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 😂😂
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!
It's good to watch these old videos from 2016. Full of great info :)
When he announced "4 farads" it genuinely made me smile. The future looks bright.
awesome mate lol
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.
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.
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!
RMS, you're truly one of the greatest of all time.
-joshua bertrand
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
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.
Thank you for sharing your knowledge.
+John Allen cheers mate
I love your videos and how you share your knowledge with others. To those who criticize you in any way are nothing but complainers, not contributors.
Your channel is giving me flashbacks to the days when BBC used to actually be educational. Thought provoking content that encourages us to explore the perpetually uncharted world of tinkering in our own garages and kitchens? We haven't had that spirit here since 1969! lol. Hats off to you sir and thank you for the inspiration. I really appreciate your enthusiasm in your presentations. It's contagious
Hello Robert, I just wanted to say I have been putting off opening a google anything, BUT I did cause I APPRECIATE all the effort and commonsense you are able to impart to anyone willing to get their hands dirty. SO>>>> Thank you for your time and efforts. GREAT job
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.
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 TH-cam 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?
"kitchen paper, because it's easy to get hold of" good times, good times.
Bbbbbb
Thank you Robert, not for only answering my question of "how to" cleanly and clearly, but inspiring me to experiment and find tomorrows technological break-throughs thanks again great as always keep it up!
awesome mate - I am glad you found it useful - cheers
I knew you were an excellent teacher the moment you said the current combinations are probably not the best so experiment.. subbed!!❤️😊
I so love watching your videos. I was interested in science as a child and was learning from a teacher that reminds me of yourself. Having someone with such a infectious attitude of teaching is grand. I was transferred during my middle school years but never found a science teacher such as yourself that was so knowledgeable of his teaching as much as you. I find it is never too late to learn. Thank you so much for your videos. From across the pond Hello and have a great day.
hiya mate - thanks for taking the time to write and say that - awesome my friend - cheers
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
Hey Rob, I have started watching your videos very recently, just want to say a massive thanks you are a brilliant mind and a wonderful inspiration!
cheers mate and thanks for taking the time to post
Incredibly inspiring, i am so happy for finding your channel.
Hello, you are doing a very interesting job, but more valuable is that you share the fire of the heart. Good luck with your endeavors and good health to you!
So touching to listen to your enjoyment upon pondering the measurements. thank you for your consideration to teach. the video was crystal clear and well done With tons of highly informative research. This is undoubtedly the best technical video I have seen in the last number of years. This was recommended and I couldn't have imagined the value. So it was quite encouraging. Funny I was searching around asking about measuring large capacitance meters and was told they did not exist. Glad that was wrong! Cheers!
thank you for taking the time to post and say so mate - cheers
Four Farads is a crazy amount with only 2 plates and a few grams of materials! Mind blown!
VERY encouraged here to experiment now! Thank you dearly for your dedication and open source attitude!
+PartisanGuerrilla and let me know how the experimenting goes
Great...marvellous video, Mr. Murry-Smith!
Love and peace to you and your beloved.
Absolutely amazing that such a high capacitance can be produced so simply and cheaply!
i think so too
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.
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
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
Top notch tutorial, Appreciate your time and effort, sir
That's pretty amazing
One of the great informative video I have ever watched, thanks a lot sir for showing the capacitance ,
Apriciate you a lot
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.
One of the best video's I have seen on You Tube, well done. I think that these devices will be the future of everything electronic. In admiration, an elderly, retired electronics engineer weened on vacuum tubes....;-)
awesome mate - cheers
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
Great vid Rob, full of step by step information as well as many tantalising ideas hinted at.
I really must make the effort to replicate your experiment and hopefully come up with ideas along the way.
All the best - Martin.
+solarhope - you discover by doing mate
That is outstanding!!! I'm going to make some of these and see how they charge with my Bedini-starship coil energizer. This is really useful information, and a must try. Thanks for this amazing video
I would go back to school to take courses from you Robert. This video was great. I love learning from you!
cheers mate
Yup... it's pretty damn impressive. Congrats man and
thanks for sharing. Regards from Argentina!
Wow!! 4 farads in 1Sqcm!!! Discovery of your channel has been the best thing that has happened to me in the last couple of weeks. It has rekindled my childhood interest in doing science experiments. The first thing I am trying to replicate is your NASA Stirling engine but with 2 Pringles potato chip cans…not successful still as I think the rubber balloons as membranes are too hard for it, or maybe using hot water cop to heat is just not enough to make it work. Will keep trying and if successful will post here. Thanks for all the fantastic work you do 🙏🏻
Thank you for this I have been looking into building these and have been looking for a good place to learn I think I found that place!
totally awesome and inspiring videos!!! keep em coming!! love your tutorials....keep up the great work!!
+Scott S cheers mate
Thank you man, learned and enjoyed a lot
I have watched this 3 times now and it still excites me 👍🏻
Thats 4 times now 😂
This is a great video glad i found it. Thanks for the detailed explanation.
i am glad you enjoyed it and thanks for taking the time to post - cheers
Never stop, Sir!
+Neil Smith cheers mate
Bravo. Well done and great work stimulating both the young and the old. Experiments do not have to be hard nor exceptionally complex, just well thought out. Hint, use the noodle...
+BluesDoctor cheers mate - and absolutley
I love the cackle hehe that is impreasive capacitance for such a small package.
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.
I really enjoyed your video. Thank you!
thank you mate and thank you for taking the time to post
Amazing.... Good work!
-Nils
From the title I expected something simpler but it is very informative
A very good learning and knowledge gaining vedio for learners
Great video. You are a legend !
Before I was intimidated to make a simple electrolytic capacitors for my electronics 101 class now after watching your videos it looks like I’ll actually make a great super capacitor has one of my class projects thank you for bringing it down to a simple level that’s not intimidating easy to understand. As easy as making a penny and nickel lemon battery 👍
Thanks So Much for Sharing!!! my you live long and prosper!! i will attempt to build a few for sure i have all the stuff now, again thanks so much
awesome mate - good luck with it
That is very impressive
Thanks a lot for your super informative videos!.
I have tried to make them but end up eroding the Aluminium Current collector after a while.
Any suggestions?
Great Lecture I liked every step I am keen to know the capacitance of the grapheme supercapacitor.
awesome video bro... keep up the good work!
I love you so much. You are an inspiration....
+DrSpooglemon bless your heart mate and cheers
thanks for sharing all your know how. I don't think the wives and mothers like it much though. I can never stop watching.
lol - awesome mate - cheers
Like the modern day Professor Laithwaite. Thanks very much.
lol - cheers mate
great video gonna make some tonight
Brilliant, thank you.
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.
Very nice summary to tie things together. Thank you! Experimenting with various sifted carbon grain sizes with various adhesive glue viscosities looks promising. Perhaps even a compressable spongy adhesive to make a variable supercapacitor!
+yougeo i did a video on exactly that mate lol - let me know when you do a video of your experiments i would love to see
thanks
your videos are really inspiring :))
by the way what's the best capacity per weight that we can get from these materials?
if 500 farad per gram so why we don't have commercial ones rated at this? I'm wondering what's the limitations?
Super happy about super capacitance
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 :)
Nice work indeed, can you advise on making tank caps for a bench top induction furnace? Cheers
Great video really enjoyed it. A young student of mine is trying to build a super-capacitor for his school science fair project. Our first attempt using materials to hand and we didn't have too much to use (two one square inch pieces of Al sanded, dipped in very finely powderized activated charcoal suspended in a corn starch solution and lightly baked in a toaster oven, and separated with one sheet of toilet paper soaked in saturated MgSO4 ran a small electric motor (designed to run off a few square inches of solar panel) for about 3-5 seconds. While I was very pleased with that result. Our biggest problem seemed to be leakage as it bled down quite rapidly under no load. Any tips to reduce leakage. Thanks Phil
Your the best. Thanks!
That shows that carbon must have huge surface area.Very good demos thank you.
cheers mate
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
That was a crazy demo Robert! Enjoyed it alot;) Think I might take up the challenge and do experiments on my own. Cheers :D
+noilex go for it mate - and let me know how you get on - there is a whole load of things to discover out there !!
Subscribed. Great video, thanks.
Very thorough explanation. Thank you. Just one small detail I would like to mention. The mike picked up a lot of noise form the foils. Something to keep in mind for future videos. Thanks...
Hello sir
First of all I would like to thank you for making this good video.
I want to ask you for cv measurement EC software is there do you know ho to use for measure the cv nd cd.
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
Wonderful! Thank you!
glad you found it useful mate
nice video , really informative !
+сталкер чворович cheers mate
Awesome video
Really astonishing on table top without any messier a 4 farad grate... on the face of others who make it so delicate and something that can be manufactured in pricey labs...
just think of all those greats who did wonderful work without pricey labs - exploration of ideas doesn't need a great deal of money
Very well said .... I belong to India from a ruler back ground ... I was fortunate that I got chance to study and become capable to earn bred ... but when I go back I created people and villages having less electronic... still they just have 4 hr in full day ... I always think of doing things that could benefit them ... so I keep on reading and understanding things that can help them ..
Like super capacitors ... they can charge fast ... but the thing is that they can with hold that like battery... I constantly look beat of both worlds... they can charge fast .... with stand the charge like battery ... cheap so that all people can afford and can solve there real life problems ....
i always try to make things that can be produced any where in the world with a minimum of machinery - if any at all!
I really enjoyed watching this video and it helped me a lot to understand how the preparation of the super-capacitors is done
I am currently in the course of a project to manufacture a supercapacitor and I have a question if you stay working on the supercapacitor
will have I the opportunity to spend an end-of-study internship in your laboratory
How does this only have 125k views......
TH-cam CEO is a SJW-Femminist
SJWs dont like useful videos ;D
Great! I'll try it...
Thank you :)
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
Dear-Mr.Smith....Good Luck in..2017...and YES.hello from Latvia.
cheers mate - have a good one too
Thanks Mr. Murray... Brasil ( Guarapari ES)
cheers mate
I love you, man.
fantastic - clear explanation and fun - yes experiment the components are there so why not... how exciting - really this just opens up a whole new world... thankyou
cheers mate
nice one bought your e-books too, Graphene and supercapacitors - a good excuse to build a kiln in the backyard methinks... love messing with fire bricks and acids... Are you still making the ink for sale?
no mate - but i did a couple of videos on how to make it for yourself
awesome yes I have watched - very inspired by your work and knew I would just have to try something from your vast pool of info... I'm loving the graphene intercalated compound film at the moment, although handy little amounts of aluminium chloride have proven hard to come by in Australia I do have a source albeit expensive - saving pennies...
you can make your own by dissolving kitchen foil in brick cleaner - aluminium in hydrochloric acid - google will help with directions
OK, I got your super-capacitor replicated and it works just as you've described, thank you...
One question if you could tell me about the commercial super-capacitor you have disassembled: what solvent did you use to remove the electrolyte? please...
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?
This is so good lest make things and explain it professionally so everyone love YOU , especially the way you talk , what a wonderful world we live , at end he make a joke of it .
cheers mate and yes it is a great world to live in
You are a science God... :-)
Good job 👏 👍
Awesome! Mate, Thank You So Much :D
no worries mate
