My master's research was actually in carbon nanotubes and I still learned stuff from this video. Thanks for the knowledge and enthusiasm

[thorvaldspear]

That atom-by-atom nanotube construction animation is really cool!

[RchardH]

The older I get the less I trust thinner than a human hair, mines getting pretty friggin thin.

Would love to see an update to this in 2021. A yearly update would actually be really good because then it can be a record of positive progress. Goodness knows we need more optimism in this world.

Couple of comments as someone who did research in the field... 1)"As it turns out carbon nanotubes can be easily mass produced already." This is true only by technicality. Yes, they can be mass produced, but not really in the desired forms that are useful (yet). You mentioned chirality and semiconducting vs metallic but, as far as I know, it is still extremely difficult (and/or expensive) to selectively grow specific chiralities. The same for of the other major factors determining properties such as length and number of walls. 2) I cringe every time anyone brings up the space elevator. It's not feasible/impossible on so many different levels and has done more harm to the development of nanotechnology (as you mentioned by setting expectations so high) than good. It was a terrible back of the envelope calculation that extrapolated nanoscale properties to macroscale structures. This is a big problem with reporting (and sometimes even research) in the community. Properties of carbon nanotubes, graphene, etc. are so "amazing" BECAUSE they are small, it has everything to do with scale. Once you have 10 layers of "graphene" stacked, it is no longer graphene, it's thin graphite. Properties of bundles of nanotubes are very different than those of individual tubes. This is why the only serious applications (in the near term, if not ever) are for devices that intrinsically operate at the micro/nano scale, such as solar cells, supercapacitors, and SOME instances of composite materials.

Love this. Another one knocked out the park! Great stuff.

[DanaVastman]

I do appreciate your lucid content! Not repetitive like much of my follows. Often learn awesome new stuff which is my passion...

[ksharmakartik]

Everything is a game changer until realised...

[diacoder]

You are always so well researched and edit very well.

[jakeydog]

Matt first time I have seen you. In your brilliantly and concise explanation of carbon nanotubes you have reignited my love for science... Thank You. 👍👍 liked and Subscribed

[MatrixJockey]

I appreciate this video on Carbon Nanotubes. I have been following the breakthroughs of the material over the years, but that seemingly has died down a bit.

[nommindymple]

"... because water vapor is everywhere ..." ( 7:43 ) . Looks at my current 2% humidity level here in Las Vegas.

[lghammer]

Fantastic video! That's so awesome to see such a widespread application of Carbon Nanotubes, the way they increase Solar Panel efficiency's really cool !

[joopvanroy]

If and when these panels that transform heat into light (wtf!?) hit the market at scale... holy moly we're in for a huge paradigm shift. So exciting!

[michaelfelder]

More on the "why' this tech is not everywhere please.

[GGnext.crazycro]

This gets me so excited for future tech

[andrewburney]

There use in fuel cells as a catalyst support is very useful. They can be used in hydrogen storage as well

[garrygballard]

I'd like to see a video like this on Perovskite and an update on where research is.

[RyanWilliams]

Okay, I want my electric car covered in heat + solar panels now, please.

[zatar]

5:13 while it would look awesome You really Don't want to paint your car with it.
All that light it traps turns into HEAT.
Great for passive solar gain applications; But it would basically be turning you car into a solar oven.
