mopozco puts out 0.8 - 1V from its big iron bolt and copper tube... and the current its pretty high cause it can power a coil... that runs a motor.

then tell us about your results with aluminium...

I am not sure.
The galvanic difference between iron and copper is only about 0.3v. So the bolt must be zinc coated because that is the right amount for copper to zinc.

---
I myself am not getting so much today.
I made a barber pole like lidmotor's with copper and magnesium, and while I can light a red led from the secondary, it is not producing more than 0.6mA
This says more for my joule thief than it does for this battery.
Maybe I need to sand the copper or something. I am surprised.
It works so much better in the plant than it does in a jar.
I love those plant batteries!

@Jeanna---Slayer and I both got a little better performance from our "Barber Pole" batteries. I wonder why yours is different. Try putting lemon juice or vinegar on it and see what happens. Be ready to rinse it off with tap water when you are done because it will eat the Mg pretty fast otherwise. Both of the ones I built run a JT easily with just plain water.

@ All --- There is a commercial AA battery out now that is an Mg/carbon battery. You can buy them on Ebay. You activate it with almost any water based fluid (you use a little eye dropper that comes with it). The shelf life is 10 years but they only have about a 600mAh rating. It is a Japaneese invention called the "NoPoPo".

Here is a one of several Youtube videos showing it:

an oscillation enhancing cap

@lidmotor,
I suppose since mine is a copper pipe and not a carbon rod, there is a wee bit less voltage.
I cut off a piece of magnesium so I could weigh it first, but I forgot that 30 inches is the best minimum, and I cut off a 20" piece.

---

The advancement I made however is worth it.

I used a calculator and found that there is a resonance with 333khz and 1.6mH (what I have in the secondary of this jtc) with a cap at 140pF.
I didn't have that exactly, but the 151 = 150pF is enough to make a constant light and a good sine wave.
This little cap is across the secondary leads.
So, even though it is only 0.6mA, I am still getting a steady light after 12 hours.

The drawing on the calculator is the series type oscillator, so it is the wrong calculation, but I just shrugged and tried it anyway, and I am very pleased that it works.

See, the 0.6mA could light the led for 15 seconds, but then it would go out for 12 seconds. Over several hours this slow flash did not improve, so I tried this oscillation enhancing cap.
In fact the 68pF seemed to work but after 15 minutes the light would go out, then go back on, so it could almost keep up.
and
The 220pF put the light out.

Getting back to Mg /C . I will make another one. My 4 carbon rods that were in the earth broke when I took them out, so now I have 8, 5 inch pieces. I will try again later.

I just looked at the circuit again, and I realize that it might be the same, if I turn my head!!

Better rotor for the Stubblefield coil

@All
Lasersaber has posted another video and in it he is showing a different rotor. I used his idea to make a better rotor for my Stubblefield coil. It is suspended from a steel needle by using a small neo magnet attached to the top of the rotor. I was able to do this because my rotor is very light.

barber pole working

Hi everybody,

Well, I managed to get the barber pole battery working.
It was working before, but I wanted to light a white led, and not just a red one.

It turns out, I needed a jtc with a smaller toroid, I think, because all I needed to do was switch jtc and wait for the memory cap to fill and...

it went on and is still on after 2 hours lighting both a red and a white led.!!

another barberpole working

a video showing a barber pole on copper working

Hi all,
This is short.
I made the barber pole today using a copper pipe instead of carbon, and about 60 inches of magnesium as lidmotor showed in yesterday's video.

Copper should not work as well as carbon, but it is much less expensive and easier to get than a piece of carbon that has the same diameter.
So, I used a 3/4 inch pipe which I sanded and wrapped in cotton cloth then wrapped that in densely wound magnesium ribbon, about 60 inches, and it works very well.
I also put a drop of oil onto the magnesium where it is exposed to the air, as lidmotor suggests.
This is very convenient and also portable battery.
I expect it to work very well in the earth too.
The price is right too. I just paid $7 for a 75 foot fool which can make 15 of these.

COOL!!
I am working on an "anti-barber pole" version that has the mg coiled up inside the copper tube. What that does is trap the moisture inside the tube so the battery doesn't dry out as fast. Taking the battery apart is easy to replace the magnesiun ribbon coil---just pull out the old coil and slide in a new one.

plates

jeanna my plates ar detiorating very fast now... i have to put just a little bit of water to the cactus because he was drying... it becames loosing power over the time... it will not be long till i loose my plates completely!

i think i will try with the barber to!

earth battery rod placement

I lost the link to the website that calculates how deep into the ground I place my North copper rod and my South Zinc rod so they will align with earth's magnetic waves (or something like that).

I remember that one rod is deeper into the ground then the other and it's based on where I am on earth.

Anyone have the website link?

Thanks

[jeanna]

@donL
I think Pirate88179 has that. Maybe you can ask him directly. I had it on a different computer, so, sorry, I don't know.

@juju,
Have you marked the time it has taken to deteriorate?
If we can know this we can make batteries with predictable lifespans.

In the weight tests I did, it seems that 1.6gr is needed to light a joule thief for 7-8 days constantly on, but there is much more to learn here. It may be possible to have it last longer than that, because the ribbon usually fails in a few spots but remains fine otherwise. Yours with the fatter piece of metal should last a long time.
My "phyllis battery", which is from a magnesium stone to a copper pipe has run constantly for close to 2 months with a steady-on led, and before it got steady the light flashed for around 3 weeks. This is a total of 2 months and 2 weeks with no sign of failure.

@all,
I just made a jtc custom for use with the "copper pipe/ mg ribbon-almost-air-battery"...
(what's in a name? )

Someone asked me if I could make a jtc that would light up 40 reds and 10 blues for a plant experiment.
I said, "yeah, that would be nice." But the challenge had been set, so, I looked closely at the one jtc that has been best with all these plant and barber poles, and that had two secondaries of 42 turns each, totaling 84T secondary winds on a tor-23 which oscillates really fast and a 2N2222 and 470ohm base resistor so... I did the same thing but with a single 80T secondary.

Well, so far, it's secondary lights 2 whites IN SERIES but not fully bright. And I can see them flicker so the "leads capacitor" should probably be smaller value.
Or, maybe it should be a 1F memory cap like the ones on the other plant batteries...

OK, so there, I am throwing the challenge back out.


I started 2 jtc's today and the next one will have no resistor and a cap like or somewhat like lidmotor's mosquito. I saved that because I think it is the way to go. I will let you know when it is finished...(I am taking a little break.)

hi jeanna...

i dont have measured the weight, but i dont think my 2 plates together had 1gr ... maybe close to that!

i posted it here at 16 of the last month... and i start running it some days after, so maybe is close to 1 month!!

my cactus was outside in the courtyard(covered), i've only been adding very little few water time to time because it will dry with the sun light, and will decrease the led performance, the earth was everytime almost dry and that increased the life time!

i dont know how to know what materials compose my plates of the picture that i showed you, maybe i will ask my friend that is studyng chemestry and he can make some tests on the school lab.!

good luck with your projects

I think that you are showing a very good choice of plant and soil to use.

Here is why I say that.
the roots of the plant move the water past the electrodes, which turns the battery on.
(At least THAT is my explanation for the enhanced activity of the plant battery.)

In a cactus the roots will aggressively pull all the water it can into the plant leaving the soil dry.
So, this means you can regulate the light by briefly watering the soil. The light will go out after a few hours and the electrodes will stop deteriorating.
By using a plant that prefers a dry soil you can have light when you want it.


What I was unable to do was to stop the battery from running.
Even when the ends were disconnected, the magnesium continued to degrade.
That is just because the soil was wet.
So, the only way to stop the battery was to let it get dry.
But this took over a day.

In my study, the plant battery "used up" 1.6gr of magnesium in 8 days always on, which is 192 hours.
If I were to be able to use the plant battery for only 6 hours in the winter evening this should last 32 days.

This is great information, juju.

thank you,

jeanna

@all

I see that the longevity of the battery seem to vary too much , maybe it would be time to get some PH reading and determine if acid or alkaline soil/water is better .

Also i see some great battery ( barber pole / lasersaber ) but those are nothing really special , nice to know hoe to make one , but is a distraction .

Why am i saying that , because the battery needs to be magnetic , i think a bismuth core would be incredible .

But remember magnetic change induce emf in copper , the copper is the battery , the battery part give you dc , the magnetic part induces bemf kicks that will charge a cap beyond the battery potential , since the battery and coil is a combo , the possibility are quite different from a regular battery .

The sooner everyone works on a coil battery the sooner we will have success .

Have a look into Nickel/iron galvanic pair , they last 50 years .

Nickel plated copper will work since the anode is usually not eaten .

I Know for sure that Tesla used it and many others i get the feeling SM did it too .

Lasersaber showed cell working to over 1.5 amps , the surface area is not that great one could build pancake coil from flat wire giving more surface area , one step further using sheets of metal , 1 to 2 inch wide to make a big coil and wind on it fat secondaries , this would make a very strong battery amp wise , the voltage will be risen by the kick .

Yes usually a transformer raises the voltage at the detriment of the current , but this is not a transformer , Unless we test it we will not know ... Some diodes and cap will be useful .Btw maybe NO DIODES since the coil it self could act like one .

Did anyone make scope shoots of the NS ? I must have mist that .


Keep the good work everyone !

hi

how r you guys doing with the SF?

i made a video of my plant battery, testing to kinds of plants, soils... the humidity is almost the same, still have to find one that give me best results that my little cactus!

Hello All
Read to this point in the thread and


Lidmotor[/QUOTE]
The plant is thriving and there is enough metal in there to last a long long time. The cu and mg might need to be periodically pulled out and scrapped. Keeping the soil moist and at the right ph will be the trick. Someone good at growing things would love this project.
QUOTE
I have tried several different Joule Thief circuits and SEC exciter circuits but the JT circuit that is in 'Dewey' is winning the contest. His circuit is a JT charging circuit that has two batteries and a DPDT switch. Paul (Kubikop) came up with the circuit over a year ago and led to me building 'Dewey'. 'Phyllis' simply replaces one of the batteries.
QUOTE
As you found out, a JT circuit can charge another battery while it runs.

Was wondering if the charging circuit might be in some way used to recharge another plant bed?
Kinda like might it assist the microbe's? Or the Plants.
Could it be looped for additional energy. (I'm not a plant person - Like em but they expire for some reason haha)
Just a thought
