Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

@all

I have to remove two protruding axles, and cut off other larger sections, all necessary to get this Stubblefield winder going.

1641 = the offending item to be cut off
1642 = made a start, almost done
1643 = Done, offending item removed
1644 = Getting ready to remove one of the old end supports
1645 = Done, time 4 a cuppa T 

I was up untill the weeee small hours of the morning, Im tired so I'm calling it a early night
Catch you all tomorra

I have an internet friend who is a sculptor. From time to time he sends out links to his list. Today was a whopper.
This is the write-up from live leak.

From the exhibition Sculpture in Motion at the Atlanta Botanical Garden on view through October 2008 and curated by Brigitte Micmacker from Sculpturesite Gallery. Courtesy the Curator's commentary: "Morpho Tower, Sachiko Kodama's mesmerizing synthesis of science, technology and art rises like an eccentric, thorny, botanical form within a world of most peculiar botanical forms housed in the Desert  House of the Fuqua Conservatory.
Employing electromagnets and magnetically-charged microfine particles suspended in oil set in motion through a computer controller, Kodama, who is associate professor at Tokyo's University of Electro-Communications, explores an entirely new territory where the seductive glossy black liquid seems to turn into rows of solid spikes impeccably organized around a spiraling cone, only to dissolve abruptly into obvious liquidity once again --a rhythmic flow and ebb, an alchemic dance where the artist playfully communicates basic principles of physics without elucidating them."

and here are 2 videos of the sculpture.
yer gonna luvit!

wow a great demo of magnetism in motion!

I have a technical question relating to the production of DC from a big transformer.
This question I am directly asking mw383 and tishatang for their responce.
but others may answer if they so wish.

Here is my problem.
I have a NiCAD battery bank setup on my side verrandah, it consists of 20 ALCAD MP 300 individual 1.2 volt cells
I have a old Lead Acid battery discharge tester which is designed for the 2 volt wet cells, not these 1.2 volt cells, but it can still give the Ni-CAD cells a workout.

These I want to drive my UPS which powers my PC and a range of other stuff.

A couple of these cells are rather low in output, although they do come up with a good recharge, but they don't hold their charge as long as the other cells.

What I think they need is a single or a couple of BOOST charges to get them going properly again, but I currently don't have a DC rectifier that is capable of handling the punishment I want to meat out to then for about 1 hour or more.
-----------------------

OK, I have a MOT where I have modified the Secondary output, I removed the original secondary winding and rewound it with 4 loops of the usual size lead that runs from the car battery down to the starter motor.
Now I have avaliable hundreds of amps avaliable, at 4 volts, but this is AC, not DC

Here is what I suggest to alter the AC output to a DC output, I have not tried this, but it stands to reason it will work.

If I place a heavy diode on one leg of the 240 volt input to the primary side of the MOT, would I get DC out, by driving the primary with DC pulces.
It would have to be of sufficient wattage to be able to drive the primary coil. What size should I use?



My thinking is, as the AC drives the MOT, the secondary reflects the AC sine wave in the output of the secondary coil.
So we get the same sine wave on the output of the secondary, albeit the voltage is much lower but the AMPs are much much higher.

Now, if the MOT primary was fed only the top half of the 240v AC, then the output of the secondary would reflect it's output as the same, so would only the top half of the sine wave be presented, and would the AMPs reflect this also.

If this is so, would this be a way I could get hundreds of DC amps without using a ultra heavy duty diode on the output of the MOTs secondary coils.

I think a stream of DC pulces will be able to really give the offending cells a bit of a workout and perhapse recover them back to a resonable capacity, or at least recover the cell somewhat.

Now, the AC here is 50 cycles, so if I place a diode on the imput, I should get 25 pulces in and 25 pulces out.

@electricme
My quick answer is that it will not work.  An inductor will kick back what you put in just like a capacitor.  Even though you pulse the primary, as soon as the pulse stops, the inductor will push back the current you put in.  The secondary will see a distorted AC input signal.  The secondary will tend to smooth it out even more.  The end result will be AC.  You will need the heavy duty diode on the output.

There may be another way to condition the weak cells by radiant conditioning using a Bedini type charger?  Use the search function on this forum and search conditioning batteries, or reconditioning batteries or something like that.  Somewhere I have an article or link.  I will look for it.

Here is a schematic of a radiant charger.  Unfortunately I don't know where I found it?  It may not work for nicad?  However, in my readings, some posts indicate success with nicad batteries.  Research it before trying on your batteries.  Otherwise find a heavy duty diode.
