Yours is the most interesting and informative channel on the subject of renewable energy and environmental issues I have come across so far. Keep up with your fine work. Kudos and thanks.
For some reason I never get tired of videos about graphene😁. It's just too good to be true!
Yes, it is, isn't it?
That’s because it sort of is. We’ve made some real things with graphite-like materials, but the real thing is VERY hard to mass produce and the quality of it is directly related to how pure (in this case flat and contiguous) you make it
Probably spiders make it
@@markhaus yes we definitely have a lot of work to do to bring it too commercialization. I do think it will happen eventually, but we have to wait. Sometimes things take many decades to go from lab to commercial.
@JZ's Best Friend I think that one is considered a conspiracy theory. Cold fusion was discussed as a serious possibility decades ago but we now know it can't be done. At least not by our current understanding and technology. Graphene on the other hand, is real and has been produced. The trick is producing it at a commercial scale and of high quality. It will take some time, but it will happen. It took plastic like 40 years to change the world from it's discovery. People had long lost hope when it came out. But when it finally did it turned the world upside-down.
Now this is the first video on sustainability that shows that there's still hope and we should focus on science and technology as our means of adaptation to abrupt climate change.
This is an excellent channel. Love the range of explanations and the simple and elegant descriptions and illustrations.
Your descriptive inorganic chemistry is beautifully presented. Look forward to more on graphene.
Nice wrap up about graphene. You gave me plenty of information to use in my speech class, thank you.
Great to revisit this video Dave! Well done overview and so much more discovered since... it's incredible!
sir this channel is the best channel i ever seen
I obviously have heard of Patreon. However, I've never logged on. We live in a world that, almost from the beginning, we've come to expect content of all sorts to be free. It's almost that, because revenue can come from more oblique sources, the average rider can ride for free.Maybe that's not as horrible as it seems, as maybe it's just a changing business model. It does, however, add an element of "honor system" to our lives. If you're receiving something of value, your sense of both fairness and priorities are tested often. You're bright, articulate, selfless, more than fair, and informative. You present to the world a valuable thing. I was compelled tonight to pony up.
Exciting times. I shall read up on this. Cheers and have a good week.
@Zombie Vampires Yes, thanks. I've watched a number of his videos, he's always up to date.
Well presented doco, very informative and kept simple.
Great video. I look forward to the day we can 3D print this stuff.
Extremely interesting ,I thank you for this fascinating video please keep them coming Sir.
Wow it's been a while since I first saw a video on graphine, and now I have see your video and the exciting developments made in the last few years I can't wait for it to change the world.
I really like the water filtration aspect. As a father of a child who has NDI or in Layman terms, Water Diabetes, this is great news. I have always been worried about the water supply for him as he gets older. He has to drink at least two gallons a day.
Another great video, keep it up, its building momentum!! Thank you!
Thank you for a very interesting and well presented vlog on graphene and it possible uses. It seems to me that graphene will be for the 21st century what the discovery of laser was for the 20th century. Brilliant.
Maybe the 22nd century, if we ever get there.
I have enjoyed all your produced videos that I have seen, but this one is REALLY intriguing! THANK-YOU for your sharing all these things with yours truly.
Thank you for another great informative video. I am an organic chemist by training but even we chemists are not up to date on everything chemistry.
A few comments, with your permission:
1) The hexagon of carbons is not a molecule per se. A molecule is comprised of atoms covalently bonded but it is a finate structure. Graphene is a giant structure that you can enlarge or reduce, depending on how many atoms you connect to the structure. So a better name would be "the basic component of a giant structure / crystal lattice" and then you should immediately show the graphene picture.
2) I am not sure how much all the S Px Py and all the other things you mentioned were helpful. For most people it would sound like Chinese and it does not add any value to the video.
3) The screeching noise of the blackboard: big no-no.
4) I would consider presenting your name at the start.
5) Add some text before each link that you put in the description.
6) The about section of your channel is empty. That's a shame IMHO.
That's it. Great video and great channel. I hope you consider my comments as constructive.
Hi David. Many thanks for your feedback. Much appreciated and most definitely taken on board - I've learnt a few things reading your comments so I'm very grateful. I'll certainly consider all your suggestions for future videos. I'm not aware of the About section (I'm pretty rubbish on social media despite having a You Tube channel!), So I'll have a look for that and put something in there. All the best. Dave.
20 years ago they said we'll have fusion reactors and a bunch of graphene stuff. Oh boy, this summer is going to be great !
Graphene and conductive plastics are interesting materials. Good to see there is some commercial progress. This is why we need more funding for fundamental research.
Thanks for an update on graphene ;)
Now I understand covalent bonding. It is the same relation with key changes using cords that are common to different keys.
Graphite layer on paper, with a very fine wire just touching the surface sufficed as the 'Diode' in the first crystal radios
Fantastic video. Thanks!
What amazing bunch of new capacities Graphene has, I hope in my life time it is going to reach mass productions.
Looks promising....pity we didn't have it 50 years ago.
love this channel. but i have a request? @Just Have a Think. this was dated 2019. can you give an update on these porducts? have any of them actually made the jump to practical applications?
particularly the G-Concrete. and the batteries and capacitors?
You showed a plastic model of Graphene with identical single bonds between each carbon atom.
This is not the case. Each carbon atom must have 4 bonds in total. There are double bonds interwoven within the Graphene molecule and of course within the 2D Graphene sheet like structure. This ensures that there are 4 bonds around each carbon atom at any one time.
One way of understanding this a little better is to look at the structure of Benzene which is also a 6 carbon ring type structure (C6H6). Kekule was the first to propose a hexagon ring type structure for Benzene type molecules where single and double bond interchange within the ring structure. This effectively produces a delocalised cloud of electrons around the ring.
Its a small point but nevertheless very important
Very large point actually.
In the models of a sheet of graphene, I see three covalent bonds per atom of carbon, not four??
franklin russell as so often happens, for the sake of simplicity, the scientific details are neglected. You can get a correct explanation from a chemistry teacher or a chemical engineer.
And what exactly is there to keep it as a flat sheet, nothing else is a flat sheet
@@franklinrussell4750 2 out of 6 bonds are double ones.
enjoying the videos, really interesting
Brilliant presentation
Thanks for the cool vid! I understood they're currently using carbon nanotubes as conrete reinforcements, for the same reasons you propose graphene. Issue with that is; in processing and demolition this behaves comparable to asbest in the human body, meaning it's highly carcinogenic, for the same reasons as asbest is (it decomposes in thin long needles, destroying cell walls, DNA, etc. any opinion on that?
I liked the video in the first 30 seconds. When you said: "Graphene".
Excellent video, well presented.
Modeling is a tool to simplify things in both science and engineering disciplines. İf you Simplify something you'll surely omit some details. The point is to make its inner workings more understandable or just be able to make it work without the sheer complexity. You do an exalant work on "modeling hard scientific concepts" so that avarage Joe can grasp it. Please keep in mind this while being attacked "for being inaccurate" in your explanations.
Keep up the good work, İ love your videos and your way of explaining stuff. ( Despite being an scietifically inclined Engineer)
Graphene... the new Kale! I bet it works better for scrubbing my cast iron skillet than that week old kale I forgot in the fridge. I've been reading about graphene in my ScienceDaily feed for the past several years. Having worked for a few years in material science research, I am amazed at the amount of research in carbon fiber filtration, nanotubes, capacitors, and flexible non corrosive structural materials, etc. For those susceptible to despair, these are encouraging developments.
However the pace needs to accelerate rapidly. There are many hands idled by the preoccupation with next weeks sales figures or the new season of GoT or the relocation of facilities to who knows where while at the same time life saving, planet saving work goes wanting for lack of financial support. Get angry, get active or get out of the way.
I've been using coarse salt and damp paper towel pre cleans my carbon steel pan great!
@@greggbarber I guess I'll have to eat my greens afterall ;)
@@greggbarber we use glass, oh and microwaves
Fyi.. i test concrete for a living and there's a few companies here in the south that use various Graphene admixtures...
It works quite well.. just a small amount somehow changes the structure of the concrete.. when we break a cylinder in more or less "explodes" instead of crumble.. interesting stuff 👍👍👍
Graphene is constantly being made on industrial scale. Single large sheets are difficult to make, but smaller flakes are really simple to do and have tons of applications. Infact, i have made multiple kg of it myself.
That tape thing you did there, was not graphene, no where even close. Try sticking the tape to itself some 1000 times and you might get lucky and have there some pieces few layers thick.
Hi Skaltura. Thanks for your feedback. Sounds like you're an enthusiastic proponent of graphene. Just for clarity, I was of course perfectly well aware that I was not making graphene. It was a visual joke. I do those sometimes :-)
@@JustHaveaThink That was still an factual error, and you should have explained that you need to do that a thousand times or so :)
not according to Geim - he described exactly this process (with sellotape and a lump of graphite) in the first article I saw on Graphene (in NewScientist, many years ago). Press it on, tear it off - some of the flakes that are left stuck to the tape, the most transparent - hence the thinnest, he confirmed were only 1 atomic layer thick...
@@dickhamilton3517 he also described you need to do this hundreds of times ...
If you read my article, i did not say this does not work, but as shown; Is not graphene. Reading comprehension. It's a thing. :)
if it's a single layer from a graphite block, then of course it's graphene - that's what graphene is by definition - a single layer of carbon in a hexagonal 2D lattice.
It works because that's how Geim demonstrated it in the first place, and took electron micrographs to prove it.
i didn't expect the Graphene batteries to be out by 2020. I really hope they do. Thx for the video.
they weren't.
I would add the for the most promising technology to fight climate change is the methodology associated with regenerative farming. If a system to compensate farmers was implemented to have farmers convert to regenerative practices. Once converted and the practices established on each farm the incentives can be with drawn and the farms operated and continue to sequester carbon and super method continues to increase the land productivity creating a positive feed back loop sequestering carbon. This has to be a superior option to any patented mechanical solution. The added benefit is that desert land can be invested to create productive land. As 33% of land is desert this is a huge opportunity to sequester carbon and create productive land as a by product.
I can see multiple uses for OMTEC David..
bud found you not to long ago i love you thank you
Brilliant as usual
Great video 👍🏻
Your videos are top notch,and very inspiring, so thanks bloke !!!!!!!!
Could you do an update on this video? I haven't heard much about graphine in a while.
Is there any chance you could do a followup to this video? Thanks!
I really hope when this new graphene technology revolution happens companies focus on reaclaming carbon we've already used. Like those giant plastic islands in the ocean and the co2 in the air.
Excellent video again!
Great video as always!! 👍
beautiful channel you are incredible my friend. Jesus. love your references.
What about hempcrete and hemp bask for rechargeable batteries instead of expensive graphene ? Thanks for the great info
Dave, so what you are suggesting is that all I need is a spark plug, feed a rich mixture of acetylene into an old one cylinder engine, and just scoop out the graphene? Then mix that with Portland cement, add water, gravel and sand, and make concrete that is twice as strong? I'm liking that idea! How much of the soot from the engine do I mix with the Portland to get the best concrete? Is it that simple??
You have got a contaminated layer of graphite, with the ‘ print’ of adhesive on it. So is that the CoValent material?
The valence has to be compatible to make an electron bond. With no contaminant effect.
Freeman Dyson discounts the impact on any potential climate change as negligible. One of the factors that leads him to this conclusion is the development of technology that makes the issue moot. Ah technology with that potential is presented here. Thanks.
Fantastic!
Good one!
You should collect the diff. things you use on the shelf behind you...and later on you can always refer to an earlier program by pointing or use it again... just a little thought 😁
Wow. You could have been reading my mind! In fact I'm hoping at some point this year to start doing a second video each week (or possibly once a month) that just reports the latest news from the renewables world. I was planning to make a second little space in my cabin with a different background so as to differentiate the two types of program - and my plan was precisely to put shelves in the background with all the props I use in the videos. Great minds think alike!! :-)
Can I ask a question here about a related material i.e. carbon nano-tubes. Do they pose a health risk e.g. if you breath in a few thousand of those tiny things might it adversely affect your health.
Hi Dogphlap. You raise a very real concern about risks that governments appear to have been aware of for over a decade. Here's a link to an informative site...
www.ed.ac.uk/news/all-news/carbon-nanotubes
And here's some commentary taken from a UK Government review in 2009.
"Carbon Nanotubes
In 2004 the Royal Society and Royal Academy of Engineering reported that carbon nanotubes (CNTs) warranted particular attention due to their physical characteristics being similar to those of asbestos.
Following this, the Health and Safety Executive (HSE) published
guidance in June that year on management issues related to
nanomaterials advising that a risk assessment should be the first
step in ensuring effective control within the workplace.
In 2008 the University of Edinburgh published research showing that certain forms of CNTs could produce similar reactions to some types of asbestos fibres when injected into the abdominal cavity of mice.
While this research does not prove that CNTs will cause the same
effects as asbestos, it does prove that one step in the causal chain for mesothelioma is the same.
Subsequently, Defra sought advice from Cambridge University on the use of CNTs in consumer products. This work suggested that current uses and applications of CNTs were unlikely to present a serious risk to the public, but that further study was needed. As a result a CNT life cycle exposure study has now been commissioned by Defra which is due to report in summer 2009.
In addition, the HSE issued specific guidance in spring 2009 on the safe use and handling of carbon nanotubes, recommending that in the use of CNTs a high level of control should be exercised."
It's a subject close to my heart. My Dad's best friend had a summer vacation job on an asbestos farm in the early sixties and he contracted mesothelioma in 1980. He had a lung removed but he lost his battle in 1981. There's certainly no place for complacency here, and it does remind me of the importance of a holistic approach to considering all new, apparently 'world changing' technologies, to make sure we're not doing more harm than good. Thanks for leaving a very though provoking comment. Much appreciated. All the best. Dave
@@JustHaveaThink I much appreciate you taking the time to reply and supplying a couple of links. Perhaps carbon nano-tube workers will one day be required to wear respirators that incorporate a tuned graphene filter membrane to exclude particles of length equal or greater than the length that might be a threat.
Try with fullerene C60 molecule , which has circular ball shaped atomic model for solar PV cells, sphere has larger surface area and also a black body, which might improve efficiency from traditional 15 percnt
Cool video! I'm quite sure very little of graphene usefulness will enter consumer goods like batteries and such (maybe smaller super capacitors). Especially not concrete, since I surely don't want to be on superconductive bridge during storm. Maybe on dams or other highly monitored places. So, industrial use seems much more possible. I guess this is same as we discovered nuclear power and everyone thought we will have nuclear powered cars. It's just too dangerous to be left for common people to handle so reactive stuff if it gets to electric car batteries or similar. Discharge time when shorted would be extremely short. Largest impact for this tech is probably in advancements of filters, catalizators and other chemistry related stuff
While graphene is conducting, it is not a superconductor. A lot of bridges are steel which is of course conductive yet are safe during storms. Graphene's use in concrete will most likely depend on the cost. If graphene can be made cheaply, it will likely be used extensively.
i wanted to order graphene batteries for motorcycles. however the size available was only for hobbyist or those model size helicopters. that was two years ago. still not available batteries for cars of motorcycles. Whenever they will be finally available. watch out for huge changes. So far looking at the carbon batteries sound promising.
How disposable is the super-concrete?
A graphene molecule is a pretty open concept.
Robert Murray Smith has some excellent videos on how to produce graphene, supercapacitors and batteries. I love his CZcams channel FMG and his way of explaining science.
Very interesting stuff. If only we had a future?
I think that when you peel the adhesive tape away from the graphite you will not get a layer of graphene but a layer of graphite. If your right however, congratulations, you've just solved the problem of producing graphene sheets on an industrial scale!
I personally find the potential for increased efficiency of electric transmission mines to be most exciting.
Having studied a fair bit of physics and chemistry, I've learned to pay special attention to measurements and units. I can't help but be annoyed when people use units like KG or MM. It's somewhat understandable when marketing people do that, because they literally have no idea how to use or spell units of any sort. Just using numbers in a sensible way is challenging enough for them as it is, so you can't expect them to get the units right. However, in this case you included Nm in the video (at 2:55), which is must have been a typo or something, because I've seen you use units properly in other videos.
In case you're wondering, Nm stands for newton meters, which is an SI unit of torque. Using upper or lower case letters makes a big difference.
Is there going to be a graphene update video please?
he doesn't do updates, that would show that none of these announcements come to anything.
Pie-bon-bons sound yummy. This graphene stuff sounds very handy. I just wonder how it reacts to megacanes and tornadoes.
Okay, so if that's how one creates a "pristine" layer of graphene, then if one does that over say 10 feet of tape and measures the resistance across it, does it measure 0-ohms resistance (i.e. a short)? I bet it doesn't, but I never have tried it.
It's not a pristine layer, it's a jumble of tiny flakes.
Please post the links, great video. thank you

Hello, I have a gut feeling about you... maybe cause we’re about the same age, who knows. Anyway, I’m creating a risk assessment to try to jar the public to take a rational look at the cause, effect of atmospheric choices we need to make, to let them see we WILL pay for climate change, whether b4 or after the worst effects happen. Need a few people to look and give an assessment/recommendations. Could I impose your expertise?
What’s your educational and work background?
Hi Dave, a record view count. Looking forward to the next video.
Hi Dave. Yeah, this one seems to have been well received. Sorry there was no video this week - I've been clattered by this horrible winter cold going around. I'm more or less back up to pace now so normal service should be resumed this Sunday with a look at this new Lab-Grown meat technology that's on it's way to market soon. Have a good week. Dave
@@JustHaveaThink Sorry to hear about the cold. We've got a week's holiday so was looking forward to watching your next video, with time to reflect and research your topic. You probably saw this article from the BBC today www.bbc.com/news/science-environment-47283162 "Cultured lab meat may make climate change worse". Look forward to hearing your take on it all next week. A shot of whiskey might help the cold, but alas :-)
My wife is on dialysis and I heard that graphene membranes used in dialysis machines could significantly improve the quality of dialysis.
Strongs to you and your wife. My guess is that graphene will make a difference to dialysis, but only (primarily at least) in the aspect of cost. We may see home practical dialysis machines. I hope for you that does happen.
Sorry to be pedantic, but that plastic kit molecule you showed was "benzene" - which is the reoest unit within graphene, but by itself, it is NOT a graphene molecule.
Excellent video. But…
Graphene is both flexible and hard? Hard is just the opposite of flexible, it doesn't make much sense…
It is true the best solar panels available to the public are around 20-25% efficiency, but the best of the best unavailable due to its prohibitive costs and production unscallability are at more than 40%. They are used for very specific applications, like satellites. It is still a sizable jump if graphene allows to get solar panels to 60% efficiency, especially if they can be made cheap.
Use extra electricity to run a compressor to power a freezer. Make ice for air conditioning.
Another good vid David. Clear and comprehensible... dunno where you find the time do the research AND make the films so frequently. On a related concrete replacement note have you heard about Majd Mashharawi and her 'green cake' being used for building in Palestine? www.bbc.com/news/av/stories-46074563/what-is-green-cake-and-why-did-this-woman-invent-it
Any updates on graphene manufacturing?
same update as 2 years ago, absolutely nothing is happening.
This stuff sounds amazing. What happens if it gets into the ocean. Will it affect the wildlife
After removing the tape from the graphite you probably still have a couple of layers. Only after splitting the layer a couple of times by sticking another piece of tape to it, will it truly be one layer. Modern, more scale-able technologies use vapor deposition for neat big layers, whereas the spark plug method creates a mix of graphene platelets and nano-tubes. O wait. He got there just now ^^
heard of ferrock? really great stuff too.....
2 years on from this post and I can't find any of these possible markets that have made it
They are on their way. It's just that the supply chains are used to working with one type of technology, and suddenly comes this whole new technology which needs to be further tested, scaled up and proven before it can gain mass-adoption. Don't you worry, I'm confident we'll start to see consumer applications within the next ten years.
of course not, its just pie in the sky nonsense that never happens. it does generate Patreon and CZcams ad revenue though.
@@theamici Maybe it will happen- bit only if society and politics put pressure and /or incentives towards that direction. It is seldom or very slow that a new technology will replace an established technology as initial cost for development and machines are high and production cost will only come down with rising production scale. It is only by laws (market rules) or incentives/subsidies that can speed up developments or force them in a certain direction.
It has been about 15 years since graphene was discovered and we don't yet see it available in products. I'm reminded of the discovery of electricity and penicillin duration before the public had access. We will need those graphene dream products (water filters, electrical storage, super strong materials) very soon if they are to aid in the fight against climate change. On another note, where is the UK equivalent of USA
Senator Sheldon Whitehouse (czcams.com/users/SenatorWhitehousevideos), with his "Time To Wake Up" presentations? This guy is a real American Hero in my mind. I can't think of a single British politician worthy of such an accolade.
You have another hero in the UK. Robert Murray-Smith. Not a politician but a nice and generous scientist. Check it out... czcams.com/channels/4AkVj-qnJxNtKuz3rkq16A.html
@@smasimulationshop1028 Thank you. He's got 7 years of videos for me to catch up on. As you say, a nice guy and it looks like he explains things clearly.
Does static electricity effect graphene in any way?
The structure of graphene is not discrete (single, individual) molecules each one with only 6 carbon atoms, that's the benzene molecules... It is more like the chickenwire, where the knots are the carbon atoms. And that flat structure can contain as many atoms as we are able to grow the single layer of graphene/chickenwire.
Yes that's much better put, silly to hold up six atoms bonded like that, our chemistry teacher was the same
What you skip is that the delocalized aromatic bonds (in addition to the covalent bond you showed) which is like found in single ringed benzene, but is spread across all of the interconnected rings of an entire graphenic molecular sheet. Hopefully graphene will make solar power and battery tech economically and environmentally feasible, as our current technologies require massive amounts of toxic waste generation for cells or batteries that only last 10 to 20 years.
I just found your channel, and I'm loving your content, but some of your sound effects are a little too harsh.
THANK YOU! THIS WAS GREAT NEWS!
Hope graphene won't be like fusion, ie, "always 50 years away".
Graphene has been a thing for over 10 years. Applications for graphene and the broad range of 2D materials are still in the future.
@@CarFreeSegnitz I know it's a thing, I just want it to be MORE of a thing ;-)
Yea like @zuluknob said, it's already on the market, and final end user products are on the market.
It's still mostly on the fringes, but there are a lot of people looking hard at final end products, and there is A LOT of them, but it takes time to take things to scale and make specifications for all characteristics.
I have myself made many Kg of the stuff, various composites, oil and grease additives etc. with graphene.
Example: In motor oil usage we got 3.5% performance increase on dynamometer measured from the wheels of the vehicle.
I've seen it in golf balls . . ad
My wife is on dialysis and I heard that graphene membranes in dialysers could significantly improve dialysis ... It will be great for the patients if this happens
Are there any toxicity issues to the ecosystem with any of these new products?Is there any research on this issue? So often it seems there are unexpected negative outcomes to ill considered or hasty deployment of new compounds or technologies. Call me a ludite if you like but my experience makes me see it that way.
Great show, sounds like my Cybertruck will be made of Graphene not Stainless steel ❤️❤️❤️

Isn't filtering _everything_ out of water a bad thing? I recall that for water to be drinkable, it _has_ to have minerals and bacteria, otherwise you get distilled water (which is harmless but also quite useless to drink).
But that is the ssme problem with reverse osmosis - few minerals which you need to add or consume by other means..Destilled water is tolerable only in small quantities. If you drink too much (pure) water you desalinate which can at the end kill you...
@@tristanschreiber5279 Thank you for the clarification. That also reinforces my point that you shouldn't filter _everything_ out of the water. But I'm not sure what exactly the filter does.
I've read more about it and, yes, graphene-with-pores does filter out minerals like Calcium and Magnesium. But from what I understand, this has been the case always and we don't distinguish between salt and these useful minerals anyway? So yes, graphene is promising technology, then.
Can it be used to filter carbon dioxide from Air?
I hope not. We need CO2 in the air so our plants can breathe. If you're worried about CO2 in the air, plant trees. They do perfectly fine filtering CO2 from the air and converting it into oxygen.
The title is misleading. I hoped to learn some climate effects of graphene as the title tells me so 😒
Grow space elevators, composed of graphene from atmospheric carbon that's in the CO2, can make ozone otw?
