There's a Scientific American article about the use of coffee as alternative
fuel. "Even after being subjected to the rigors of brewing, roughly 15
percent of the weight of dried coffee grounds is oil, which, much like palm
and soybean oil, can be converted into biodiesel."
I found this interesting too: "The researchers note that coffee's high
proportion of antioxidants, such as chlorogenic acid, acts as a natural
preservative for the resulting biodiesel, preventing it from going bad ..."
These same antioxidants don't protect coffee's flavor? I guess that "bad"
for biodiesel isn't the same as "bad" for drinking coffee.
