Think this one out. One 60# bushel of soy yields ~1+ gallons of cold pressed oil (11#s when solvent extracted). It also yields ~45#s of 48% high protein feed meal. Place the one gallon of biodiesel in the tank of a high fuel economy diesel passenger car. Place the 45#s of meal in the passenger's seat. Assume that your only food source for one day is the feed meal. Start the car and proceed down the road. See which runs out first. Had the trip been 500 miles, the fuel economy of the car been 50 mpg, you would have been the impetus for amassing 450#s of food, yet only consuming perhaps 1. Herein lies the biggest concern relative to biodiesel - a feed meal glut - thereby bringing offerings for oil bearing commodities down. The farming community needs to bring every oil bearing seed possible into play to regulate the feed meal production or else more farmers will succcumb to bankruptcy when the backlash of a glut hits. Sorry, but it's a reality. Perhaps now some will see why high oil / low meal yielding crops like hemp must be brought into the market - to reduce feed meal supply relative to oil production. It's not a "hippie vs conservative" thing. It's a survival thing.
