I fully agree, BFRE is definitely NOT a scam. The Klann's are very honorable men! Further, their technology was proven out, as far as pilot-plant trials could show, years ago in Japan.
The only thing holding back full-size plant construction now is financing, and they have about 90% of that in place now. As I see it, their future success depends on getting that remaining 10% of financing, and my hunch is a Chinese company will do that, as their interests are high in applying this cellulosic ethanol technology to solve several needs at the same time.
