Re:Economical? Brilliant (Score 1)

I must nod in deference to thermodynamics as I point out that a primary energy source is being forgotten: the animal feed. Sure, use turkey guts or sewage or whatever, but you're ultimately harnessing solar energy through photosynthesis. Turkeys eat (I presume) grain of some sort as part of their feed. The hydrocarbons (err, carbohydrates) that make up much of their offal came about through photosynthesis, whereby the polymer chains were elongated and molecular bonds formed. This process just breaks those bonds down into a more readily ignitable compound: oil. The sun already did the heavy lifting (and pulled carbon out of the air to do it). No energy is created in this process; molecules are re-arranged such that they will more readily release the energy already stored therein. An absoultely brilliant solution, in my book. I could be wrong.
