Itsu:
I find that tuning the kacher or grenade using ferrite, increases overheating when using 24v inputs. So, may not be a good final option.
I also notice that the closer tuning to best output at resonance, the more the coils and components heat up.
Overheating is one of the main drawback of this type of device. Maybe that's why nobody has shown it running their house.
My unloaded grenade output at the rectifier can get close to 1000 volts. Remember that everything changes when the ground line is connected, and it becomes part of the device. I had understood that tuning should be performed including the tuned ground line connection. Geo's device won't even fire up without the ground connection. Mine does not like it either, just won't sync right.
It's curious, but Ruslan has never shown any ringing at all, ever. Makes me think that something may not be right, as there is no ringing even when he places his hand on the grenade coils. So...what's up with that? Could he be faking it? I would not put that past him.

Nick,
I use the ferrite to tune the kacher secondary only temporary, once i know what is the right frequency i will try to make one without the ferrite.
Yes, heat seems a problem, but that should be manageable once we have reached 5kW output, which is more than enough for some cooling.
Concerning the ground, yes that also is a problem as there are grounds and grounds, but there are claims that even without any ground the device should work, only less efficient.
Not sure what you mean by ringing, ringing where?
Anyway, a fake may still be possible, but if we do nothing we surely have nothing, so we can only try.
