Introduction: How to Make a Powerful Water Battery

About: Hello!

In this Instructable I will explain how to make a powerful battery that runs on rain water!

This battery is environmentally friendly because it can run on rain water.It still needs the metals. Distilled water will NOT work, it has to be conductive. Whenever it runs out of power you just have to drain the water and refill it. If more power is needed, you can add a little bit of Clorox Bleach. It also works with other electrolytes, like lemon juice, vinegar, saltwater, or baking soda.

This is my first instructable so i am welcome to any criticism or suggestions.

Disclaimer: Alot of the methods of cutting, drilling, hammering, pummeling, incinerating, and sawing that I describe are dangerous and I strongly suggest you should go about all of the cutting, drilling, hammering, pummeling, incinerating, and sawing in your own manner that is safer than mine. I take no responsibilty for the actions you take concerning this instructable. Have fun! =).

By the way, this battery will only produce about 1 volt but will get a lot of current. For more voltage, hook together alot in a circuit.

PS: Just so you know, I'm only 12.

PPS: For you instructables admins, my dad made the account.

Step 1: Materials

To make the battery you will need some stuff (obviously).
-2 feet of 3/4" pvc pipe
-2 feet of 1/2" copper pipe
-2 feet of 7/16" zinc plated threaded rod
-2 3/4" pvc endcaps
-1 3/4" pvc coupler
-1 3/4" pvc threaded endcap
-1 what looks like a 3/4" tee with a 1/2" threaded middle thingie
-1 1/2" copper endcap
-dremel
-sharpie
-measuring tape
-hacksaw
-electrical tape
-pvc glue
-pliers
-multimeter (optional)

Step 2: Getting Your Materials Ready...

OK, so first off you're going to have to cut your 2' pvc pipe in half. You also need to cut 3 1/2" off of one of the halves. This is so you can attach the tee. Next, you need to wrap the very edge of your zinc rod in enough electrical tape to fit snugly in the copper pipe. Also wrap it 1 1/2" away from the other edge with the same amount. Wrap the middle too. Now for the copper pipe, starting 3" away from the edge you have to cut a lot of holes for water to be able to get in. I did them evenly spaced but you can do it whatever way you want to. For the last part you need to take one of your endcaps and drill a copper pipe sized hole in it. You also take your other endcap and drill a zinc rod sized hole in it. Also solder the 1/2" endcap onto the copper pipe end without holes.

Step 3: Assembling It...

Okay, so now you have to slip the zinc rod through the corresponding endcap. Once you have that done then slip the copper pipe through the corresponding endcap. Finally, pvc glue the zinc rod endcap onto the pvc pipe, side doesn't matter. Also glue the copper pipe endcap to the other side. MAKE SURE YOU SLIDE THE COPPER PIPE OVER THE ZINC ROD AS YOU DO IT.

Step 4: Finish....

So now that you are done you have to water proof it for it not to leak. Just apply silicone sealant to the zinc rod joint and copper pipe joint. Wait for it to dry and you are done!

    Well i am so glad that you made me aware of this it will allow me to reduce my energy bill by many of hundreds of dollars . and just because you are 12 doesn't mean you cant contribute to our world im a high school graduate with a phd and you have just thought me how to take a piece of pipe and make a battery that will produce enough energy to light up my work shop and some of my home if not all of it . thank you sir !

    JimJong -
    I am a retired Electrical Engineer (BSEE). I'm 65 years old.

    Good job on making a "wet cell" out of two dissimilar metals! Have you experimented with this battery much? Do you know how many charge-discharge cycles you can get out of it before it is seriously degraded?

    Do you know how a lead-acid car battery works? It doesn't use two different metals. It uses lead and lead-sulfate for the two electrodes in a very strong hydrogen sulfate acid. You can check it out on Wikipedia here:
    https://en.wikipedia.org/wiki/Lead%E2%80%93acid_ba...

    The reason we don't use Lead Acid batteries in new electric cars is that they are way too heavy, AND they take 14-16 hours to charge fully using a "trickle charger" which charges them slowly to reverse the chemical reaction in the battery.

    BTW, if you think about it, you will realize that a New electric car uses the car's battery in a very different way than the old Internal Combustion Engine cars (ICE cars) do. The electric vehicles store ALL the car's power in the Lithium-Ion batteries... where as the lead-acid battery is really used only for getting the ICE car started, and for keeping a stored power for the spark plugs in an ICE car. Where does the ICE car get all it's power? The energy is stored in the gasoline, not in the car's battery! The battery is only used to help burn the gasoline by firing the spark plugs.

    Hope you like what I wrote!

    If you like batteries, check out "Flow Batteries". This is a new type of battery which can be scaled up to almost any size, but is not suitable for mobile applications like cars. But it is being used for power storage from Solar and Wind systems.

    Cheers JimJong!

    Can you charge this battery to get a higher voltage, or do you have to keep replacing water.

    Yes, you can charge the battery, but you can't increase it more than 4 volts per cell. if you want to add voltage just add more, smaller cells.

    This is similar to a salt water battery and the voltage depends on salinity or acidity the water is. the more acidic or concentrated, the higher the voltage. this could be from 1.23 volts to roughly 4 volts.

    can it be recharged ? as in via solar panel ?

    Yes. normal saltwater or baking soda batteries are rechargeable. the other good thing is that it can discharge energy quick and is extremely safe. it won't blow up or thermally discharge like a lithium battery.

    if not then it may be more discribed as a generater

    I think since it consumes the electrolyte, you could technically refer to it as a generator. You recharge it by replacing the electrolyte.

    Just wondering, you say this has a high current potential, any idea on the actual current output?

    Yes. It really just depends on how much salt or baking soda is in water (the electrode) or how acidic the lemon juice or vinegar is. The acidity or concentration will control voltage. the energy density per pound of material in the electrode battery is about 460 watts/ hour. It could be 1.23 to 4 volts depending. just divide the voltage by energy density. So the answer is yes because if you have a low concentration of electrode (But enough to conduct.) it will a high ampere potential.

    I like it but how does it work

    It works by using 2 materials that either have an excess of electrons or
    not enough. In this example the copper has to many electrons and the
    zinc to little. electrolytes such as baking soda with water and salt
    water work to move the electricity. the reason why it needs water is
    because salt and baking soda won't chemically react without water. Acids
    like lemon juice and vinegar work because the erode at the material
    with more electrons and carries it to the material with less electrons
    than needed. when the electrons flow between these two areas when a load
    (such as a light) occurs it generates electricity.

    It simply works due to the chemical reaction of putting to metals together in water. Using Clorox or coke instead of water works as well but will eat away at the metals faster.

    because of travelling ions from water, u can also use urine in some harsh conditions.
