Earth Electrical Energy Datalogging Experiments

[kamax]

in reference to the above video,
i scratched the oxidized layer off of a soda can, and placed my meter between the can and a piece of copper wire sitting on my desk.

reading:  0.5v

copper/alum battery,  i think this was invented by alejandro volta some 209yrs ago??

The guy on the video use earth to make his cells, volta use salt water. Sorry if my post don't help, i just want to help and try to build soon something between your earth battery and the cells on the video.

Here is how he build this little cells if someone is interested :  http://www.youtube.com/watch?v=6oxanMmAgf0

Maybe it works with steel too.

Kamax:

I have never seen this before.  Thank you for posting it here.  I have no idea what is going on there with the metal and the concrete.  The meter shows 100 volts (just about) yet he is lighting 2 leds.  I would think those would have fried at that voltage.  I favorited it for further analysis.  I wonder how much power he is getting from this?

I can envision 55 gallon drums sized slices filled with cement stacked in my yard.  Very interesting concept.

Thanks again.

volta originally used differing metals to create a voltage potential.

he later incorporated the use of salt-water to increase the current.

@ bill, i have now seen this done 3 different ways.
with concrete inside the aluminum cups.

with dirt inside the aluminum cups

and again, using the cups with the WAX still inside them.

my conclusion is that the copper and aluminum must be separated.  by what doesnt seem to matter.
ergo - concrete is performing the task of insulation.

Smokey:

Thanks.  Do you have any video links to any of the other versions?  I would love to see these as I said, I have never run across this before.  Do you think the copper and or the other metal is being consumed during this type of reaction?  I had never really thought about cement as an insulator before but then, I learn something new here every day.

@IotaYodi,

@electricme or others.
Liquid tape can be found in most hardware stores or electrical supply house. Common item for electricians. Never used the spray type but it may be faster to apply.

Thankyou for this particular item, I sent these people a email yesterday late, asking for a "sample", I havent heard back from them yet, well, if I don't ask, I will never know will I,lol.
