Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

@ Joe:

Thanks for the clarification.  That is what I thought we were doing with the exception of the separate battery. What would be the harm in powering the motor and pot circuit with the induction coil primary?  I like the idea of self-contained.  Wait, let me attempt to answer my own question.  If we use 80% of the power generated by the primary to run the motor, we only have 20% left to feed to the secondary via induction and therefore our output will be much less.  Is this correct?

I believe the info on the little hobby motor said you could run it 24/7 for over a month on a single D cell.  That seems pretty good to me.

I have an idea for an easy interrupter disk configuration that would allow for many on/off in a single rotation.  I will attempt yet another crude drawing later.

PS  Thanks for saying the secondary could be insulated, I was not aware of that.  Does it need to be solid or stranded or does it matter?

@ Bill

Yes your right about the power consumption
as far as the secondary its only interacting magnetically so any kind of regular plastic insulated wire is worth a shot.  If you have ever seen a pbx room or phone closet in a business you might recall a bunch of different colored thin copper wires some striped and some solid of the same colors.  The same wire is present inside a cat 5 network cable 8 wires i just used a single wire out of the bundle i had this wire already on a spool it was called hookup wire or something along those lines but anything of a smaller meaning thiner  grade with many turns should work great.

@ Joe:

Thanks for the information.  I should be able to find something suitable.

Here is a crude drawing of an interrupter disk idea.  It can be whatever diameter desired.  I was thinking of using a cd.  You just simply glue (super glue) bare copper wire of suitable dia. in the spoke like layout and then alternately glue some dielectric material in between each "spoke".  The insulating material could be the same size wire as the bare copper but insulated.  This way when the brushes (flared stranded wire ends) come in contact with the copper wire, as it rotates, it will make/break many many times per revolution.  Using your idea for a potentiometer, we would have a wide range of frequencies to play with.  One has to be careful when using super glue on the copper.  This does not conduct so you have to keep it off of the top contact surface, or sand it off later before gluing on the dielectric material.  There are many ways to construct something like this, I just wanted to submit one idea.

[ The two leads from the primary could be presented side by side such that they complete the circuit on the same
  spoke of copper wire. ]

Are you soaking your coil in water? (the sink)  My measurements were taken while the coil was under water.  It continues to put out the same as it dries out, then gets less and less as it does so.
Bill

The sink?

I just put it so the bottom of the bolt touches the stainless steel of the sink. My pipes are black plastic coming and going (Cheap manuf home from 70's). Maybe yours are iron going into the ground? anyway the uA count is rising. slowly but it has not stopped and it reads 29.3ua.
I got a meter from the hardware store that reads amps better than the other. It also does a transistor H_fe check. It still only has a high ac range, but it was $10. much better. This is the first time I can read mamps at all.
It's now 30.8ua

So, what do you read on the table in a jar, for instance?

thank you,
jeanna

@ Jeanna:

I used my bathroom sink.  It is ceramic and I checked, it does not conduct at all.  I have no jars or buckets large enough to fit the entire coil so I used the sink.  The stainless might be shorting something for you possibly.  Maybe not.

It was so funny when my friend was over here.  He had been a tech at IBM for a very long time.  He said that with my leads sticking up out of the water, they were going to short out.  They, of course, did not.  I set the meter for a continuity check and he told me to place the probes into the water.  I did.  No connection at all.  (I did this to prove that the water would not complete the circuit between the test probes) With the coil completely under water and with my friend watching is when I obtained 19mA.  He was astounded.

My pipes are copper and pvc.  No connection to ground from the bathroom sink at all.  Once wet, I can carry it in and lay it on a table and it still keeps putting out, for quite some time too.

Sounds like a great deal on your new meter.  I have seen nothing like it in my area.

Bill               PS  On the table, once wet, it reads between 12 and 14 mA.
