I don’t understand your objection. You have X million tons of carbon sequestered in Y million cubic feet of substrate. If the substrate is seaweed instead of lumber, you lose Y/5 from Y each year, instead of losing Y/100 from Y each year. That just means you need to produce Y/5 cubic feet per year instead of Y/100 cubic feet per year. It doesn’t affect X. Is it easier to produce Y/5 cubic feet of seaweed than Y/100 cubic feet of lumber? The whole point of this project is to find out.
