Direct conversion of CO2 to solid carbon by Gallium-based liquid metals
If this paper is not fraudulent, this could be the tipping point against climate change.Gallium is cheap (~$300/kg), abundant (by product of Aluminum mining).This process runs at 200C and 1 Bar (=0.98 ATM).Temperature can be concentrated via greenhouses/mirrors to 200C with 0 carbon by-products, 0 advances in battery tech, 0 advances in solar tech.We could start pulling more CO2 out of the atmosphere than we put in, and at that point we'd be pretty confident things won't get worse for the climate.I'm sure there's a negative view of this and something too easy that I'm missing. But right now I'm very excited.
