  • I've had a few people point out that my $1000/kg price for graphene is way overblown, since GMG (the very company I talk about in this video) have claimed to get the price down to $2 per kilogram. I kinda sorta just a little hinted at the fact that they are bringing the costs down, but I didn't put it into numbers. That is really something I should have explored more in the video and looking back it was a missed opportunity because that's an important and interesting development.

    • Tech Nerd Stiffy? Hmm, that would be a TNS I guess. Joe the sesquipedalian for the average guy.

    • Outstanding work. I had to play it three times, not because of the subject (I'm an electrical/mechanical/software engineer) but you speak WAY TO FAST, and the video did not have the 0.75x or 0.5x speed control. Great work and explanation. Thank you.

    • @Pz Kz it's coming from methane, that's a fossil fuel.

    • Joe, what are your thoughts on Lake Mead? Can it be saved?

    • Thank you for the follow up

  • Don't forget, just like graphene Joe, you still have potential. It doesn't matter when you tap into that potential, just that you do. And I think this ID-tv channel is a great platform to get out science based material and delivers it in a way that is understandable. Thanks for sharing your potential!

    • But can he get it flattened to one molecule big and 10 tennis fields big tho?

    • Joe, you are not a loser ... anymore.

    • I too am a graphene kid...

    • Your comment had so much potential. But I reached my capacity for the repetition very quickly. Frankly, nothing could induce me to get charged up about your comment

    • Shame its shackled in a super complex structure of bonds 🤣

  • Incredibly good video Joe!

  • This reminds me of early Li-ion. Took 20 years before it filtered in the market when I discovered it working at a big alkaline battery manufacturer. At the time Li-ion was already 20-30 years into development. These things take time indeed.

    • Yeh bro more like 20 to 30 years of cast offs from over orders and fake crap out there making it worse 🤣

    • @Memo.A Graphene is still the technology with the some of the best results, if we can work out all the kinks and funding. I have high hopes.

    • Wow so there is hope on graphene ones

    • @abj totally agree.and the projection is real

  • This video has made me more optimistic about graphene, I was starting to look at it in the same way as nuclear fusion. A wonder technology that will change everything, which is perpetually 'just around the corner'. Here's hoping graphene is 'just around the corner'

    • I love how far tech is coming! Very good video Joe thanks for all the time you put into it!

  • Your puns had my inner dadness chuckling so hard. I watch your videos every week because you make them great, thank you Joe!

    • ok

    • something like Solid State Batteries which look good on paper, and can power a car for a thousand miles, but can't power themselves off the lab test bench and INTO a car. T

  • I feel strongly that thermoelectricity will have a materials or physics driven boom in our lifetime. I’ve seen things like flashlights already that charge from the warmth of your hand. What kind of tech would we see if the efficiency doubled or tripled?

  • AWJ is like a weekly vitamin pill for my brain! I love it and I always look forward to the next ep. I donate 1 dollar per month. Not much.. but if a bigger percentage of the subscribers does the same we can all enjoy AWJ now and in the future!

    • other opportunities out there! Thanks, have been a big fan of yours for couple of years now.

  • INTERESTING and entertaining, as are all your videos. I am like you; whenever I hear the words "battery" and "breakthrough" in the same sentence, I just immediately think of something like Solid State Batteries which look good on paper, and can power a car for a thousand miles, but can't power themselves off the lab test bench and INTO a car. The battery making it to actual commercial use will thus forever be "three to five years away". I call this the breakthrough horizon because it recedes as you approach. BUT, because you are awesome, I listen, learn, and enjoy, and adopt a "wait and see" attitude. All good wishes.

    • SSB are more than lab tech. Though not yet mainstream, I am aware of them being used in transportation (buses). They may not be coming out with a bang, but I think they're for real.

  • For that “Gifted kid” who’s now making content for ID-tv, sounds like the story for a ton of ADHDers. You have attained a level of success that is helping the world through informing and entertaining people, and I for one thank you for it.

    • @EngineeringVision puns are actually an indication of giftedness, and a ton of gifted kids become car and Star Wars adults. My college friend group is probably at least a Standard deviation about average in IQ, and we use puns every time we’re together, and next time will be playing a Star Wars game.

    • He doesn't seem like a gifted kid. Too many puns. He's more of a car guy who likes star wars.

    • @Calyo Delphi I was one of those gifted kids too, and once I hit "the wall" my sense of self worth deteriorated, I dropped out, and turned to drugs and alcohol to cope. I'm still struggling with my mental health 15 years later, being "gifted" is actually a curse.

    • @slumdog I was very fortunate to have a Special Ed. teacher for a mom that identified my problems, and also to have a father who could provide enough to get me the support I needed.

    • Fellow ADHD failed gifted kid right here. ADHD, dyslexia and dyscalulia all missed through school years, due to being gifted and developing some creative coping skills

  • Nice! I have been studying about Computer mice of all things, and mouse mods and a trend with it's wireless mice is that they keep re-engineering them to be lighter and faster. One of the ways is that the voltage that runs the system is dropping. Whereas older gens used to be 3.3v they are getting down to around 1.7 volts, as well as modders convert the wireless mice to LI ION to save weight and even some coin size batteries. I wonder if these new coin batteries are in someone's mouse? Love the puns here, nice work on the content team! I like the precipice it feels like we are upon with so many amazing technologies we are working so hard at to meet the urgency of the situations at hand. Great time to be alive! Cheers!

  • Joe I think a really good video could be a overview of experimental battery techs over the past few decades, explaining how long they spent in development, their capabilities, and if they ever made it to the market in any substantial way, and if they didn't then why did they fail? Seems like every year I hear of one or more new revolutionary battery tech(s), but seems like nothing ever makes it to the market.

  • A good analogy to graphene is plastic, and how long it took to become a common household product. And now we can't get away from it. So, yes. I anticipate a paradigm shift in technology once graphene production matures.

  • This is awesome. As an entrepreneur looking at my next opportunity after my current one has a good exit, I was looking to Li recycling. This video is making open my eyes to other opportunities out there! Thanks, have been a big fan of yours for couple of years now.

  • I've been waiting for this battery tech to start hitting the tech youtuber circles. I read the University of Queensland paper on this and have been excited about it for a while now. I really wish it were at the stage where it's ready for EV adoption because I am very much ready to buy an EV next year.

  • I serious laughed so hard at these puns. Made my day. Keep them coming! Love ya Joe

  • I used ultra caps in my car for my stereo lol... yes, they were extremely powerful... I loved them 😎 won 1st place in competition. I always knew they would be the future.

    • ok

    • ok

    • johnny depp then we might actually be somewhere right now.

  • As always very good. Thank you. Graphene technologies are rather like fusion. We can see there's endless possibilities but it's always 20 years away. The engineering of these things to be practicable is really hard, just maybe impossible... but that's nothing new for technologies we absolutely rely on: It's the reason why the majority of the world's most important silicon chips are made in about 8 factories mostly owned by two companies.* (A video?) *As an example. Given a terrorist could genuinely bring the whole world to it's knees with just a hand full of bombs it's a surprise more isn't made of this.

  • VERY interesting! There are so many electricity storage ideas out there right now. Something HAS to click and make it! I will be following this idea.

  • When Milwaukee Tools makes their pouch batteries for their cordless tools out of this, I'm sure they will allow us to use one battery for a full day of work. It would definitely be worth the money.

  • Incredibly good video Joe! I'm really digging the podcast too. I'd imagine the podcast interviews are possibly more difficult because you can't predict what your guest will say, and so a script is hard to stick to, but your interviews are evolving into a very professional format. Thanks for the brainy content!

    • before it became a stable power source, for instance. Graphene will get there, it's already moving in the right direction.

  • I love how far tech is coming! Very good video Joe thanks for all the time you put into it!

  • I work on the electrochemical properties of graphene. I've started to joke about graphene as follows: Graphene is the material that can do absolutely anything..... except leave the lab.

    • That's a bit harsh... graphene has been extremely successful in graphite pencils.

    • Graphene is exceptional. All those amazing electronic properties, and the most successful application is to mix it in concrete. The material is a joke. Also, people use "graphene" as a very loose term. Li-ion already uses graphite. And most of "graphene" that people throw around is more like graphite really.

    • @Dreckbob Bratpfanne oh, I also hope I'm wrong. The bottleneck is entirely in the production. The issues of applying graphene to the real world are not scientific, only engineering related.

    • Considering what it could do, i hope youre wrong with this joke as IBM was when they said there is a world market for 5 computers xD

    • @scvcebc That's it, only graphene can make fusion power possible.

  • 1.7 volts sounds like a great replacement for carbon zinc cells. The nimh batteries are just a little low for a lot of devices.

  • It's important to remember that it took scientists decades to develop and refine the production of silicon after its potential as a material was learned.

  • For that “Gifted kid” who’s now making content for ID-tv, sounds like the story for a ton of ADHDers. You have attained a level of success that is helping the world through informing and entertaining people, and I for one thank you for it.

  • Good episode Joe. I thought it was hilarious. Just the right amount of jokes to information ratio.

  • As a 40-something (equally questioning my remaining life's potential) I remember having a science poster of the Bucky ball in my bedroom in the nineties, and being quite excited about what it could mean for chemistry, computer science and all sorts of scifi. It's been slow going, apparently, both graphene and me...

    • My first encounter with Bucky balls was a novel by no less luminary authors than Arthur C Clarke and hard-scifi maestro Stephen Baxter, "The Light of Other Days". They had Bucky balls as the key to a micro wormhole generator that could look back in time! Talk about exciting potential!

    • {it been slow going, apparently, both graphene and me...}. But, you are making it. And that is all that really matters. Well, maybe not (ALL). I'm sure you would have like to complete this project many years past. So you can take the (next step). And you would have. Except for (politics). Any great paradigm changer like this, will cause all of the roadblocks the system has put in place (engineered to fail). This kind of tech will cause all of those (stops) to fall over. Of course politics will put the clamp on this awesome tech, for as long as possible. Turns out, (as long as possible), was this long. (Slow going), true. But it happened.

    • You should go to college!

    • Appreciate your audience! For supporting I’ll share with you some beneficial insight. Lets converse with the number above❤️

  • "Tech Nerd Stiffy!" LMBO 🤔😆🤣 I Love every video you & your team produce. Always educational, funny, & overall heavily entertaining. I hope that You & Your Family are doing great, staying safe & healthy Joe. Cheers, Stephen W Vernon BC 🇨🇦

  • I remember when graphene was discovered as something that could be extracted from electrical soot.

  • Thank you for using metric. It sounded so natural that I didn’t think about the extra effort you had to bring in to use grams and meters.

  • How much graphene can one make in a year to make a difference to the industry it is suppose to disrupt? The problem with graphene is in the production scaling like you've said, it is order of magnitude more difficult to solve compared to refining lithium.

  • Graphene is like fusion, we are always just a few years from getting it.

    • We have both, its just practical application that's holding things up.

    • well said 😆

    • Same with a breakthrough in battery technologies, always 5 year from now.

  • Love the content Joe. Random thought...Do you think there's a practical way to siphon off Antarctic methane for the production of graphene? Win win?

  • the "I Am Graphene" bit was so unexpected to me that upon beginning to laugh, my body decided to instead inhale some mouth juice. Thanks for the minute long coughing fit, Joe. I'll be expecting a full shipment in the near future plz

  • Decent video, but charging times for Li-Ion batteries have plummeted in recent years though! You can fully charge phones from 0-100% in about 10 minutes. Newest Chinese EV designs can charge at 500-700kW making charging time as short as 15-20 minutes

  • I have some "graphene" lipo batteries that I run in my r/c cars! Thanks for the vid, Joe. VERY interesting and entertaining, as always! :D

  • I rarely comment however when I do, it is because I enjoyed the content. Honestly, the best part, that provided light to my morning, was the puns and dad jokes. I don't know why but this video would not be as successful without it. Thank you for all that you do!

    • Delivery is key, Joe has a specific style and it does involve humour. Without that style of delivery the videos wouldn't be as successful (key being AS, they would still have people interested). Don't know why so many people in the comments either missed that or are getting worked up about it.

    • @Dawn Hendershot damn now my comment dont make sense 😂

    • @Nicholas Brosseau I never upvote replies to comments, but look at me now

    • @Joskus 🤪

    • That's very kind, thank you. :)

  • Cool vid. I've definitely read a lot on Graphene, & it'd be nice to finally see it implemented into a product. But like success, the easiest hardest thing to happen, is the 1st step.

  • I wish you had touched on the fact that the number amps we’re pushing is also a problem right now. Just because we make pouch cells that you can charge in 30 seconds doesn’t necessarily mean that you can pump an EV full in 30 seconds (not without making huge amounts of heat)

  • Another fantastic video Joe. Thank you for airing this positive advancement towards a better more sustainable world. It is always darkest before the dawn. I just hope humanity can reach its potential. I believe it can.

  • I just love Joe's self depreciating humor! 😊😊

  • Graphene is one of those technologies that, if delivered on, will solve a good chunk of humanity's problems. If people focused on it as much as they do on marvel movies or johnny depp then we might actually be somewhere right now.

    • @Luckytime Pretty sure they're already aware of the famous stuff buddy... but, do as you will.

    • @MoonBreath Yes, and I'm part of that 99% who can't contribute... except I can. Spreading awareness until it reaches the 1% who can contribute is contributing.

    • @Luckytime And with all that raised awareness space travel really took off after the moon landings right? Raising awareness isn't the answer to everything, especially when the issue is a specialist STEM problem beyond the abilities of 99% of the population: e.g. aerospace or graphene engineering. And especially when it's already a poster child! There's just no point in brow beating the average person on the street about it.

    • @BeyerT1 1. That's a strawman 2. They could contribute if they had the proper incentives which we can control on a society-wide basis

    • People who focus on marvel movies and celebrities wouldn't help solving any of our problems even if they had infinite lifetimes available to them.

  • Cool! Always great listening to you geek out..... Now, how's about you talk about that 'sand battery' breakthrough 😜🧑‍🔬

  • Thanks, Joe. You made me laugh out loud. And you taught me something. Bless you.

  • Once they remove the carbon from the methane, it would leave hydrogen. Maybe a possible fuel source?? Plus Methane Digestors are pretty simple to construct(seen some constructed from IBC tanks and food waste and Maine has some to fuel a power plant), so perhaps we could see processing plants that extract carbon from methane with byproducts of hydrogen fuel and compost! I'm probably hella oversimplifying but it is exciting.

  • Joe I loved the meta 4th wall break quite enjoyable!

  • I was still in highschool when everyone was hyped about graphene battery technology. I have a job, a wife and a kid now.. I'll probably be a grandpa before we see this technology in consumer devices

    • You can have a job, wife and kid IN high school

    • You can have a job, wife and kid within months of high school

    • It definitely feels that way.

    • @khhnator more of a problem with the cooling the super conducting magnets. Amongst many other things.

  • great to hear , and really dig the informative knowledge building style of your channel , even with humor so dry it makes the desert crave chap stick .....for real your comedy is great,,,,,, peace be with you amigo !!!

  • Good to see James Tour consulting on topics he's an actual expert in. Unlike OoL research.

  • Your puns had my inner dadness chuckling so hard. I watch your videos every week because you make them great, thank you Joe!

  • Thanks for the coverage on one of my favorite investments! Great job and happy 4th

  • Really liked that intro, Would be cool for Joe to get outside more often! Keep up the great work Joe!

    • @Joe Scott you need some graphene shorts :)

    • Considering that I wear shorts like 90% of the time, you'd think they would be less pale.

    • I thought it was a good visual and I was looking for excuses to finally use my drone. :)

    • I know... 17 years watching his casts and only today I learned that he has legs.

  • Don’t worry joe, I think you’re an S tier content creator

  • It would be great to see a combination of the two, a fast charging "buffer" capacitor that can offload it's charge to the larger and slower chemical battery, perhaps even work as a good power source for energy spikes. That way we get some of the benefit of the cutting edge without the cost of a complete conversion. We already see a similar kind of tech in storage drives for data, which is why large data transfers often start fast and then slow down once the super fast buffer fills and the input slows to match the overall rate.

  • I'm so excited for this technology.

  • 0:13 electrons does not move on the surface of a condctor. Electrons are bound in to the conductor itself just like a pipe of water would transport water but the surface of the pipe is also transporting water. A bit away to say surface, that means the more surface the more electrons. In reality we do not use radiators as wires. Because its not about surface,

  • Oh Joe you are so punny; don't ever stop! Love you for it as well as all that you bring to us!

  • You're the top-tier content creator to us, Joe!

  • what you missed also is that the methane cracked Graphene by GMG is PURE ! ! ! They could make an industry just around the graphene as a product

  • For the past five years, every week on ID-tv a new video is released which claims to present info on "game changing" battery tech.

  • If you could spin carbon nanotubes like cotton candy, it would be a perfect material for indestructible "forged carbon" parts and electricity storage

  • Joe, I've been using a graphine thermal pad for my CPU for a few years now, and it's awesome. I don't have to clean up any thermal compound when swapping out my CPU's or coolers.

    • @ContradictoryCrow Ofc. Nearly every paste is better than thermal pads, due to achieving a thinner interface between the surfaces.

    • @Psychx Sorry for misunderstanding. I don't know about that. Though you are not supposed to mount the cooler or plate very hard I any case... Doing that can cause a problem when you mount directly to the die no matter the thermal paste. As for creating a sanded like surface on the chip I have no idea if it happens. Though even if it does I am not sure how much it would effect the conductivity in the first place, since that is after all the job of any thermal paste, to close small gaps between the chip and the plate. But at any case thanks for the input I'll do some more research on the matter.

    • @nikos pant I was not referring to liquid metal at all, so pls don't tell me what I was talking about. The audacity... Anyhow, I specifically meant stuff like IC Diamond and CM MasterGel, since the topic was thermal paste containing nanodiamonds. Diamond paste that's applied directly to the die can in the worst case cause hairline fractures due to the mounting pressure (which can destroy the chip after a few thermal expansion and contraction cycles). Best case: the perfectly flat die surface gets ruined, which actually hurts heat transfer.

    • @Psychx No you are actually referring to liquid metal made by thermal grizzly. That is something completely different and it would destroy aluminum. Had he used that ,and the block that touched it was made from aluminum, It would crumble to pieces with in a day. And trust me he would know because the console would be bricked. Liquid metal is supposed to be used very sparingly, as to not leak by the pressure and on to other components ,as it is conductive, on the CPU or GPU chip itself with a bare copper surface connecting it to the rest of the cooling system (whether that is an air cooler or a liquid cooling system). I think the material thermal grizzly uses is gallium and it reacts with aluminum corroding it extremely fast.

    • In terms of raw cooling capacity, paste outperforms. But pads are great in at least two scenarios: Lots of part swapping, and making a fire-and-forget PC with an intended service life of 5+ years. Paste dries out eventually, pads don't.

  • When I heard about Graphene's properties a few years back I knew it was a matter of time for this to happen. After all batteries are the most poorly evolved part of technology mainly because they're really difficult to optimize. I think the reasoning behind why is because other parts of technology require precision and that sets back affordability while batteries can work with pretty much any quality of film and it'll only affect it's specs.

  • In the short term it is worth getting somewhat excited about, but this is what we need. I have no doubt we will make it, it's just a question of when and how.

  • I like this guys presentation. He is so expresive and informative

  • I wonder what the efficiency of these new batteries will be.

  • It is absolutely bonkers that we are still using individually package li-ion cells to make car batteries and this is considered cutting edge technology.

    • Too bad you don't know crap about battery engineering. Let me give you a clue. Energy per cell is purposely kept small so that if one sells shorts out and catches on fire it does not cause the entire pack to catch on fire. Every single one of GM's bolt EV battery packs had to be recalled because the large cells had some internal shorts which will easily propagate to the whole pack. Tesla does not have this problem.

    • @DrewLSsix uh what? they make one shape cell and they use it for everything.

    • @Critical Event no, no they don't. They have multiple battery forms just for their vehicles.

    • @Critical Event A point I think I was trying to make, but thanks for clarifying.

    • @Glenn Pearson One continuous cell is impossible. You still need to achieve high voltage.

  • man.. you are funny and accurate in one shot! , Thanks for your great work

  • Thanks for having an annual subscription for less, really love that content.

  • Nice to see more positive videos. It would cool to see a video on 2D materials of which graphene is included. I think your viewers would be interested in the different “purities” (forms) of graphene (one/ two layer, flakes, magic angle, etc.). Keep up the good work joes!

  • I love your sense of humour, never stop! 😂

  • At his point, for my sanity, I just assume that all graphene related technologies will not happen in my lifetime. Better to be pleasantly surprised than constantly disappointed.

    • It was Ben Franklin who said, “Optimist are often disappointed”.

    • It's already disappointing that the theoretical upper limit of specific energy is only 1000 Wh/kg, a tenth of what light fuel oil has.

    • There already is a battery chemistry much safer and more resilient then nickel magnesium cobalt or nickel cobalt aluminum. Lithium iron phosphate. The patent on those expired so now everyone in China makes them. You can get them in base models of their EVs as well as the Chinese made base tesla model 3. Pack density is comparable to nmc and nca batteries due to omission of liquid cooling.

    • Appreciate your audience! For supporting I’ll share with you some beneficial insight. Lets converse with the number above❤️

  • This will be widely available around the time we mainly use fusion energy.

  • So if graphene is such a wonder material, then how feasible is the production cost for getting graphene based applications out on the market. Production capacity seems to be the bottleneck here, if something is so brilliant and can potentially revolutionize our world, then why isn't production being ramped up as fast as humanly possible?

  • I feel like I have seen several shows/videos that have said that graphene is being used in roads, and buildings, which isn't exactly where I expected to see it first but I believe it has been used already.

  • The fast charging of graphene could open up the practical possibility of in road inductive car charging. Like how some busses charge at bus stops, only while in motion. At present that's not practical, but with fast charging you'd only need a charging road segment periodically placed.

    • excellent deduction

  • You are my favorite mid-tier content creator 💕

  • The thing that worries me the most when I consider buying a battery-powered car is: ... out of many times can I charge the battery before it is used up and need to be replaced? It's not cheap to replace the battery pack in a car ... 😥

    • then this battery is just for you - - 3,000 recharge cycles, compared with 600 for Li-Ion

  • For what it's worth, I'm still holding out for that space elevator too.

  • I remember the time when this channel hit a plateau, and Joe shared it in one of the videos. I think it was about 130k subscribers? Now I can see 1.4 M followers. Joe, you just don't have a potential, you actually made it :) You made a lot of people interested in science, that I am sure!

  • It's really in the details. But you know this. It's exciting to know that graphene seems to hold the key to that renewable resource we desperately need to combat the negatives associated with petroleum exhaust. I'll keep my fingers crossed just like you. Another great piece. Thanks for all your research and keeping us in the know.

    • @Crootcovitz you are talking hidrocarbons (LGP) which are a subproduct of oil refining... That was exactly my question. And I must explain myself better in the graphite matter: when piling up millions of graphene layers you will have a very similar structure to that of the graphite this does not mean you can get graphene from a pencil. A bit like diamonds: they are cousins, not twin brothers

    • @Neng Yang no storage power at all, it is a superconductor, which means its electrons are very mobile. Besides, it does not oxidize and does not take temperature easily

    • @Crootcovitz I meant its hexagonal structure of pure carbon is almost a carboncopy (lol) of that of the graphite. 1 mm of graphite contains around 3 million layers of graphene. Together with the diamond they represent the allotropic form of carbon, meaning they have within more than one physical form of its chemical element. And you were right, pressure is a variable to produce it. Radiofrequency allows you to fiddle with it too.

    • @Neng Yang I didn't say graphene makes energy. I said it's not made from graphite. Not on an industrial scale.

    • @Crootcovitz Graphene doesn't make stores it. Where you think that energy comes from.

  • Great to hear a local Aussie company is making graphene batteries!

  • Wonder how a graphane battery compares to the future solid state batteries being researched?

  • Huh. It's so strange to see James Tour in this context. He's well known as an abiogenesis denialist, and was roundly trounced by Professor Dave. Several times. However, he is (and Dave has said this outright) an exceptional materials chemist.

  • I was working on this last year. But being from a small reactive country I couldn't secure the funding and it flopped 😢 but I'm glad to see someone doing something about it.

  • I mean, there's still this wonder material Germanium, which can be made in hexagonal shapes (hexagonal SiGe) to emit light - directly inside a chip, allowing for laser emitting chips for communication or do calculations with light. SiGe can also be used to create bipolar transistors ... so I guess we could make tri-state processors with them or reduce the size of the current processors. And also Germanium is much "faster" than silicone based chips, as the electrons flow a lot faster through the material, and thus you can archive more clock cycles.

    • @Christopher Elliott well I think calculations with light could be a game changer, as light could be send through a vacuum in small silver coated channels between two or more chips, giving you nearly infinite bandwidth, as the result of the computation is available on the next chip as well, instantly. As this doesn't require additional clock cycles for writing and reading cache, memory or talk to IO, as it never needs to be "saved" anywhere, before beeing transmitted with a different clock speed, it could be a real game changer for clustering and multi processing as long as the runtime of calculations on the other chips can be predicted.

    • @Ruben Kelevra I've heard of research projects (but haven't heard of any results yet) of trying to use the diamond allotrope of carbon instead if silicon for ICs. Theoretically much higher temperature resistance, lowering the need for cooling electronics. I don't know about how quickly diamond based transistors can change state vs. silicon or germanium.

    • It's only been in use for..... As long as I can remember (and I'm "getting on")

    • Semiconductor photonics are limited in size by the wavelength of the light used to power them, making 5nm features impractical as you would need an EUV/Soft X-ray source of light, needless to say you probably don't want photons with that much energy flying around your nuts. This is a very well studied field, with a lot of applications, high density ICs will require a few breakthroughs that are not on the horizon now as far as i know though.

    • @CreativeType it's also not science fiction, silicon was just chosen in the early days because of the toxicity of Germanium (in the used GeAs form) and the more easy manufacturing. The Cray-3 has actually used them, because they were faster back then. But they company got bankrupt while building the Cray-4 and also the 244 MHz of the silicone technology back then has seen massive improvements, because of further miniaturisation. But as we really seem to approach the limits what's possible with silicone, we may just wanna look somewhere else. :) There's pretty new research on this topic from 2021, which claims Germanium could be used to reduce the amount of transistors be 85%, which could basically also cut down the energy consumption by a similar factor.

  • I love your content. Don't doubt yourself!

  • I just hope we can store enough energy to phase out fossil fuels

  • When Joe says “love you guys, take care” I know that all is right in the world…

  • I really hope Graphene isn't the next fusion where its always just a few years away. I remember learning about it for the first time when our house was tented. We got sent to a hotel and there happened to be a brief clip about it on the TV when I turned it on. It seems like it could become an amazing technology if someone makes a more efficient way to manufacture it.

    • Graphene is already use in some products. It just not the kind of products that was hyped when they first announced it.

  • I think graphene batteries would be the equivalent of a "killer app" for electric-alternative adoption. EV cars, for instance, I've argued won't replace gas-automobiles in America until we have a solution for "refueling" at the same speed as someone would expect to spend time at a gas-station - and this could be it. Even for low-capacity battery storage, if recharge time can become near-negligible you would see a huge increase in demand and also a huge interest in suppliers of electricity (since they should be seeing revenue potential from that too; literally selling electrical energy hand-over-fist to repeat customers).

    • you are awesome, I listen, learn, and enjoy, and adopt a "wait and see" attitude. All good wishes.

  • I was always told about my potential, even though I dropped out in the 10th grade. The second time in 10th grade. As well as the 3rd time in 10th grade. I dropped out twice. I also was in the 7th grade twice. I also went to 14 different schools, 15 if you count preschool, for the 13(or 14 years that I was in school!). Once I realized that I might be 23 by the time I graduated, I dropped out, waited 2 years, took the GED, and enrolled in college. I dropped out after 2 years. I hope graphene has better luck. If it makes it, and follows my life again, it will have some fun, be really happy, and then it will all come crashing down. 10 years later it will rediscover itself, and then it will find its potential and never look back. Some of us just take a little longer because we don't fit the system, and they like to tell us all the reasons, some having funny names and some just being strings of letters, as to why we can't function properly. After we get done kicking their ass because they are trying to insult us and tell us that we aren't capable, we actually discovery that what they said were our weaknesses were actually our strengths, and we proceed to start considering how we may be able to peacefully take over the world in a way that will usher in an age of discovery, and the peacefully and happy existence of humanity... TBC... oh! And TCB....

  • Any idea how many charge/discharge cycles this tech is capable of?

  • Imagine a drill battery that could recharge in a couple of minutes! That's gonna be be nice!

  • Joe, you are a top -tier content creator in my book!

  • Love the potential of this, been interested for a long time. But, you're right hearing about it and actually seeing it in use are two different things.

  • Hey Joe, I’m doing a mini binge, just want to say two things: A) thanks for the content B) ID-tv chose to put an ad about 5 seconds into your sponsorship announcement. Since the algorithm-ing of your stuff is a concern, thought I’d let you know. Thanks again for all you do!

  • I wonder whether one day we could tap energy from lightning, and store it in two-basketball court-sized batteries, made up of special material to stop them from over-heating or exploding...

  • Curiosity Stream/Nebula is seriously the best value in streaming service bar none. I rarely have the time to watch the time to watch anything on there but it doesn't feel like a waste at ALL! it's worth it for the handful of Nebula exclusives alone! Also Isaac, Mustard, and a few others have leveraged it really well by putting longer cuts of certain ID-tv videos on there. Spicier stuff the algorithm might not like or just big chunks that had to be edited out to please the algorithm, 100% worth. Just get it, you won't regret it.
