    I meant how nanotubes were presented like they were going to change the world. There was even talk of being able to build a space elevator with them. Maybe once there’s a permanent Moon base they will be able to take advantage of the graphene, but as you point out it could be decades into the future.

      Those things are still all possible, and carbon nanotubes have already changed the world with their applications on a macro scale.

      The point I was making is more that they are still in their infancy as a technological innovation and product, and it might need years if not decades more to be widely adopted into widespread use and be world changing for individual people.

        carbon nanotubes have already changed the world with their applications on a macro scale.

        I’m not disagreeing or disparaging what you say, but I’d love to hear some examples.

          Their conductive properties and light weight makes them perfect for use in large scale battery components.

          They have revolutionized polymer composites, as nanotubes bond very well to epoxy and create a material significantly stronger other current composite materials. The listed current applications for this are wind turbines, marine paints on ships, professional sports equipment such as skis, hockey skates, arrows, etc.

          Vantablack is made from nanotubes.

          I had to look this up, but apparently they are used in atomic force microscopes and have allowed us to discover tens of thousands of microbiological species that were undetected before along with revolutionized microbiological studies.

          It’s a significantly lighter lightweight adhesive compared to glue and other tapes. Since the tape also uses Van der Waals forces, there are no chemical adhesives needed.

          This is a limited list of course, but there are many further niches uses in various fields of research.

            wind turbines,

            Wind turbines are bad: they kill birds, the sounds mess with marine animals, and there’s no way to recycle the blades so they have to be buried underground.

            marine paints on ships, professional sports equipment such as skis, hockey skates, arrows, etc.

            These things existed before nanotubes, marginal improvement isn’t world-changing.

            Vantablack

            Rich people stuff.

            there are many further niches uses

            But that’s it: niche uses that don’t really affect people’s lives, so carbon nanotubes haven’t changed the world on a macro scale. We’re just not there yet as a society/species and we won’t be as long as there are hungry and homeless people on this planet.

              Wind turbines are remarkable as wind power though, and the fossil fuel industry exaggerates the still unfortunate number of birds killed by them.

                  I guess China is installing so many wind turbines because they’re filthy capitalists, right?

                  What “fossil fuel” interests does China have to be the leader in installing wind turbines?

                    What kind of argument is that? lmao. The US is also installing wind turbines, they are based communists!

                    I could be wrong about fossil fuel industry supporting wind turbines, but you can’t make the argument that just because China does something that means that thing is automatically good.

                    The WEF is all gung-ho for wind power: https://www.weforum.org/agenda/2023/05/greenertower-greener-steel-wind-power/

                    I guess the WEF is a bunch of communists and we should do everything they say.

                    Wind turbines are dumb and worse than nuclear power, I don’t care if Lenin himself rises from the dead and says wind power is the most communist thing ever.

                  China is a big advocate of wind power.

                  Relying on any one method though is stupid, a combination is needed.

                    So? So is the US, Scotland, Denmark… what does that have to do with wind turbines being bad for the environment, impossible to recycle and less efficient than the alternative (nuclear)?
