Almost perpetual water batteries.

[MagnaProp]

Hi stevensrd1. It's good work you are doing with your water batteries. Can you estimate how much water it would take to power a hand drill with one of your water batteries? Would this swimming pool be big enough? If not, how many of them do you estimate you would need?

  I remember back in the Bedini days, a guy did a thing called a Tune Charger. Even did a patent. Used a solar cell as input and used to charge batts. It would keep charging  when the input at low readings. Using one of those and a few of your water bats could be a thing.
Just an idea.

I DO NOT KNOW WHAT THE HELL THEY ARE SAYING BUT WHEN THE SHTF EMERGENCY
IT WILL KEEP YOU OUT OF THE DARK.

Yeah it's useful for me.

The volume of water can be negligible.
Only a small layer is needed between the electrodes.
A simple voltaic pile can be made from small disks of magnesium and copper
Separated by a piece of paper soaked in water.
(but will quickly dry out and stop operating if not sealed)


These batteries potentially can carry a higher energy density than lithium-ions
In a slow oxidation reaction, very long lifetimes can be achieved,
at the cost of lower output currents.


Copper is not the only electrode material that can be used, but is readily available.


(Caution: when cleaning copper with vinegar you are forming a toxic metal salt called Copper Acetate.
           This is a blue color.
     It will soak into your skin, replacing natural acetate salts in your body, and in high concentrations can cause organ failure. Be extremely careful not to get this on you. And dispose of it in a responsible manner to prevent environmental contamination. If you do not have access to a suitable disposal facility, you can place the liquid in a clear container and place in sunlight.
Over time, the acetic acid molecule will degrade leaving copper oxide powder at the bottom, and a relatively inert acetic acid solution.)
