This thread is where I am posting my 20 run ssg results and supporting documents. Please find the attached photos. My "experimentor's Journal" and my "20 run spreadsheet" will follow shortly, as my final charging/discharging cycle will be completed later today.

Hi James,

That's a pretty good report, thanks for posting it. There is undeniable proof that when you build it right, it works!

No problem with letting the charge battery go above 14.5v, in fact that is where most of the desulfation occurs. What you reported is perfectly normal for this technology, when you saw the voltage jump around a bit it is because as the sulfation is broken down, the battery's impedance changes and so does the voltage change as well.

Thank you John...it was an awesome experience!

So what's next? I would seriously like to build something big...similar to J.B.'s 10 coiler...or at least something that could grow into something bigger (I have certain goals I must stick by). I do have questions about how to get the biggest bang for one's buck in regard to wire size, and the frugal use of transistors (heavy duty ones powering more than one coil strand, like 3 transistors, powering a 6 wire coil with a trigger, etc) for my next build.

Hi James,

I would recommend you wind a multi-strand coil and build a multi-transistor circuit. You can still use the same frame and rotor. A good place to start would be a 5-filar coil 125' of AWG#18. 1 strand is used for the trigger and the other 4 each go to a single transistor.

Hi John

That sounds good. Plus, I will be working on designing an expandable multi-coil-multi-rotor unit, per my long term goals. I can probably use the TV degauss coils I have salvaged for the multi-filer, but will be using fresh magnet wire for the bigger project...sound good to you??? Questions: I take it that it isn't in good form to put two or more coil strands on one transistor...am I correct? Or, is that something one can consider? And, if so, would I be correct in assuming one would see a greater chance of a transistor failing if they did such a thing?

fantastic spreadsheet. thank you for sharing it.
