Imagine that you dedicate your Research into producing a single layer of cells, that divides a cilindrical glass recipient in two volumes.

May be this can be done by modifying an existing multicellular organism that displays thin profile. I really don't know for sure, out of my element here. It shouldn't be a problem that the organism has a some cell layers, simply that it is thin. What is really important is that he divides the container.

Assuming you do this, you start modifying this organism, genetically, so that it can take chemicals from one side of the cilinder and secrete them on the other side, after metabolism. 

This could, in principle, be used as a general biomanufacturing technique to produce chemicals, drugs, as well as to process waste. Could it be also used for carbon capture?
