Great to see the improvement and the project coming along. I got side tracked looking at pancake coils but will try and start winding coils for a ZFM tomorrow. Another thing one can see in your data, if kinetic energy is equal to 1/2mV2, in widening the pulse length power consumption increased less than 2 fold while kinetic energy increased more than four fold, so the wide pulse length clearly seems more efficient and perhaps more than twice so. Possibly another reason John had mentioned that this machine isn't a generator, the coil is on and saturated for a great deal of time for any spike, that and the spike somehow with the ZFM set-up and air core behaves "backwards". Don't understand but just saw that when I rectified off the air coil ZFM spike the rotor was dragged. This would also imply to me that unlike the SSG, the spike in an air coil ZFM is likely part of what is driving the rotor. Want another mystery, why haven't you fried all your transistors? I'm not being a wise guy, I have no idea and I have also never built a large powered SSG, but you were drawing 9 watts through two trannys so 4.5 watts per tranny and the spike wasn't shunted to any load or neon bulb etc. Again I'm not expert here so maybe someone who is will chime in, but I would think 3055's would not be at all expected to survive that.
