Step 10 You Are Done

You are done. You just need to refill it a again after it run-out of power. Adding more water batteries would be better.

ooo, try gatorade! (lotsa electrolytes in thurr!) :D

[yukthi]

yeah u r correct !!!

[pblanscet]

lol! scientificaly, would this really work?

[ASCAS]

yes

This is a Triboelectric! See this site for more information about Triboelectric series: http://www.siliconfareast.com/tribo_series.htm

What happens to the water? I mean, does it just disintegrate? Or is the salt used up? I dont want to waste the limited amount of water we have on Earth. This really is a big question I have, if anyone could answer this, please, be my guest.

[fjohn]

hey ur not wastin water that water inside is abt 2ml and can last abt 1 month i think so ur not wastin water ur conservin energy...and if u really want u can put waster water

[ASCAS]

Actually the battery only dehydrates the water. It's still water bayt with less minerals. You can still replace those minerals in some ways. Its still renewable.

[skysaber89]

Thank you, i just didn't want to waste water, since, you know, we only have so much water on Earth.

I think you can use sea water for your water battery (Since sea-water has salt, it should even be better than fresh water)

So, no worries :D

[noingwhat]

How much voltage and current do you get out of something like this?
And if you were to make it bigger or smaller, would that affect the voltage or current?

[MCzone]

how power full is this battery
can you use it for a flash light

[Pale_Flyer]

try copper and zinc with an acid, like lemon juice or vinegar...

[Xyver]

Thats actually really cool.... What's the chemistry behind it?

[elephant1292]

I would imagine that this is occurring because of the difference in electronegativity between the electrodes. That is, the aluminum/zinc has less of an attraction for its electrons than the carbon, and so they move through the circuit from the metal to the carbon rod. The ions in the water oxidize and reduce the carbon and metal electrodes, respectively, to maintain balance. Zinc works better because it is less electronegative than the aluminum. Try it with copper or nickel, those would probably work even better.

Hmm... that is an interesting idea, but I think its works the same way that regular batteries do just using salt water for the electrolyte. Since most water contains salts that is why this works with tap water. I don't think this would work with distilled water. Someone should try that? Basically the salts in the water react with the carbon and metal and produce electrons. That is why water

[Tchnclfl]

Distilled water is indeed nonconducting, so it wouldn't work (at least not well enough).

[elephant1292]

"Regular" batteries do work in this way, although I cannot say that all do. They generally contain strictly controlled types of ions, but it doesn't matter that much as long as the basic structure of the system is maintained. I'm sure you know that vinegar contains quite a few more ions than standard tap water, explaining its described success as an electrolyte.

Brawndo has what batteries crave!

[joosh]

:) I love idiocracy. Batteries need water. Like from the toilet?

[bbrown26]

I know you where being stupid but I saw you talked about toilets... So do you think urine would work??? It would give you brownie points for re-using waste...

[Javin007]

Probably one of my favorite movies of all time, mostly because you can actually SEE everything they're talking about in action all around us. The general dumbing down of society, etc. That's why I spend so much time on instructables. I figure SOMEONE'S going to have to know how to do the basics here in a few years.

[joosh]

I totally agree with you. I look around and I see the world going towards that. Well at least America is. I blame it on this narcissistic instant gratification entitlement everyone has. My generation seems to be the worst. Also I blame it on the internet, but some sites (like Instructables help).

[Javin007]

I think they might have had it pegged in the movie. We're just breeding ourselves into stupidity. Just look at YouTube and think to yourself, "The vast majority of those people are breeding profusely." This could even be the CAUSE of the "narcissistic instant gratification entitlement" generation.

[joosh]

Yeah you're right. I just love the interview at the beginning of the movie. Sadly its true. The stupid people have 10x as many kids. I'm not saying stupid people only have stupid kids, but its more likely. Another thing that I just thought of (because my dad was watching Glen Beck) is the media. The media is dumbing us down by just filling us with bullcrap (such as Glen Beck).
