Some Rolled Earth Battery Capacitor Questions

[YoderIII]

Thanks for your answers! So I have a some follow up questions.

So when the separator is thicker capacitance goes down? What about when high voltages are involved? Bleed over? Because when this is put into the ground outside it should be taping the Aether.

If the separator determines the capacitance should I try to wind it tighter? Use a thinner separator?

Should more surface area increase the voltage? Have I gone about this wrong? I know if you use plates (copper and aluminum) (Iron and aluminum) with a separator put into the ground outside you just use more surface area. Meaning adding more plates or using larger plates to increase the voltage. I used 200 sq feet of metal. Should I not get more voltage? Do I need a bigger pipe for my center? 1 inch 2 inches?

Loading the earth battery with a resistor would increase the voltage?

Lastly, I do plan to build a Joule thief. I first need to determine that this earth battery capacitor is working correctly. 

Again thanks for your help.

it sounds like you've mostly made a battery - one electrode is a roll of metal sheet, the other is just a rod - not much area in common for a capacitor - but construction is similar to some battery technologies

BTW, just for reference i think you'll find that capacitance decreases with thickness of separator


almost twice as much as Bill Mehess 

(614mV)

but your current is probably 100s of times larger!

126mA (the difference in short-circuit meter current readings due to different internal shunt resistance for the different current ranges)

...so you'll probably be able to run quite a powerful Joule Thief from your 'Earth Battery'

hope this helps

[EDIT - oops - crossed post with Gyula - forget i spoke!  ]

If I understand then  I need a different meter to measure the current? If so what would you recommend?

Thanks for your help.

Yes. Study this link to get it:

What about when high voltages are involved? Bleed over? Because when this is put into the ground outside it should be taping the Aether.

It depends on the insulator properties (you happen to use) at what HV it breaks down. By the way when you put it into the ground there can be no HV involved at all.

If the separator determines the capacitance should I try to wind it tighter? Use a thinner separator?

Yes.

Should more surface area increase the voltage?

More surface area mainly increases current, voltage is mainly determined by the galvanic voltage distance of the two different metals.

I know if you use plates (copper and aluminum) (Iron and aluminum) with a separator put into the ground outside you just use more surface area. Meaning adding more plates or using larger plates to increase the voltage. I used 200 sq feet of metal. Should I not get more voltage? Do I need a bigger pipe for my center? 1 inch 2 inches?

You have to study another thread in this forum: http://www.overunity.com/index.php?topic=3500.0

Loading the earth battery with a resistor would increase the voltage?

No.  The voltage depends on how heavy or easy a load is (any load). Please study this:

OK, I need to make a circuit with a Lamp as example and a resistor as suggested, then measure the current. This will tell me a possible current of 100's of times larger?

Very Interesting!  I am also building an earth capacitor.  Im using a 3 foot aluminum pipe, plastic scrren mesh for the insulator, and insulated copper wire.  I tried sanding away the top layer of insulation off of the copper wire, but I found that the wire would snap if it was accidentally sanded too much/hard.  In that case, would it be ok to solder the broken wires together to maintain the connection? After reading this, Im gonna try to finish up the first layer by tomorrow.  I halted to the project temporarily to finish building the fuelless heater.
