One side of the secondairy coil is grounded, so never ever ac on his device.
Well, why should AC not be possible, if you ground one side??? Doesn't make sense to me? Would be nice, if you could explain a little farther what you mean. Take a any transformer and ground one wire. You will still have AC. The only difference would be, that now the overall potential is not floating anymore, but has a fixed reference potential.
I think Puharich even states himself somewhere, that the cell has rectifying capabilities. E.g. look at his Blood Patent. The circuit is very similar. And there he shows the equivalence circuit of the media, which is exactly as I would expect it to be: Namely a diode with a resistance in series parallel to a capacitor with a resistance. My guess would just be, that the behaviour is voltage dependent. E.g. for low voltages it is obviously a capacitor. For high voltages it is a resistor and in between probably acts like a diode, if the E-field is inhomogeneous. this is at least my current hypothesis.
@Don:
Thanks for the comment. As I looked again at the pic, I realized my mistake immediately. Let's blame this due to the fact, that it was very early in the morning, when I looked at it...
The big ones definitely look like the rectified AC. But honestly, this pic arises more questions than it answers.
One thing is obvious. The frequency of the coils is definitely quite higher than the 120Hz of the rectified AC. This at least answers one question for me, for I was quite astonished how he could get such a low resonance frequency with just such a small coil, with not that much windings.
Did you make that PIC? It would be interesting if it was made really with just such a low voltage, or if a 10xprobe has been used.
All in all, this now really started my interest in this "8xA circuit". I will definitely now do some more experiments on it.
@Tony:
Hmm looks like I will have to do some experiments to the diode behaviour of the WFC. But one has to be very cautious in measuring a static condition with a multimeter, for a WFC acts also like a battery. And this can very much alter the measurement if you use low static voltages from a Multimeter. I think only a dynamic measurement could really definitely give the answer under what conditions a WFC starts to behave like a diode.
