Commercializing a process tech is tough business. It's a game of leap frog and your window of opportunity is small and unpredictable. The biodiesel process biz is full of mouse traps, that's for sure. I lost big on it, cost me my biz, house, wife, dogs, etc. It's full of bs artists, dreamers, liars, opportunists, etc. I am doing well in the good ol' tank business and will likely not be jumping back in to biodiesel. I do believe it will replace diesel eventually as the economics are driving it that way, peak oil, economies of scale, third world feedstock, algae, etc. I hope for my kids sake it does. 78% of air born cancer causing toxins come from diesel.
