You obviously see no value in land, as vertical tubes making use of vertical space above the land, increase reactor density per square foot of land which increases the per acre cost of the PBR. Clever way for DF to claim his system is cheaper per acre to build, which it probably is, but its productivity per acre would lower, thus hood winking investors with his mine is cheaper to build nonsense.

Vertical tubes don't need the pig, they use turbulence and gas bubbles (Archimedes' principle) to do the scrubbing, and there is nothing new or novel about PIGs, except maybe the lipstick they use, LOL.

I would kike to learn more about vertical vs horizontal tubes.I was led to believe that our closed system requires less land space than open systems. Now I am being told that vertical systems have been developed. This means much,much less land space.The question then is about the relative productivity of those systems.
