That's one hell of a watch battery!
LOLOLOLOL
+marthale7 Solar Panel? Inside your house? Weirdo.
***** I don't think you know this. This capacitor, does indeed charge quickly, but it also discharges quickly.
He charges at 1 amp for 10 seconds. I'm assuming you will have a tiny solar panel, so it will charge at 0.2-0.5. Your clock will use about 0.2a
Hmmmm.... Controller?
+marthale7 yes you're right, but super caps can buffer power generated by low speed wind turbines so the charge rate is correct for those batteries.
+Danyal Ahmad i dont think he is that weird, i just took a few of those small chinese garden solar panels, and measure around my house.
Yes, i'm one of those weirdos that has windows in my house. aka, sunlight during the day.
I'm confident that at least half of my rooms i could setup a indoor solar clock.
But unfortunately i live in the northern hemisphere and that results in more than 14 hours of less than ideal sunlight for solar panels, making hard to charge enough to last while its dark. Unless you use larger panels of course. ;)
I really appreciate these technology videos. I love making this stuff and these videos are so helpful!
Really great video! I was pretty excited and asked about the inverter even before it was finished. And of course, you go and plug it into an inverter. THIS is what it's about, real time tests, applied electricity, such awesome progress!! I've got my lab nearly set up and some really great graphene powder from Celtig and I'll be joining you soon on the youtubes!
i am very happy to see you are also working on this concept.i bet you will be making super caps for your quad copter very soon,chuckle.thank you so much for sharing your work.i spent 4 hours reviewing your work on the overunity forum.the earth battery was a great beginning.you have traveled very fast even as you bring us along.thanks again.
It is something that we all wait to see, step by step how to make a super capacitor. Great video man, i hope yo can make more videos about the ingredients and the construction. CONGRATS my friend. Big fan of your work.
I'd love to see a "how-to" video on how you created these super capacitors!
I have also viewed all of Robert Murray Smith's videos and have learned an lot. I'm quite glad to someone trying some of his stuff.
Thanks for the amazing video. One quick question: After that 10 second charge, for how much time can it run that fan ?
man I want to say these are some really fantastic videos. thank you for teaching me some new things.
how much energy are you storing in this thing?
Those graphene supercaps are neat. Great video!
Nice one laser sabre all good, one never knows what you will dream up next- brilliant. Have to understand how the two final pieces fit together to make the final super capacitor. Keep going mate I am a great fan of all your videos and free distribution of knowledge. How the flying around your farm, going these days, you might make it to the next county when you perfect these thin super capacitors. All credit to Dr Murray-Smith for his capacity to invent these things.
Here you can get these frypan splatter screen sieves from Stainless steel at Amazon USA that you can use as BIG electrodes:

That's Awesome lasersaber. I got Robert's Super Capacitor book also. Thanks it's great.
awesome. i am looking forward to the detailed construction tutorials. i hope all is well in your world my friend.
Awesome video! Can't wait to see it on the back of a solar panel!
Im inspired by your comment to share our progress's with this technology , this collaboration of great ideas and it's ability to maximize energy efficiency to me is what it's all about
Excellent, I look forward to what you do next...
Awesome work! keep the video updates coming!
That a beautiful thing you got there.
I've been wanting to power a 3kw motor for an hour or so. How man panels of 12" x 18" do you think it would take? It's for a small motorcycle project that I want to start and batteries are the hardest part. I wonder if I hooked up an alternator to that motor, could that charge the capacitor while in use?
Very impressive.
How long does it hold its charge if you don't connect it to anything?
Awesome stuff!
Have you done any energy density calculations yet ?
I've read Robert Murray Smith's Book, have you tried any of the other electrolytes? Specifically Poly Vinyl Alcohol made from white glue. The reason is because it wouldn't evaporate.
That's really interesting. I am impressed with these things, Are you considering some kind of mass production? That would be amazing!
Hi Laser would love to know if one of these super graphene capacitors could be scaled down to a very very small scale if so how small and how flexible could this be made. Secondly what does the carbon do for the capacitor.
Superb and thanks for the initial construction tip !
Main goal for my efforts (failed so far) is to power a small R/C plane. Can be a glider at first, motor later. But the idea is to make the slimmest lightest supercap with this high density. Equiv run time and weight to a small lipo...because, having trouble finding 40mAh or so anyway !
Hopefully you are looking at a similar avenue as a real world use ? perhaps to power an onboard camera for your quad etc :)
danke vielmals fürs teilen deiner Erfahrung und deines Wissen!
I have experimented with ground up wood charcoal and it works great. I figured why not use something readily available and free. it works.
What about using char cloth? I wonder if it has more micro structure increasing surface area.
Cant wait to see the version you start your car with.
This is sooooo cool, thanks for sharing.
Awesome! Thank you @lasersaber for pioneering these types of things, I believe super capacitors will be huge in the future, and you are very inspiring in your work, and the fact that you share it is awesome. Have you seen TinManPower's latest videos on graphene super capacitors?
Thanks for showing me all this cool stuff. I'll be waiting for your build video with baited breath. I'd love to make a chargeable stack of non-acid based batteries to run a wind powered motorcycle. I'll keep trying stuff on for size.
Thanks for replicating Robert Murray-Smith's work. I look forward to seeing your step by step videos.
Now this is just dang awesome,
I'm interested in the application and integration of graphene/carbon capacitors with solar panels. A single silicon cell is 0.55v, so would you stack 4 or 5 to run across the cap, bearing in mind the max capacitor voltage? A solar panel built on an aluminium substrate would help keep temps down and increase output. How would a MPPT controller cope with the added current capability of a typical panel. (60 PV cells, 15 caps) would it track properly and set the cells to optimum? Unfortunately I have too many ideas and projects to explore all possibilities.
So just two plates? What about using tyvek barrier? Is aluminum ok or can we use another metal or even steel sheet metal? Copper or brass foil sheet?
hi lasersaber. realy cool thanks for the video.
what do you use for separator ?
lg
gerhard
Glad to see that two of my favorite guys are now connected to each other
I hope +lasersaber gets interested in that spinning of 2 arc magnets behavior....I bet he will find it fascinating
sorry, what do you mean by "2 arc magnets"? Would u mind providing a link or smthng? I think perhaps is something useful to me. Thanks!
half or semi circle shaped magnet.
That is great. I wish next time you can tell us more about the capacity you could reach. Thank you!
You are great keep them coming!!!
Hi, nice. When it is discharged what is the resistance when measured across the + - terminals when using a ohm meter?
Do you make your own GO power, or do you buy it. I have purchased and Downloaded the linked books, very interesting. I really have learned a lot from your videos. Thanks.
a question about putting super capacitors in the back of solar panels. How are these at handling heat?
That doing great I am going to try building the newest version of super cap now with hemp
How many Farad are you seeing in your capacitors and what charge voltage are they getting?
Did you mix the carbon/graphene with just the polyurethane varnish and closed it like that, or did you also add isocyanide afterwards?
Hey, Laser, I'm new here, and am curious about this cap. Do you have an ETA on that instructional video, as I have so many questions that it could answer. Awesome work. Good luck on construction improvements, that looks pretty dang good so far.
Hi there. Thanks for the video. I have read that super caps can only do low voltages, not more than about 3.5V. Is this true and why is it. How do you get 5V?
Have you done any measurements on capacitance? And it looks like both sides of your capacitors were made the same way so does that mean it is not polarized?
how much current does this homemade Graphene super capacitor provide ?
Good Job !
Can you make a video explaining the differences between supercaps and ultracaps?
Is it just that ultracaps value amps over volts and the reverse for supercaps?
very cool mate
Wait, you made this first?
Your awesome
+Danyal Ahmad cool
+Danyal Ahmad it doesn't really matter mate - this is a superb video and very clear
+Danyal Ahmad cheers mate
I would like to replace my 12v batt in my streetrod, I need the space and want to lose the weight! I just need to start the engine, its got a 100amp alternator! Would this work for me?
Awesome work, LS ! Well done ! And as the electrolyte you only have this phosphoric Acid ? What percentage ? Did you already play with Ionic Liquids as the electrolyte ? Check out the RUclips channels from neatpete45 and cayrex2 . Many thanks. Regards, Stefan.
it's galvanic battery
Yes i want to know the capacitance, the voltage across the bulb and that fan, and the currents flowing.
how much capacitance does your capacitor have
Hey man, i love your video's, we really need more innovators like yourself but it's good to see some of the ones we've got are happy to share their ideas to progress the technology rather than stunt/delay it for financial gain. *cough* apple *cough*. I was just wondering what sort of capacitance you're getting from the larger cap? Can't wait to start building one regardless
What kind of retailers sells activated carbon and graphene?
Where do people get it from to put out on amazon or ebay?
Great start. However, rather than just plugging in random devices, how about actually measuring the energy stored in a methodical way? Just hook up a resistor and measure the voltages over time. What capacitance do you have? How much energy have you stored?
I have seen a few comments about combining these with the crystal battery. That is we're I'm going with this to. My crystal cells are powerful enough to light LEDs, but I want more. These cells sit around all day producing power. I have 4 in series, parallel for 3 volts at a constant 60 Milla amp. I would love a home made way to store the power till I need light, much brighter light.
What kind of internal resistance do your devices have? How much current can they produce?
sweet, great job
It's galvanic or just capacitor producing electricity? Acid reacts with alluminum strongly
But the acid is not ever touching the aluminum. Watch the video again 4:23. He applies polyurethane impregnated with graphene to make it conductive and protect the current collector's metal. Then he sprinkles activated carbon over that.
What is the capacitance performance when compared to a manufactured super capacitor. Does the size and density of the granules impact better efficiency found in manufactured ones? I am looking at: weight, physical size (footprint) and output.
On the smaller battery what's the average mAh? I kind of want to start fooling around with old phones by replacing the battery with capacitors
can you give us any specific numbers? capacity in watthours, percentage energy lost while charging, ect.
very cool
cold fusion is next
Sure would be nice to see some figures about the size/weight of the capacitor as well as the maximum voltage, capacity in farads, ESR, and watt-hours/joules when completing a charge/discharge cycle. These things are conspicuously absent from a lot of these supercap videos and without this info it’s rather difficult to see the point of trying if you can’t at least know how far a person has progressed, when trying to duplicate or improve on their results.
please how can i make a graphene superconductor...like yours....and is it possible to improve it's longevity?
So is the charcoal causing a resistance? And won't your polymer act as a insulator?
hey.. ure are AWESOME!
keep post em up.
Than you very much for this. Do the other smaller one update for 2020 based on improvement. I really liked it and even built my own.
I noticed that this capacitor is made of multiple segments or modules if you will. Tell me or any of these different sections we're together in series well the whole thing is in parallel or vice a versa? If you follow what I mean? is a very important question
What is the capacitance and what is the short circuit discharge current ? Looks interesting.
Good job
Ever since Captain America civil war, I enjoy when people eye-ball things much more.
I wonder about different polar electrolytes like DMSO or ethylene glycol or some other non water based polar fluid. Maybe that'd increase the operating voltage of the capacitors by eliminating the potential electrolysis once you go over 2 volts.
How is your capacitor after 4 years? Still working?
Hi, how long will it hold a charge with no load?
Wow really cool!! Specification?
Please tell me there’s a tiny fuse in one of those lead clips?
Where do you get your graphene, and what does it cost?
i built one based on your guide and R.M.S's work but @12v 1a i only get about 3.5v charge :(
What voltage/amperage did you charge the cap at?
Hello mate... I am thinking to build a giant super capacitor to store solar energy. I need your advice to build it step by step. The giant capacitor should produce 14 volt and high ampler hour. It look like a battery in simple words.
I am waiting for your reply
Hi! Will a hybrid car work better if it has these supercapacitors instead of the battery pack? Will it cost much more?
stupid unless you plan on being like the Flintstones
Good job ! :)
Oh so cool! Yeah make this world a better place. Imagine that capacitor as the power source for a radio controlled plane or device!
Have you tried a Deep Eutectic Solvent as an electrolyte? Robert Murray-Smith has an example on his channel.
The book referenced goes hand in hand with Robert Murrey-Smiths RUclips channel too ruclips.net/user/RobertMurraySmith
I can't wait for you to post a how to build video about these :)
since they're thin, I think people could build very large and tall supercapacitors and hide them in their doors, or in the ceiling, or in the back panels of their wardrobes and use them as accumulators, like the tesla powerwall; it's a goofy solution but you won't have to sacrifice any space in your house
What do you think about TEG generators? I reckon you could build a SOLN1 alternative system using them, a generator that can provide both electricity and hot water, and maybe these supercapacitors will make everything more effective
Am I right? Hope so, I don't have a scientific degree :D
Nice vid m8 !
What is the dielectric constant of the insulator between the plates of the capacitor? Do you have the capacitance of the capacitor in farads?
There is no insulator- no dielectric.
But how it possible to make without dielectric material
mayur trasadiya Exactly. It’s not a capacitor if it lacks some form of dielectric, otherwise you’re talking about an electrochemical cell like a LiPo.
It's an EDLC, otherwise known as a supercapacitor. They don't use a dialectric.
As is with all capacitors, they have a dielectric constant, air, ceramic, mica, oil paper, ect. Even aluminum electrolitic capacitors store energy in the charge distribution of an electrolyte and the orientation of aluminum oxide insulating surface.
At the risk of overly simplifying things, dielectrics with a relative dielectric constant greater than 1 store energy inside the dielectric often by changing the orientation or charge distribution of molecules or distrirbution of charged ions. Electrolitic double layer super capacitors use an electrolyte to allow ions to get close to their opposite charged plates. As long as the electrochemical break down voltage isn't exceeded, there is no chemical change or electon transfer. Super capacitors really benefit by the huge effective surface area and how close the ions can get to such a huge effective area. Though you may be looking at two 100 cm sq of current collecting plates, the effective surface area accessible to ions is football fields immense.
if you know the actual effective plate area can you work back to determining the dielectric constant. But effective plate area is a slippery figure to pin down that will change depending on micro structures sizes distribution, powdered vs granuals, and if pressure crushes the structures. I'd guess the theoretical dielectric constants are published in some scientific papers but they arnt that important here, and if i were to guess, its probably close to 1, reflecting the dielectric constant of space between ions and their plates. Or it may be a few tens large because of ion redistribution. Consider Salt, aka sodium chloride, when placed in water does not change chemically but separates into sodium and chlorine ions. Sodium ions attract and push on different parts of a water molecule orentating one side of water molecules. Chlorine attracts and pushes on the reverse sides. The result is the ion water structure distributes the ion's charge to the outside of the water ion structure. While water has a high dialectic constant salt lowers it.
You can make supercapacitors painting graphite on paper and rolling it it up closed with an alectrode on both ends. ther eis a vidoe on it I'll look it up for you.
Robert is a great dude. he will reply to anyone. he's on facebook too.
Hi, is it a redox reaction?
the idea of superconductor on solar panels is an awesome idea! add that to the tesla home batteries and thats a wrap... they even have clear solar for windows now. Do that with a hempcrete home and you have the most green home you could ever imagine!
Greeeen
Where has robert gone? I miss his videos. How many Joules would you guess your big cap holds?
@lasersaber what is the maximum applied voltage
