Nice pictures!
However, I think the effect we're after has to do with harnessing radiant energy, just using a different way Bedini is doing. And radiant energy is a totally different beast then ordinary electricity.
As far as I understand, it is the electric field itself, which travels at the speed of light and is probably the actual cause of electric currents. On one hand, it appears to behave like a very thin film of water flowing around matter, and on the other hand, it appears to be able to spread out into space.
So, when you put a spike on a wire or a rod (like BEMF coming from a coil), you first get the electric field to expand just outside your circuit, apparantly staying very close to matter, and then the electrons inside arrange themselves according to the field that is present outside the circuit, which on
its turn creates a repelling electric field, much like the "back EMF" you get from a collapsing magnetic field.
This is the view I got after studying the papers by Eric Dollard, which are a very good introduction IMHO, even though there appear to be some errors in some formulas, IIRC. Eric Dollard appears to be about the only person that was capable of replicating
most of Tesla's experiments:Eric Dollard Notes (1986--1991)
Based on this, I don't think oscillations are the key. Radiant energy is all about pulsed DC with sharp gradients, *not* harmonic oscillations.
Another paper that might be interesting is "ON LIGHT AND OTHER HIGH FREQUENCY PHENOMENA" by Nikola Tesla from 1893(!). Really nice to read his almost philosophical introduction about the human eye, but there's more interesting things.
First of all, he talks about how he uses spark gaps and mentions what carbon is used for:
"When the current through the gap is comparatively large, it is of advantage to slip on the points of the discharge rods pieces of very hard carbon and let the arc play between the carbon pieces. This preserves the rods, and besides has the advantage of keeping the air space hotter, as the heat is not conducted away as quickly through the carbons, and the result is that a smaller E. M. F. in the arc gap is required to maintain a succession of discharges."
What he describes about the use of spark gaps is how to create high voltage, high frequency DC pulses. Therefore, I think you can replicate the Gray tube without any spark gaps at all using modern semiconductors, which after all were not exactly readily available in the time of Tesla, which is supposedly the basis of Gray's work.
However, this is just an opinion....
