    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!

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!

    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?

    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.

      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.

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!

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 🙏🏻

Don't know if there is any graphene there but there was remarkable increase in conductivity compared to the dry graphite powder. Kindly, cast some light on what must have happened. Thanks and regards.

      Like super capacitors ... they can charge fast ... but the thing is that they can with hold that like battery...

    I love this video. When I was working with electronics in the 80's, if we needed a capacitor even close to one fared, we would use an amplifier circuit to simulate it because such a large value capacitor was a practical impossibility. Now you can slap one together as easily as any Mod Podge craft project.

    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.

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.

    If the long capacitor electrodes are impregnated with an electrolyte, the capacity increase. In some cases, is impregnated under vacuum 24-48 hours. But even without vacuum markedly significant increase in capacity. Thank you for your Vidoje they sparked my interest and now I find it difficult to stay :)

  • @robertzitting4547

    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 😊

  • @yougeo

    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!

    • @ThinkingandTinkering

  • @flomojo2u
    @flomojo2u 8 ปีที่แล้ว

    Hi, very interesting work, I have watched some of your other videos beforehand but this one was a little tough to follow partly because we didn't get a close up view of the entire process; as it was we had to more or less imagine what was going on several feet away, at the table. It was also a little tough to tell what was going on because you listed so many possibilities for experimentation without spending some time explaining why you chose the ingredients used in the video. I understand that we are being encouraged to try things on our own, yet as another person commented it would so helpful to have the complete process documented (Maybe in the video description?) so we have a baseline to compare and try variations on with a known-working model. It doesn't need to be the best or even fairly good, just something to start with. Keep up the great work!

    • @ThinkingandTinkering
      @ThinkingandTinkering  8 ปีที่แล้ว +2

      +flomojo2u Hiya mate - i am glad you like the video - I don't really believe in hand holding too much - there has to be work, effort and failure on your side - that's how you learn

    • @flomojo2u
      @flomojo2u 8 ปีที่แล้ว

      +Robert Murray-Smith I don't really see it as hand holding at all, this is how scientific research is done. You've made some very impressive claims about the capacity and nature of the super caps you've produced, but to allow anyone -scientific researcher or just a hobbyist- to validate your claims it's necessary to detail the exact steps taken. The more ground-breaking and revolutionary the claim, the more the need to validate it. I understand you're encouraging experimentation, however it may discourage some people to be unable to start from a known-good point where they have at least some small hope of it working. It's not always necessary to re-invent the wheel before improving it.

    • @yougeo
      @yougeo 8 ปีที่แล้ว +2

      I want to say i liked that you explained the different possible effects of all the different possible materials. It made it more clear what was going on with he process not less as this commenter seems to think. Larfe surface area bound but not insulated by the minimum needed adhesive making contact with the conducting plates best suited for your chosen electrolyte. Simple!

    • @flomojo2u
      @flomojo2u 8 ปีที่แล้ว

      +yougeo Well I'm glad someone found it simple ;). Part of my objection to the lists of all the potential materials/electrolytes/binders is that Robert went on to list so many without actually saying what sort of reasons you might want to use a particular electrolyte, for example. I get that you don't want to use light metals with a strong base/acid as this would dissolve the electrode/plate, that's quite clear. I just would have appreciated reasons that you *would* want to use various materials together, maybe some of the experiences he's had that would be both interesting and informative. And as I've mentioned before a simple statement at the video of what we'll be seeing today (I.e. "Today we'll be comparing XX and XX, using XX and XX Here's why...").

    • @ThinkingandTinkering
      @ThinkingandTinkering  8 ปีที่แล้ว +1

      +flomojo2u This video isn't about making claims mate - it's about encouraging people to experiment - if you feel it discourages you - well - no problem - you can't make everyone happy. From the feedback I get a lot of people are encouraged to try and as far as I am concerned the objective is achieved

  • @brunomarier8872
    @brunomarier8872 6 ปีที่แล้ว +1

    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 :)

    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.

    • @ThinkingandTinkering

      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

  • @dytiscus
    @dytiscus 6 ปีที่แล้ว

    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

  • @aomanchutube
    @aomanchutube 5 ปีที่แล้ว

    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.

    • @aomanchutube

    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 :)

  • @flash001USA
    @flash001USA 10 หลายเดือนก่อน

    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...

    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 ......

    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.

    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?

    • @ThinkingandTinkering
      @ThinkingandTinkering  8 ปีที่แล้ว +5

      +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
