This nanotube chem factory thing

We need to mass produce metalic calalysts trapped in buckyballs. Produce these in a separate continuous process, then shoot them into energized substrate. Print the lattice you want, the arrangement of calalytic converters. Then jam inthe input and output ports, short nanotube chains, to feed the thing. Put it in floating water, under the sun.

But, getting the catalytic converters, take a large diameter nanotube, stuff in the metal atom and seal both ends. See, I think this works out.

Take two sheets of this, one sheet a semipermeable H@0 and CO2 admitter (in proper proportion), and the top sheet are alcohol chem generators. Then fill it with air, and use heat to move inputs to the top and output gas is alcohol.
My solar fuel predictions:
Algenol has the right current approach and likely to get 5% solar efficiency. The approach above should approach 20% efficiency. Yes, solar efficiency in these rages make an industry.
