Interesting Info on Earth Batteries

Howdy All

Below is posted the thread of a series of posts on earth batteries from a preparedness yahoo group I'm subscribed to. This is my first exposure to earth batteries. I've posted the info below without any organizing effort or editing effort other than to delete some of the continued repetition of old posts in responses.

If anyone has further info or experience with making earth batteries, please post here. Thanks a bunch.

Happy Preparedness Trails,

Jim

Yes I have tried making one.

Best results so far have been with a steel pipe, and a old discarded burkey water carbon filter, got 1.5 V with that. Not much amperage, not a whole lot of power, but still learning. It gets tricky as you try to go in series to build these.

The best info I have found is google books, the old telegraph services ran about exclusively on earth batteries, before that clocks ran on earth batteries.

In the United States there was a guy who made a telephone system with this “Nathan Stubblefield�

Stubblefield, U.S. Patent 600457, "Electric battery", 1898.

So far the power has not been spectacular of those who have done this, but it is a fun hobby. You can light leds with them and small amount of florescent tubes:

For being real practical you will be father ahead getting solar cells and a battery for the amount of time you spend getting this much energy. But.. on the other hand, it is free and runs 24 hours so might make a nice nite light :-)

I am also part of a forum that talks about this stuff…

I have to say I'm intrigued by the plans for the earth battery. Has anyone made one? I noticed it in the photos section. Curious. I'm definitely trying this when the ground thaws!

Yeah, I've got to agree with Matt. This all sounds really interesting but I
suspect the after copper prices, installation efforts, maintenance, you'd
probably be ahead investing in a PV system. But it does sound interesting
enough to go outside and play around with.

Just curious, what other metals did you try as electrodes?

It makes sense the carbon filter would work. That is what is inside a regular D battery.

I wonder how big pieces of screen would work? Or if surface area of the electrode even makes a difference.

Copper, zinc plated metal ( works well ) like he back panels you take off the computer case or even the computer case itself is zinc plated.

Here is a great article about earth batteries. It also lists the voltages of various metals, I now see why the zinc plated one worked so well.
