Self-Runner NS Coil Pulse Motor Live Video Stream. It's been going for months!

I am sure if we review Laser's vids, he probably mentions exactly what he used...I just do not recall at this time.

From the video:

Soft Iron Core Rod from Sargent-Welch 13mm x 150mm

Plastic spool ends - not wood

20 awg Galvanized steel wire (not iron wire) from Lowes Harware store

.9mm (19 awg) cotton covered copper wire from http:\\wire.co.uk

He covered the soft iron core rod with electrical tape not cotton

A dielectric is not a conductor but is a holding place for electrostatic fields. Just like a capacitor. If the current is low enough and the electrostatic flux is not stopped, then the electrostatic field can store charge in the cotton. If the cotton field,I like that!, has too much water whos dielectric is 80.4 it stops the charge. Before you put the coil in the ground take meter readings. Analog meters or galvanometer are best suited from my understanding from other experimenters. Leave the coil in the ground for a week,month whatever and leave the coil unconnected to a load which includes a meter. In other words keep the circuit open. I would think there would be a charge buildup in the cotton. Externally you should be able to check it faster with a pulse generator or maybe a cap. What I dont know for certain is if the circuit should be closed or open in order to pick up a charge. Both need to be tried. It would be nice to have the equipment to vary the voltage and current to create a baseline if indeed it would work. Maybe using a cap with some type of pulse circuit would work.

I don't understand what this means: "Laser used a salt solution to rust off the galvanized iron."   Did he do this to the wire to make it bare iron wire?

Not likely. The Zinc wouldnt have much of an effect if any on the magnetic field of the iron. He was probably looking for a galvanic response and if there was an increase in voltage or amps. He accelerated the galvanic action with the salt which created the iron oxides on the surface. Internally the process should be slower as its not exposed to air. Zinc coatings can slow galvanic action. As stated previously if the current is sufficient it will stop or slow down the galvanic action. This type of process is used on boats.

Thanks for the explanation Iota.

Laser, I hope we'll see more of that last construct with multiple miniature coils.  How's it going with this?

I'm afraid to report I've done absolutely nothing yet.  Time a bit constrained.  But I'll try again at the weekend.  I have written off to chemists to see if I can rally some interest.  Fingers crossed.

Regards,
Rosemary

added BTW Nice to see you join the discussion JamesThomas.  In my defense, what I lack in maturity I make up for in chronological age.  But somehow I think I lose out on both sides of that argument.  LOL

I bought some 20 awg Galvanized bare steel wire from Lowes like LaserSaber used.
I have a ferrite rod 7.5" L x 1/2" D.
I have 18 awg magnetic copper wire

First I wrapped the ferrite rod with cotton.
Second I bifilar wrapped one layer with 73 turns of 20 awg Gal. steel wire and 18 awg copper magnetic wire.

The steel wire is negative and the copper wire is positive.

Dry:
2.5mV connected to steel and copper
If I connect to both steel wires or both copper wires then I get zero volts  as expected.
steel wire 1.3 ohm
copper wire .5 ohm
Forgot to measure inductance when dry. 

Wet:
Inductance: steel 518.9uH, copper 493.4uH
Voltage:
.510V at first but dropped to .364V after 2 minutes
then it went back up to .375V 5 minutes later.

Wet again 20 mins later:
.382V
.457V 2 mins later
.462V 2 mins later
.415V 15 mins later

During this whole time my digital meter was connected, which was a drain on the Earth Battery I know and I didn't add water so it was drying out also.

Unconnected digital meter at .411V for 5 mins.
Reconnected digital meter and it read .523V then started dropping.
2 mins later it was down to a low of .462V and started rising.
2 mins later it was up to .368V all the while my digital meter was connected.

If I disconnect the meter for a couple seconds and reconnect it the reading jumps to .526 then falls.  I did this 5 times with the same results.

After 10 mins I connected my meter and got a reading of .502V before it started dropping.  So as it drys it appears the voltage gets lower.

Another test would be to wet the coil and wrap it in plastic so as not to be able to dry out very easily.

I'll recheck it tomorrow morning in 8 hrs.

So I need a circuit which connects then disconnects a small load (resistor) every 2 seconds to see how long this Earth battery can run.
Any ideas??

I need to get another analog meter also.

Don:

If you used mag wire for the copper, you need to strip the plastic coating off of it.  Or burn it off.  I used naked copper wire.

Interesting results.
