I need help here. With your skills I would love to "know" why I have those spikes. Do you? There is nothing special on the circuit or the output circuit. Just magnets passing by a coil with bias magnets behind. One should NEVER have those spikes there, correct?

Now it would be a great moment for us to speculate what could be the reason behind those spikes and ways to test the hypothesis speculated. I still have the motor so good timing now.

@plengo,
you could try to isolate the origin of the spikes. A suggestion would be, to measure the voltage at both coils simultaneous, by putting the grounds of the probes to the middle point of the coils and the A and B channels to each output end. Then it's possible to see if it's one of the coils, or both, that makes the spike. If you then invert one of the channels and add both channels you will get the signal as measured with one probe only.

Have you made a test to see if the cores becomes saturated when the magnets gets close? If they do you get Ferro resonance. Then the inductance is decreased and the nonlinearity can make the system resonate at lots of different frequencies. This is probably also the source of extra energy output as it is a negative inductance characteristic. Just as in a refrigerator, but with fields instead of a gas/liquid, this will decrease the entropy.

good call on the antenna possibility, neptune!

i'm not sure if the following info has been posted before wrt the MD design...

you might be interested to take a look at the details about the Alexanderson Alternator on Wikipedia

it was a motor generator used to create some of the first AM radio transmissions

it's a reluctance motor-gen, with high number of stator poles, and  a slotted rotor disc (instead of mags) which 'chop' the reluctance of pairs of stator coils as the slots pass between the stator coils

the output was formed by paralleling up all the stator o/ps (sound familiar yet?)

iirc max speed was approx 20,000 RPM and the transmitted frequency was given by RPM * No. stator pairs (so high-end LW, low-end MW bands)

apparently there is still one system operational, in Sweden, which is turned on for an anniversary  transmission (Alexanderson's birthday?)


hmmm - maybe Romero was just picking up a radio transmission from his device's soulmate! 


this has been a public-service announcement on behalf of the Swedish Broadcasting Corporation

Lol!  Excellent post!  You had me going right up to your final line and then I LAUGHED!.

Thanks for that. 

Everything in your post is really interesting.  Do you have an references to this that I can read?

Thanks again!

PS.  I too have considered the possibility that I have only an RF receiver.  I guess testing will tell.

OK Mo , yes I am A Brit  , East coast of England . Being retired I sometimes keep odd hours . Why I am I surprised by the very high frequencies . Read Nul-points post about the Alexanderson Altenator . This was a mechanical device , state of the art at the time  to produce Radio frequency power . Running at 20,000 RPM , the best it could manage was about 1Mhz [one million cycles per second .]  According to my theory you are producing 375 Mhz ! So things are not adding up . We desperately need input here from someone who has more knowledge than I do . It is important to remember that I am just a retired Truck Driver . But I will always help if I can .

It will not be easy to get exact readings as the proximity of your hands and body will effect the results .

No shit!  I hold down the "antenna wire" (insulated magnet wire) with my bare foot each time if cut the antenna wire shorter.  And the shorter the antenna wire becomes, the more I can "hear" this feedback from the rotor. 

Every time I step on the antenna wire: The rotor slows down.

What is the expected frequency band of ZPE?  (Trust me, I DON'T KNOW!)

Been a few years since I was back in England.  Beautiful country if not for the rain (and rain, and rain).  But the rain I remember from my last visit might have only been due to the time of year or just a weather pattern.

As a child I remember feeding pigeons in a park in London.  I forget the name of that park right now.

But it never rained.
