Junk Yard Battery Contest

10/15/2007 5:52 PM

As a spin-off from another thread... It's the CR4 X prize for the best 'junk yard battery'

Rules ..

1. Cell.

2. must be made of household / easily available materials.

3. Winner is best mAh x 'mean on load voltage' from full charge (divided by the approx cost in $ of any components which need to be purchased if greater than 1.)

4. In the case of a tie the one with the cheapest, most freely available components wins, or the simpler design (or the greatest bribe in cat food).

5. Anyone blowing themselves or anyone else up is disqualified.

6. Prize 10,000 GOOZ cards from Hendrik's special stash...or maybe some of that Homemade cider from the blog? Loads of kudos and maybe a Nobel prize?

7. Technical details must be published, to allow verification but any I.P resides with the contributor.

8. Further rules may be added if necessary.

The aim of this is to hopefully come up with a useful 'green' way of storing useful (but probably small) quantites of energy, or at least add a bit of humour to the world!

I'm going to splash out on something! Who can be first to make a working battery?

The splash needs to be on two dissimilar metals in order to make a cell......

So a big fat tank in the loft and a micro pump-turbine would be disqualified?

Errr Dunno, on second thuoghts it needs to be something with higher specific gravity and less viscosity. oh and low cost and environmentally friendly.

just can't think.........

Does this help ? I think some kind of carbon offset should be allowed here. It's not fair to folk in damp climates who want to go Green.

Kris.. don't be a lemon...although on second thoughts....

I'm stuck at work...I wanna go home and try by bleach/cat piss electrolyte..or maybe lemonade? This is going to be fun.

But how to I connect a wire to an alluminium beer can?

Who will be the first to produce a voltage of some sort?

If I have 'silver' coins in my left pocket, and 'copper' ones in the right, am I in mortal danger ? Well, accidents do happen you know. I tried getting 'Sooty' to use old Chinese take-away trays filled with bentonite, but she just wouldn't go for it. I suspect she knows more on this subject than I do.

< don't rub salt in my wounds, or I'll have you for 'assault and battery'. Mwahhhh ! Wouldn't a cat-tray battery be kind of cool ? It might be able to power the cat-flap occasionally.>

Either way yo've probably created yet another battery - they might now be in opposition.

Brings a thought to mind, what is the difference between a battery and a thermocouple?

Good idea for "the professor" on Gilligan's Island, who just needs the battery to work for a few minutes so he can transmit to that plane approaching the isle.

If the can/connection gets immersed in the electrolyte (typical), then corrosion between the connection itself will become a high-resistance connection in short order.

Nonetheless ~ it's an option ! (just keep the top/connection in-the-dry)

Results....I'm putting down a marker here!

Beer can, copper pipe, domestic bleach with a good bit of common salt.

About 500mv initially dropping to about 280mv.

I happened to have a battery charger to hand so I stuck some juice into it for a few seconds... mmm nice fizzing, removed charger. 600mv ! rapidly dropped back to 280mv.

I realise that some of you may find the precision of this experiment a bit daunting to live up to, but come on who can beat my 280mv... I've still got the cat pee in reserve!

And let me guess.....you bought the complete package and are now running your car/home/everything else on water alone (Hydrogen), right? and all for the small price of 300$!!!

The funny (very sad, really) thing about this is that although the "secrets" won't work, the scam surely does and I am sure they are making lots of money from this.

At the moment Rick, I am one step ahead! Due to my flamboient lifestyle, I now find it necessary to run my car/home/everything else on thin air! Maybe this would sell! Give me all your cash and you too could run on thin air!

OK. I'll bite. What's the difference between "air" and "thin air"? Does this mean that you have to do the experiment in the high mountains? More ions per sq m? Less back pressure? (Just pulling yer chain).

OK, I haven't read all other posts, so I will assume that this is the first challenge question to your rules: Does this HAVE to be a rechargeable battery or can it be a disposable battery?

I don't think you're clear on this point.

Rechargeable....

but anything will be of interest, especially if it is made of junk.

Marks awarded for action, entusiasm,originality,creativity....I'm just hoping maybe we find something new.

I know this is highly unlikely as it's doubtless how the pioneers started...but we won't find 'owt if we don't try.

It's fun with a serious twist....look upon it as a Gin and Toinc!

Well if stuff gets eaten up while discharging, I'd say that would be a strong indication that it was disposable.

OK. Del, help me out with this one. I went to Wikipedia, to find out more about the basics of batteries. It shows a nice diagram of a zinc/coper cell made of two half cells separated by a "porous disk." However, no matter how hard I dig, I can't find any information on that damn porous disk and what it's made out of!!!

Any knowledge or place you can point me to?! "HELP!!!"

Verm, I would point you to the rubbish bin...

won't cardboard be suitably porous? Blotting paper (do they still make that stuff)?

Coffee filter paper. Piece of old knickers. carpet underlay. packing foam...?

This is a 'junk yard' battery the clue is in the name!

Well may your emoticon blush...shame on him...send him out scavenging immediately until he returns smiling!

No, not the knickers, they're absolutely essential for filling the holes in the garage/loft/under-eaves cupboard and other places of draught entry too numerous to mention. Sox too (not the cat).

Is this beer can full or empty? It would be a shame to waste a can of beer --- if it's full there is a violation of the rules, 'cause beer isn't JUNK.

Re: Junk Yard Battery Contest

11/24/2007 8:55 PM

Summation today 11/24/07: I put a commercial 9 volt battery in my Sperry Multimeter and poured vinegar, or ascedic acid, stop bath dilutions, or salt water, on strips of copper in glass or plastic jars or bottles this afternoon.

At first pours I got .431 as highest read on the hand held test to the meter on the copper ascetic acid bowl, which was the third construction.

Made variations using aluminum and copper. Using same for anode and cathode in every solution. Let all sit for a few hours after initial meter tests and at last test got nearly 2 volts from 5 cells.

I am turning towards more and more common wires and connectors. My next set of experiments will use zip cord, or lamp cords and beercans and copper.

I truly am interested in wiring up toilets to see what we can get out of them.

The Potato set of stab wires I left at my brothers house where they were drinking beer and watching the fire had only got to .016 by the time I got it there.

Some of the great devices around really do run off of really low power as far as I know and having electrode and cathode stab sticks to stick into the walls around to run what ever you have to, might be fun and possible.

That Electrochem Company and Exide and Ray O Vac, are far beyond my re-inventions. But I hope to catch up and surpass them at least as far as low tech and systems go.

2. must be made of household / easily available materials.

Dig through that pile of old computers and find the biggest capacitor you can. Put it on the window sill in the sun for a while (chase Del off the window sill if you have to, he'll understand). Caution: DO NOT TOUCH (OR LICK) THE TERMINALS

My bit of copper pipe in the beercan full of bleach/salt has some nice pretty greeny/blue stuff around the end of it now! But is still sitting at ~400mv. Once someone raises the bar I shall try some other stuff and see if I can compete... (my jar of cat pee is filling up nicely now )

There's no danger this thing will tip over into a beard-growing competition is there?

There is every danger of that unless someone has the enthusiasm to try a few common household items....

It only takes a few minutes and a DVM.... can of coke and a pencil...c'mon someone.

raise the 400mv bar and I'll try and beat it....

If I have to come over there and tell your Mums there'll be trouble..

Now get on with it, else you can all stay behind until you've made your batteries!

I get the impression that almost any liquid/metal combination produces a result, but I thought cans were laquered or treated inside these days? If free-gassing is a measure of efficacy I think I'll make the basis of my first experiment a can of beans.

PS, just a thought but oughtn't we to be using a standardised load?

Grrrrrr Ftttzzz hissss!!!!

This might be relevant if anyone was doing anything other than thinking about it!!!...

' but I thought cans were laquered or treated inside these days?'

(Not really having a go at you... I was just hoping we might have seen some results by now! Appologies ensue if you have a shed full of test batteries on test!!)

My beercan worked fine

Re: Junk Yard Battery Contest

The mention of such things as 'beards' and 'Garden-sheds' is seriously troubling me. Much as I enjoy a nice pint of real ale, I will have a hard time keeping up my usual self-control if anyone announces themselves to be a card-carrying CAMRA member. I am still reading with interest Del, simply enjoying your frustration at the lack of action < falls of keg laughing>. At present, I am split between trying something involving copious amounts of lemon juice, and some kind of retro earthenware pot. I may yet enter this project, but it's currently second runner to the supporting wall I'm taking out. Does any one know what an RSJ is ?

Incidentally, I now have 573 empty tins of 'Old-speckled Grotskins Premium', caringly saved since this thread started. Will I be excluded for constructing a battery rather than a cell ? As a possibility, I am prepared to swallow zinc supplement tablets, but I'll be darned if anything will happen with copper at the other end.

Mythbusters recently did a "Battery" using some of the pots you display, it worked, gave about 0.8volt per cell if I remember correctly.....

I am too busy renovating to make a battery at this time, maybe later, sorry.

I see you found the Babylonian beer bottle battery website.

Del vetoed tree jokes or I'd have (here I am resisting the temptation to say "palm off on you"!) discussed the possibility of a truly green battery - a cocanut with inserted electrodes. The milk/juice should be acidic enough to give a bit o'spark.

It took me some time to twig what you were on about! So another thread branches off at high speed.......Go mango!

Stoooooooop, We seem to be heading in a downward direction very quickly! Only one thing can save us!.....A sensible question! Any takers on 'The electrolyte best suited for a battery and why!' or 'The best metals suited for the anode and cathode!'

Dels piss is getting ready to show us all up and we haven't got a contender so I will take it upon myself to go to the kitchen and make a battery now!

Blimey you are raising the bar and pushing the envelope here!

If I'm to compete I may have to secure funding for another can of beer! I must draw up an action plan and timescale...better do the risk analysis first too!

Nah... I'll go in the shed an pee in the beer can!

Ha, Pee in a beer can eh! Well I have salted my solution and changed the steel to zinc! The steel nut has lost it's zinc coating, so I've gone for a zinc pencil sharpener! (Not zinc, but magnesium I think!)

Washing-up liquid?????? No! Must've at least been Palmolive!

Seriously. what benefit I wonder hase the Pal... I mean washing-up liquid brought? Better wetting of the electrodes?

You never know until you try! What is your battery up to?

I've gone on to bleach, and the numbers are climbing! 0.6v after 20secs, 0.72v after 20 more secs.....looking gooood

Still at work .(but no working too hard )

A quick 7 holes of golf after work before it gets too dark. Home to cook the dinner (strir fry). Then out to the Cat shed !....

The washing up liquid will increase the conductivity of the electrolyte....

(At work we measure detergent concentration in comercial dishwashers using conductivity probes. )

You only do 3 days a week! Lots of time to experiment!

By the way, 0.84v after 3mins

Update.

My beer can is steel.

I tried an Ali' can and it does seem to be insulated, as suggested by Wrenched.

I tried some lemon juice...but it got diluted with unmentionable fluids before I realised the Ali can was insulated.

I reverted to the steel can and found the Zinc plated screw gave a better result as per Mr Truman B.

Still couldn't get upto his high voltage....grrrr...I got about 0.5v

My original battery was pretty flat but had made some nice copper salts!

More play another day.

It's settled at 0.66v now for the last few hours! The pencil sharpener is really black! I may try to catch the gas that comes off! This could be used for something!

That's it, It's dropped down to 0.12v! Bring out the next idea! Looking at lead tubing and copper tubing at the moment, all inside plastic tubing! Any suggestions on an electrolite?

Re: Junk Yard Battery Contest

"Lawdys"...! Never would've thunk so many 'contributions' to weed-thru for so little gain...! "Suggestions on an electrolyte"...? How's about spreading-out some more of the fundamentals, first.

[[ Not to burst anyone's bubble in-any-way-to-any-degree ... but please do realize that most ANYTHING that any of us was to attempt has already been tried by those who are either in-the-business ... or college chemistry class "wanna-beez".]]

For those who haven't already sought-out and viewed:

Dry Cell Construction & Operation View all tabs... The reason for "pulverizing" the anode and cathode materials, nowadays, is to increase the (usable) surface area of each of the electrodes to improve both the max-available current and the longevity-efficiency (total amp-hrs).

In a corrosion-cell-battery, electrolyte is needed because free electrons won't (read: "can't") travel through pure water, or air, or so many other materials. They can only travel through such materials riding "piggy-back" on an otherwise positive ion. The sulfuric acid in a lead-acid battery (or citric, or other acids) contains many Hydrogen ions (the more acidic, the greater the density/concentration of said ions). This is why acids make great electrolytes.

Your challenge is finding an electrolyte that won't contribute to the passivation of either-or-both electrodes in the cell. Passivating (either anode or cathode) causes voltage drop between the electrodes. You want your electrolyte to assist in maintaining activity of the anode for the life of the cell ... or (in trade-off fashion), to promote / contribute-to that "reverse-reaction" necessary for re-charging of the cell.

Sodium (+ metal ions) make great charge-carriers just as Hydrogen ions (H is an alkali-metal) ... just as the potassium ions in that potassium hydroxide used in the Energizer (the link above). In seawater, when zinc is used as anode material, the chloride presence helps to OFFSET the passivation that would normally be caused by carbonates and dissolved carbon dioxide.

Try working with what we know ... and take it to the NEXT level.

Best of luck ! {sorry... I have YET to find time to dilly any further with my carbon plates}

We call that cheatin' in these 'ere parts.

But seriously... actually thinking is the next step...I was initally just trying to drum up some interest.

Mind it's still a 'junk yard' battery we are after not a copy of mr Duracell's best.

PS.

We know this but ..if enough people play we may find something new...on the Monkey and Typewriter principal. (Now where did I put that monkey? ...maybe Monkey pee is better?)

Previous encumbants of the house I grew up in kept gibbons, but not their pee.

Had an excellent wine cellar instead.

The Gibbons were catheterized in some kind of evil experiment. The previous owners left to a new secret location and forgot the sample jars.

< that's purely hypothesis of course> I was clearing out a garage with a mate, and his nephew spotted a can of beer. " Wow, this was made way back in 1848" he exclaimed ! I probably got the date wrong, but it was one of those lagers that proclaims it's heritage on the label.

I've been hunting all day for stuff and all I have found is a bit of copper tube and a bit of steel tube! Time to experiment again! The monkey piss will be a bit difficult to come by here so I've been feeding my dog bananas! Hope to get the same result though!

Very glad to hear someone's propping up the canine corner here. Tried to get either of ours to piss into a jar last night. They're usually sooo accurate???

SHhh. Marking this off topic in the expectation that Del won't notice the the 'C' word

The trick is to put a container in a handbag and let the dog do it's trick! My dog has a fetish for handbags so I tell everybody who comes round to leave them closed and out of the dogs range!

Why would Del mind the word 'corner'? When I finish reading this lot, I'm entering the competition. Even if too late for consideration for the door prize, danged if I let this be the end of it. Del deserves better. Or at least more if not better...

"Guilty", insofar as seeking a (good) link to battery construction... but, having already known all this since my corrosion training began (at an extension of Amarillo College ten years ago), my posts have simply divulged material that I have taken for granted for many years ... thinking it to be, perhaps "phorgotten phenomena" to all of our esteemed gradumatates herein.

The "10,000 monkeys at 10,000 typewriters" principle is what encouraged me to insert the disclaimer as I did... most certainly someone could arrive at a "Eureka!" moment. {I truly hope that someone does!}

Meanwhile, I would hope to see more real ..."let's not all rotate turns reinventing-the-wheel"... INPUT. Personally, I'd like nothing more than to see something GOOD come of all this. IF NOTHING ELSE ~ as one of my previous posts hinted at ~ the U.S. uses a sinful amount of electricity to turn bauxite into (pure) aluminum. And in all-too-many locales (including Lousyanna) people are encouraged to NOT recycle, even though it would save us TONS of cash every day! "Lez jist berry all dat crud... ain't no poynt whazzoever in tryin to sort it out!"

If a truly useful "BackYard-Battery" were invented that actually made USE of all that free energy locked-up in the aluminum, gazillions of beer cans would be heading to the backyard, instead of the highway medians!!!!!

It's great isn't it - and think of all the fun making it ! " Yes dear, but I've just got to drink a few more cans". I didn't read the full article on this one, but there's plenty that Google's for 'beer can solar panel' and similar. I don't want to hijack Del's great project to power an LCD clock*, but this does have potential, whatever you do with the output (). This might even get funny - Del's 'piles' versus my 'couplings'.

*Only joking Del ! I want to know what you can make your cell do in 'real' terms. Mine is currently padded, but I'm still following !

Hee heee... C'mon Del, Tell me more. I want full blown diagrams, detail of how your measuring your cans output, what ( if any) load is attached etc . How can I compete if ya don't tell me in full detail. Right now I have an old water cylinder to dispose of ( ie ex-CH size). I could use this as a water butt, junk it, or fill it with something evil and foul smelling. What can I get that's cheap to fill it with and what could I use for electrodes ? Would I kill the national grid if I attempted one of those energy feedback schemes ? What shall I do with it - Water butt, solar heating project, or insane chemical cell experiment. With a thing this size it mat take a while to fill with junk chemicals, but I'll pursue if tempted. No way is 'Mr Scrappy' getting his hands on it for free, but the wife is giving me hell cos it's sat on the landing at present ! Give me a suggestion.

Ah..no...the water cylinder is for the solar heating project.

You remember..you are going to use your central heating to radiate heat out to the sun in an attempt to stop it cooling down and dieing!

OK. So I figure if low cost or free gets you extra points, theft should get you even more points. Right? Don't say no - I don't mind being a felon as long as it's for a good cause and extra points!

What if it fell off the back of a truck?

Re: Junk Yard Battery Contest

I knew you'd remember ! But what do I do with it ? Now I have a dilemma. Having finally ripped the guts out of my house, I have a **** load of stuff to dispose of or use, a new heating system to install ( cos it'd getting dammed chilly now)- heeeeelllllpppp. You're can battery ain't gonna help me ! Actually I do have a plan, but using the junk could be fun.

The central heating is ripped out, I have floor boards that the average seaside amusement 'wonky House' wouldn't believe, and you hope for me to make a battery ? I have enough spare copper lead iron steel, to feed China for the next zillion years. The spares will be chucked in a corner, but they ain't gonna be used any time soon. I had to squat on my bended knees burning off some of that old Victorian piping- lovingly fluted into the next bit of pipe. These fums must be getting to m head - back soon, y'old mangy cat.
