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.<p>Gallium is cheap (~$300/kg), abundant (by product of Aluminum mining).<p>This process runs at 200C and 1 Bar (=0.98 ATM).<p>Temperature can be concentrated via greenhouses/mirrors to 200C with 0 carbon by-products, 0 advances in battery tech, 0 advances in solar tech.<p>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.<p>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.
