Guys have a look a this fire from a potato.

One potato emptied in the middle filed with salt and toothpaste , 2 wire they seem the same material , so i don't thing galvanic here , 5 minute and voila enough current to start a fire , its probably a trick but if real really worth looking into .

Potato juice any one !

That's a funny one, Mark.
I could see some little sparks coming out of the wire.

Thank you for the kind words and yes you are correct, I am not using a joule thief.  This A is going for 6 full days and no visible degradation.
@old man
You mentioned the Edison Battery and I looked at your attachment.  Something I found interesting was that he placed his copper below the zinc.  I messed with copper and magnesium ribbon last night and (not scientific) noticed that my LED was brighter when the magnesium was on top of the copper and as close as possible to the copper.  I am attaching v.2 of my “RX Water Battery” for your review.  So far it looks promising, though time will tell.

I am even worse than a newbie in that my knowledge of energy would not fill a thimble.  Please feel free to offer advice â€" but please keep it simple or I will probably not understand.
Thanks,

Ok i made some pictures , this is a aluminum /copper cell , it has been active for over one week , copper is only plated on each side of really slim PC board
and the aluminum you will see in the picture .

I was checking the voltage and amps it has over 22 mili , so i decided to take a picture i started playing with is it went down  , this design is really temperamental , i will keep at it ...

Size 470 millimeters by 40 .
