https://archive.is/bl4XZ https://archive.is/bl4XZ It's too bad these DAC systems don't take it a step further kicking the o2 back into the atmosphere while turning the carbon into something physical and industrially valuable like say spools of carbon fiber fabric or graphene/carbon nanotubes.

This is off topic, but does anyone else always get an infinitely reloading captcha for archive[.]is links?

  That happens if you use Cloudflare as DNS. archive.is has a notorious feud with Cloudflare over some technical detail they care about strongly.

  At this point every thread with an archive.is link has atleast one similar comment. Etiquette should probably shift to including this info in the same comment that posts the link to reduce the noise.

Those are called "trees" and were actively killing them to create farm land to feed an ever growing population.

  Have you considered that taking out CO2 from the air will also kill trees and other plant life? CO2 is their air to breath. But of course, let's trust corporations and government to carefully calculate exactly how much CO2 they should take out. Can't wait for the revival of the ice age scare from the 80s...

    Taking out too much co2 won't be a problem until it turns massively profitable.

  But are trees the most efficient technology for the job? Trees evolved to work with the inputs of their environment, we can engineer practically anything in terms of what materials/inputs are available to a synthetic tree having the sole purpose of spitting out solid carbon. It's non-trivial to prevent other nations from destroying their forests. But nations that care might be able to make up for it with engineering, from anywhere else on the planet, at least in terms of atmospheric co2. Is the best way for such a nation to do so to just plant trees, or can we do better? It seems like a path worth at least exploring the possibilities of.

Oxygen really likes being connected carbon so spitting it off takes a lot of energy. All the things you mentioned burn in oxygen for exactly that reason. Making them requires at least as much energy as you’d get back by burning them so is hard to justify right now when instead you could make it directly from the carbon in things like fossil fuels and not have to spend all the energy to spit oxygen off first

  Maybe the DAC system can be put at the center of a giant heliostat for the required energy to split the C from the O2... https://en.wikipedia.org/wiki/File:Font_Romeu_France.jpg https://en.wikipedia.org/wiki/File:Font_Romeu_France.jpg

    I guess that's something humanity can consider once the question of energy sources is settled. For now, whatever energy that could be used to gather energy to split CO2 into C and O2 could as well be used to replace fossil-burning generators, at likely better efficiency.
