Kapanadze Cousin - DALLY FREE ENERGY

  Tektron and All:
  I spent some time today to install the new 18v, 5watt zener diodes, and re-solder most all of the Mazilli circuit connection. Unfortunately, it did not help to cure the mosfet overheating issue. I tried the circuit with a single 150 watt flood light, also just a single 100 watt bulb, as well as with just a single 50 watt bulb, by itself. But, the fets are still untouchable only after 10 seconds running.  Sh!t.  Oh well, back to see what I can do about it...
  Tek: Thanks again for your help with this. At least I know now what is not the problem.

  I'm still working on the Akula air coils. I've taken it as far as I can, but I'll need to obtain some more wire for the output coils. As it  takes alot of turns.
  I'm still intrigued by this second Akula video circuit. I don't see how to get the power for it the way that he has it laid out. Especially if I try to obtain enough output from the 3 turn yoke coil, just won't work that way for me. So, I'll try it a different way. Of course, he is running his on 24v, not 12v, like I am.
  I'll post some pics soon.

  I see that Geo removed all his videos from you tube. I was hoping that he would give us a hand (pics and videos) with his self runner circuit, as he had mentioned. But, I guess not...

The zeners in this circuit are gate protection zeners. With 12 volts drive they are hardly necessary at all, and that is why you have noticed no difference from installing them.
Your transistors are overheating not because of too much gate drive, but probably because of one or more of these reasons:
1. not switching at zero crossings. Check symmetry of the crossover diodes and make sure they are working properly at the frequency of your oscillator. I use 1n4148/1n914 diodes which are working well in 12 volt versions. Choke, current paths, high-resistance solder joins all affect the zero-crossing symmetry. If you had an oscilloscope this problem would be easier to diagnose.
2. One mosfet carrying all the load. These circuits can actually oscillate with only one mosfet actually working fully. This will also produce heating but the one working harder will be hotter than its slacking partner.
3. Insufficient gate drive. Not likely here.
4. Continuous avalanching; this is, I think, the most likely culprit here.

@magpwr: Voltage rise in a transmission line is something that designers usually avoid. Your configuration maximizes what they try to avoid: VRSWR. You are most certainly NOT developing more energy than you are supplying with your power supply, no matter how high your voltage and reflecting currents are. This is the same issue that burns out final RF output transistors in, for example, CB radios operated with high SWR antenna configurations.

Don't forget: If you have an electrical input-output device with a TRUE COP of > 1.3 to 1, I or any other competent electrical engineer can make it self-loop. Guaranteed.  On the other hand, if it cannot be made to self loop, then the high COP is an illusion, derived from the usual culprit: mismeasurement of actual power, usually by not taking into account the reactive power and the voltage rise by standing wave resonance.

Hi tinselkoala,

To be honest i have not expected the longitudinal experiment which i started  to merely replicate as what was shown in video.But to my surprise it is able to destroy bulb filament total rated at 500watt using low power at 40watt.If it was typical leds for output then your theory would be right.In layman term we all know high voltage stepped up would means low current at the output.But the same did not apply for longitudinal wave experiment.It does defy logic even for me.I am getting some high end capacitors for this experiment.

I will provide outcome for this experiment after 1 month after receiving components.In the meantime lets assume you are right for the time being.

Nick,

I mentioned way back that the zeners are for protecting the mosfet gates when and if you increase rail voltage up to and above 24V. Did you check your two crossover diodes like I suggested?

Geo has probably at last realised that he does not have a self-runner.
