How to make a powerful water battery

 by JimJong
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.

-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

Really neat

it is environmentally everything is environmentally because it all came from there earth at some point and its just going back to the earth so if you think about it there is nothing us humans can do that unnatural because of the fact that you can't make something from nothing

God dam how do i make it i dont understand but tahnks for telling

Is there any replacement for rain water ?

im going to try to make one smaller.

Still want to know the power output?
lukeD says: Mar 27, 2011. 8:18 AM
how many volts/amperes come out?
lemonie says: Apr 18, 2009. 12:34 PM
because it can run solely on rain water.
No, it needs the zinc. Which has to be mined as ore and requires a lot of environmentally-unfriendly energy to refine into metal (if the mining weren't enough for ya...)

If it can't be grown it must be mined!!!!!!!!!
lemonie in reply to swilusDec 10, 2010. 1:49 PM

Yes (old comment to reply to, did you look at my stuff?)

Actually, if the electrolyte soltution is drained into a container, the dissolved zinc particles can be plated onto another metal so ha.
lemonie in reply to JimJongJul 11, 2009. 2:21 AM
How would you plate the zinc onto another metal? (Or recycle it) L
JimJong (author) in reply to lemonieJul 11, 2009. 3:51 PM
I think you put a more reactive (or less) metal into the water and it geets replaced by it or something. Heres something you can do to prove it. Pour some vinegar in a bowl and add a few tbsp of salt. Then drop 6 or 7 pennies in it. wait 30 min then take them out. now drop an ungalvanised iron nail in the solution. wait 30 min and there should be a coat of copper on it. not much but enough to see that it works.
scratchr in reply to JimJongJun 25, 2010. 7:45 PM
These batteries work by oxidation. the zinc wants to give ions to the copper. You can only reverse it with electricity.
lemonie in reply to JimJongJul 11, 2009. 10:53 PM
More reactive, see the table here. But you still need fresh metal to do this, so the same energy / environmental issues apply.

JimJong (author) in reply to lemonieJul 11, 2009. 11:31 PM
but if the plated metal is removed from the more reactive one you can use the more reactive one over and over agen
lemonie in reply to JimJongJul 12, 2009. 1:21 AM
The energy comes from oxidation of metal, whichever way you do it you still need more metal (of some kind).This is why people developed rechargeable cells. L
JimJong (author) in reply to lemonieJul 12, 2009. 2:39 AM
why would you need more metal? you start with a rod of metal more reactive than zinc. the battery and a seperate container. when the zinc all oxidises it is re harvested onto the rod and re inserted. its that simple. oh and rechargable cells need ENERGY to charge. and let me ask you this, Where did that energy come from? most likely fossil fuels. I think ive made my point.
DrCoolSanta in reply to JimJongNov 13, 2009. 5:14 AM
The electrolyte that you collect contains Zinc in the dissolved form (more like an ionic compound).
When you put the more reactive metal in it, it replaces the Zinc in the electrolyte, so the electrolyte now contains the metal in the dissolved form and a layer of Zinc is formed.
So, the metal is actually getting consumed to give you back the Zinc.

In your earlier example, when you put the pennies in the vinegar, it forms copper acetate.
2CH3COOH + Cu -> Cu(CH3COO)2 + H2
Next when you put the iron in, since it is more reactive
Cu(CH3COO)2 + Fe -> Fe(CH3COO)2 + Cu
You see, the copper being formed here leads to that layer of copper, but the iron itself has now become Fe(CH3COO)2 which is basically not Iron.
To get back this Iron, you need to provide energy, and in doing so you will have to provide more energy than you actually produced.

You still don't understand electrochemistry - so I give up trying to explain it to you. (Rechargeables can be recharged from many different sources) L

He said it can run on rainwater, that in itself is environmentally friendly. The parts to build it are not though.
lemonie in reply to nicholastJul 7, 2009. 11:02 AM
It runs with rainwater, the source of energy is chemical oxidation of the metal. As you observe, apart from the rainwater nothing in this is really environment-friendly.

L
nicholast in reply to lemonieJul 7, 2009. 11:33 AM
Your right. But really nothing else we use everyday is environment-friendly either. And a good point is that its not using a fossil fuel of some kind, so less pollution. Although I don't know what damage the metals in it cause when scrapped, that could be pretty bad depending on how well its recycled.
lemonie in reply to nicholastJul 7, 2009. 12:15 PM
The fossil fuels are used to extract & refine the metal and produce the PVC. A generator powered by naturally flowing water would be better. Old tech, but water works (like that) L
nicholast in reply to lemonieJul 7, 2009. 12:38 PM
The one time use of fuel to make the materials is better than the continuous use in say, a generator.
lemonie in reply to nicholastJul 7, 2009. 1:55 PM
A water powered generator may use the materials for years. Chemical oxidation to electricity will consume the metal in a matter of hours continual use.
I'm not sure what you're saying here?

JimJong (author) in reply to lemonieJul 10, 2009. 7:32 PM
But you can not destroy an element, as some guy once said, so it is still there. Meaning that if you harvest it it can be reused.
lemonie in reply to JimJongJul 11, 2009. 2:22 AM
How? L
JimJong (author) in reply to lemonieJul 11, 2009. 3:54 PM
look up
nicholast in reply to lemonieJul 7, 2009. 2:26 PM
Oh, sorry I meant a gas or diesel generator
lemonie in reply to nicholastJul 7, 2009. 2:45 PM
Oh aye. L
Gilo in reply to lemonieApr 18, 2009. 5:43 PM
i am beginning to wonder why you call yourself 'lemonie.' btw, lemons also could be made to put out electricity. also, those prius cars had a lot of stuff mined from somewhere. check out the pc you are using right now; lots of mined stuff there too. if you are using a laptop, i need not say more about the batteries in it. convince me Lemonie that you are without sin. anybody out there without sin who can throw the first battery at this fun build?
lemonie in reply to GiloApr 19, 2009. 5:40 AM
The comment was on the false claim "This battery is environmentally friendly because it can run solely on rain water" - I'm not bothered about the rest of it. L
Gilo in reply to lemonieApr 19, 2009. 11:07 AM
Lemonie, The instructable didn't have to make that claim.If you know just about two cents worth of the chemistry of producing electricity, it goes without saying that there will be other components in the mix besides plain rain water. So I just hope you 'll have fun and enjoy the idea shared to people like us.
ewookie in reply to GiloOct 5, 2012. 8:08 AM
wow. everyone seems to agree that lemonie is right except for the 12 year old kid he was trying to educate. yet, everyone admonishes lemonie for trying to educate the 12 year old kid...instead of admonishing the 12 year old kid for arguing with someone that obviously knows more about the subject.

this is how the world gets dumber everyday.
lemonie in reply to GiloApr 19, 2009. 11:29 AM
Hi Gilo

It's not environmentally friendly, it can't run solely on rain water. Perhaps you see the statement a fun joke? That being the case our senses of humour must differ, and there's not much fun for either of us to bicker about it.

L
Gilo in reply to lemonieApr 19, 2009. 4:00 PM
You have taken the 'fun' word out of context. Let me rephrase it: take the instructional as it is presented and dont lecture everybody about the evils of mining stuff out of the earth. Everybody knows that. Taking you on your point, let me ask you: Are using using anything now that wasn't mined? If you can say yes, I bow to you. and my lips shall be shut forever on this issue. It is a nice today. I hope you are enjoying it.
lemonie in reply to GiloApr 19, 2009. 11:39 PM
Yes today is nice, I probably shall enjoy it as I drive to work in my recycled cardboard sports car that runs solely on dewdrops and sunshine... L
