To All,
Over the last several years, I have spent considerable time, effort, and money experimenting in pursuit of Don Smith's elusive overunity device(s). I have learned a great deal on the journey and I believe the time is right for me to give back to this forum where I learned so much critical information, without which I would not be as far along as I am today.
Here are the important things you need to know:
The L1/L2 coils arrangement, either step up or step down, is not critical. Study Don's "commercial model" device for how he did things without coils. You can make it work with the coils but it creates needless complication and expense. The relative length of the L1/L2 coils is also not critical, although if you pay attention to the 1/4 length rule apparently you don't need caps. It seems to work just as well if you just use the right caps for L1 and L2 to get their respective LC resonant frequencies equal.
I am currently having the best results charging caps without the coils by going from the HV terminal of the flyback directly to one AC terminal of a diode bridge. The other AC terminal is connected to earth ground, and the DC terminals are connected to the cap bank. To understand why and how this works, think of the diode bridge as two back-to-back Avramenko plugs instead of a regular rectifier bridge. It rectifies the longitudinal wave component of the flyback HV/HF output and uses electrons supplied by the earth ground to actually fill the caps. Charging is somewhat enhanced by connecting the third terminal of the caps (outer case) to earth ground. Yes, you need fast diodes. The high speed, high voltage diodes made for inverter-style microwave ovens seem to work well and are cheap enough on ebay.
Using a GDT (gas discharge tube) on the cap bank at this stage produces a very nice cold blue spark. The GDT barely heats at all even after extended running. Hmm, maybe there is something different about energy gathered this way?
The final step is to discharge the cap bank into a Plauson converter (see the Plauson patent for details) to convert the "cold" electricity in the cap bank back into regular hot electricity. The real trick to this is to size the cap bank and the GDT or spark gap trigger voltage so that it gives exactly one spark per oscillation at the resonant frequency of the output transformer. I have tried using caps to lower the LC resonance of the output transformer and this doesn't work well, it basically has to be the natural resonant frequency. To attain realistic values this means very large inductances and explains Don's love of Metglas. I'll let you know when I have some. I can get very nice ringing waveforms with every spark but to work well and produce useful power the spark needs to happen every cycle, perhaps 50 or 60 Hz if that's what you're aiming for. With a 400 nF cap bank and 400V GDT I get sparks around this frequency.
One of the things I have struggled with from the very beginning with the Don Smith device is to understand exactly at what point does the overunity magic enter the system? Is it the L2 coil? Is it the cap bank? In a running device, where does it actually appear? If any of the very select group of people who have a working device that shows overunity care to answer this question, I would appreciate it, but I think I now know the answer. It's in the output transformer (Don's "isolation transformer"). It's possible that the cap bank charging using longitudinal wave energy and ground electrons is overunity if done right, but in my arrangement I don't see any noticeable power gain at that stage. This is good news for all those experimenters who got that far with the device and were able to tune their coils to get power through and charge the caps. IT IS NOT EXPECTED TO SEE POWER GAIN AT THIS POINT. WHAT IS IMPORTANT IS THE KIND OF ENERGY THE CAPS ARE CHARGED WITH. The magic happens in the output transformer and only at resonance.
So if you are one of the many who experimented with this device but gave up because you never saw overunity, I suspect you gave up too soon. You didn't build the output circuit. Go back and finish the job.
I will leave you for now with this final tip, something else I have learned along the journey. Has anyone else thought to try WEIGHING your cap bank? Hmmm...... Maybe you should try that! Post your results in this thread. I will go into more detail on this at another time, but for starters refer to the diagram on page 40 of Ken Wheeler's "Uncovering the Missing Secrets of Magnetism" book. There are 4 quadrants, electricity and magnetism, dielectricity and gravitation. Moving charges create magnetism. Moving dielectricity (LMD/longitudinal wave energy) creates what? Try it and see.
