Water battery

[nightlife]

jeanna, the wire was only 8 and I only stripped about 1inch of the insulation off from both ends. The metal I used was strapping that holds up duct work. It was about 1.5 inches wide and 5 inches long. I then used a piece of metal that was about 3 inches wide and 5 inches long and the voltage doubled. The wider the metal used, the more voltage I got. They were all galvanized as far as I could tell by looking at them.

I hope that helps.

hansvonlieven, I found the following about galvantic action.

"Alternatively if you can not afford the cost of a galvanic isolator unplugging your shoreline when the boat is not in use breaks the metallic bond preventing any galvanic action taking place."

That tells me that iron in a cup of water would not have a galvanic action as long as the iron is not attached to anything. What are your thoughts on this?

Nightlife,
Yesterday I found a big sheet of coppr in the thrift store. It was in the form of a copper aspic mold. I put a little water in it and some sodium carbonate (washing soda from arm n hammer). Then I placed a piece of unprinted newsprint on the copper surface and on top of that a piece of steel/iron from last month's welding class. It gave a pretty good galvanic reaction. In fact better than any I have seen inside the house. Notice the Plus probe is on the copper.
please go the earth battery page where I made a joke of it. ( because local joe had made the turkey choke joke)
I think it might say a bit about surface area or something, I dunno.

jeanna, sorry it took so long for me to get back to you. I did see your comment on the other thread with your picture and it gave me a couple idea's, so thank you for that.

Do you know how long a galvanic action will last? Or if it looses power over time? I am also wondering if they can be put in parallel as well as in series if they would create more amperage?

Below is a sketch of a single cell idea that could be put in series as well as in parallel.

I wonder what would happen if you used palladium?
