Homemade Battery! - The DIY 'Earth Battery' - Powers Clocks/Watches/Calcs/LED Lights....

Homemade Battery. The DIY "Earth Battery". Earth Batteries are easy to make and produce enough power to run many items such as Lcd clocks, watches, pedometers, calculators, LED lighting and more. all that's needed is copper wire (from old extension cord etc.), several small bolts (screws or nails can also be used), an ice cube tray and dirt. that's it. makes a quick and easy battery. works best if it's made with moist dirt/soil. Note: every couple of days the dirt will "dry out" and the voltage will decrease. TO RECHARGE THE BATTERY; just add 1 or 2 teaspoons of water to each "cell" and the battery will be "recharged". for increased voltage make more than one battery and hook them together. Tip: try to use "galvanized" bolts, screws or nails - as they work the best. *included in this video is footage of a larger outdoor "single cell" earth battery i made. it's made using a 2' long piece of copper pipe and a giant (foot long) nail.

omfg! first time I did this in my life. got 12.66 volts!! it works!! I used the gold looking zinc plated bolts and squeezed half a lime in cup of water.

[xaviersalinas]

this actually works, made myself one yesterday for my electricity class

If you push the bolts deeper in the dirt (if possible) then you get a bit more voltage. In your case you couldn't do it. A bit more deeper cells and longer bolts could have made it. This advice was only for the bolts and not the copper. No need to get the copper deeper. However, a few more cells do the same thing if needed, to get more volts. A combination of Stainless steel and aluminum works also well and I prefer that, especially if you want to dip often.

Very nice video, by the way. Thanks!

thanks for helping me get first place for engineering in the science fair 4 years ago. i even got accepted into nationals but i was stopped there. not like i wanted to go any further, i just wanted the pizza party

Electricity is induced when two dissimilar alloys are in the presence of an electrolyte. You would improve upon this model by having a copper rod, your zinc coated bolts (galvanized) in each of the cells (cubes) then connecting them in series until the desired voltage is reached (may have to increase the number of cells under a load) then connect the same about in parallel to increase the amp hour rating of each earth battery so that is can power useful things (chargers ect.) You might also introduce a bit of salt water (an electrolyte) to improve conductivity and the electrolysis process.

I actually tested my own after watching this to confirm its not a scam, but it's real!!

instructions unclear i ended up making an arc reactor...from plastic bags.

Love the information. I enjoy your videos. If an apocalypse happens, people are going to regret not watching these. Thanks for all the work.

My question is how long can it light a light bulb

[blackadder]

This is Science for everyone! Great video for simply gadgets!

[macgeek]

Adds a whole new meaning to the phrase, "connect your circuit to _ground_!" ;~P LOL

[andrew_owens]

If I understand, the dirt is neutral. Isn't the reaction between the copper and the nail?

[detroitgoth]

I just made this using zinc plated iron bolts and got 6.8 volts out of it.

Magnesium Joint Sachet
The magnesium filings were saved. I placed them in a piece of paper towel. I laid a bare stranded copper wire in the filings. Then rolled the group like a joint. I then bent the metal joint in half and sealed it shut with a second piece of copper. I completed the magnesium sachet by twisting both wires together. I then tested the magnesium sachet with carbon in a tap water bath. The amps came in at 1.3 milliamperes. Again, the shaving have points and powered metal has alot of surface area by mass. This was a very small amount. This is the technique of modern battery manufacturing. It works well.

A tip from a curious Brazilian:
Try to use salt just below each earth cell, it will probably help when they are refilled with water.

Gotta keep some copper wires and galvanized bolts in my car in case of an emergency hahaha

[SlyPearTree]

What's the internal resistance of something like this? Open circuit voltage is one thing, but how much does it drop when there's a load?

The Great Pyramid of Giza was actually a power producing machine ...
There are large aquifer's under these pyramids which add to the earths generation of power ....I think it you applied this technology to an area where there is a large under ground aquifers you would produce more power ..

I am from India and I have achieved 1st prize in my science project competition . Thankyou for sharing your knowledge and helping me . I love your behaviour and explanation .
Thankyou so much

If I understand the theory right, (I’ve been learning Ohms law for two weeks now so forgive if I’m wrong), copper and galvanized metals (as well as others) have two different levels of conductivity. They are both conductors, but one is more efficient than the other creating an imbalance. Electrons want to travel from one pole to the other (toward the path of least resistance, or the neutral pole) which creates electromotive force, AKA "voltage".
A battery does not "create" electricity, but "stores" it, which in my mind makes this more of a natural “generator” than a battery, unless the earth itself is viewed as the storage battery, and using the two different metals channels the flow of voltage.
The earth itself provides the electric charge, (through gravity/magnetism I think) so connecting several of these power “generator/batteries” systems together in series should double the voltage in each group. Hooking them in series parallel should also up the amps. If you used deep cycle truck batteries as storage and these earth generators/batteries as a charging source, you would have a reserve capacity in your battery bank similar to those in a solar power system. Any thoughts?
