I think a lot of folks here really shat upon Heinburg as I remember. Interesting to hear from someone who knows him.
I recognize the reality of Peak Oil but am not going to pick a date for it. Too many variables and moving parts to get the answer within a decade or so. So why bother predicting? It'll come.
I'm also not Peak Oil Doomster person, or a POD person as I call them. I think that we can use approaches like those suggested by Amory Lovins
http://www.rmi.org/ to ensure that we don't have widepread famine or disruption due to peak oil, and that we can bridge to renewables.
But, then I'm just a petroleum engineer, so what would I know about petroleum LOL? ( Note - you've probably observed on all the discussion about peak oil tht there are many people who seem to know so much about the world's remaining hydrocarbon resources, all learned via the "alternative knowledge" section of the internet! LOL )
I've never read Heinburg; my recollection of scanning the thread is that people were essentially calling him a nazi or some such damned thing. (Note - a lot of people accuse others of that pretty easily around here. Must have seen Raiders of the Lost Ark a few too many times as children.) What was your take on that whole thing? Was he proposing a big "die off" or some such unsavory action to cure peak oil woes?
Speaking of proof reading Peak Oil books, that Matt Simmons book "Twilight in the Desert" needed a SERIOUS proof read by a geologist and a petroleum engineer. And it didn't get one and got published ridden with errors and bad assertions. That's earned it a lot of serious laughs by professionals in the field; Simmons doesn't understand the technical bits very well. He misuses the jargon to an embarrassing extent. Directionally he is correct in the form of Saudi Arabia being close to peak, but the book would have been so much better with some help from technical professionals.
