Reply to comment by MatrioticMuckraker in Researchers unveil the least costly carbon capture system to date - down to $39 per metric ton. by PNNL

There are species of seaweed that can grow up to 2m in a day. Pulling CO2 from the oceans might be a better long term strategy than pulling CO2 from the atmosphere (since oceanic CO2 comes from the atmosphere), since it's more heavily concentrated. Atmospheric CO2 capture sounds great until you realize that putting it on a smokestack is just inherently better, at which point it just becomes CCS.
