Jesus, is this for real? It raises so many questions.
--How do you make biodiesel out of human fat?
--What quantity of human fat would you need to actually fuel a car? For that matter, what quantity of fat is usually removed from procedures like liposuction?
--Did this guy like, plan this for a long time and carefully store his patients' fat for the purpose?
--In his fridge, or what? I mean, this guy would have had to walk out of his clinic with one of those little biohazard coolers full of human fat. Over and over again. (Unless he was smuggling baggies it in his pockets or something.)
--Plus, because "the vast majority of [his patients]" actually want their fat to be used for fuel, according to him... did he ask them that beforehand? "I want to power my hybrid car, do you mind?" I wouldn't mind. I mean, it's just going to waste otherwise, right?
--What kind of byproducts result from refining human fat for biodiesel? I picture some kind of gross sludge. But hey, maybe that's the case for corn biodiesel.
--What kind of byproducts result from burning "lipodiesel"? Does it smell disgusting?
--"California law forbids the use of human medical waste to power vehicles," according to the article. Is this a specific law which was already on the books, possibly as a result of some other biomedical debacle, or is it just a more particular extension of some "you can't do anything with human medical waste except burn it" law?
Speculations and insights welcome. :D
