here, let me grab the soab box for a minute.
i like the you burn it you refine it idea.
my personal feelings are this. if the black gewww is so scarce, lets just suck it all up, make that gurgling sound as ya finishing the shake, and move the @$#$ along with something new.
this whole oil thing reminds me of a line from a movie with george c scott. when told to blame the problem on the arabs, he replied "boy, we are the arabs"
i'm sure as time goes along, someone here will find a way to burn something else in our beloved machines.
we'll pool together our resourses and be the next "new money"
