Earth Energy Batteries

Okay, sounds fair.  There is only one other variable.  Soil quality.  I don't have the resources to conduct periodic soil quality and moisture content tests throughout the experiment.  If we are willing to forego that, I will start gathering materials.

Hi Kysmett,

I don't think repeated soil quality or moisture tests are too important. What should be done though, is
find a location where you don't think soil moisture will change much during the experiment. Once the
battery is buried it might be a good idea to cover the area with a plastic sheet to help prevent any
moisture change. Saving a dried sample of the soil from the area would be a good idea too.

Well, I'm sure there are some other things that can be done to make this a good experiment, but
they can be hashed out later.

I have a problem when i connect them in series to get 12 volts

With one battery (copper pipe and zink rod) i have 1.1 volt add one battery in serie i have 1.8 volt and add third i have only 2 volt my maximum with 10 battery is only
2.2 volt

you have them too near to each other.
You have to insolate them from each other, otherwise
the moist ground builds a shortout for the voltage,
although you would get higher currents due to higher
metal surface...

I have put 1 feet between each pipe (battery)

Sorry for my bad english!
