I've been gearing up (as I know Slider and others have also) to test the Gegene. Despite packing and moving, I'm carving out time to pursue this study along with the slayer-exciter circuit and others.
Gosh this is fun! it really gets me going.

Thanks for that, wings. Is this fellow-researcher in Russia? clever fellow...
I liked the way he removed the coil from the stove, then placed BPCoils on either side of it.
Also, nice test with the metal disk in the glass bowl + water. Wish he had measured the temp rise, then compared the Qheating (KJ, convert to KW-h) with Energy input (KW-h). I can do that... ;)
I've been thinking more about this today. To test the Gegene , it seems desirable to use calorimetery, i.e., to HEAT WATER and measure the temp rise. This I noted above, and in numerous posts, as have others.
So Naudin takes a BPC with current induced from the cooker, then runs that through a resistor in water to heat the water -- thus, heating water via an indirect path.
The vid-maker (Russian) simply puts a disk presumably ferro-magnetic in a glass dish holding water and heats the water semi-directly. No wires. Clever.
But
then the next step IMHO would be to add some salts (ferro-magnetic??) to water in a glass or plastic bowl, and heat that solution DIRECTLY over the induction cooker. BUT -- does the additive have to be ferro-magnetic for the anomalous- heating effect (AHE) to occur?
Does regular heating with the induction cooker -- same question for AHE -- depend mostly on Eddy currents and electrical resistance, or mostly on hysterisis-effects-heating, or both? probably both.
NOTE: I'm not looking for something potable or edible here -- looking rather for "anomalous heating effects"...
But note with the flat BPC made of copper wire, there is no hysterisis-effect heating in the BPC, just current, similar to eddy-currents in a cooking pot. But the induction heater works much better IIRC if the pot is ferro-magnetic... yet most (like Naudin) are using copper wire...
So now I'm looking for a ferromagnetic salt, that stays ferro-magnetic when dissolved in water... hmmmm...
Lots of avenues to pursue... Your thoughts?
Let me start with a simpler question -- as I'm climbing the learning curve.
As I read about induction cookers, finding that the heating of the pan is from two sources:
1. Induced (Eddy) currents, and resistance in the pan
2. Hysteresis losses, hence the "requirement" for a ferro-magnetic pan. Some steel pans do not work well because of this (IIRC).
My question -- I assume a pancake coil picks up energy only by (1), and the needed resistance is in the load -- since copper is not ferro-magnetic. So, is "ferro-magnetic" not required?
