So far the green ones, are the best to my knowledge , the 1 k resistor is perfect for it, its a bit less that 1 inch, the 45 v is 1.25 inch (aqua green with a blue side and one all black same size same results there at there best at 50ohm resistor).

Btw , my last project is with the big one even if they are not the best , i can put more turns on it!

@MK1,
Yes,
So, if 6 to 12 turns as secondaries can produce 9-12 volts or whatever, and many single wires can be wrapped with 6-12 turns each around the same toroid, When they are added together, or sent off to an external cap or something that can later be added together, then even a rather sluggish toroid can still be very useful.

It may truly be unnecessary to achieve 120v or 240v in one wire.

I think that may be what ist is up to. (I am afraid I still don't follow ist's experiments too well. But, I am following better. )

But, I want to be thinking about how to put secondary ends of wires into one additive form that doesn't wreck the frequency.

@Gadgetmail,
Is that the pic off the net? or are you the guy who devised that?

It is very cool that tiny jt.

@ MK 1:

Just remember, if you are using the American cent it is zinc and not copper.  I forget where zinc is on the galvanic charts compared to aluminum but unless you use an old one, very old, it has only a microscopic coating of copper which will be destroyed very quickly in an electrolyte.

***EDIT***

Found it:

Potential Differences of metals
Galvanic Series Metal Potential

V Cu/CuSO4 electrode

Magnesium (pure) -1.75
Magnesium (alloy) -1.60
Zinc -1.10
Alluminum (alloy) -1.05
Aluminum (pure) -0.8
Steel (clean) -0.50 to -0.80
Steel (rusted) -0.20 to -0.50
Cast Iron -0.50
Lead -0.50
Steel (concrete) -0.20
Copper -0.20
Brass -0.20
Bronze -0.20
Steel (mill scale) -0.20
Cast iron (high silicon) -0.20
Carbon +0.30
Graphite +0.30
Coke +0.30


Now you can see why I use carbon rods and magnesium blocks on my earth batteries.  They offer almost the most potential difference.  And, using the earth as an electrolyte does not appear to eat up the electrodes in any way....at least not so far.  I hope this helps.

for all you hydrogen nuts try this.  take normal household aluminum foil make 2 electrodes from it and submerge them half way into salty water, now allow the electricity to flow! while it produces electricity it also produces hydrogen and unfortunately disolves the aluminum in the process.

fun stuff......

@Pirate

I am a crazy Canadian , like ist. lol

Edit : I know all about the galvanic scale don't worry , I light led with 8 cents and some foil , coke (the cola)with salt electrolyte.

What make earth good is the potassium in it, fertilizer , bananas , potato are also good. (koh)
