I have written on so many aspects you can fill most gaps with stuff I have already done at least once.
Sources are Megascale engineering, and my Future Tech/trivial nanotechnology columns in Cryonics magazine over something like 1989 to 1992 or so. It if is too much trouble for you to find them, I could copy the lot of them out of the magazine archive.
Pick something out of that and I can update it, or if you want I can do something new on some theme of your choice.
