Thanks for the list of suggestions, David Tanzer. I'm sorry to take so long to reply to them.
(Sorry for the full name, but even "David T." is ambiguous!)
I've been taking a long time to reply because I'm rather intimidated by the Laura and John Arnold Foundation's email; I really am used to working within lots of constraints, and doing research that I and a few colleagues and grad students can do. When you say things like
> Create a major public works program for R & D in biospherics and sustainable development.
I think "that's way beyond my competence level!" But maybe I should relax and just contact them and see what if anything comes of it.
