for "resonant cavity thruster" is a place to start as there are good links to more detail https://en.wikipedia.org/wiki/RF_resonant_cavity_thruster There is a long thread on Reddit if you have a few days to waste Sean Logan wrote > Can you refer me to some good papers on the Shawyer truncated cone?
Re: [Vo]:Resonator shaped like a hyperbolic vortex
Thank you JonesBeene. The thought that the mass of the device may change under certain conditions had not crossed my mind. Can you refer me to some good papers on the Shawyer truncated cone? Yes, I am familiar with Bird Wattmeters. However, in this experimental setup, nothing is matched to a 50 ohm impedance, so I think it may be simpler and more straightforward to simply measure the Drain current I_d. Imagine a simple Class A NMOS amplifier, with n LC circuit between the Drain and the positive rail. In my experiment, the hyperbolic horn structure serves in place of the resonant circuit. The current flows down the central pipe in the middle. The current varies in magnitude, but never reverses direction. Therefore, the magnetic field varies in magnitude, and gives rise to wave phenomena, but does not reverse direction. Therefore, the hysteresis curve stays in the upper right-hand quadrant. I think of it like stirring a bucket of water. If you stir only clockwise and do not reverse direction, you will begin to create a vortex. The surface of the water will dip down and form a funnel, shaped like a hyperbolic horn.

RE: [Vo]:Resonator shaped like a hyperbolic vortex
Very interesting. The first thought that came to mind when I saw your design, esp with the golden rule geometry -- is that it could be a more favorable wave guide than the Shawyer truncated cone (EM drive) for the purpose of directed thrust using RF. Mabye this is where your are headed but if you haven’t done so (and have a very sensitive digital scale), it could be worth the effort looking for any such small effect. NASA would love to see such a finding as they have taken some heat, so to speak, over their EM drive testing. As for power measurement, there is lots of used Bird RF meters and dummy loads out there (EBay) – but it looks like you have already tried that. Jones From: Sean Logan I built, and am experimenting with an EM resonator. Its geometry is based on the shape of a hyperbolic horn, the natural shape of a vortex in water. Please let me know if you have any insight into what is happening inside this structure, when it is excited with RF. My work is documented here: spaz.org/~magi Also, if you know of a simple circuit for measuring RF current, I am all ears. I would like to look for the "dip" in current which occurs when it is excited at its resonant frequency. Thank you, Sean Logan
