Can anyone explain, how, exactly, DAC stores more carbon than it uses? Even if you turn the entire SW region into solar panels to power a gigantic DAC factory, the opportunity cost of not wiring that same titanic generation into the grid vastly, vastly outscales the gains you get from burying carbon. L1 orbital mirrors, that's the ticket. Reversible, adjustable, no sloppy gas exchange problems like with the particulates.
