I've had some people get my cells confused with Concentration cell, which are galvanic cells. In no way is my cells a Concentration cell, a Concentration cell uses the same metal like my cells but a Concentration cell uses two different electrolyte that are connected by a salt bridge. My cells are the same metals in the same electrolyte, and the electrolyte is distilled water. The textbooks say my cells should not work but they do. On top of that my cells don't need to be exposed to air or oxygen to work. I find that i get the best life out of my cells when I have the air tight so that no air can come in and so that no water can evaporate out.

As to what determines the positive and negative is still up in the air, I use to think that it was plate size but thats not true anymore. Sometimes the smaller plate is positive and sometimes it negative. It feels like the water determines the positive and negative plates.

A new idea came to my head about my same metal water batteries. Since there is water in the air and that water is as pure as distilled water I think there might be a way for me to treat the water in the air like the water in my cups. Sticking two plates in the air and the water thats between could make my same metal water battery. This could be what Tesla was talking about with his electricity from the air, he could have been tapping the water electricity due to the thunder and lighting.

The water in the air could be the reason why we get radio transmissions?

But this all just an idea as of now.

I've have a old video of one of my attempts at making the same metal water battery into a real battery by putting many cells together. You'll notice I call the same metal water battery a water captret, it was because at the time i was dealing with the captret idea and it seem to act like the captret. I've come to know now that the captret and the this same metal water battery are not really the same, but they do share a lot of similarities. In this video below I show that the battery outputs more power over time when given a load. This is something that normal batteries or even normal water batteries can't do, thus showing that my cells are doing something special.

Testing

I've been doing some testing to see which type of same metal water battery will work best. When I first started working on this I made cells that had one thick folded plate and now I've come to conclusion that folding the plates is not good. The folded plates seem to be affected by the capillary action, where water will rise up and these folded plates are not only trapping water but some type of gas. The capillary action causes the folded plate to expand too which also lowers the output voltage.

To solve this problem is very simple, instead of folding one of the same metal plates I leave both of them not folded but one plate is still bigger than the other. Both plates being not folded still produce the same amount of power show that the charge I was getting had to deal with the surface of the metal.

Another problem I had was with nature itself, causing my water to evaporate. This was very easy to solve all I did was put a plastic wrap on the top of the cell. To solve both problems I myself needing to get a cup with a lid on it and poke holes on the top of it for aluminum plates to go through and seal up the holes so that its air tight. When the cup is air tight with the plates in them I need to feel up the cup up with water till it over flows and then put the lid on it insuring that there's no air inside of the cup. This should make for the best cells. Also only using distilled water will also make things a little better, but tap water can be used so long as the cup is sealed so that the tap water can't evaporate.

Showing that you can even be so clever to make a paper and pencil battery.

Showing that you can also use graphite instead of aluminum.

How to make the same metal water battery:

In this video i say use tap water, but thats because this video is a little old and it went by a different name. You can use distilled water and you don't need to fold that one plate many times but this video gives you a good idea on how this all works.
