Originally posted by john galt: Nearly all of the biofuels problems relate to ethanol not biodiesel. The myoptic media likes to lump them together for their dumbed-down audience.
At the farmstead scale, Fuelfarmer has shown biodiesel can be successfully done in Virginia with a small percent of cropland, comparable to what one would set aside for feeding draft animals traditionally.
Big oilcrop producers find they can get a high value food oil product and biodiesel can be made from the 'waste' and substandard crop percent.
It's not feasible to replace any significant portion of the diesel fuel market with biodiesel, however enough can be produced to be used as a fuel additive for all petro-diesel to make it burn cleaner and reduce toxic pollution
And the one item that NEVER accompanies any discussion on "biofuels" as relating to biodiesel is that the glycerine layer from the biodiesel production has been proven to be a viable (and much cheaper) source for ethanol production, closing the gap and freeing up land otherwise used for crops. But the media, bought and paid for, just keeps on harping on the negative side of ethanol and biofuels in general. When making comparisons, in the interests of fairness, the whole picture must be given, not just cherry picked portions.
This tutorial has it's roots in the collaborative biodiesel tutorial. When that that tutorial stopped being maintained, the content was the starting place for this tutorial. Content from the Infopop Biodiesel & SVO Discussion Forums and the Vegetable Oil Diesel Forum was used to expand the tutorial along with my personal experiences.
In an effort to remember the roots of the tutorial, I would like to invite you to help out with the tutorial as others have before you. Your suggestions, comments, and yes even articles are always welcome.
