Wow. That’s amazing. What are you hoping for? Something you can use to dox people?

You are out of your mind. And when you say “you have no skin in the game” you don’t know what that means.

Read the book. Write Bessel love letters. Start a subreddit for Bessel stans. Good lord.

individual action was conceived by the plastic industry.

Perhaps. I've grown tired of every revolutionary technology disappearing because it's too expensive, material intense, or impractical. I tend to forget that yes, some do, in fact, make it into production devices.

Finally!

My idea for manufactured arctic land masses could be feasible! (Would have to be considered international land and nature reserve to avoid property grabs)

My crack sci fi idea: If we can create a non-reactive carbon material that can be used as a skeleton lattice we could encourage ice growth in the coldest regions of the sea and create more white reflective surfaces to bounce off heat radiation from the atmosphere - dampening the heat transfer and potentially delaying warming.

Probably a terrible idea, but this is the first applied science that lends itself to the idea!

This is a cool paper, but it’s title is somewhat misleading. The process they use does create carbon nanotubes (CNT), but it creates them in a very messy mixture of other nano-structured carbon. Their material surpasses other CNT production methods because most CNT researchers aren’t looking for physical properties like tensile strength. CNTs do have really good physical properties in polymer composites, but that’s a pretty underwhelming application for them. The article here even lists applications for CNTs that do not apply to this mixture, which is pretty misleading.

The layman’s TLDR for this paper is “we found that if you process waste plastic in this way, you can reinforce other plastic with it to make it even stronger.”

Or, by the time it gets where it's going it's become normal and doesn't feel as special.
