Reply to comment by Herbert-Quain in Scientists create carbon nanotubes out of plastic waste using an energy-efficient, low-cost, low-emissions process. Compared to commercial methods for carbon nanotube production that are being used right now, ours uses about 90% less energy and generates 90%-94% less carbon dioxide by Wagamaga
It’s not like nanotubes need to be made in 1000 gallon cauldrons. I would think we would need far less material than raw/smelted steel. So it could be made in a kiln or something. Honestly though the amount of heat needed is not a hurdle in scaling this up.
Really manually intensive /precise processes like making a sheet of graphene have soooo many more barriers to scaling than simply “apply more heat”
