Steven Hiller - Elon Musk started out thinking super-capacitors were the ultimate energy story solution, but the physics just don’t pencil out. They’re very seductive and definitely have huge advantages over batteries in many applications. But for cars....not so much. People don’t seem to realize how much power modern LiOn cells can pump out. Obviously, super caps will blow away any battery technology, but LiOn cells are good enough to throw a 4000 pound vehicle forward at an amazing rate.
Bryan Noga Yeah, even using caps for Regen seems like you'd need at least 1kwh to absorb braking energy and provide acceleration. A bank of ultracaps to do that wouldn't weight that much but they'd take up a lot of space.
Bryan Noga I think the whole point was a mixture of both in a car. The caps to accelerate quickly and store the regen power as quickly then let the lithium basically cruise. That way the batteries will provide much more run time since acceleration really eats their power.
Steven Hiller - It probably depends on the car. I believe Ford hybrids have a 0.6 kWh (?) LiOn battery, but I’m not sure exactly how much capacity is actually used by the vehicle. A super cap would be a good alternative, and also have the advantage of being less sensitive to temperature & storage.
Bryan Noga A mix is best. Caps for the start and stop spikes and batteries for cruising. The batteries will last much longer if the don't have to pull the car up to speed.

Nice country. But dirty dirty electric power. Most their power comes from oil shale, which apparently is even worse than coal. not only it outputs outputs over 1000g CO2 per KWh (compared to coal's 800g), but also 46% of fuel turns into highly alcaline ash. www.electricitymap.org/?page=country&solar=false&remote=true&wind=false&countryCode=EE
They kinda are. Especially since they managed to do better then neighbour Latvia. They didn't loose 10% of country's population due to emigration. And it is much easier to do business in Estonia then in Latvia.

Know what...? Significantly more sun than you'd guess and still humane temperatures even in summer. Add to that: high education standards where a mere university degree doesn't qualify, startups by the dozens showing the country is filled with innovation, soviet inheritance as a mere reminiscence - why am I so settled now :-(
Robert is one of my favorite personalities on all of UA-cam. Not just because I'm fantastically interested in all things renewable, but also because he just seems like a really genuine person.
Oskar Rei in exUSSR most older people still speak plenty of Russian, you are going to be exposed to it no matter what. On other hand, you have a chance to practice your spoken English only with foreigners.
Loanword Eggcorn: I think they said that, but with BEVs there is always the issue of weight and size of the pack. These capacitors provide a small and light way of both "absorbing" and providing a large amount of energy quickly - i.e. for regen braking and acceleration. They also avoid the need to pull and push a load of current in/out of the battery which can cause degradation through heating.
The production value on this episode seems so high. Nice job on, well everything, camera control, framing, lighting, presentation, music, editing, all of it. Your stuff gets better and better :)
Let me pose this thought to you: High-End Car Audio Systems incorporate Super-Capacitors in them for large power spikes, because if powered by batteries alone, the amplifiers can't handle some of the peak spikes in power. The capacitors provide the extra stored energy to keep this from happening, smoothing out the few of power. This is an understood fact and has been for many years. So, why then, do you think incorporating this into larger scale power generation facilities is a stupid idea and/or a waste of money? One SMALL scale practical application I can see for large capacitors would be for lighting systems. The Goal Zero lite A Life 12 Volt 350 Lumen light could burn continuously for WEEKS on just one supercapcitor, and when the Supercapcitor is exhausted can be recharged in 90 seconds, and then run the light for weeks more. Yes, this technology IS in its infancy, but don't dismiss it out of hand. I'll take this over a Coal or Nuclear Plant, thank you very much.
Capacitors have been used for a very long time, and in fact most electronics could not work without them. What's new here is the technology and specifications. To claim that the US petrol and nuclear corporations will be able to stop this is naive. It's already here.
Brian Foote my response was to the paranoid delusional dude further up babbling on about CIA and industry wanting to kill off the technology. As for the economy of this, it clearly makes sense since they already have a large number of customers around the world.
Very good report,including the info in general about Estonia. I am 71 years young and think ultracaps are very cool. Now, if I can just figure out how to make a mould of my hood, doors, etc. . and still be able to use the old gas engine for rear wheels, what a fantastic gas saver it would be to drive the front with ultracap and integrate it with existing electronics. Just a dream, keep on making good vids and maybe I will learn even more!
Three points of note need to be made whenever talking about batteries vs capacitors: 1) Batteries do not "store" electricity, they convert electricity into (and out of) chemical energy. ie the energy is stored by change in chemical balance within the cell. This is why they are "slow" but "energy dense" Capacitors directly store electric charge, the lack of chemical reaction required therefore makes then fast but fundamentally poor energy density 3) The charge held on a capacitor is inversely proportional to the separation of the charge carrying elements ( C = ( E X A ) / d ), however the maximum voltage a capacitor is capable of withstanding (before charge "leaks" across between those elements) proportional to that separation distance. Why is this important, because Power = Voltage x Current, so high power requires high voltage, which means large separation distances, which means a smaller capacitance value. The current drive for higher system voltages for eMobility applications, which is likely to continue (as both efficiency and cost fall with increasing voltage), tends to start making capacitors bit players in the energy storage game (And if you think "hey, i can just put some capacitors in series, well, sorry, but physics has got a limit there too, as capacitance is the opposite of resistance, so put two capacitors in series and their effective capacitance halves not doubles!) 3) The energy stored in a capacitor is directly proportional to the voltage across that capacitor (U = 0.5 C x V^2). Unlike in a battery, where the chemical reaction is driven by the voltage difference, a capacitor therefore has a voltage across it's terminals that is highly dependant on the charge stored. This means that practical capacitor based energy storage systems require an active voltage converter (DC/DC converter) in order to maintain a reasonably fixed output voltage at all energy levels. That means the power limit of the system is not actually the capacitors themselves, but the power transfer capability of that converter (who's ultimate performance is inversely proportional to the voltage ratio required). Therefore, any meaningful cost comparison with battery storage MUST include the cost of that vital voltage converter, ie you cannot just compare the cost of a capacitor with a battery, and say "capacitors are cheaper". Today, significant capacitor energy storage has been only realised in high cost systems (buses, cranes, motorsports etc) simply because the cost and complexity of the necessary voltage matching infrastructure has made such systems un-competitive with chemical battery storage systems on small, or cost sensitive applications (ie passenger cars). And while chemical battery costs continue to tumble, driven by huge investment in massive volume production, that situation is not going to change any time soon imo..
More importantly, chemical batteries can provide more than enough power for typical use in an EV without capacitors, particularly for large capacity packs.
In day to day use, this can very useful for regen breaking, since batteries heat up the quicker you charge/discharge them, and heat damages them. So by implementing a capacitor along with Li-Ion batteries, you're charging up the caps, then transfering the power back the wheels when needed, or charging up the batteries at a slower rate. Think of caps as an energy buffer when regen breaking.
Capacitors are impractical for vehicles that need long discharge rate and high energy density, even Elon knows this, all they will be useful for is accelerating/decelerating very fast, possibly useful in electric supercars and like here in the bus but not used entirely on its own practically
ODI Idk: As far as I can tell from the first couple of minutes the battery cost can go down by a factor of 2 using ultra capacitors. Please watch the well laid out intro again. Not that you are wrong about the battery tech side of things, but as stated, ultra caps and batteries are not competitors.
Super Capacitors have high self discharge rate. Maybe good for busses not for cars or power storage.

epSos.de ...China has more than 300,000 thousands buses operating on this supercapacitor technology in Shenzhen city. Google it. People in US are prohibited to learn or to misconstrue about this wonderful technology.
What an absolutely beautiful presentation of a fantastic show and wonderful innovation from a great place. Well done Robert. One of the best shows you have done !
High speed railway connection Berlin-Warsawa-Tallin is under construction (check Rail Baltica). So this amazing country gets more accessible via public transport. They even consider a railway tunnel under the Baltic Sea connecting Tallin and Helsinki. The whole Baltic Area deserves our closer attention. 👍
'High' Speed Railway (HSR) has high speed only relative to slow speed railway and was disrupted years ago with trains or cubes moving in tunnels above or below ground in or near vacuum conditions:) It is disrupting in price at 1/10th of HSR, in speed at supersonic, in convenience with quiet, smooth rides...etc.
Earl Pottinger Simples! I admit!😏, I was sceptical of the "supercap" argument....... BUT I always believed the "enthusiasts" were proposing that they be a REPLACEMENT for the battery. NOW I understand that they are effectively "best friends".... (DUH!!!) I have to say, this is a akin to the moment I realized EV's would (eventually) be the future! The strange thing is, I have (for a VERY long time) been a fan of Formula One. It's becoming apparent (at least to me..... duh, again?) that this company is "involved" (if not in F1, in Endurance hybrids). The logic of the system *works*!
The camera work in this video is just remarkable, sumptuous even :) I enjoyed the capacitor discussion of course but more so the quick intro to Estonian use of tech and the gorgeous city views. You guys should do a travel vlog on the side.
This is absolutely brilliant. I believe that battery storage using Sodium batteries and super chargers will replace Lithium arrays, because Sodium is much heavier, and cheaper - much better for land based giant storage, but the MW Ultra capacitors is perfect for instant energy balancing requirements and is a MUST !
I've been waiting for so long for graphene-based ultra capacitators to come to market. And now Estonia has made this amazing product! Mr. Madiberk really seems to know his stuff. Also, greetings from Finland!
Fully Charged rocks. I've watched and been a fan right from the early days and I never fail to learn something from your fascinating, well-produced and thoroughly enjoyable videos. Thank you Rob and FC team.
I recognized the background as soon as I saw the opening scene. The old city in Tallinn is a fantastic place to visit. I also went to the Kuressaare Castle on Saaremaa and I had a wonderful experience and learned some European history that's not taught in western schools. Sorry for the interruption Robert...
Love this. The backstory about Estonia really made me appreciate the technology. I just make the interconnection between, history, culture, society and innovation.Mind-blown! More like this!
Finally some supercapacitor(er..ultracapacitor) that works. Finally some company who's not making long illogical promises and stating just the scientific facts. Yes, this is not an alternate to batteries, but a complement to it. Good work guys!! Future is bright.
Ultra capacitors have only a small stored energy/weight, but huge power/weight. Consider that, energy/power = time. Amount stored / how fast you use it = how long you can use it for. Small/large = tiny. So they are great for short duration high power applications. But used in combination with batteries they are fantastic! Great idea for commuter trains too. I love this channel!
I visited Estonia in my early teens; the first street Robert was walking down looked like one I went down back in 1999. The country was still at the tail end of recovering from the Soviet era at that point; I'm glad to see the Estonians are doing well these days.
Outstanding! Perhaps Ultra Capacitors are the missing piece of the puzzle. Regenerative breaking, lightening fast acceleration, making a renewable energy grid more reliable and more!
This has to be one of the best episodes of fullycharged I have ever seen. I never knew that about Estonia. From what you showed us it does look like a cute little german village. I then also remembered that it has some german lineage as well because it was part of Prussia at one point. Still though I am very impressed. I wish the US was this forward thinking.
when I started watching this video, I was thinking what would be the future? Batteries or ultra capacitors? But the answer I got after watching it is ESTONIA.
The video filming and editing quality increased exponentially on this one, well done. Don't know how much that ran you but there is no turning back now
I've visited Estonia in the middle of Winter. The worst aspect of that trip was the airline (Nordic/LOT), but the country was amazing - even in deep winter. And it's true, they're really having their eyes towards the future, and it shows.
Fascinating! Thanks for this very interesting and astonishing information. I visited Tallinn last year and it was nice to see it again. I loved the historical town centre. But I didn't know these incredible facts about Estonia.
As you have probably seen, there was another chamber inside. THERE is the vacuum. The box around it is a clean room and those are pressurized to keep everything from the outside from going in. The gloves are there if something in the production line fails. Then you can pressurize the vacuum and work on it without destroying the clean room condition. This saves a LOT of time.
Got to say, as a non-native speaker, I sometimes find it difficult to understand conversations whenever other non-natives are taking part in, specially Easter-Europeans. However, I'm loving this guy's accent. So clear in message and delivery, really impressed by the company & CEO
Thank you for your wonderful impressions about this little country ... we heard about so small. The future battery technologies coming from there ... unbelievable! Thanks
Technology emerging countries like Estonia learn so much from us in the UK and Europe, the main thing they learn is how to develop and learn new skills and take the lessons from us how NOT to do it. Well done Estonia for looking after your country and your people. :) (Another great piece Rob)
Australia: we're going to build next generation fiber to every household. Actually nvm, lets just make a frankenstein network of 30 yrs old copper, coax etc and call it a day.
Sounds like an excellent engineering proposal. The description of using capacitors for immediate storage/discharge is exactly what CPU chips do with an on-board memory cache. A cashe will store, say, a megabyte of memory cache so that the CPU doesn't have to go off-chip and wait on a memory request for information. That cache, while small compared to the total memory capacity of the computer, saves countless delays in getting a request completed. If, as the company states, such a cache of energy in an EV would double the service life of the battery, it's a win-win for everyone.
@@simonecipriano You can use both. The slash represents (and is usually said, when spoken out loud) as "per". Meaning, "every" or "over" (as in "over time", in this case). So something that is rated at 2kW, will consume 2 kW/hours over an hour period, (or 1kW/h every 30mins etc etc) - same usage as kilometers (or miles) per hour kWh is shorthand. For best practices too, you want to use is a capital "M" (for Mega) - to diferentiate from "milli" and if you want to get technical, a capital "W" for Watt, as that's its letter. (plus if you want to get even more technical, use a lowercase "k" (for 1000), as an uppercase "K" is usually to represent a binary "Kilo" (for 1024)
@@MrVelociraptor75 Hmmm, nope sorry, but you misunderstand. kWh is *not* kW per hour, but unstead is kW * (times) h. If something is rated 2kW it means it consumes 2kW or 2000 J/s. If you do that for an hour you get 2kWh. Another device which is rated 4kW run just half an hour will also have consumed 2kWh (4kW * 0.5h). As you can see you have to multiply the energy consumption in W (= J/s) by the amount of hours run to make the units work.
@@marcovoetberg6618 I'm hoping English isn't your first language and you've just had issues reading what I wrote. Because you're trying to argue against me, by saying THE EXACT THING I SAID! Although a slash "/" is usually used as a divide symbol in math, in physics it's used to represent "every" as I said in my first post. Mathematically, yes, you (often) multiply, when trying to work out how much power something is going to use, or has used. But that's not its meaning. Like I said, it's the same usage as speeds and distances. km/h is kilometers per hour. If you're travelling at 100km/h speed, you'll have moved 100km from your starting point after an hour. Same as light year, the distance light will travel after a year...
Nice to see Estonia in the news! I’ve been to Tallinn it was absolutely amazing.. there was very advanced tech right next to very old buildings and cobblestone streets.. I went back in 2004 and the internet was already fast all the way back then! Cool country and amazing tech coming from this company! Thanks fully charged for covering this 😎
This red head was awesome, he gave such good explanations of everything! One criticism which is for you, it would of been nice to actually introduce him, his name, his position. Seems strange to interview someone and not to give the audience the basics of the interviewee. Overall a very good video, thumbs up!
That was a great episode. I like the way that young man described the blend of the two storage systems. We have literally only started this trip to energy storage. Of course, when I say “we” I obviously don’t mean we in Australia. Regretfully, we are still talking about building new coal power stations. My embarrassment is overwhelming.
oh damn 100kW from such a small box. That's about 130HP from a package barely bigger than a lead acid car battery. I wonder how much energy was stored in there.
The datasheet on skeletons website says 63.9Wh (Wh, not kWh), so an absurd amount of energy in capacitor terms, but nothing compared to a battery of similar size
When I saw those massive high amperage cables get pushed apart like the video showed I was expecting the battery to blow up like a bomb. That is a obscene amount of power transfer in such a hyper short period of time. No matter how you look at it that capacitor augmented battery had a sky high power density/second. That's far higher than the largest submarine batteries.
A 1-farad capacitor can store one coulomb (coo-lomb) of charge at 1 volt. A coulomb is 6.25e18 (6.25 * 10^18, or 6.25 billion billion) electrons. One amp represents a rate of electron flow of 1 coulomb of electrons per second, so a 1-farad capacitor can hold 1 amp-second of electrons at 1 volt. It's not a lot, but the advantage is that it's rapidly available whenever it's needed, and can be just as rapidly recharged.
When I first say the title of the video I expected wild claims about supercaps replacing batteries. Pleasently surprised, the guy was very honest and provided clear explanation about the strength and weakness of his caps. Very well done.

Know what...? Significantly more sun than you'd guess and still humane temperatures even in summer. Add to that: high education standards where a mere university degree doesn't qualify, startups by the dozens showing the country is filled with innovation, soviet inheritance as a mere reminiscence - why am I so settled now :-(
I was inspired when I heard the ladies saying "twelve months" in Estonian.
@@Lazarov_Tweevles yes but only when seasoned well
Robert is one of my favorite personalities on all of UA-cam. Not just because I'm fantastically interested in all things renewable, but also because he just seems like a really genuine person.
What a no brainer, and a very impressive presentation from Taavi in what is probably his third of fourth language...
Ken MacIver seems like a very nice and smart chap.
Probably second language
Mark Phillips Second language is often Russian. 3rd or 4th more likely.
noop9k wrong, English is 1st foreign language. Russian or German is chosen as second language often.
Oskar Rei in exUSSR most older people still speak plenty of Russian, you are going to be exposed to it no matter what. On other hand, you have a chance to practice your spoken English only with foreigners.
You just made me want to visit Estonia. It looks awesome.
Reslly in stonia? Location?
Combining batteries with capacitors to split different types of loads is a very good idea!
I'm pretty sure they already do this, but usually put the capacitor just before the load.
Yea it's one of the most basic concepts of electronics, but to be able to apply it to high power applications is a big deal.
It's not needed. If the battery pack is large enough, it can give and take lots of power by itself.
Loanword Eggcorn: I think they said that, but with BEVs there is always the issue of weight and size of the pack. These capacitors provide a small and light way of both "absorbing" and providing a large amount of energy quickly - i.e. for regen braking and acceleration. They also avoid the need to pull and push a load of current in/out of the battery which can cause degradation through heating.
old idea. new tech. awesome humans. keep it werkin forward to new iterations... Estonia Rocks It Hard !! tyvm to everyone involved here.
The production value on this episode seems so high. Nice job on, well everything, camera control, framing, lighting, presentation, music, editing, all of it. Your stuff gets better and better :)
I just love how Fully Charged gives exposure to such companies ❤! Thank you!
This is Fullycharged at its best, more like this please, ^oo^
Hello from Estonia.
Let me pose this thought to you:
High-End Car Audio Systems incorporate Super-Capacitors in them for large power spikes, because if powered by batteries alone, the amplifiers can't handle some of the peak spikes in power. The capacitors provide the extra stored energy to keep this from happening, smoothing out the few of power. This is an understood fact and has been for many years.
So, why then, do you think incorporating this into larger scale power generation facilities is a stupid idea and/or a waste of money?
One SMALL scale practical application I can see for large capacitors would be for lighting systems. The Goal Zero lite A Life 12 Volt 350 Lumen light could burn continuously for WEEKS on just one supercapcitor, and when the Supercapcitor is exhausted can be recharged in 90 seconds, and then run the light for weeks more.
Yes, this technology IS in its infancy, but don't dismiss it out of hand. I'll take this over a Coal or Nuclear Plant, thank you very much.
this is an ad
Capacitors have been used for a very long time, and in fact most electronics could not work without them. What's new here is the technology and specifications. To claim that the US petrol and nuclear corporations will be able to stop this is naive. It's already here.
Brian Foote my response was to the paranoid delusional dude further up babbling on about CIA and industry wanting to kill off the technology. As for the economy of this, it clearly makes sense since they already have a large number of customers around the world.
"You can run a tank over it" *tap tap tap with knuckles* "Aah, yes its very solid."
Very good report,including the info in general about Estonia. I am 71 years young and think ultracaps are very cool. Now, if I can just figure out how to make a mould of my hood, doors, etc. . and still be able to use the old gas engine for rear wheels, what a fantastic gas saver it would be to drive the front with ultracap and integrate it with existing electronics. Just a dream, keep on making good vids and maybe I will learn even more!
Three points of note need to be made whenever talking about batteries vs capacitors:
1) Batteries do not "store" electricity, they convert electricity into (and out of) chemical energy. ie the energy is stored by change in chemical balance within the cell. This is why they are "slow" but "energy dense" Capacitors directly store electric charge, the lack of chemical reaction required therefore makes then fast but fundamentally poor energy density
3) The charge held on a capacitor is inversely proportional to the separation of the charge carrying elements ( C = ( E X A ) / d ), however the maximum voltage a capacitor is capable of withstanding (before charge "leaks" across between those elements) proportional to that separation distance. Why is this important, because Power = Voltage x Current, so high power requires high voltage, which means large separation distances, which means a smaller capacitance value. The current drive for higher system voltages for eMobility applications, which is likely to continue (as both efficiency and cost fall with increasing voltage), tends to start making capacitors bit players in the energy storage game (And if you think "hey, i can just put some capacitors in series, well, sorry, but physics has got a limit there too, as capacitance is the opposite of resistance, so put two capacitors in series and their effective capacitance halves not doubles!)
3) The energy stored in a capacitor is directly proportional to the voltage across that capacitor (U = 0.5 C x V^2). Unlike in a battery, where the chemical reaction is driven by the voltage difference, a capacitor therefore has a voltage across it's terminals that is highly dependant on the charge stored. This means that practical capacitor based energy storage systems require an active voltage converter (DC/DC converter) in order to maintain a reasonably fixed output voltage at all energy levels. That means the power limit of the system is not actually the capacitors themselves, but the power transfer capability of that converter (who's ultimate performance is inversely proportional to the voltage ratio required). Therefore, any meaningful cost comparison with battery storage MUST include the cost of that vital voltage converter, ie you cannot just compare the cost of a capacitor with a battery, and say "capacitors are cheaper".
Today, significant capacitor energy storage has been only realised in high cost systems (buses, cranes, motorsports etc) simply because the cost and complexity of the necessary voltage matching infrastructure has made such systems un-competitive with chemical battery storage systems on small, or cost sensitive applications (ie passenger cars). And while chemical battery costs continue to tumble, driven by huge investment in massive volume production, that situation is not going to change any time soon imo..
Max Torque questions is why do we need capacitors when will coming soon solid state batteries ?
More importantly, chemical batteries can provide more than enough power for typical use in an EV without capacitors, particularly for large capacity packs.
Yes, the video said they're using it for regenerative braking on buses.
well said!
In day to day use, this can very useful for regen breaking, since batteries heat up the quicker you charge/discharge them, and heat damages them. So by implementing a capacitor along with Li-Ion batteries, you're charging up the caps, then transfering the power back the wheels when needed, or charging up the batteries at a slower rate. Think of caps as an energy buffer when regen breaking.
Wonderful technology for buses, trains, and wind turbines.
This *will make electric vehicles cheaper* and the air cleaner for all of us !
Capacitors are impractical for vehicles that need long discharge rate and high energy density, even Elon knows this, all they will be useful for is accelerating/decelerating very fast, possibly useful in electric supercars and like here in the bus but not used entirely on its own practically
What will make EVs cheaper is simply a better battery, either solid state or graphene, but only when its well developed to the point that its cheaper
ODI Idk: As far as I can tell from the first couple of minutes the battery cost can go down by a factor of 2 using ultra capacitors. Please watch the well laid out intro again. Not that you are wrong about the battery tech side of things, but as stated, ultra caps and batteries are not competitors.
Super Capacitors have high self discharge rate. Maybe good for busses not for cars or power storage.
epSos.de ...China has more than 300,000 thousands buses operating on this supercapacitor technology in Shenzhen city. Google it. People in US are prohibited to learn or to misconstrue about this wonderful technology.
What an absolutely beautiful presentation of a fantastic show and wonderful innovation from a great place. Well done Robert. One of the best shows you have done !
The presenter should be given an award or something . As a renewable energy advocate my self , i found this very entertaining and informative as well.
High speed railway connection Berlin-Warsawa-Tallin is under construction (check Rail Baltica). So this amazing country gets more accessible via public transport. They even consider a railway tunnel under the Baltic Sea connecting Tallin and Helsinki. The whole Baltic Area deserves our closer attention. 👍
'High' Speed Railway (HSR) has high speed only relative to slow speed railway and was disrupted years ago with trains or cubes moving in tunnels above or below ground in or near vacuum conditions:) It is disrupting in price at 1/10th of HSR, in speed at supersonic, in convenience with quiet, smooth rides...etc.
Best program I have seen in a long time. Thanks for letting the guest talk in full.
NOW I GET IT!
Basically
Regen the CAPACITORS.
Use THAT energy to accelerate.
Use the BATTERY for cruising.
Simples!
Exactly, you got it.
Earl Pottinger
Simples!
I admit!😏, I was sceptical of the "supercap" argument....... BUT
I always believed the "enthusiasts" were proposing that they be a REPLACEMENT for the battery.
NOW I understand that they are effectively "best friends".... (DUH!!!)
I have to say, this is a akin to the moment I realized EV's would (eventually) be the future!
The strange thing is, I have (for a VERY long time) been a fan of Formula One. It's becoming apparent (at least to me..... duh, again?) that this company is "involved" (if not in F1, in Endurance hybrids).
The logic of the system *works*!
Amazing (well, not really) how many 'experts' here apparently don't........
Roger Starkey but use more components to connect these - not very cheap, unfortunately.
@@noop9k
If you add the capacitive unit, you're removing batteries, which compensates for the price. The benefits would outweigh the cost.
I love this video: Lots of explanations and more importantly lots of demonstrations. No shiny computer graphics or "artist renditions". So keep it up.
The camera work in this video is just remarkable, sumptuous even :) I enjoyed the capacitor discussion of course but more so the quick intro to Estonian use of tech and the gorgeous city views. You guys should do a travel vlog on the side.
This is absolutely brilliant. I believe that battery storage using Sodium batteries and super chargers will replace Lithium arrays, because Sodium is much heavier, and cheaper - much better for land based giant storage, but the MW Ultra capacitors is perfect for instant energy balancing requirements and is a MUST !
I've been waiting for so long for graphene-based ultra capacitators to come to market. And now Estonia has made this amazing product! Mr. Madiberk really seems to know his stuff. Also, greetings from Finland!
Thanks for showing a different part of the world in addition to the main feature in the video of Ultra Capacitors. Thanks Robert and the team.
I love all of your content, but, technology showcases like this are by far my favourite! Keep up the great work!
Absolutely amazing. Brilliant. You can see the future here.
That laser welder closeup...
Fully Charged rocks. I've watched and been a fan right from the early days and I never fail to learn something from your fascinating, well-produced and thoroughly enjoyable videos. Thank you Rob and FC team.
I recognized the background as soon as I saw the opening scene.
The old city in Tallinn is a fantastic place to visit. I also went to the Kuressaare Castle on Saaremaa and I had a wonderful experience and learned some European history that's not taught in western schools. Sorry for the interruption Robert...
Love this. The backstory about Estonia really made me appreciate the technology. I just make the interconnection between, history, culture, society and innovation.Mind-blown! More like this!
Finally some supercapacitor(er..ultracapacitor) that works. Finally some company who's not making long illogical promises and stating just the scientific facts. Yes, this is not an alternate to batteries, but a complement to it. Good work guys!! Future is bright.
Ultra capacitors have only a small stored energy/weight, but huge power/weight. Consider that, energy/power = time. Amount stored / how fast you use it = how long you can use it for. Small/large = tiny. So they are great for short duration high power applications. But used in combination with batteries they are fantastic! Great idea for commuter trains too.
I love this channel!
Look how beautiful that country is. Wow just walking down the street looks amazing!
Shane Semler what made you leave America?
I visited Estonia in my early teens; the first street Robert was walking down looked like one I went down back in 1999.
The country was still at the tail end of recovering from the Soviet era at that point; I'm glad to see the Estonians are doing well these days.
Lot of graffiti.
Elite Clinical Research Also notice the lack of "diversity" :)
Agreed, I was just about to ask if you had ever visited Europe!
Outstanding! Perhaps Ultra Capacitors are the missing piece of the puzzle. Regenerative breaking, lightening fast acceleration, making a renewable energy grid more reliable and more!
Holy cow Fully Charged has 300k subs now Bobby! Brilliant job!
Thank you, 307,573 to be accurate :-)
themadplotter fully charged has come a long way. So professional and proper, and yet just as interesting.
Bravo!
themadplotter should have 300 million subs I think.
even the Cock Brothers have subscribed!

This has to be one of the best episodes of fullycharged I have ever seen. I never knew that about Estonia. From what you showed us it does look like a cute little german village. I then also remembered that it has some german lineage as well because it was part of Prussia at one point. Still though I am very impressed. I wish the US was this forward thinking.
This could be the answer to storing energy from lightning! I'm so excited to see how this technology develops over the next few years.
Or making lightning. muhahahahaha...
Now there’s an idea 👍🏼
that means ,, we can cope without fusion power ,
keep on dreaming. at least it does not pollute the environment
when I started watching this video, I was thinking what would be the future? Batteries or ultra capacitors?
But the answer I got after watching it is ESTONIA.
The video filming and editing quality increased exponentially on this one, well done. Don't know how much that ran you but there is no turning back now
What a wonderful place! Inspiring. Brilliant episode too, thanks Rob and the whole FC team!!
Wow another great video guys. Keep it going.
I've visited Estonia in the middle of Winter. The worst aspect of that trip was the airline (Nordic/LOT), but the country was amazing - even in deep winter. And it's true, they're really having their eyes towards the future, and it shows.
This is amazing the kind of technology you will see here in Estonia.
The production quality of this video is mind blowing.
Fascinating! Thanks for this very interesting and astonishing information. I visited Tallinn last year and it was nice to see it again. I loved the historical town centre. But I didn't know these incredible facts about Estonia.
Two things: 1) That ultra-capacitor looks to be the beginning of a game changer, and 2) Now I want to go to Tallinn! Great vid.
"...that deep vacuum."
"In here?" pointing at inflated balloon gloves sticking out of pressure chamber.
"Yah, yes."
🤫 Luckily I did not had to search long after that post. 🤔My thoughts were: "What a strange vaccuum should this be?! 🤨 Has the physics changed?! OMG😳"🤣
As you have probably seen, there was another chamber inside. THERE is the vacuum. The box around it is a clean room and those are pressurized to keep everything from the outside from going in. The gloves are there if something in the production line fails. Then you can pressurize the vacuum and work on it without destroying the clean room condition. This saves a LOT of time.
@@te0nani Thus proving the inverse relationship between humorous observations and technical truth. ;)
Double Glove (glove-in-glove) set-up
Hmm, I just thought the gloves had enough natural rigidity to them to make them default to that form.
Inspirational. My hat is off to the company, and to the country...
Love the tidbits of history at the end, great video!
Got to say, as a non-native speaker, I sometimes find it difficult to understand conversations whenever other non-natives are taking part in, specially Easter-Europeans. However, I'm loving this guy's accent. So clear in message and delivery, really impressed by the company & CEO
Two things happened after watching this video -
1. I want an ultra capacitor pack.
2. I want to visit Estonia.
Hahaha, the back of the queue is that way!
bit difficult at this juncture
Thank you for your wonderful impressions about this little country ... we heard about so small. The future battery technologies coming from there ... unbelievable! Thanks
It's got electrolytes, it's what ultra-caps crave!
I feel both pleased and saddened that I got the Idiocracy reference the second I read it.
you mean - like from the toilet ?
Brawndo it's got electrolytes
Hilarious. What a great and perfect crypto-reference.
(Looks around USA)Idiocracy seems quite utopian now.
Technology emerging countries like Estonia learn so much from us in the UK and Europe, the main thing they learn is how to develop and learn new skills and take the lessons from us how NOT to do it. Well done Estonia for looking after your country and your people. :) (Another great piece Rob)
Great film work and fantastic editing, Really enjoyed the B-Rolls loving seeing robots work!
Very good video. Im using ultra capacitor pairing with my 12v batt, 4 years later, the car batt still going strong.
Estonia very beautiful country.
Amazing technology. Makes me hopeful for the future.
Great video. So good to have real science, and a start-up that is delivering a product, in high quantity, and is not a pipe dream company.
This is the very first productionised use of graphene I've seen, and I'm so glad it's cheap to produce. Solid state has arrived.
Two times the specific power and 3 times the specific energy of skeleton ultracapacitors: www.nawatechnologies.com/en/products/
One of the most informative and well shot documentaries I've seen on youtube.
Much can be accomplished when you have a leadership focused on advancing the common welfare of the country. Thxs for the primer on super capacitors.
Ben....agreed, unlike Britain's group of EU led rabble we call our "Government"
The internet = knowledge = progress 😃 Notice the new and expensive cars amidst well maintained environment and ancient buildings 😃
Wow, Estonia really does sound like a nice place to live. Thanks for the insight!
Love these vids so much 😚
Tallinn is a great city to visit and the people are lovely. Been many times winter and summer. Great episode thanks!
~19:00 Cool climates may or may not have less sun, we often sunburn skiing. Solar panels work more efficiently in colder weather.
This is a good rational explanation without the repeated hype about the technology!
Estonia: "Internet is a basic human right"
Uganda Gov't: "People must pay a special Tax to use Social media after paying highly for the internet"
Australia: we're going to build next generation fiber to every household. Actually nvm, lets just make a frankenstein network of 30 yrs old copper, coax etc and call it a day.

thanks for the love .....you really sounded sincere and Viva Estonia........xoxoxoxox
Thanks for the video, really good. I was looking for these detailed explanation or ultra capacitors
Sounds like an excellent engineering proposal. The description of using capacitors for immediate storage/discharge is exactly what CPU chips do with an on-board memory cache. A cashe will store, say, a megabyte of memory cache so that the CPU doesn't have to go off-chip and wait on a memory request for information. That cache, while small compared to the total memory capacity of the computer, saves countless delays in getting a request completed. If, as the company states, such a cache of energy in an EV would double the service life of the battery, it's a win-win for everyone.
very informative and inspirational for the future ..more videos like these please..
Gorgeous Camera Images. And handles the contrast range so well on those outdoor shots
This guy is awesome!
He’s even got a ginger top like a Duracell! 😁
True. Delightful chap indeed. You gotta love tech guys that can eloquently combine science and business talk.
I reckon he’s wearing a two door coupe.

Red hair is a Neanderthal genetic trait. Must have been a smart type of human.
Oh the production quality. Brilliant video and beautifully shot.
We don't use Kw/h, we use Mw/s.
Kwh without /
@@simonecipriano You can use both.
The slash represents (and is usually said, when spoken out loud) as "per". Meaning, "every" or "over" (as in "over time", in this case). So something that is rated at 2kW, will consume 2 kW/hours over an hour period, (or 1kW/h every 30mins etc etc) - same usage as kilometers (or miles) per hour
kWh is shorthand.
For best practices too, you want to use is a capital "M" (for Mega) - to diferentiate from "milli" and if you want to get technical, a capital "W" for Watt, as that's its letter. (plus if you want to get even more technical, use a lowercase "k" (for 1000), as an uppercase "K" is usually to represent a binary "Kilo" (for 1024)
@@MrVelociraptor75 Hmmm, nope sorry, but you misunderstand. kWh is *not* kW per hour, but unstead is kW * (times) h. If something is rated 2kW it means it consumes 2kW or 2000 J/s. If you do that for an hour you get 2kWh. Another device which is rated 4kW run just half an hour will also have consumed 2kWh (4kW * 0.5h). As you can see you have to multiply the energy consumption in W (= J/s) by the amount of hours run to make the units work.
In other words: 1 KwH = 1000 W * h = 1000 (J/s) * h = 1000 (J/s) * 3600s = 3.6 MJ
@@marcovoetberg6618 I'm hoping English isn't your first language and you've just had issues reading what I wrote. Because you're trying to argue against me, by saying THE EXACT THING I SAID!
Although a slash "/" is usually used as a divide symbol in math, in physics it's used to represent "every" as I said in my first post. Mathematically, yes, you (often) multiply, when trying to work out how much power something is going to use, or has used. But that's not its meaning.
Like I said, it's the same usage as speeds and distances. km/h is kilometers per hour. If you're travelling at 100km/h speed, you'll have moved 100km from your starting point after an hour. Same as light year, the distance light will travel after a year...
Nice to see Estonia in the news! I’ve been to Tallinn it was absolutely amazing.. there was very advanced tech right next to very old buildings and cobblestone streets.. I went back in 2004 and the internet was already fast all the way back then! Cool country and amazing tech coming from this company! Thanks fully charged for covering this 😎
This was the best one yet❤️
You always seem to find the best people to interview! And the best hosts aswell of course.
This red head was awesome, he gave such good explanations of everything! One criticism which is for you, it would of been nice to actually introduce him, his name, his position. Seems strange to interview someone and not to give the audience the basics of the interviewee. Overall a very good video, thumbs up!
8 out of 10 Estonians are redheads.
It's great to listen to articulate people talking knowledgeably about things they're good at!
and I enjoyed listening to Taavi too...
That discharge with the heavy duty cables was probably in the range of 1-4kA... Even stiff thick cables start to do weird stuff above 1kA.
That looked like the 170v/53F module that they have on their buy me page. That would be quite a bit of power.
I guess they discharged it through a resistor. I would expect a much more dramatic (dangerous) cable movement with a short circuit
Thank you all for sharing useful information on ultra capacitors. Really remarkable. Thanks from Jawaharlal Bharat INDIA 🙏
Cool, didn't know Skeleton was made in Estonia.
The video is inspirational. 🇪🇪 Success story about Estonia, a country with highly educated scientists!
Video on the pikes peak car coming soon?
That was a great episode. I like the way that young man described the blend of the two storage systems. We have literally only started this trip to energy storage.
Of course, when I say “we” I obviously don’t mean we in Australia. Regretfully, we are still talking about building new coal power stations.
My embarrassment is overwhelming.
oh damn 100kW from such a small box. That's about 130HP from a package barely bigger than a lead acid car battery. I wonder how much energy was stored in there.
not a lot 100 kW only for 1 second so 100 kWs wich is 0,02778 kWh
The datasheet on skeletons website says 63.9Wh (Wh, not kWh), so an absurd amount of energy in capacitor terms, but nothing compared to a battery of similar size
When I saw those massive high amperage cables get pushed apart like the video showed I was expecting the battery to blow up like a bomb. That is a obscene amount of power transfer in such a hyper short period of time. No matter how you look at it that capacitor augmented battery had a sky high power density/second. That's far higher than the largest submarine batteries.
A 1-farad capacitor can store one coulomb (coo-lomb) of charge at 1 volt. A coulomb is 6.25e18 (6.25 * 10^18, or 6.25 billion billion) electrons. One amp represents a rate of electron flow of 1 coulomb of electrons per second, so a 1-farad capacitor can hold 1 amp-second of electrons at 1 volt.
It's not a lot, but the advantage is that it's rapidly available whenever it's needed, and can be just as rapidly recharged.
It was impressively small and powerful. Only a little energy though, because this is the megawatt-second business, not the kilowatt-hour business!
Your videos are so interesting that even 20 mins feels like 2 mins .. Amazing work mahn .. keep up your good work
If you can do this for acceleration in cars, could capacitors help in home circumstances of sudden load, such as in hair dryers and toasters?
not necessarily because the load compared to the mains(in a properly wired house) is not much.
Mad props to your camera person who seems to have an amazing ability walk backwards for roughly .5km.
Did you know that if you turn around and walk in the same direction, you're going forward? :)
