I have read a bit about this guy, and as well as his one credible book Saharasia. I know he is an avid follower of Reich, and he wrote Saharasia as a means of "proving" Reichs Sex-Economic theory.
He is a pseudo-scientist of the first order, still selling the ridiculous orgone idea to those still in the dark enough to believe it.
He has an entire page on his site dedicated to debunking the critics of his work, yet provides no explanation as to how orgone exists or works....
Saharasia was ok, so long as you are prepared to sit through 400+ pages of methodically backed up text whose only purpose is to prove that before 4000bce there was no violence, and that it wasn't until after the aridization of the Sahara region that violence emerged.....he wrote the book as a dissertation from the U of Kansas geography dept.
