FrontierFila

I grew a bit unhappy with the name C12 Negative and felt it wasn’t such a good name after all. I’ve been doing a space game on my free time for a couple of years and had reserved the domain frontier.industries for it, so I decided to share it with the filaments and “rebrand” them FrontierFila. All new stuff about the filaments will be at http://frontier.industries/

Alumina Crucible

Based on the data from my first experiments, where the carbon fibers pruduced were around one micrometer thick and curled up, I constructed an improved experimental setup where I use Alumina crucible instead of steel one => less iron Fresh lithium carbonate instead of reusing same => less lithium oxide New cathodes with thicker layer of zinc Longer initial, low current phase Based on the inspirational article I’ve used for the experiments, both iron and …

I finally managed to do the initial carbon nanofiber experiments during July! Just to heat the empty crucible to 730°C and keep the temperature there took me 15 trial-and-error iterations. I settled on induction heating, a steel pot on rock wool and ceramic chopsticks through which a fan contraption blew air through… I even made a video out of one experiment. A friend at a research institute was helpful enough to take a couple of …

The basic idea behind C12 Negative is that there’s certain valuable materials that can be used as a carbon sink. To see if this idea works, you need to do a product lifecycle global warming potential calculation. My best estimate of the impact of consuming 1 kg of C12 Negative PLA filament is that 2.47 kg (3.27 kg if you’re dirty) CO2 equivalent emissions are released to the atmosphere. Here’s the breakdown: CO2 sequestered by …
