Assume 3 hollow copper cavities, one at sea level, one in LEO and one in geosynchronous earth orbit. Name all the particles/fields that could ingress the cavity in each reference frame.Gravity and neutrinos.We need to consider speculative or theoretical bits as well: dark energy/matter, unruh radiation, and several others that fall outside quantum, relativity or classical physics. The problem with those is being able to quantify them.

Todd, in your theoretical framework as I can simplify it for my understanding, a difference in the internal dispersion of energy towards the large end results in the force generation towards the small end.
Further, that an integral part of the calculation is the existence of a dampening factor, that is mathematically identical to gravitation, as an influence WITHIN the frustum that is required for the energy dispersion to occur. Is that correct?
Yes, you're missing something because i didn't explain it correctly, sorry. The small endplate isn't attached or soldered to the sidewalls and the sidewalls can slide past the endplate. This keeps the distance between the endplates the same but allows the cavity to expand and contract. The endplates are ceramic with bonded copper so they will not even warp.
Hope this helps.
My Best,
MichelleJust curious, if the small endplate isn't sealed to the sidewalls, how do you prevent all the RF from leaking out?It's sealed using a Beryllium non-arcing gasket around the outside.

Theory Question: Shawyer's theory basically boils down to the wave nature of light, am I correct? Can experiments be designed around water waves or sound waves to prove or disprove his theory?
I can imagine an experiment in which a 2-D frustum with curved end plates is set floating in a bath of water or some other fluid. Waves can be generated from within this frustum by dipping some oscillator in the water. Would these waves cause the frustum boat to move fwd or backwards? What about an acoustic frustum?
I'm working on an experiment to test this as a temperature gradient in air. it's non-relativistic, but depends on the "jerk", the time derivative of the differential power dissipation and pressures.

Seems to me a proper theory would have 1) Open system concept 2) Energy (field, particle, etc) that is equal in all locales. Seems if whatever external link there is, it must be pervasive at SL, LEO and GEO or very close to being equal for the thing to be a useful spaceflight tool.
...Could the mode shape in the frustum serve to directionally focus ambient neutrinos that do have mass and respond to gravity, that would exceed a perfectly collimated photon rocket? ...

I think Todd's theory allows that the resonant mode shape creates "something" that mimics/is a gravitational effect (accelerating frame). If that is the case we know that neutrinos are effected by only the weak nuclear force (which is not present in open space as I understand it), and gravity. Could the mode shape in the frustum serve to directionally focus ambient neutrinos that do have mass and respond to gravity, that would exceed a perfectly collimated photon rocket? WAY beyond my knowledge, but I also think that collimated neutrinos passing through the frustum could then be classified as an exhaust.

ShellI remember that when you initially designed with the beryllium gasket, you were concerned about potential out-gassing past the seal. Did that occur as you tested?

Shell, by beryllium, I'm assuming you mean standard beryllium copper "fingers", used industrially to help shield radio frequency enclosures.
If my assumption is true, a tip for you. If you heat the beryllium copper spring material with a torch, gently, just until it is barely red hot, and quench it in 5% sulfuric (battery) acid, it will loss its springiness. The acid serves to remove the oxidation from the heating process. You can then form it very easily to just about any shape, almost like dead soft copper. Then re-heat it while submerged in a high temperature oil like Krytox 102 to 600-650 degrees F for one hour, and it will go back to spring temper. The oil serves to prevent oxidation during the heat cycle.

ShellYou may already be aware of this, but a public safety announcement is useful here. Beryllium is very toxic and carcinogenic, so only trained professionals with proper safety equipment should cut, grind, sand, machine, etc. If you aren't doing anything that could possibly generate small bits of it, it is less hazardous, but still should be handled with care.

Slight offtopic question, cause i have a feeling the answer isn't anywhere else to be found on the internet... Does anyone know the "special layering" of the superconductor that Podkletnov claimed to have had made by someone for his lab?
Maybe someone at NASA has such details from the correspondence with Podkletnov... Cause i understand NASA at some point talked to him in order to attempt that replication.
Or maybe someone has his email address? Just pm me that and I'll ask him myself.

Soft Copper is a better gasket material than springy Beryllium. Copper washers are used in vacuum systems. They are squished between stainless flanges for a perfect high vacuum seal. That is what you want to contain RF. Beryllium finger stock is used in RF cavities for low impedance continuity between adjacent parts. However the RF-tight seal is usually achieved with a recessed or nested and tight fitting cover. Sometimes a conductive O-ring is used as well. That would not be practical for an em-drive cone because the metal used is too thin. Maybe a flat gasket made from conductive rubber could be used between the cone flange and the big end. Some of it is impregnated with fine Silver wires. However I think having two flat Copper surfaces and plenty of bolts to join them is probably good enough. The thermal properties of that configuration would be ideal.
