Clarence, a.king21:
I'll try to keep this fairly short, since this is drifting off topic.
I am not trying to put down Don Smith in any way, but I have tested a fair bit with some of the things Don Smith
has talked about or shown, and I have found in my tests that things do not end up working like Don Smith describes it.
Regarding his capacitor plates driven by a high voltage AC driver, the first thing most people will probably notice is that
capacitors are used all over the place in AC circuits and they of course most certainly do draw energy from the driving device.
Don's premise seems to be that since you are drawing an arc from the HV driver to Earth ground, and Earth ground is
isolated from the HV driver (in the 2006 demo he used a battery powered power source for the HV driver), that no energy is
being drawn from the HV driver when the second capacitor plate is arcing to Earth ground. However, in my tests where I monitor
the input current to my HV driver from a 12V battery, the input current to the HV driver increases from about 350mA at idle to
about 420mA to 450mA or more when arcing to either Earth ground or even just to a completely insulated screwdriver tip.
This shows that any arcing (even to the insulated screwdriver tip) is drawing its energy from the HV power source to
cause the arcing.
With Don Smith's stuff it seems that it comes down to Don Smith either leaving out key info which you would need to
make his stuff work, or he was just plain wrong about certain things. Maybe Don Smith's use of an aluminum plate and a
copper plate makes some sort of difference, as I just tested with a normal HV pulse capacitor. It is probably worth a test
to see if there is any difference at all however. Also, in my tests, the voltage waveform on the Earth ground side
of the setup is identical to the voltage on the HV driving side, i.e.; if you are using a sine wave in, then you will see
a sine wave on the output ground discharge side as well. That's what I saw in my own testing anyway. If there is a way to get that
sort of setup to pull in extra energy from the ambient to power a load without drawing its energy from the HV power source,
I personally haven't figured it out (yet) anyway. I am still experimenting away...

Anyone can experiment for them self to see
if they can get different results, but make sure you know what you are doing first when experimenting with high voltage.
Good luck with the experimenting.
All the best...
