I noticed that Stiffler uses the two diodes like Avramenko, but not the capacitor between the diodes and the load (placed in parallel). Avramenko also used HV, and had a gap across the capacitor.
So, if I understand this correctly, Stiffler is saying that he has a circuit that generates "cold current", this is converted to conventional current by the diodes, then this is fed back to power the circuit.
Where is the mechanism for "gain"?
There would have to be a greater amount of current in the portion of the circuit after the transformer, where the "cold current" starts. So, maybe not all of the cold current is "converted" to light, and enough is left over to power the circuit. hmmm....
In one of his old articles that I saved, he measured a variable currnet of 105mA to 450mA in the ground connection (earthed). He felt this was very interesting at the time. This was back in 2007.
If Stiffler has "gain", why hasn't he scaled this up for a more impressive display?
