I can't believe the thermodynamic ignorance out there. How many calories of fossil fuels energy does it take to produce one calorie's worth of rendered animal fat any way -- 50? 100? even more?

$this->bbcode_second_pass_quote('', 'T')ULSA, Okla. -- Here in the heart of the oil patch, laboratory technician Christine King is surrounded these days by containers of what her employer hopes will become the next big thing in energy: grease and fat.
There's used cooking oil, in various shades of yellow. There's chicken fat, a dark-brown goo with a scent that evokes dog food. "Here's one that smells really bad," Ms. King says, reaching for a jar and opening the lid. Inside: taco-and-pizza grease.
The small lab is in an industrial building that serves as the headquarters of Syntroleum Corp. For two decades, the people behind the tiny company have tried in vain to turn a profit by making liquid transportation fuel out of natural gas. Last summer, frustrated by its lack of progress reinventing fossil fuel, Syntroleum began shifting to what it saw as a greener pasture: making fuel from the renewable resource known as fat.
