title should read "makes plastic from CO², H²O,electrons,and half of the expensive end of the periodic table" catalitic reactions are well know, and I think that in a lot of related processes are actualy things that are problematic and engineers work hard to avoid, IE: large scale industrial processes useing CO², plus other gasses will be plagued with "byproducts" or "deposits"that gum stuff up and are tedious to remove, and those will be solids and liquids that are oils and polymers. Peversly, "clean" CO² can sometimes get wildly expensive, CO² is used in food, and medical, and other refining, and for those purposes, regular industrial CO² wont do, and we are back to square one, and the nitty gritty of chemical engineering. One interesting use for CO² is as a solvent, as it causes no chemical changes itself, that it must be in a supper critical state adds a bit of challenge, but the end products are ultra pure.
