Sought this book out after reading Naam's fiction. This is an optimists survey of the state of the human ecosystem. Some very good ideas in here for managing the planet and your local politics also.

I am not scientist enough to say whether these ideas will work or not, but our author has some good friends who are. It is about time we do something about solar power, one way or another.

Really interesting to read about the collective intelligence. I think political climate has to factor in also - lots of people in a repressive China basically stagnated in technology - but these ideas are pretty cool. In his fiction books, the "groupthink" is taken to an extreme. Will be interesting to see what the third book of the series does with this.
