Hi Gary,
Thanks for all your answers!
#1 Ah vs Wh / COP
I’ve read through the results on your website of your SSG and also started reading a bit about the difference between Ah and Wh, to have a better understanding of the two and thus being able to understand which one is important in which situation/comparison.
I understand the Ah COP calculation of 1.25 you make (not including mechanical work). However, you say that if you compare Wh, you end up under a COP of 1.
I would say that it is the COP over 1 for the Wh (or actually work done / Joules) that we’re after and the Ah COP is not so interesting. But apart from that, I tried to calculate an energy (in Joules) COP based on the info on your website and I end up with a COP higher than 1, not lower, see attachment. Did I make a mistake in my calculation?
#2 Swapping primary / secondary battery
I’m a bit confused now with your statement quoted above compared to what you said about this in post #218. Maybe the confusing arose based on my initial (or John’s) choosing of wording:
When in post #217 I referred to John saying “you run them both down” (when swapping primary and secondary), I did not mean that both batteries would be damaged, but that you empty them both out eventually. Now this seems in line with what you state in the above mentioned quote.
#3a 1-Ohm resistor experiment
I thought I ordered a 1-Ohm 0.6W resistor and a 0.5-Ohm 6.5W resistor, but it seems that I accidentally only ordered the latter one. So I put the 0.5-Ohm 6.5W resistor between the output wires and started my SG:
-Neon bulbs where off (as they should)
-After +/-1.5min the resistor became luke warm. After +/-3min it was warm. After +/-5min it was hot, could not touch it for very long anymore.
Since this was 6.5W 0.5-Ohm resistor, I expect that the 1-Ohm 0.6W resistor would have gotten hot way quicker.
I just finished DVD 25. In that DVD John tells about the flickering / intensity of the neon bulb being an indication of how well the circuit is tuned. In order to have more validation /analyzing data for the results as mentioned with my 0.5-Ohm resistor, I disconnected the resistor and filmed the “disco” of Neon bulbs for a bit. The video can be seen here: https://www.dropbox.com/s/l32kpkuokp...0test.mp4?dl=0
I do realize that it is not recommended to run the SG disconnected, don’t intend to do it if not necessary
As mentioned in earlier posts, I have matched resistors & transistors in my circuit and tuned my SG with a variable resistor, which is still in there.
#3b Amperage in radiant mode
I think I got a bit confused by the DVDs when John is mentioning that the output is current less / a 1-Ohm resistor should not heat up.
Although voltage peaks are very narrow/short, when the frequency is high enough the momentary current that is accompanied by it will heat up the resistor eventually. I remember reading statements somewhere that putting an amperage meter on the output side would not correctly indicate the amperage. My question is: why not? If a amperage meter can be hooked up on the input side, giving an amperage reading of the pulses drawn from the primary battery, why can I not do the same on the output side?
Thanks for your time.
Best regards,
Rodolphe
P.S. still building the capacitor dump circuit, if I have it up and running I’ll post on the other forum thread where we’re talking about that circuit.

#1 Ah vs Wh / COP
My SSG running in generator (common ground) mode will consistently get an electrical COP over 1 in amp hours. However, if you take voltage into account and compare the watt hours, it comes out a little under a COP of 1.
I understand the Ah COP calculation of 1.25 you make (not including mechanical work). However, you say that if you compare Wh, you end up under a COP of 1.
I would say that it is the COP over 1 for the Wh (or actually work done / Joules) that we’re after and the Ah COP is not so interesting.

Did I make a mistake in my calculation?
#2 Swapping primary / secondary battery
When I repeatedly swap the batteries back and forth, it takes a little longer each cycle to recharge the charge battery.
When in post #217 I referred to John saying “you run them both down” (when swapping primary and secondary), I did not mean that both batteries would be damaged, but that you empty them both out eventually. Now this seems in line with what you state in the above mentioned quote.

#3b Amperage in radiant mode
There is a small amount of current along with the radiant spike and also there is an electric field around the conductor that the sniffer coil can detect.
Although voltage peaks are very narrow/short, when the frequency is high enough the momentary current that is accompanied by it will heat up the resistor eventually. I remember reading statements somewhere that putting an amperage meter on the output side would not correctly indicate the amperage. My question is: why not?
