Picture of Earth battery.
Earth batteries have been used for centuries, but it more recent times they were used in the 1800's to power telegraph stations. In this instructable we will try to replicate the earth battery in two forms. First as a single cell and then as multiple cells. How successful will we be? Will it be free electricity?


Note: This project is not for use during a electrical or thunderstorm. If there is lightning, wait for some other time. Also before any digging is done, please check with authorities to make sure you will not endanger yourself, others, or the utility conduits. I will not be responsible for any issues. Practice common sense. If you are not sure, get an expert to help.

Warning: I will not be responsible for any issues from this project. It is up to you to get an expert if you feel uncomfortable in this project. Since you are stringing out wire and pushing posts in the ground, it will be up to you to protect against any safety issues for humans and or animals..

Note:.   Our goal is to power router and low power servers. many people have asked me to give test results. Have not done so as to encourage you to try it yourself. I will say that even just putting the stakes in the grond yeiled a voltage.

While that is some very noble thinking, unfortunately water is not the "fuel" for an earth battery. The stubble-field battery instead uses water as an ion transport medium for the chemical reaction taking place between the copper and aluminum plates. As soon as the plates oxidize, you will have no more reaction. These types of batteries are nice though considering that copper and aluminum (or magnesium) have a long dry shelf life compared to most batteries that are liquid-activated upon construction.

Thank you for your explanation. This is not a Stubblefield battery.

Do you have to have aluminum foil strips for wires?

I prigially intended to use alumionium rolled up but I eneded using.steel wire. I still may go back and use the foil.

That's nice. Better if we have some real phots of the project :D.

Verything is buried underground, so not much to see.

Well we finally had some rain. The ground should no longer be rock hard. Need to do some maintenance back there, then I will do some more on the project.

What results did you get - volts/amps?

What are the high value caps for - energy smoothing?
Computothought (author)  sam D3 years ago
Yes about the capacitors. When I put up the pics, I will also include more details. Hopefully by this weekend.
