Kapanadze Cousin - DALLY FREE ENERGY

Hi Itsu
Do you remember the value of cap that you connected between drain and source which leaded at the half of the ringing frequency? (At my setup i had a 1.35MHz ringing and i used a 2.2nF to bring it down at almost the half. So my parasitic capacitance calculated at 2,2/3=733pF

Hi Jeg,


yes, i found 3nF caused the ringing to get halfed (from 1.43MHz to about 700KHz), so my parasitic capacitance was calculated at 3/3=1nF.
The final capacitor should be between 4 and 10 times this, so i settled for 6nF (2x 3nF parallel).

About frequency multiplier and Tesla coil - you can force it to work as normal high frequency transformer. The ferrite filter choke between TT and top load have to chop sine wave into spikes anyway. It will be not so efficient as in natural frequency but still will do a job.
About Ruslan explanation - I mentioned before about low resistance resistor so you can get on which frequency it wants to run for maximum current over resistor.
Now from Roman(akula) private conversation 2 days ago - the way he understands grenade coil the equivalent is choke with capacitor in series. The bucking coil make capacitor function within. The external electric field is charging them like 3 plate capacitor where 3rd plate is TT top load. All you have to do is to sum all energy within grenade coil which got strong magnetic component with strong electric field from TT  in resonance then you can extract more energy than you put into grenade coil.
And when clarifying bits with Roman we talked same language so we' RE on same track. He loved idea about frequency multiplier so his part of the deal was to give me explanation how he see fundamentals working in device.

Cheers!

hi T-1000,

To a certain extend yes this kapandaze coil behave like a tuned capacitor and choke/inductor combination.No doubt about that.That was the easy part.

The part which was not easy to understand-
{ All you have to do is to sum all energy within grenade coil which got strong magnetic component with strong electric field from TT  in resonance then you can extract more energy than you put into grenade coil. }

As what DragonLord mentioned in his theories in forum which he lingers-Tesla coil is estimate 95%electric field and 5% magnetic field.

Question to you is -

Some of us including myself do own a spectrum Analyzer.May i ask how do we identify those "strong magnetic component" from the grenade coil.
I do know there are some funny looking harmonics which keeps going up and down constantly.

Remember the forum started with PWM and then later part started using ferrite rod to meddle with the tesla coil frequency.So naturally we have scan the frequency from few khz to around 37khz.

To date only hoppy and myself got a funny result which cause the bulb to flicker which is obvious to the naked eyes provided if tuning is done right.
Nothing unusual to report from the old typical tesla coil setup.I have also replicate effect similar to URFA as well.


----------------------------------
Base on one of the test related to BEMF from Tesla Transponder coil setup of mine.By connecting 1 turn or few turns from toroid blue or nano crystalline which the Earth(water pipe) wire pass through revealed only 22volts for single turn and for few turns gave me nearly 50volts which i had to disconnect capacitor.

But in both scenarios the 2 different setup charge <1000uf 50volts capacitor slowly.In other words this BEMF recovery won't work if i try to recover from Earth wire.

One more plan is available to recover BEMF not from grenade coil.Only time can tell.

Magpwr,

The replication in my side is in progress and it will take few weeks until all electronics will be in device. Then I will start with tuning and will see how it goes. I can always reach out akula and hopefully find answers in the process.
Then will see if the understanding I got is correct.

Cheers!

Hi T1000
I think that even at normal high frequency transformers you can not avoid tuning. But definitely your idea worth to try!

Let me ask you something more. How will you overcome the fact that Grenade doesn't give peaks at any high frequency?
It has each own inductance, capacitance, and specific length which give a good rise only to one frequency and some of its harmonics which belong to the same set of frequencies (associated to wavelength). If your low frequency will move, and a change of  high frequency will follow (according to the given relation 1:100 for example), then your high frequency emission will move out of the right set of frequencies. You can't force easily grenade to oscillate at any high frequency. What are your thoughts about that?

Thanks Itsu. Just comparing our results. I think i made a mistake with my resistance calculation. It gave me a 20 Ohm value which looks less than optimum and i feel heat across it. I connected the diode in parallel to the resistance as in Acula's snubber and i noticed less heat. It seems that the diode in parallel reliefs it a little. With diode in a direction as in Acula's snubber, when mosfet stops conducting, all the current needed for snubber's capacitor charging, passes through diode's branch and not through the resistance. I have to recalculate it though.
