Captret - Capacitor and Electret

[gravityblock]

You keep forgetting that i'm not using it as a rectifier. I'm using it as a battery. A battery and rectifier are two very different things.

It doesn't matter.  Without the thin layers of oxide, then it's just a battery.  With the thin layers of oxide, then it's an electrolytic rectifier.  I can't make it any more clearer to you than this.

I'm sorry it does matter. A rectifier or diode blocks electricity from flowing in a certain direction. A battery gives you the electricity. I don't see how you're mistaking a diode for a battery, both are really different. Also this effect is not only limited to aluminum but Brass also does the same-thing too.

If you look at what it says "only aluminium electrodes were used, and used on A.C., there was no polarization and thus no rectifier action". It clearly says that when you use only aluminum electrodes there was no RECTIFIER ACTION, so even they say its not a rectifier when aluminum is only used.

You are confusing the process of using dissimilar metals with non dissimilar metals. When they used Aluminum with another metal electrode like lead they would - "The rectification action is due to a thin coating of aluminum hydroxide on the aluminum electrode, formed by first applying a strong current to the cell to build up the coating". I'm not not applying any current to them. The water captret is giving off voltage, just like a battery would and not blocking it like a diode would.

Like i said i don't understand how you're confusing a battery with a diode.

I'm not confusing a battery with a diode.  An electrolytic capacitor has a thin layer of oxide on the aluminum.  When you connect this electrolytic capacitor in the "captret mode", then the capacitor will act as an electrolytic rectifier when the breakdown voltage of this thin layer of oxide is exceeded (This is exactly how an electrolytic rectifier functions).  The water battery with no oxide layer on the aluminum is just a battery. Add an electrolytic solution, such as borax or baking soda, to this water battery and it can now act as an electrolytic rectifier just like an electrolytic capacitor connected in the "captret mode".

Unlike the rectifier, above, only aluminium electrodes were used, and used on A.C., there was no polarization and thus no rectifier action, but the chemistry was similar.

There may not have been any rectifier action with AC, but you convieniently left out how the chemistry was similar.  The water battery is producing it's voltage from a difference in surface area of the aluminum plates.  Since the water battery is producing DC from this potential difference in surface area, then if there is a thin layer of oxide it will lead to a rectifier action if the breakdown voltage of this thin layer is exceeded.  An electrolytic capacitor connected in the "captret mode" is nothing more than an electroyltic rectifier.

Should be fairly simple to test this theory by using two identical size strips of aluminum

I would like to point something out that was brought to my attention on one of my youtube videos. Since i said that aluminum and brass works Mrb00k5 had pointed out to me that both aluminum and brass are paramagnetic metals and i know for a fact that water is diamagnetic. Could this be the reason why i get voltage from my water captret?

Mrbr00k5 also pointed out that copper is paramagnetic too, and it does work.

I'm glad he pointed that out, all possibilities are welcomed.
