While I'm trying to get the amount of hand-waving in the "Irregularity" essay down to sane levels (I don't want to pick on other people for making vague, unsupported statements and then make a hypocrite of myself), I am also thinking about what to write about next.
There are at least three mega-engineering concepts I've been noodling about. Parapundit touched on one (aerosols) the other day; the other two are orbital sunshades and ultra-large convection towers. I'm not sure how much time it would take to finish a treatment of any of these, but given a choice, what would you like to see?
