I sit in a hot office and think about this. I am not sure where to ask. I am genuinely curious. I have seen a breakdown of building solar panels to power the earth 2x over in order to recapture carbon equal to the rate it is being produced, but then areas of the earth that were reflective are now absorbtive of heat…

    One time, and I wasn’t even high, I was thinking we could build solar panels that power machines that pull CO2 from the atmosphere and build solid bricks of graphite that could be used to build buildings or whatever. Then I realized I had basically reinvented the tree.

      This is doable but the barrier to entry is high: a large-scale industrial carbon capture machine costs $750 million.

      Edit: graphite is used in batteries manufacturing
