Arthur T Knackerbracket has found the following story:

Researchers have used liquid metals to turn carbon dioxide back into solid coal, in a world-first breakthrough that could transform our approach to carbon capture and storage.

The research team led by RMIT University in Melbourne, Australia, have developed a new technique that can efficiently convert CO2 from a gas into solid particles of carbon.

Published in the journal Nature Communications, the research offers an alternative pathway for safely and permanently removing the greenhouse gas from our atmosphere.

Current technologies for carbon capture and storage focus on compressing CO2 into a liquid form, transporting it to a suitable site and injecting it underground.

    why does it matter? stick it in a desert next to huge solar panels, and you can then just let the wind disperse the carbon flakes (from what I see the end result is not dangerous except for some embedded CO, but I assume that gets fixed within some reasonable amount of time by the atmosphere). would that be any problem at all?

    You would have to cover the entire Sahara Desert in solar panels to produce enough energy to make any kind of meaningful difference. The world production of solar panels is woefully incapable of doing that, and solar panels are better used elsewhere.

    I think there are some miners with black lung that want to talk about your benign carbon flake dispersal.

      If the carbon flakes are large enough, that ceases to be a problem.
