But...but...but you're confusing the pipedream (or bong-dream) with facts!
As another astute observer (who must have learned arithmetic in school, so it couldn't have been a public school) pointed out in a letter to the WSJ, to replace just the ANWAR oil with turkey poo-oil, we'd need about 35 turkeys for every living American, we'd be importing more grain than we do oil now, and the resulting product would cost more per gallon than Dom Perignon.
Otherwise, there's no reason a technologically savvy nation like the USA couldn't do it!
(We 'mericans were the first and only to put a man on the moon! Why couldn't we run our cars on $250/gal turkey-poo oil?)
