For a sort of "glossy outline" on Gates and a couple of others:

GLOBAL PHILANTHROPY
The World's Conscience
By Rüdiger Falksohn

The best info I've seen on some of the Gates Foundation projects is unfortunately at "membership sites." (It is mostly "medical technology," with just a little politics tossed in.)

I'll take a look at whether I can sort out some of the "more accessible" stuff, if it's of interest. Let me know here or by PM if you want more to look at and can't find it on your own.

Note: It's not that I keep special track of billionares, but I do keep some notes on just about anybody I notice who could screw us, might screw us, has screwed us, or is big enough to influence the ones who do. It's sort of a hobby.
