I suppose that could be one valid theory on how the capacitor charges, the point to plate rectification idea. That seems like a reasonable explanation. - However why then does it seem to charge only from the light globe filament or glass? Rather than say from a wire or the air where there is also lots of RF? (Just going by what I’ve seen from the original Borderlands video). It would be good to know what Eric’s conclusion is on that particular aspect. As the bulb filament is hot, like a hot cathode, but it’s not a cathode as such, perhaps rather it’s a hot ‘anode’ if you will? Honestly, I don’t know. - Your suggestion does seem valid as the sharp point worked best, while a plate contact didn’t work.
– However, I do know that the termination from a Tesla Coil can have a DC component or a beam that projects out from it and it can be measured with an electroscope, as I have seen the TCBOR people measure this (on video). So I originally thought it was an effect like that, except emerging from the bulb instead? - So I guess the jury is still out on this one just for now. - Anyway it is still interesting and hopefully I’ll be able to experiment with this myself in the near future.
