Comment on Half a pound of this powder can remove as much CO2 from the air as a treeparentComments−floxy1yhow you would sequester the gaseous CO2 other than "put it underground."I wonder if there is a reason you couldn't just sequester the powder. Probably too expensive? Or not volume efficient?to leak out eventually due to plate techtonicsThis might seem shortsighted, but I'm OK pushing the problem out by 50 million years or so.−BizarroLand1ySince the powder is reusable, it likely wouldn't make sense to sequester it with the CO2 either materially or financially.−entropicdrifter1yThis. The powder is more efficiently used as a way to move the CO2 around than as a means to keep it sequestered.−Woodi1yStill, tree produce oxygen from that CO_2. And do not need energy from grid for that :)Threating CO_2 like radioactive waste, putting it underground etc - that what I call not self-sustained :>

This. The powder is more efficiently used as a way to move the CO2 around than as a means to keep it sequestered.
