Deffeyes is giving a talk at CalTech.  That's where David Goodstein, author of "Out of Gas: the End of the Age of Oil" works. He's not just a physics professor there, he's the vice-provost.

I think it would be great if Goodstein and Deffeyes got together. Their areas of expertise complement each other. The weakness in Deffeyes' books is that he doesn't get into the thermodynamics of alternatives enough, while Goodstein is all about thermodynamics.

I'm a Caltech alum myself, and my son just graduated from there this past June. At the commencement address, the school president, David Baltimore, mentioned Peak Oil as a challenge which the school's engineering and science graduates would have to take on during their careers. So I think they are pretty big into the whole Peak Oil scenario around there. David Goodstein does have a favorable blurb about Deffeyes' book on the web page:

"With his folksy style and penetrating vision, Deffeyes tells it like it is. This book is another nail in the coffin of the age of oil."
   --David Goodstein,
       Vice Provost, California Institute of Technology,
       and author of Out of Gas: The End of the Age of Oil

I live a ways from Caltech now but I'll see if I can drive down and attending this talk.

The irony of the situation for someone who believes in PO is beyond me.
