I watched your DVD of lecture on radiant energy. Some of the requirements as I understand them are:

1. The mass of material of primary and secondary has to be equal as precisely as possible. That is the requirement proposed by Tesla regarding his high frequency coils and especially his flat archimedean spiral coils. I may be way of the track on this one but it seems to me that the amount of the dielectric charge (or rather the density of dielectric lines of force) are in some way proportional to the mass of the conductor or rather to the number of atoms available in order to resonate and produce radiant energy event. For example I've conducted a number of experiments in which I compared the highly saturated high quality ferrite core with small airgap (in order to increase the saturation point and to store more magnetic flux in the airgap- I'm talking about 0.1mm airgap and smaller number of turns of conductor. I compared it with the extremely heavy coils with smaller core (in this case Metglas ones- I used them for their high permeability and extremely narrow hysteresis curve) and open geometry (pretty much similar to the Bedini SG coil). Of course one can produce pretty much the same voltage spikes on both coils but the coil with the more conductor mass exhibit a somewhat different properties. For example the discharge of the capacitor filled with the Back-EMF from the ferrite core showed different properties compared to the discharge of the capacitors filled with the BEMF from the massive coil. I'm talking here mostly about visual and auditive quality of the discharge. My guess is that a mass of conductor definitely plays some role in the way coil produces BEMF.

2. The surface area of the conductors definitely plays a role in radiant energy release. The fact is that a Litz wire or a flat strip of conductor material shows much better properties dealing with sudden impulses. I also compared several types of wire in the pretty much similar conditions (same core, same number of ampere turns, same current and same saturation of core. The BEMF curve of the Litz wire and flat strip wire are much more steeper (thus more sudden in time) and goes to the much higher voltage. I couldn't believe a geometry could make such a difference but it did. My guess is that a conductor tube would exhibit pretty much similar characteristics- in fact I used copper tubing for Tesla induction coils primaries and they definitely show more appropriate behavior and less loses than the full conductor profiles. Of course much of that behavior can be attributed to the lower impedance those kind of big surface conductor shows when dealing with sudden impulses. The other thing I observed is that Litz wire coils sometimes gain by separating of their turns somewhat. The flat strip conductors also benefit if one winds them in a way to be oriented edgewise to each other. It surely lower their inter-capacitance and probably contribute to the lowering of the impedance of coil itself. Skin effect also plays a role in that effect but I'm not sure to what extent.

3. For Tesla resonant system it's advisable to have secondary set to 1/4 wavelength of the resonant frequency. Tesla himself advise in that direction and although I never experimentally tried that rule I guess there must be some rationale behind it. I know that if some conditions are met a stationary wave can be produced and in energy transfer it plays significant role. To be honest I'm still learning about this stuff so please cope with me as much as you can.

4. When talking about BEMF as a kind of radiant event I've learned that inductance plays significant role. With higher inductance one usually gets more severe potential gradient change (measuring with an oscilloscope it means one gets higher voltage spikes). With lowering of capacitive component of impedance voltage spikes go even higher- it's probably why flat strip conductor (for one layer coils- I've never tried multilayer coils of this type) shows significant advantage over ordinary round- profile conductor. It's surface is also extremely large so it could also play a role regarding a skin effect.


So here it is- and although there is so much more I could say about the results I obtained for now I will reduce my ranting on refining my knowledge on the phenomena I talked about. I've based my conclusions on practical experiments but my interpretation oethe results might be wrong so feel free to correct me. I'm always glad if someone disprove my conclusions with solid arguments so that I can learn more about the topic in question.
