Warren good point, about the eddy current.
Oh way back you wrote about grounding a solar system....I like to keep mine floating but have ground wire surrounding panels to collect static.My home wiring is left as is with neutral grounded at many points through appliances.I found it impossible to get it all floating.I recommend using a isolation Tx on your inverter to home wiring so you inverter and batterys won't become hot!
My cable internet uses a ground and needs 12 volts DC for the modem from my solar DC and caused havoc without the isolation.

DaveThe eddy currents in a brass core will get it hot, I would expect.Cheers Warren

air coils don't saturate right?

James! During my many years of hands on Electrical Contracting and Researching electrical phenomenon, my first real brush with the Neutral Spike was while designing small electric motors in 1981. This was a tall stack shaded pole motor that was designed to be reversible by switching the position (electrically) of the capacitor in series with the start windings via double pole/ double throw reversing switch. This new prototype motor was MFG in Chine and test samples were shipped to me for QC testing. Destructive testing included the reversal of the motor while running full speed forward via switching the reversal switch! When switched the double throw switch literally exploded with a loud WOOOMP! and a bright green flash. (vaporized copper). I had a double EE Professor from UT Arlington come over and observe the phenomenon. since the whole 1/6th HP motor was being run off 18ga. zip cord with earth bond ground wire to motor frame, it was quit bizarre to see a 30 amp rated switch just explode. His calculations could not explain where the burst of energy came from. After welding the contacts of several heavy duty reversing contactors and examination of the original motor schematic with the wiring as received from China ,I found that the little lady in tennis shoes (assembly line Chinese lady) had placed the reversing circuit and switch on the neutral side of the line input. In effect (when in transit) the entire motor electric circuitry was in an isolated state (floating neutral) condition which is a great big NO, NO, This set up the perfect scenario for the neutral spike from earth ground to occur. I have written all this up several times before for this EVGRAY site. Most people do not understand how shaded pole motors work much less how you reverse their rotation. You have to reverse the rotating magnet field by phase angle 90 degree leading or 90 degree lagging (start windings) relative to the main run windings.

Just my opinion but that looper might be a version of the pulse led out research .a Chinese guy mad a wheel and found that if you pulsed once you get three back .the heavy fly wheel would absorb the kinetic energy from the pluse and run the DC generator .the board would control the pulse timing .a1000 watt pulse would return 3000 watts in kinetic energy .spread that energy around the pancake motor coils to reduce general over loading of a single .point .but the Chinese version doesn't use iron cores .this is a lot like bedini's first self runner but he adjusted it for one battery .and ran for 15 years .what if he adjusted it for ten ?

Norm, How many different setups did you use in your formal investigation of the neutral spike, I know about the locked rotor motor but were there others?
There seems to be some crossover with Don Smiths claims of aluminum and copper used as opposing capacitor plates and the work of the builder of the Swiss Testatika machine.
What if any interesting observations have you made in re to the copper/aluminum function?

Mick! I was the first on this site to bring up the Evenescent wave &
critical angle for it was in my research on a zero loss solar heat
collector. This tied in directly to MBKIng work on the plasmoid
experiments.
