Everything else I have seen has skipped over the chemical properties of the covalent bonds, much less explained them in such simple and straightforward ways. While other sources usually do discuss the engineering challenges in creating nanotubes, not one has gone into such depth much less had actual visuals and footage!

    I’ve studied just a few of the physics involved in carbon nanotubes recently at university and believe me, this video did a great job at saving you from many headaches and explaining all you really need to know about them. The only thing I would’ve added in here is the research involving the addition of impurities or holes in the nanotube structure, and the multi layer nanotubes, which show quite promising results. Some configurations even have superconducting capabilities, and it is believed we might be able to get a close-to-room temp superconductor with them, but as far as I know none of that has been confirmed yet. What’s coolest about it is how depending on the way you connect the carbon layers, you can get very different material properties.

    Pssst. Don't say that. We don't like to use the bad A-word! I already worked with that stuff around 12 years ago. I did the mandatory practical semester of my material science studies in a research institute and was really psyched about working with CNTs. But that stuff is *mean*. I do agree with Real Engineering that the chemistry and material science of this stuff is amazing. But the physics of it cannot be ignored: CNTs are very small and can be inhaled and AFAIK there's the possibility that it will cause cancer (which is a statistically risk just as it is with X-rays). Also they stick together and it's hard to separate those short strands once you put them in a (small) container to ship them. So unless you can make them really long you would need to process them where you produce them. And then there's the problem of the really bad wettability of carbon whether it's molten metals or anorganic solutions, e.g for electrochemical processes. It's a huge pain in the behind. BTW: The risk of inhaling and causing damage is also something that is true of carbon fibres, especially of they break during testing or a crash. We looked into that a few years ago and there weren't that many studies about it. But now a short googling of "respirable carbon fiber" produced a meta-study with lots of citations on the toxicity of CF, CNT and asbestos on pulmonary cells: www.ncbi.nlm.nih.gov/pmc/articles/PMC5319145/ And it's not really a reassuring read...

    And that's why I hope CNT won't ever take off. Kind of a shame, but it's for the best. Much like Carbon nano tubes, Asbestos was the wonder material of its day. Yet it got more and more widely used even as evidence mounted as to how dangerous it is. Mostly just because it was cheap. We made the mistake of using that material in everything, and hundreds of thousands paid and are still paying the ultimate price for it. It's still everywhere. That's something that must not be allowed to happen again.

Once they can be pure graphene, batteries will reach an entirely new level. Phone batteries of current size would last a week. Or OEM's will be able to have the same mAh as currently used In a battery smaller than a postage stamp. Hopefully these come quick enough (mass production) to save to planet! Nano T's since '91.

Albert Einstein said nuclear energy is not possible, at that time neutrons were not discovered yet and afterwards everything changes when quantum mechanical model comes. Same with fusion. Once you solve one problem ten more problems will arise. There is no way to predict how many problems will arise even before you solve existing ones.

Or the fact that the internal combustion engine took 250 years to produce feasable transportation (first working ICE was invented in the 1600s and could barely carry itself up a super shallow slope). And powered flight? It took all the way from the beginning of human imagination to the 1900s for us to succeed in doing that.

You sometimes show long lengths of black twine rolling onto spools while talking about nanotubes, though from the information you provide I assume these shots cannot be of nanotubes because they are longer than what is currently possible. I assume you are using footage of other materials to illustrate what advanced nanotube technology might look like in the future. This makes sense, but it might be helpful for easily confused viewers like myself if you included a small annotation in the corner of the screen describing what the video content is actually depicting. There are a few shots where I'm not sure if I'm looking at actual nanotubes or not.

    CNTs can be manufactured with extremely high consistency, so that is a non-issue in my experience. Impurities are the results of the catalysts that are required to synthesize the nanotubes (cobalt, moly, aluminum). Those elements can be removed chemically with acids or thermally. Thermal purification can be highly effective at removing the impurities but care must be taken as the structure of the tubes can suffer damage if the heat is excessive.
