Heh I clicked on this mostly to see how you'd handle the ambiguity at the edges. You went straight for the jugular on that issue. This is getting to the fundamentals of knowledge in a way that I wish more people would spend some time thinking critically about. Excellent instructional material.

[@luisca92]

Have you looked into the work of Viktor Schauberger and/or Eric Dollard?

[@luisca92]

I think your answer was very satisfying. It's exactly what I needed to hear because the way I go about engineering is very unorthodox and a lot of times I struggle with the stablished set boundaries because I see it as you do I that things mostly differ in their qualitative properties

[@igloobearred]

Agreed

[@12thsonofisrael]

@Gigs I agree, he is an excellent instructor.

[@clivebarrell6448]

Can you imagine for a moment, the number of other KZbin videos one would need to sit through to piece together this much explanation. And it's all delivered here with such eloquence.

[@Alienami]

Which is why I love things like KZbin and Wikipedia for learning rapidly, and finding novel aspects that don't get mentioned much, which is often what I base my inventions on.

I work in electronics and without a shadow of a doubt that's one of the best explanations of caps, super caps and batts I've ever heard. I really like the analogy with the balloon and the material it's made from... I might be nicking that as it's so accurate to explain caps from super caps in a nice simple manner people understand thank you 👍.

[@surfingcuriositywaves4046]

The first three minutes of this video are a wonderfully concise presentation of a way of thinking that all of us can benefit from. As a teacher of economics, I greatly appreciate the promotion of thinking aids and understanding the limits of them (as you say, when it becomes error). Well done, and thank you for the delightful presentations.

[@tevya017]

As a retired 76 year old engineer I thought I had a reasonable grasp of electronics but Robert has opened up my view of different ways of looking at things and how much there is to discover. Thanks

[@stevemileman5635]

Absolutely brilliant. Of interest to anyone, but specifically those not necessarily interested in energy storage problems. I rate Robert as one of the best speakers (and experts) I have listened to this year. He knows his subject. But that is not enough to keep him going. What does it all mean? Thanks, Rob. I want to add this, merely as an observation having watched many such videos, Rob explains something so fundamental that I am embarrassed for the other KZbinrs who even attempt the subject. That is, to my mind, the gap, being inversely proportional to the capacitance, ceases to be of significance in the definition of what it is but becomes decisive as a definition of what it can no longer do.

[@AndreaDingbatt]

Thank you, I appreciate your explanation, and understand it! I have spent a lot of time working with animals, horses in particular. And an analogy, I used to be a little confused by one person who looked down on heavy horses, but they'd be throwing daft money at a thoroughbred... I obviously learned very quickly, and I would never try to plough a field, or pull heavy equipment, with a thoroughbred.... Likewise, I'd not enter a race, on a Clydsdale.... One has an explosive energy release, but that's it. Whereas, the 2nd has great power, but its discharged at a slower pace. Now, before I disappear down a certain rabbit - hole... What I'm trying to say is Thank You!! You are so good at explaining these things, even I am regaining my grasp on them!! I was an apprentice aircraft engineer, with the WRAF, (showing my age, Lol!) But, returned home, to look after my mother, I was Lucky enough to learn about Ham-Radio, from my Dad. As well as car maintenance, at College. And lots of other stuff too. I am having to relearn a great deal, after a Traumatic head injury, so at least I am lucky enough, to have a passion and interest... At the time of life, many folks are resting on their Laurels!!

[@ThomasAndersonbsf]

watching this again, :) and the chair/stool/table transition discription is so apt for this, it really does seem to be a perfect example of what you are about to discuss about the differences of the battery/supercapacitor/capacitor traits and how many of these can be in any two or all three while the items are still in one of those three classifications, What I like about it is that by defining the characteristics that fit in each and explaining how do to a lot of them, someone could use your explanations to make a custom blend of these for any one of a number of various uses each one different in needs and yet each version fits that need quite well even if it wont do the other things in the list that are so vastly different in demands XD. Thanks again on going back and clarifying some of these things, while I feel I should have the understanding for some reason much of these rabbit holes of info and ideas being so important were still places I completely missed.

[@oddjobbobb]

Thank-you thank-you thank-you! I have been trying to solve this question since I watched you first capacitor YT. I am glad to know that there is no clear delineation. That’s sort of what I thought. Thank you again Robert for taking the time to make a YT that must seem almost trivial!

[@jessicalee333]

Really excellent epistemology lecture. Categories and definitions are things people created - TOOLS to navigate reality, not reality itself. Use them as long as they are useful, and drop them as soon as they are limiting. The real world and nature and forces and even people have too many grey areas for us to cope with, but when we have to face a grey area we can't just retreat to our comfortable categories and say anything that doesn't fit is prohibited or doesn't exist. The messy version is the real world, the clean version is the fake we made to make things simpler for ourselves (and it would be hard to understand anything if we didn't). It brings to mind Magritte's painting of a tobacco pipe labelled "Ceci n'est pas une pipe." (This is not a pipe). No matter how perfectly it represents the thing, it is not the thing. If it were a pipe, you could smoke it!

[@glennwebster1675]

You explained it very well. Unfortunately a lot of people just want a free high amp hour battery that someone else developed ... Great video, keep em coming.

[@barry2718]

A wonderful explanation and it has really helped the understanding of this complex topic. Another point I would like to add is that capacitors and super capacitors charge and discharge on an exponential curve. Batteries tend to have a much flatter charge and discharge curve. With the use of modern day high efficiency dc-dc inverters a variable input voltage from a discharging super capacitor can be converted to an almost constant voltage and it would then appear very similar to a battery. Available power storage is also dependent on low internal resistance. Electrolytic capacitors are quite low but some super capacitors can be a bit higher. Batteries are still the winner here I believe with very low internal resistance but I could need correcting as I am not up with the latest developments. Great video and loved the chair versus table metaphor.

[@TheSadButMadLad]

Good example about the difference between a stool and a table, it's the function not the look that defines it and being fixated on the look can take you down the wrong alley. In these trying times, it's a good analogy to use in terms of race and identity. So it's better to look at a person's function or personality rather than their identity or race and to get fixated on race is going down the wrong alley.

[@NorthernKitty]

I'm feeling much better about my fuzzy understanding of the differences being due to the differences actually being somewhat fuzzy. 😋 And any technical explanation that involves balloons (or flowers, for future reference) will automatically get a "thumb's up" from me!! 😄

Fantastic discussion Robert! Watching your videos is inspirational. I picture you as the modern day equivalent of a Maxwell, Faraday, Edison. Only hope you discover some brand new property / characteristic of some combo of materials that provide vast energy properties! Couple of quick (and maybe silly) questions but ... 1. In quite a few of your vids there is some sort of 'sheet metal' noise at various points. Is there a nearby shop ? 2. What are the makes and models of the two pieces of test equipment behind you under the window ? 3. What are the white grid-like structures protruding from the windows, some sort of drying racks ? Thanks and keep up the great work sir!

[@kennybentley1161]

you said some things that were really interesting to me because I never really thought about them, like the double layers on the carbon (I thought double layers were mostly found in plasma physics and space), and that a traditional electrostatic capacitor is kinda like the electronic version of two magnets. I'm gonna let those rattle around for a bit. I love when you explain things explanations probably the most. my favourite one still is the explanation for the strange capacitor video :)

[@ThomasAndersonbsf]

ah another water analogy for explaining electricty I love it, also I love the way you broke down the dielectric effect and it explains how pulling the metal away with out releasing the molecules in the dielectric was why RWG was able to reassemble his after touching it all with his hands and getting nothing but yet once put together the power zapped back out of the giant capacitor he made with I think PE plastic sheet or teflon or something, and two big thick aluminum plates :)

[@biogreenz6613]

What a very complicated topic, thank you for breaking it down in such fine detail. I like the idea of solar and capacitors but I've always been a bit intimidated because lack of understanding and risk of shock. They seem like a good buffer to use as for the load from panel to capacitor to DC converter or ac inverter. I like the idea of usable solar energy with a detected battery but I guess in that senario it might be concierge a battery idk. Have you tested all the new buck boost converters from China lately? I don't know why but I'm fainted by there different specs. They also seem to do well from a panel to a load apliance. Great video!

So it's like Darwin talked about in the Origin of Species. What we categorize today as clearly different species would become far more of a grey area if we could have studied the creatures millions of years ago before the genetic branching took place. In this case human "fiddling about" may come to separate the components more in the future but at this point in time the divisions aren't as clear. Very nice job and kudos of a very impressive use of your lock-down time with video and project production at an all time high.

[@shortbuslife3440]

Hi Robert thanks for explanation, not sure if you remember in our discussion, I mentioned the electrolyte briefly and I suggested a form of sodium silicate may be practical from the research I'd done, part of my theory was that the sodium anon and hydrogen anons have opposite charges, meaning that instead of only getting say -2.1v from sodium (can't remember exact voltages or polarity) you also get +3.6v from the hydrogen giving a combined voltage of say 5.7v per cell, as sodium silicate poly/nonahydrate could also be mixed with carbon and then baked into a form of glass wouldn't this hold both chemicals in position but still allow the anons to flow easily through the carbon or have I got this wrong?

[@12thsonofisrael]

So many folks have not sat in a lab where there is no instructor, only text and tools. While there is much power there for learning how to learn, having an instructor talk about a subject using his or her on concepts is more like watching a ship's captain vs a teacher. The watching the captain teaches you to respect the art of knowing how finesse comes from experience. The teacher returns you to the text until you can reproduce what the book teaches. Which can be crippling.

As super capacitor technology progressed I always wondered if it could be combined with battery technology to create a hybrid that took advantage of the desired characteristics of both. A battery that stored energy, charged, and discharged rapidly. To some extent that is happening. Although the same result is achievable with improved discrete devices a single package could eliminate bulk. As you said though, the distinction is starting to fade. As both technologies advance I suspect the distinction will further decline,

Capacitors are an interesting subject and not straight forward. I have some in the shed that would blow the tip of a screwdriver away! Don't ask how I know! They are quite large and store up a lot of energy, they can be made to release it slowly or all at once, all at once can be quite spectacular. They are of the size you do not want to play with. I had even bigger ones, but I got rid of them as they were just to dangerous to keep if they got a charge.

[@philipvernejules9926]

.......I trust you're aware that they bounce back after what appears to be a completed discharge. So the next day they'll still deliver a shock. Why is this , and has any tertiary student done a PhD in the matter, it's rhetorical statement .

[@scottthomas6202]

In the words of my grandfather , " Few things are written in stone"... there's a lot of gray areas in real life . I think some city buses use capacitors instead of batteries , and it makes sense. Frequent short trips , and quick charging while people are getting on and off the bus. I would guess these supercapacitors would have a far longer life than batteries for that particular purpose.
