I emailed the researchers to clarify a detail that was unclear from the paper to verify the "cost-effective" claim of the title here, but if it is true, this is as big a jump beyond the top of the line carbon fibers today as those fibers are from the original carbon fibers of the 1970s. 🤯

Simultaneous large jump in strength (how hard you can pull before it breaks) and stiffness (how much it deforms when you pull it), when usually they have an inverse relationship!

Most of the time when you see CNTs (or anything "nano") in the news, it is total junk from a real world practical perspective for a number of reasons (you say "nano", I more or less hear "blockchain" 😂). This could be different. Fingers crossed. I will update when I get a reply from the authors.

There are two ways it could be read... and it may actually cost $10k+ per pound, which is not all that useful immediately, though still interesting.
