Love reading your comments sections Rob, what a great group, love the enthusiasm. 👍
me too mate - some really great ideas
Robert, your channel rocks! I learn something new everytime I watch one of your videos.
Awesome! Thank you!
Many thanks from a man who will never really understand electricity BUT who is generating it based on a thorough understanding of structures. As I´m about to relocate to Zambia stuff like this comes in handy
Loved this episode. Wish in the future that you'd make a multi battery and how you would connect the 10 odd batteries (to get 3.5v) and what you would need to connect it to the phone.
Your phone battery probably says 3.7v ... If you cut open an old USB charger cord it probably has a red and black set of wires OR lookup the pin out for your phone charger cord...
Really happy to see you making batteries again Rob!
Fabulous. I wish we had guys like you as teachers when I was a kid. Such interesting projects and talked about with such enthusiasm . 😎🏆
you can use the carbon inside a used battery. crush it up fine. or just some cooper an iron in vinegar. it will be weaker but will work.... like the "Baghdad battery"
And when it's time to refuel the cell, draw off the electrolyte, add another piece of steel wool and let it sit a while to be sure that you've destroyed the HCl and use it to etch your circuit boards.
yes you could lol
i did not know you could do that.. : ) THANK YOU MATTHEW.. ; )
if burning coal sounds outrageous power source to you, how isnt it worse to burn steel (less available due to uses in construction)
You need to add h2o2 to that to turn it into fecl3 etchant, or just bubble air into it for a day or so if you don't have h2o2.
@@billymonday8388 I think that this is just an Emergency battery, and so the issue of using this is a moot point.
Although, if you have any suggestions for an alternative, please let us know?!
I mean absolutely no disrespect to you, and appreciate your concern for the environment, I am pro - active where the environment is concerned.
Namaste 🙏
Andrea and Critter Family. XxX.
Now....that was fun! I will have to make one with my young grandson.....this will really inspire him.
awesome mate - can i suggest the vinegar with the younger age groups?
@@ThinkingandTinkering Will do Robert.
Simply brilliant, sir. Thank you from Virginia, USA.
You are very welcome and cheers
Nice video. I think Al "air" batteries might be even better as they are more energy dense. Oxy clean works well to speed up the galvanic corrosion of the Al.
reminds me as a kid making batteries out of a lemon a copper penny and the lead out of a pencil produced enough power to move a compass needle with a few turns of wire wound round the compass
Cool, these are the things that are missing in the generations of kids today.
it is very similar but this will charge a phone the lemon battery won't
@@ThinkingandTinkering perhaps you could use lots of lemons lol
The Internet is like 70’s television today , 100,000,0000 channels , and and almost everything sucks , and documentaries take up time and attention , but built it / fix it videos are handy entertainment , Thank You very much ! Hard to hold my attention , I’m picky
Man that’s Seriously cool!! Need someone like you in all our lives
just found your channel, found this video while searching for your work on making hemp batteries.
This is a fantastic video and you really are providing a service to people by making these diy videos.
I think everyone should be shown this, this sort of knowledge has made a lot of young people interested in Science (Chemistry, Physics etc).
If every child was shown a practical application of this (how to charge a phone!) it would definitely get them paying attention.
Absolutely great video from Robert, peace from Ireland to you all, Tom.
I love the idea of making this battery from household materials! Bravo! The brick cleaner version is similar to the Fe/Activated Carbon cells I have been building using FeCl3 electrolyte. I would not be surprised if the cell you built is actually rechargeable. I have been experimenting with building sealed Fe/Carbon coin type cells and recently tested one cell that sustained 101 charge/discharge cycles, at 0.84 volts. During this this 3 day testing period the output actually increased gradually 7%. I don't think my cell is an air battery because it was sealed with a silicone gasket.
you are probably making use of the Fe2+ /Fe3+ redox couple mate - here, basically the acid etches the iron - given H2 generation and consumption of the iron anode I wouldn't try to make this a sealed rechargeable version if I were you - but an Fe2+/Fe3+ version is more than doable for sure - if you try FeBr3 then you will get the Fe2+/Fe3+ couple on one side and Br2Br-/Br3- redox couple on the other side too
"Air" is a bit of misnomer. What is really meant is oxygen and oxidation. You don't need air for that. For example, if you're making Al air batteries, Oxi clean mixed in water works well to provide the oxygen necessary for the oxidation process.
Maybe I missed it but what does the activated carbon actually do in his setup? I'm just trying to lean new things 😉
That's really usefull in an emergency. I'm not sure a phone will charge at 3V. USB spec defines 4.5V as a minimum and lithium ion needs 4.2V for the fixed voltage stage. Anyway, fun to try. I once showed my daughter the famous 2 coin battery with some salt water in between. She asked if it would replace an ordinairy battery. We calculated together how many we would need :-). Your's is a lot better.
thanks for the pointer mate - it would need a couple more then - the thing is the actual cell voltage of a well made cell like this is around 0.6V - but made this way it has a high internal resistance - the better you make it the less you will need
This is a great example of, "Knowledge is power". God is amazing, all the great things He has given us.
@ 4:16 you can hear someone giving it the full beans on a bike 🤣🤣👌 great video as always rob
Cheers Mate, you can purchase spare leads for reusable art pencils ,come in many sizes.
You are a fascinating guy Robert !! You really seem to enjoy what you do with batteries and heaters and electricity. Moreover you understand what you are doing, and make it understandable to someone who has no idea how this stuff works !!! I love your channel and can't wait to try making a carbon fiber heater as I've seen in another video. Thank you for sharing what you know and making it fun !!!!
Cool, now that you've done a video on a battery to make in an emergency, any chance of you doing a video on a "prepper" battery that people can make before the emergency and have packed away in a closet? I'd think something like the nickel-iron or the iron-copper would be good for that. Maybe make a paint with each, paint sections of newspaper, then roll up with the stixx machine. The only thing I'm not sure about, is how do you do the contacts. Any thoughts? And are the pottery glazes you've talked about the right form of iron and copper/nickel for the battery?
You can.Why not assemble it dry , eg inside pvc pipe then , pour in electrolyte when you need it?
Can't remember the #, but large 5 gallon bucket batteries were covered not long ago?
@@ShawynLeininger must have missed that one. Do you remember the chemistry? Zinc iodine perhaps?
Indeed and it was episode 1794
@@ShawynLeininger
I must watch that, thanks for the heads up.
We had the same hurricane in September 2021. I poured rain heavily for three straight days, then quit. It ruined our whole vintage (Goodwood-style) racing week.
if your area is forecasted to have a hurricane and you have the possibility of the grid go out, hopefully your prepared ahead of time to use a strong built wind turbine generator and lots of car batteries to store that high wind energy for later use when there's no wind.
Very instructive! Thank you!
how about some investgations on small scale generation using the tribo electric effect?
Ferric chloride produced here can be used for etching printed circuit boards, copper, brass or bronze.
pickle jars and rebar would be easily found around my house, and i think the pickle juice would work for an electrolyte.
Very cool. Thanks also for explaining how it works
Glad it was helpful!
This information is just so insane nice. Thank you. Me and my Boy Will have fun with New small homemade inventions. Thank you for sharing and Caring. One love from Denmark
Hi Rob if you made multiple pots to bring the voltage/current up to something usable would that be an issue with the hydrogen production?
Very good idea because the scrap value is basically nothing
My MacGyver tip for the day. Thanks!
Very nice idea. I have watched your many videos, and learnt different things...
ThNk you!!!!
Now i figured out how These Plant Pot Generators work, thanks for opening up that door for me, it was as Simple as a Potato Battery..
Glad I could help!
This is really cool..... It would be nice if you make a video on converting different dc voltages to 5v so that one can charge phone or radio or something else from other type of batteries we find in every household... Because I think everyone has different types of batteries like 12v or 18v lithium ion from electric scooters or drills and a car battery or maybe some AA type batteries.
nice idea mate - cheers
@ jay Patel
PROPOSED BUILD:
1. 5GAL PLASTIC BUCKET.
2. MAKE SEVERAL metal units in 5gal bucket, to meet your voltage DC. Several will fit.
3. Connect all wires together to get your REQUIRE voltage.
4 have a lid on it to capture hydrogen for cooking, welding, or red balloon signal to your friends.
5. Build to 6 or 12 volts to run through a battery charger backwards to get alternating current at the plug end as needed.
6. Use this for generation connect to a car battery for storage.
7. Drain liquid as needed to stop reaction/ or remove the array ( metal parts) to stop reaction when car battery is fully charged.
@@reypolice5231 nice solution mate.... Though I was wondering, which one is better? One giant bucket or smaller buckets all connected?
@@jaypatel-yj9gw
Further update:
The carbon should go in a sock or fabric sack to be easily compressed around a graphite rod. Why a carbon rod from an old battery would not work as well. Test to see.
Junk car exhaust manifold iron seems really available And free.
Mandatory all parts free, scavenged.
You will not be able to go to the store if it goes completely psycho. Collect all your supplies for multiple units. Starting now.
All your friends that you will depend on if things go sideways and they will will need your power build.
A friend in need is a friend in deed.
Have all your friends collect all parts. Build multiple units. Give your friends.
@@jaypatel-yj9gw
On a separate Matter
The people that get you parts and help you build, and answer your red balloon 🎈 signal are your t r u e friends.
Find out who you Friends are.
Excellent idea, I'll try it. I have Muriatic Acid in my shop which I use for cleaning and re-etching files and give that a go.
that will work awesomely mate - don't over fill your container!
@@ThinkingandTinkering Cheers Rob! Needed that info, we have that acid locally in Brazil.
Lots of other things you can use like Nail varnish remover (Acetone) or even some plant foods with Nitrogen, but you need to understand what Nitrogen mixed with Iron or Steel or even Bleach can get very messy, also you can make your own Activated Carbon using charcoal and a chemical like Calcium Chloride, but Lemon juice will work with charcoal to make active carbon. Finally note: do not let aluminium near any of this that I have listed.
fantastic!!!!!! Greetings from Patagonia Chile
Which one is positive and negative? Or does it not matter 😅 great knowledge as usual! Love it
Hi Rob, Would this also work if you laid a strip of steel wool, a layer of paper towel, then a strip of activated carbon felt, and a second strip of paper towel on top? If so could that be rolled up into a jelly roll and put in a jar with electrolyte to produce more current?
So this is the kind of battery that will start running out as soon as you pour the electrolyte in it and the rusting will start happening? Makes me curious if this is the essence of how batteries work, how does the other batteries keep from eating away until you connect them to your devices?
Depending upon the kind of steel alloy, I’ve head tritium fishing lures can help make a battery by causing the steel to resonate. It very similar to the radio decay themo reactor on the deep space satellite. If you can make ferric chloride there would be a few blade smiths interested in the by product for etching.
i am sorry mate - but that doesn't sound right to me I am afraid
@@ThinkingandTinkering beta-voltaic cells is what I was thinking of just couldn’t last nights recall it exactly. I’m also remind about the joy of predictive text. Coupled with sensory issues being no fun. Not the most coherent day on this earth missy paragraphs and spelling. But anyway
I believe there might be a research paper out there going into it .but can’t recall the source of the top of my head. I could be wrong, or just misread it.
If I remember the cobalt steel they were using to achieve, it had trace elements of manganese and chromium. Because of a know quality within that type of steels Crystal structure. The resonance disturbance allow the electrons to flow more freely in the matrix. may have been piezoelectric in nature. SpaceTime crystals are often made from this steel. Please correct me if I’m wrong and a little wayward here. Sorry for any confusion from my poor use of English. But with the ferric chloride made in the vid it knows as an etching compound blade smith’s it extensively on forged in fire. Thought I needed to clarify and clear up any confusion I may have caused.
@@jasonhaymanonthedrawingboard thank you for taking the time to explain and expand mate - if you can find the research paper I would certainly be interested in reading it - all I really need is the DOI - cheers, Rob
US20070286324A1 it may not be the exact article Id seen but it’s pretty close. Thank for the google Patent hint. Dating all the way back to 2007. Just goes to show how long the idea has been around.
@@jasonhaymanonthedrawingboard Just wanted to say "Thank You", and well done for taking the time to clarify your comments,
I have a couple of little cognitive issues and I am truly impressed by your tenacity, and finally explaining what you meant to, so well, & fantastic ideas, many, many thanks!!
Namaste 🙏
Andrea, Jasper Mutt , & George and Rudy the Pigeons. XxX.
Ps, Thank you so much for finding the article, I am just about to have a look. XxX.
Brilliant video! Thanks from London 👍🏴🇬🇧
Nice! Mate pretty please, what would happen if you integrate your best blade design into a dry hho cell so each cell powers eg 4 divides(urea), and how long will it run after turning off? Cheers
Time for some humor. Can your show us how to create THC in a vacuum? Please! Love the video.
Love this video. So incredibly practical.
I have a suggestion for a follow up video to this. Showing an easy way to actually connect your phone to such an emergency battery without harming the phone. Just a thought. As always your videos are always first view for me. Keep them coming.
Great suggestion! - but if it was me I would just use one of those plug in chargers - all the protection electronic needed are supplied for a couple of dollars - all you have to do is connect the positive from your battery to the button and the negative to the side clips and you are off!
My new favourite channel for sure. Thanks for all the videos
Could we take this a stage further & capture the hydrogen in a dome with outgoing tube providing fuel to burn?
I’ve always liked cardboard boxes , handy , because of you , now I’m collecting things I never did before , and I’m putting them in cardboard boxes , told they were handy , I save moms from her home too l and I’m always running out of cardboard boxes
This could be where an Earth battery could be investigated . At a workshop I went to they suggested that biochar in two trenches running parallel 500mm apart had a voltage difference of 1.5v when connected together . With biochar in the soil , iron in acidic soil and moisture . Biochar could be made with the help of your gasifier made a while ago to run a motor
@ martin bonner
May I ask you to explain this build further?
I have seen earth battery builds before but never with the bio char as described.
@@reypolice5231 , I’m not a soil scientist , but the way I understood it that two trenches eg 300mm wide , 300mm deep x 500mm apart , trenches filled with biochar , moist soil with an iron content (adding iron chelates , guessing) . Anodes and cathodes between was supposed to have a voltage of 1.5v . Could these be hooked up in series ?
As I said I’m NOT a soil scientist ….. just the way I understand it ……. Something to do with Cation Exchange Capacity
@@martinbonner8626
Rob should how he did that with just a 4inch plastic pipe a piece of iron and a battery carbon rod. I think he use an acid? I think he got 1-4 volts?
Find his video. I think he said there was more in the paid members section.
@@martinbonner8626
Also look up YT channel Patrick Kelly.
He goes over the 1835 patent in detail with links to website for full download of all his stuff.
What he showed was very well explained.
Website also very good.
This was used for telegraph lines in the US civil war covering many miles.
We never needed anything else.
Look for my other comment in this thread. I explain battery storage, And answer other people questions.
Hope it helps.
didn't MrTeslonian do that?
Wold carbon rod work as well as the pencil lead? Model boat and plane Hobbyists use carbon rod to build the frames and control rods.
I suppose cleaned plastic Yogurt cups ought to do well as the container; we have those in plenty at my house.
I take it that the graphite refills for a mechanical pencil will work too??
You think you could charge up some capacitors to increase the voltage?
I like kinetics. How about arguing a case of full scale windup cars ?
Hi Robert,
My source for activated charcoal is dollar or pound store knock-off Brita-style water filter cartridges. They have quite a bit of it in them. The hydrochloric acid is sold here in the U.S. in hardware stores as "Muriatic Acid" with the masonry or with the paints and varnishes. Other than hardware stores it can often be bought in department stores in with the swimming pool supplies.
I love the channel and your positive outlook is uplifting and inspiring. You give the unmistakable impression you are having great fun, succeed or fail.
Also toilet bowl cleaner can be hcl.
nice tips mate - thanks for taking the time to post
@@selkywaters That's right, I forgot about that.
Would the carbon rods used in stick welder's for creating an arc heater for brazing & soldering work rather than the pencil graphite much more robust and about 18 inches long give or take... My old buzzbox came with a holder just for that function. It was developed for farmers and ranchers 220- 230 in but in a pinch if one power leg is out you can use it on 120vac at reduced amps really cool old welder even has a battery charge feature for 6 vdc car/ tractor batteries... Still works like a champ..temp was rated at 3000 degrees' F' if I recall correctly...
That's really awesome now I know what to do with my fine iron shavings from my lathe LOL I'm a lathe operator at least on the hobby level I have a old Logan 10-in lathe that I used to make a little side money I've been working on the lathe in the mill for about 17 years now and I end up with absolutely kilos and kilos of very fine iron shavings maybe I will separate out some fine regular iron shavings and put them in nylon socks for this purpose I do lose power quite often in the old neighborhood that I live in.
I've always got a gallon or two of hydrochloric acid on hand
Fantastic as usual, a small point though, 3.5V would only charge a phone battery to about 40%, you would want to get up to 4.2V for maximum charge of Li-Ion.
cheers mate
40% is better than none.
Make a few to reach your 12 volts to charge a car battery or cigarette adapter.
So you would need 12 of these instead of 2.
I am thinking Brillo pads!
Sandy, Ireland
Awesome, and maybe I missed it but how many milliamps are produced here?
I found a easy way for a emergency lights went to dollar general store bought mini lights with a battery pack put in a mason jar light a small room for hours cost less than 4-5 dollars with batteries
nice tip mate - that would work well - this is kind of for folks who didn't get round to doing that! lol
Hello Robert !
Awesome, thanks Rob.
cheers mate
That's cool thanks
Does this mean if you build it such that the iron is replaceable you have an nearly un limited battery the iron goes in solution right? If you get the salt that decompose with heat (the vinegar one would be iron acetate and would decompose ) you would get a renewable energy supply just decompose the salt with sunlight and fresnel less and you are good to go
Brilliant Thank you again.
I am a very simple man when it comes the world of electric , could you possibly show the next stage of hooking up the emergency battery to the phone charger so's i can get an idea of the principal process . regards
We've got loads of liquid chlorine for the pool so... Sodium hypochlorite I guess... Perhaps that would work as electrolyte in a pinch too? 🤔🙃
to be honest mae - i would think so
@ Ollie be
It may work. Only way to know it to test it.
Or go look at a bottle of brick cleaner and ask for the M.D.S.S., Material Data Safety Sheet for what's really in the brick cleaner at the store.
Pickling vinager is at 6% regular vinegar is at 5%.
It's way cheaper than your pool chemicals.
@@reypolice5231 I may test it! My curiosity is because we've literally got gallons of chlorine right now if our hypothetical hurricane comes and not very much vinegar! 😅 I'm not using my balsamic. That's for salad.
My understanding is the active ingredient in brick cleaner is hydrochloric acid, and that Sodium hypochlorite is like that but a gas concentrated in water somehow. 🤔
We had a good chemistry teacher when I was at school 25 years ago but all I remember was setting things on fire and making rockets out of cola bottles 🤭🤣🍻
When I was a kid I used a lemon, some copper pipe, a nail and wire to light up a little globe
yep - works well and produces a milliamp or two - this produces a lot more
Well I enjoyed this video, thanks Robert.🆗🧐☺
cheers mate
if for any reason you go back in time to 100BC, how would you make such battery? It would be easy to get all materials except for the graphite... what could you use to replace the pencil led?
Out of curiosity. if you use a bigger container and larger componets, would it make for a larger chemical reaction?
Like generating a higher voltage or lasting longer. Or is it a set defined voltage per reaction.
I WONDER ... with the north & south poles somewhat moving toward one another(my guess, toward Africa), and maybe becoming more like a horseshoe magnet, if the value of a ground battery might change?
What this Rob? The MIB mother in Law Battery. Or Men in Black (Battery). Very well done.
lol - like it!
Considering I have no wires or clips lying around my home like you do, if I ever were to make a chain if these batteries, how would you recommend I do it? I'm particularly naive about how to connect it to a cell phone recharging cord.
Great Video Sir
cheers mate
I have been watching your videos for about a week now and I just realized I hadn't subscribed yet, that has been remedied(sorry about that!) as I really like your videos you get right to the point most of the time and I like that ! thank you !
speaking of home made batteries I have a question for you.... I want to make a acid battery
that uses dissimilar metals, but I don't know which metals are the best to use, if I remember copper and zinc were the best voltage producers per cell I plan to make a large battery that will last a few years at a time that can power my 2000w inverter 12v input 120vac output
this may cost me quite a bit for the metal but I think it would be worth it to have power when the electricity goes out. i figure 12"square plates per cell and enough plates to make 12 volts.... what do you suggest ? thanks in advance !
is there such thing as a battery where the materials do not get eaten away?
Awesome!
Thank you soo much!
And how we do 7:42?
This good man is my hero!
wow - thank you mate
AWSOME...
is it possible to build a lead acid battery in a large container like a bucket or drum with big plates?
It might be called "Brick Cleaner" in England, but what is in it?
Excellent, thanks.
Glad it was helpful!
I was looking at earth batteries a while ago....not made one though...just came across the idea 💡
Did you use copper wire to wrap the steel wool? Would a Brillo pad work in place of the steel wool, is basically steel wool impregnated with soap
no steel wire - I did say in the video - copper won't work as there is a displacement reaction between copper and steel - I don't know about the Brillo - but it would be worth a try - though I suspect it will froth a lot
I tried to make home made HCl using bleach and sugar. It did seem acidic.
Next stop Cooked potatoes as a battery. Some videos are on YT.
nice idea mate - cheers
Robert, this could be a product sold as a kit. A replaceable cartridge system.
for sure mate - but there are better emergency batteries and we have covered a few the main thing here is it can be made from readily available materials that are just in most peoples homes and yet produces long term useable power
How do you make Activated Carbon Insoles into Granules?, also didn’t get where you said it was on cookers?
The vent fan in the hood over the cooker usually has an activated charcoal filter.
a blender?
Awesome
I have a question sir. If battery is a chemical reaction between anode, cathod and electrolyte. Then what is solar panels? Is it also a chemical reaction? What is being eaten up in solar?
Brilliant thanks man 👍
glad you liked it mate
Robert, what do you think of making multiple batteries like yours in 5 gallon buckets, or 55 gallon drums and hooking them to gether?
Robert you should show a JOULE THIEF CIRCUIT along with this Battery. Show Building the Circuit and hooking the Home made Battery to it and show it running LED's and charging your Phone. Just a thought. Thanks for bringing back your Chemistry back ground. I do like your Chemistry Robert.
i have done it mate a couple of times and a full explanation video for how the circuit works
Well I'll look for that Video. Thanks for your rapped reply.
I feel like you should collect the hydrogen that is generated somehow. Throw it into a small motor as a fuel and you can generate even more electricity and make yourself some water as well.
