- A 4 farad 1.2v graphene supercapacitor and how to make it step by step. You can buy kits and materials for your own experiments as well as my ebooks from our webshop at secure.working...
My left ear enjoyed this video...
that'll be the one to use then
Uh, that was left? I've reversed my speakers then.
I thought it was 1980 mono tv
Hey guys take it easy just enjoy....lol
I did enjoy it, very much actually. But only in the left ear.
People may be wondering why you're laughing. Not many years ago a one farad capacitor was pretty much unthinkable on a practical level. To be able to make one in 5 minutes using pennies of common materials from your house is unimaginable.
It's the electro-chemical equivalent of being able to make a smartphone in your tool shed for $5.
really nice way of putting that mate - cheers
You can make a smartphone In your toolshed for 5 dollars
Davey Hi his laugh was contagious. haha
Standard capacitors of that size are 1,000,000th the power.
I remember solving physics exercises and having to restart calculating from scratch when getting a result in farrad class because it was unrealistic and when you get a result not in uF or nF you're almost certain that you've made a mistake and have to start from scratch.
I know I've said it before, but truly love watching your videos. Mainly because you are such a big kid!!!!😜😜
+Eflat Productions lol cheers mate
I don't know if I would word it that way as I wouldn't dare risking to offend him, but I would agree that RMS is having way too much fun! I'm thinking he must be single, but if not I'd like him to explain again how he exfoliates graphite in the microwave.... without getting scalped by the wife that is.
lol - i am married mate - there are quite a few videos on microwave exfoliation 'a' does a really good one
Thank you for sharing your knowledge.
+John Allen cheers mate
LOL your laughter at the achievable scale of these things despite almost no care or precision taken, is infectious. Think I'm going to have to go back over some of your earlier vids as a primer and give it a go at last. I've been merely observing for too long.
+TheBaconWizard good man - let me know how you get on
+Robert Murray-Smith I will do :)
+TheBaconWizard cheers mate
@@TheBaconWizard Well, it's been three years now? Guess the capacitor roasted the bacon wizard.
STOP🤨🤨🤨🙏🙏🙏. Be warned… if you subscribe and try even ONE. You’re gunna get got. I have a whole kitchen slowly turning into a laboratory and a gsmall group of neighbours that are convinced I’m “not normal”.
Also… your going to have (to use the Australian vernacular), a “shittonne” of fun 😂😂
"kitchen paper, because it's easy to get hold of" good times, good times.
Bbbbbb
This is one of the most important videos ever made! I am damn serious about that assertion.
Damn right! Now how about this question? How do we know that the GO is actually graphene oxide? That would certainly account for why the AC does so much better, right? We really do know that the activated charcoal is as advertised. The GO....not so much. We really need a bodged together Raman Spectrometer in here!
Robert, I know this is an older video, but they're all such excellence & I picked this one to comment because I get a kick out of it every time.
You sir, are the greatest. Absolutely the greatest individual Ive encountered. I wish I could work along side you, that would be fantastic.
I greatly appreciate your work, the simplicity in which you're able to convey the information to your audience, and I too find top humor in the things you have a good chuckle about.
Despite the simplistic conveyance, your passion for the things you do in science is always very clear.
Thank you for the experiment ideas and knowledge, and know that some guy in the first state of the US is thankful for what you do and finds great joy in your videos.
Thank you, sir!
This is all new to me,
I'm fascinated watching your experiments, particularly the Hemp and Graphene battery.
I wonder how many businesses (big and small) have approached you?
Anyway, keep up the great work, thank you from Australia.
The content of the video is so amazing, but the quality of the video is so blurry it's really sad. We should all pitch in and buy you a better video camera so we can really see the details of what you're doing.
And better micro (two channel at least). But all an all video is great!
I didn't even notice lol
I'm using a 13 year old thinkpad with a 1024x768 display
A closer view of the detail things would be excellent. I often watch from my cell phone and the RUclips app will not allow me to zoom in or at least not that I have found. I used to be able to zoom but about 8 months ago something changed and I can't anymore. Bummer!!!
So I true. I second that emotion
When he announced "4 farads" it genuinely made me smile. The future looks bright.
awesome mate lol
Personally, for an acidic electrolyte, I'd use gold foil, very low resistance and absurdly high conductivity, and almost nonexistent reactivity
Would cost a lot
Gold leaf ;)
Gold has low overpotential, the working voltage will be less than 1V in that case.
R M-S, please buy a microphone--the echo in that room is quite distracting.
ruclips.net/video/O6ZsqFWXOaA/видео.html
instead of telling him to "buy" you can buy and send him with mail. Seriously people who complains about things cannot be technical minded.
Robert thank you for the video and your echo is very fine i liked it . But seeing the values on the device and seeing the configuration of cables would be more interesting :) thanks for info now i consider the posibility of building supercapacitons instead of classic lead batteries :D
I thought no one was making videos that perfectly explained these convoluted things. It makes me happy that people are showing how to make these basic parts of very cool new technologies
cheers mate
New lol 😂😂
So if I am understanding this right your 4 farad capacitor, translated into size comparison to those capacitors you find in a clock radio for example, would have to be the size of the Kitchen roll you have there. (depending on the voltage used)
sounds about right mate
Thank you so much for not editing the waiting period out! LOL
By the way, 3rd viewing. We all need to watch at least 3 times.
It's good to watch these old videos from 2016. Full of great info :)
Fantastic, love all your work and videos, your attitude is spot on, you are without a doubt contributing in no small way to making our planet and lives much improved. As your experiments prove, one guy can do some amazing things, with a little ingenuity. All the very best to you Robert and your team and everyone.
If you like DIY you can do this:
kudelkin.info/en/Valzy-en.htm
So one can make their own width and add even heated rolls.
Superb video, outstanding results
Imagine banks of these to fill a building for storage of PV solar driving inverters, better yet no inverters and use the D.C.directly
+Craig Nehring that would be cool - get building lol
Hi I have a question about your carbon powder and binders you are covering in this video. When it comes to the acetone method, are you mixing just acetone by itself with the carbon powder or is there a third additive that is the actual binder to this formula? My apologies but I wasn't quite sure what I heard in the video. My last question is about the current collector materials in this demonstration. Did you use the same current collector materials for both capacitors? If I was not mistaken in what I heard you describe I think you used graphite foil for both capacitors. I'm aware that on one capacitor you used activated carbon and on the other capacitor you used graphene oxide if I heard you correctly. I am wanting to try my hand at this so this and you have covered this in detail and I cannot thank you enough for sharing this information with others. Take care and have a Merry Christmas, Flash001USA...
How does this only have 125k views......
RUclips CEO is a SJW-Femminist
SJWs dont like useful videos ;D
Yup... it's pretty damn impressive. Congrats man and
thanks for sharing. Regards from Argentina!
And there was I, thinking that you'd need all sorts of clean-room conditions and highly technical and expensive processes. Thanks for that, subscribed! I shall be watching a lot more of your videos!
cheers mate
its all about how u use basic science to do complex designs
no fancy stuff required
if u have the mindset and wisdom u can do anythink
i agree mate - well said
Thank you for this video! It is exactly what I have been hoping for in the context making carbon based energy storage. Right now I am puttering with making graphene, and I think I have a couple grams of it, but it's still a little short of being in a usable form. My research in this stuff in forced to take a back seat, right now I am putting together a farm business and that takes most of my mental focus.
I hope to be able to power an electric bicycle with a much larger unit in a couple years, after my LiPoly expires. I think it would be great fun to see one of your large super caps on a bike, that would be a real ground breaking video.
I am curious how great the difference in thickness of active material is between your two systems, and also I wonder what the upper limits are on how thick one can make the active material, and what limiting factors tend to come in to play as one thickens the active material.
+Ray Wharton shame about the delay mate - but good luck with the farm. I was thinking about a bike myself - i might buy one to do just exactly that with lol - I should measure it but it was just a how to make it demo. The limiting factors would be resistance mate - the thicker it gets the greater the distance to the collector plate and the higher the resistance. Attachment will be a factor too and electrolyte penetration
+Robert Murray-Smith lol. I was sitting here pondering the transient punch through V, Q and resistance issues as I saw this post. Downloaded Grafoil engineering guide and thought, quite an engineering trade-space. Permutations offers much room for optimization and plenty of interesting lab work. Amazing what 50 years of quality lab work can yield for things like grafoil.
+BluesDoctor i tend to recalander the foil down to a few microns via a two roll mill - it is amazing stuff and you are quite right there is a ton of work that can be done here
Thank you very much for sharing these information with us . I have several questions. Hope you don't mind!
1.If I connect several hundred of these "SuperCapacitor" in parallel can I draw lets say 100 amps without any dangerous or burn these plates ? And If the answer is yes
2. how can I calculate the duration which these Capacitors can deliver 100 amps (using this formula ---- Ah = F * V / 3600----) or something else ?
3.How much the ESR or (the peak current )?
4.my final question is If I increase the surface area size of these plates the capacitance will increase but the voltage rate will decrease right ?
Thank you very much :)
+Abdulla Qasem no worries
1 - yes
2 - looks good
3 - don't know
4 - capacitance increases voltage remains roughly the same
Why voltage need to be that low? Any chance to build super capacitor that hold 100V for example?
because small ones are quick to experiment with - i have built big ones in other videos
Can you reply with the link about the 60kF cap you cobbled together?
I just want to thank you for this video! Been wanting to experiment with making a super capacitor power storage system
+Kevin Hughes (netsplit) cheers mate - good luck with it and keep me in touch with how it goes
Do you think I should make a science fair with this? I would really enjoy the input!
Can you build me a flux capacitor?
lol - nope
This video was the spark which ignited a raging fire. (Not literally) I have watched it and shown it to so many friends. My obsession with building supercapacitors marked the start of a very wonderfully strange chapter in my life. the one thing that I was inspired to try was to use “neverwet.” As a separator on carbon fiber veil that has been lightly electroplated with either Au, Cu, Ni or Ag. using sodium silicate as both a binder, and electrolyte; when mixed with a very small amount of grapheme oxide and acetone and doing what could be interpreted as a supercritical drying process, by freezing it, and subsequently baking it @ 250-450f in a (homemade) autoclave under the highest vacuum I could generate with a couple of reversed air compressors and a refrigerator pump , the whole thing puffs up like breakfast cereal, and hardens. Technically; I believe it falls under the definition of solid state but I don’t have any collegiate education, so its highly likely I’m wrong about that…(I later realized I had made a kind of grapheme/silica aerogel) it was solid state but in regular atmospheric conditions(I live on the rainy side of the big island of Hawaii) it would melt after a few days. I also tried this as a bastard version of the “crystal battery” which has been used in the RUclips community by many, for a long time. This tiny device seemed to charge itself. Unfortunately the majority of my toiling was destroyed in the 2018 LERZ eruption which ate half of my neighborhood, and proceeded to melt a few more including the town of Kapoho, the largest eruption in the recorded history of Hawaiian islands. It also added an additional 18 acres or so to the island after filling in Kapoho bay. The lava was extremely liquid, and at one point it measured almost 4000 degrees Fahrenheit. I have been working as a guide in the ocean and on land for a dozen or so years taking tourists to get on top of and adjacent to active lava-ocean entries. I have never measured lava more than about 2700f. My point is that there’s an awful lot of elements that came to the surface in my neighborhood and have been oxidizing in different layers for the past 4 years. The lava was 120ft thick in some places(will be cooling off for the next 20 years or more)but it is porous and has seawater leaching into it. I’m wondering if the flow fields may possibly be able to hold a charge…there’s a geothermal power plant that just so happens to be surrounded by the new lava… I find it very intriguing. I have 2 children who are 3 and 5; I rarely get the opportunity to talk to anyone who has the slightest idea what I am trying to say…what do you think?
Hi there! Wonderful video...
So tell me, how would you build a series of Capacitors that can be connected together to have between 48v and 55v that can be used as a storage battery for solar applications?
Would you use this same method?
I need a a bank that is about 30kw +
Any guidance?
Hi Rob i couldn't quite get the jist of the activated carbon / acetone mix, can you please tell me what the binder was.
kev
just experiment with it mate - PVA works well but so does SBR and CMC
Robert Murray-Smith many thanks Rob, did you check out that web site that i emailed to you yesterday ?
i did mate and sent a reply about it
Also as for the layer that holds the electrolyte... The tissue, if holding more electrolyte yields more current and voltage potential then you shoukd look into magnesium carbonate... Gym chalk... I saw an experiment where a compressed block of this stuff was placed inside a container with 8 times the volume of water and weighted down until nearly all the water was absorbed by the block... Now when they removed the block it hadnt swollen in size or become soft... And when they broke inside the block all that water was contained in just a few mm at the bottom of the block... Surely electrolytes can be contained in such a medium
Great...marvellous video, Mr. Murry-Smith!
Love and peace to you and your beloved.
15:21 sound of silent satisfaction
nothing wrong with a bit of smugness every now and then mate lol
One of the things I think about with graphene is purity, or just making sure what you have IS (the right type) Graphene and not just activated carbon, like you said (Especially By The Ton)
By Contrast, is the quality of nanotubes easier to come by? (Whether grown on a substrate, or pulled from a forrest
Robert, do you think making the activated charcoalfrom hard wood charcoal CaCl would work OK? Thanks for the videos.
+Bill Henry well worth a try mate
+Robert Murray-Smith and would one still need to exfoliate that "charcoal/activated graphite" and then hydrothermally process that exfoliated "charcoal to activated carbon" to get GRAPHENE ( or the acetone/h20 combo to reduce to GRAPHENE) or am I still missing or adding a step to the gentlemen's above (charcoal to graphite to GRAPHENE ) process? Thank you and apologies for any redundancy in the query, And SUOER thanks for this share, big big ups Mr. Smith!
+ROMAN GABRIEL I think he just wants to make chatcoal and grind it up mate. If you wanted to graphetise the charcoal you would need to hydrothermally carbonise it with a nickel or iron catalyst then grind it up - without a doubt any processing of the carbon that increases surface area or functionality will lead to a better capacitor - but that is where the experimentation comes in
Hi, I seriously need help!
Mabye anyone who did something with Supercaps can help. I have been working on Supercapacitors for 6 weeks now, with no sucess. I made Supercaps with aluminium Foil sheets coated with activated carbon, Kitchen Tissue Paper as the Separator and Sodium Sulfate solution as the Electrolyte. Problem: the "Supercap" had a Capacity of less than 1mF and discharged itself from 1.5V to 0.2 V in a few seconds, without a load connected!!! What did I do wrong?? I need Help very soon, so pls don't hesitate to help, even if you have only a little hint. And be aware, my English is bot very well. Thanks a lot !!! 🙃 🙃
Initially congratulation for your video and your humour.
Thus to obtain a super electrolytique capacitor one takes a graphite sheet one applies graphite oxide diluted in acetone above, one applies an insulator example a paper paper towel over the oxide coating graphite dried and then one pours some drop of adhesive contact above the insulator and then one gives an oxide graphite sheet impressed of graphite and that it ?
Which proportion of acetone mixes you one with graphite oxide?
Thank You :)
I remember watching an older video on capacitors and capacitance and them saying it would take a capacitor the size of a skyscraper to hold 1 farrad, that been said i think that was for oldschool capacitor design
Damb it can't even see your close up of what you are making my friend . 😠 Whats the use? I GET IT BY THE WORD CALLED GUIDANCE AND I SEE YOUR DIRECTING US AWAY FROM AS YOUR DIRECTING US AWAY FROM THE SEEMINGLY MORE POWERFUL BUT LESSER OF THE TWO, NOT HAPPY ABOUT THAT PLUS YOU NEED A NEW CAMERA MAN HE SUCKS OLD CHAP. BUT THANKS ANYWAY. CHEERS
Wonderful! My guppies are doomed...
lol
Sir . Why didn't use in electric cars ? Instead of batteries? What's problem?
how many seconds did they run for at 1.2v .04ma? is 1F 1W for 1s? if the 1F discharged more than 4x faster than the 4F one than graphine is better. btw 1m2 of (assuming) 4Ws capacity is equal to one 4.2V 3000mah 18650 battery. so the question is: how many cm3 can you fit that in and how much will it cost to do! if the answer is under $20 and less than 36 (1.8*6.5*pi) then you should be giving panasonic a call!
I love watching your videos, very interesting and informative, may I recommend a microphone on your coller or something closer to your mouth, your shop creates an enormous amount of echo which makes it very hard to follow what your saying. Keep up the excellent videos, thank you 😊
and I'm over here trying to understand😱
lol
Awesome - thx so much. Why bother with rechargeable batteries when we could use capacitirs? Anyone?
Been trying to do the same with graphene and aluminium foil and carbon cloth, with a paper towel separator dipped in electrolyte (tried KOH, Na2SO4, and H2SO4). Always ends up discharging through itself even though there isn’t any direct connection between the electrodes. Dunno where it’s going wrong? Some help would be much appreciated. Cheers!
I have a question, Can this type of SuperCapacitor work through a heating element? (let's say I stack 100, or 1000, of them together).... can they run a heating element for a few minutes (after being charged of course), since the load has a lot of resistance? Thanks
When I saw the 2.7 V and 500 F capacitor open I thought you were referring to how it was built, but I was wrong.
Through your explanations you drew my attention, but because you do not show clear images with details about the realization of the capacitor
you bored me quickly.
You managed to complicate things so that I was disinterested in this video that seemed interesting.
You probably made this movie to find out how not to make a supercapacitor.
A video in which the director is in the foreground like Brad Pit, is a failure from the start because Brad Pit cannot be imitated.
In the foreground must be the achievement he is talking about.
An uninteresting movie.
.......looks like zinc is real zinc in Britain. In Australia zinc sheet would be steel sheet plated with zinc alume. If it's plated with actual zinc element then it's called gal sheet . Not sure pure zinc sheet for roofing is marketed.
I am saving up now, so I can buy one of the kits from your shop!!
And I am going to have Sooo much Fun!!
I hope to be off grid within this year!! 🙂. XxX.
What is the binder used that's dissolved in acetone? I'm not finding the video
8:32 activated carbon, in this case carbon for a fish tank filter
He didn't say.. But loads of plastics dissolve in acetone. Styrofoam for one, as a cheap option.. Also cellulose dissolves in acetone.. however you might want to look at the electron mobility of a binder/active material combination to better determine a binder profile.
In India there are some sellers that scams people. I purchased sodium sulfate and tried to make a supercapacitor and it didn't work at all. I thought I was making some mistake and was hopeless. But after testing the conductivity of the electrolyte I found that it was something else. So I broke a old cell phone battery , cleaned the copper foils and made a super-capacitor with (NaCl) salt water as electrolyte and to my surprise it works quite well. If you don't have any ingredients near you, you can try this out. But it is far from perfect ......
Hai sir,
Can you please explain about the electrolyte and its concentration ??
Hi Rob. At the end of this video you guestimated that this would be about 500F per gram. How does this compare to your latest iteration that's 3wh/kg. I've tried finding out what equations to use to convert and compare the measurements but I still don't understand how to do that properly.
Has Elon Musk experimented with graphene super capacitors?
Hi Mate...
After running the motor until it stops, hook the battery up to your joule thief...I've done this with my batteries and it has power left after running the motor to run the thief for quite some time.....
First off I want to say thank you for these videos. So I’ve followed your channel since your video on making a solar cell from extracted leaf chlorophyll. I’ve had hopes of someday building my own generator one day for years now. Something of which I know very little about, so I’m constantly looking for answers. I’m constantly finding myself back here with a great deal of the answers I’m looking for. But the one I’m having troubles answering is whether or not these supercaps are a suitable alternative for energy storage for off grid use. I’m reading and seeing a lot of back and fourth on this. Would love to hear your thoughts on this if you wouldn’t mind.
by accident, i put activated charcoal in my microwave and it sparks! i was using fluval carbon, external filter material.
Love the content, the only critique is camera quality, not only is it too far from where you are working but too blurry, we really can't see what you're doing w your hands or how you set the thing down. When I was testing it seemed that if I set my supercap test on a table it lost the voltage on the table, are you setting it on a metal table, or is that glass, can't see? I find it a bitch keeping volt tester, charger on a messy assembly and wonder how the hell you do it w.o pulling your hair out, and the audio quality sucks pretty bad too, I've got top notch audio system and using my best headphones but not picking up all the words, you talk fast like me
I would like to know which binder did you used and the percentage in relation with the activated carbon.
there are a whole range if you watch other videos i talk about binders but PU, PTFA, SBR, CMC, PVA are some good ones and around 5-10% by weight works well
Four Farads is a crazy amount with only 2 plates and a few grams of materials! Mind blown!
I knew you were an excellent teacher the moment you said the current combinations are probably not the best so experiment.. subbed!!❤️😊
What is it that you can think of that you know or don't know about zpe zero point energy
Be warned that the power supply people may not want you to let the cat out of the bag
Ha ha old. Love your show
One of the best science shows
You must be a scientific teacher
Great Lecture I liked every step I am keen to know the capacitance of the grapheme supercapacitor.
Did I miss something? Graphene is just carbon, so isn't graphene oxide is Co2 or CO?
Please tell us about the properties of different electrolytes. acidic, alkaline, salt, neutral, which feature of their work, in super capacitors. and is it possible to use an electrolyte designed for electrolytic capacitors?
18:05 Makes sense the Activated Charcoal would store more. It has a larger surface area cuz of all the porous holes in it.
I watch all your video and they are great . Can we work on a higher voltage supercapacitor?
We live in an AC world and that's where the scientific challenge is finding a dielectric that can store high energy yet can withstand ac voltage.
I have a idea to make a new type of lithium ion battery it has a semiconductor sandwiched plate in the center of the cell it regulates the charge and the discharge of the cell. This prolongs Battery life by regulating charge and discharge cycles and it stops Dendrites from forming shorting out the plates. The battery has 4 connections +and - and emitter and collector these connections control the passage of electricity taking the place of the separator in the cell. The battery is a rolled up cell design.
Did you say 500Farad capacitor??? What should you have said??
Wow, that was awesome! I am an engineer rather than a scientist. Thanks for the explanation -- very interesting. If the capacitor was pressed properly in a production environment, how much capacitance would result? Thank you. I'm looking forward to the next in the series. I do have one question though, I don't understand what is a symmetric capacitor vs non-symetric. Is it what I might call a polalrized vs non-polarized capacitor?
+Inspironator i have made the 1 cm square graphene one at 9 farads with three dips and compression. Symmetric is just where the same active material is used on both sides - initially it has no polarity - after the first charge discharge cycle it gains polarity - asymmetric is where two different active materials are used - this has polarity but it depends on the material used
Top notch tutorial, Appreciate your time and effort, sir
That's pretty amazing
It would be interesting to know the self discharge and esr parameters.
for the sound fix download Audio Mi- volume booster & equalizer tool from chrome store and press mono button ,youre welcome
That's a pretty nifty little device for measuring capacitance but I think it's kind of silly that it set up to make you hold the button in the entire time it seems like a hell of a shortcoming in design
4 Farads on that device? Ok, Officially mind blown. Not long ago I was doing a Fire Investigation and we found hundreds of Capacitors in a Arsonists storage shed. The PhD that helped us on our case said a 1 Farad Cap would be as big as a room. Either I got the dumbest Engineer or I misunderstood what he was telling me.
a farad used to be huge when stored on a cap mate but that started to change around 20 years ago now you can store a farad on around 12 square centimetres of active material - but you are right 4 farads on that little thing is mind blowing lol
I was hoping to get in touch with you over an idea that would have medical benefit.
Can I make and experiment/research something made of metal wool?
can you take ash from a camp fire eat it up to burn of the rest that is not bracken down to carbon and press it together until you have a sheet of carbon
Incredibly inspiring, i am so happy for finding your channel.
Nice video. What would be the best electrolyte to use with aluminium sheet and how I determinate what voltage can I charge my capacitor once is ready ? Anyone ? Thank You
A very good learning and knowledge gaining vedio for learners
If you angle electric container of energy to funnel the pathways
From the title I expected something simpler but it is very informative
I think you have a fantastic ethos regarding try it yourself, change the recipe etc. That is the way I have always learnt, often more with failures, but persistence is the key to success. Keep up the good work, you will make that million.
+Martin Counsell lol - cheers mate - what is it Edison said 1% inspiration 99% perspiration lol
Russian Doll cascade would discharge in a resistve way
Why does it seem to release its energy more like a battery than a capacitor?
Absolutely amazing that such a high capacitance can be produced so simply and cheaply!
i think so too
What is the instrument that u r using to calculate high capacitance ?
I love all your videos, very informative and extremely easy to understand. You make a great teacher. Unfortunately I can hear what you're saying in this video and I'm excited to learn about this. Can you please add subtitles?
Please disregard, it was my phone acting up
this video is super blurd..
At 4 Farad and 2 mg of material, you would be looking at around 2000 F/g; much higher than your off-the-cuff calculations of 500 - 700 F/g you call out in the video. That just about beats the field far as I can tell.
I did read somewhere that a nickel hydroxide electrode was producing +3000 F/g but given your environment, set-up and simple chemistry, that's downright impressive.
all the info is on the vid for folks to make and verify if they wish mate - there is going to be a difference on specific energy when the final device is put together
LOL, been watching old videos. I have this standard ~7.5"*9.5" composition book with 100 sheets on it. I calculated ~18A per sheet pair so ~200A per book. A stack of 4-8 books could start a truck. That's between 1/8 to 1/4 of the normal battery size. And this is with just a standard "everyone knows" recipe using kitchen towels.. LOL.
Ofcourse it would take quite a bit of sheets to match energy storages. I'm thinking, big cheap diy solar storage. And above all, safe.
No audio, ):
does anyone else has same issue too ?
Or roll type better then square plated design
sir u are so inspiring........I am your fan.....I remember reading somewhere that voltage in a charged capacitor falls exponentially with time....what is chemical part of a capacitor/battery which is responsible for volts? and what part of it is responsible for amps?
reaction kinetics give volts and amount of material give amps - well bascially
