what about a coil inside a copper tube? let the tube be longer than the coil.. the tube acts as a short circuited turn … If you now add a coil outside the tube in which direction will be the current?

I made new tests today

Now the configuration is 120 turns on the primary

220 turns secondary

22 turns non dissipative snubber coil

22 turns feed back input coil

I added a 1kohm resistor as a load

The resistor get very hot. the voltage peaks at the resistor seem to be 50v

I think that now is important to get impedance matching to be able to extract energy from the coil…

this is the wave form of the load

(http://www.ionizationx.com/index.php?action=dlattach;topic=2817.0;attach=13241;image)

The voltage input is 45 volts

current less than 2 amps is my guess since the fuse didn't blew up however the snubber winding sends the energy back before the fuse so probably is consuming less amps i don't have a good a meter tehre lot of induction and my clamp \meter don't work properly ./

The only component that gets hot is the primary and a resistor in the snubber circuit that can be plucked off

This makes this non dissipative snubber winding circuit very satisfactory...

I'm not being able to determine if its overunity or not but i'm going to be able to determine the action of the feedback

The one thing i see that makes it hard to quantify power consumption and generation is the complex wave forms.. like in your picture.. you show a spike of 300v that decays to 200v and so on...
its not so simple to calculate the total watt seconds from a wave like that..
Need some good ole calculus!

i agree is not a very nice waveform to calculate

but i guess we can say that around 25w was constantly dissipated from the resistor from this graphs

not sure how your getting 25 watts.. sounds like a very crude guesstimate

yes is an approximation

I hopping to get a wattmetter

  • let the voltage do the work

why not estimate heating power? if  the water is insulated and little volume it's a close approximation
