@hans: it's better than reading a good novel!  The coil part is certainly the key, and determining what is happening.

We should build a few of these devices and set up a testing procedure.  Would be good to have people in different parts of the world participate so we can see how the earth's magnetic field influences the devices. Either everyone should build exactly the same device or we should  come up with a bunch of configurations and let one person try each one to save time.   Different wire gauges, different number of turns on primary & secondary obviously make a big difference in the results obtained.  Do people agree that with some experimental results we may be able to get a better picture of what's going on?

Is your led is still up?  I have put 1.5" diameter copper tube about 12" into ground and 1.75" aluminum tube at the same depth 4 feet apart. All I've got was .745VDC and  .101 mA.

@LocalJoe
First, thanks for bringing this topic up.  I really enjoy it.  Can you suggest how to wind the coil?  Thanks to Hans I know it is wound on soft iron core like transformer.  Primary both copper and iron wire insulated are they going together or one on top of the other.  What wire gauge to use on primary what on secondary?  you can give me please different specs what yours going to be then we can compare results.  Thanks, George

The iron wire has to be exposed but not touch it self so side by side would be the answer your looking for.  As well somewhere it said the larger the capacitor you have the easier it flows so a big cap for the initial experiments may be very fruitful. Like the big blue tin can looking ones that folks use for large storage low voltage. Just a thought.

G'day all,

The way I read it it is irrelevant if the iron wire is bare or encased in some insulating material. According to the patent it is also irrelevant how many windings there are.

What would appear to be important is that the iron wire or the copper wire for that matter do not come into contact with each other or the core.

Stubblefield seems to be certain on that, or he was just hedging his bets against usurpers of his patent. Only experiment will show.

@ Localjoe:

Thanks for the compliment on the video.  It was hurried and a little crude with a few mistakes but, I wanted to get the info out there.  I will look into your resistor idea.  Thanks again for posting this topic.  Very exciting.

@ George:

Yes, it is.  And the cap is fully charged and will light it on its own also.  With your experiment, according to the galvanic chart published here earlier by me, you should have read .85 vdc just by the metal difference.  I have always been able to better that galvanic number by a good percentage, and you should too.  First, were your electrodes set up so the copper was to the north and the aluminum to the south aligned on the north/south meridian?  (NOT) the magnetic north, depending on your location it will be different.  I have found this makes a difference which is very measurable.  What Localjoe suggested in the very begining, which I did, was to plant your most positive metal to the north (in your case, the copper) and then, probe around along the n/s alignment a few inches deep to obtain the true polar north south by using the area that shows the highest readings.  Then, sink your aluminum rod there.  I'll bet you find a big improvement by doing this.  Also, by reading the articles posted on this thread, I read that the south post/pole should be not as deep as the one to the north.  By experimenting with these parameters, you should be easily able to exceed the galvanic chart's numbers.  I have in the past but with my current setup, I am only in the ground 2" with the magnesium block so I know I am giving up something there.  Still looking for a mag rod of some decent length.  Best of luck.

@ Hans:

I am greatly enjoying reading your posts.  This is like a treasure hunt where we have a few pieces of a map, and need to fill in the rest.  It should be fun.  Thanks for your efforts here.
