So like… grow switch grass, harvest it and burn it to harvest the flu gas co2?

Idk if you burn it. Digest it, maybe, into a fuel or whatnot. My point is biomass is a more-familiar industrial input than whatever comes out of direct-air capture .

co2 is pretty valuable as feedstock. If you burn it , you can recover the potassium and phosphorus to reseed the next batch.

Well once you have the grass you could just ferment it into ethanol... An option that has been available to us this entire time...

That works for things like E85, but does not for airplane fuel or diesel or natural gas or...

The density of ethanol is the issue, no?
