XRpredator said:I think biodiesel was a noble idea, but it takes more fuel to make it than you get out of it (when you go all the way down the production line)
You're both correct to some extent. It takes very little energy to convert corn into biodiesel. However when you factor in the energy consumed to plow the field, plant, harvest and transport the corn to processing consumption can quickly outweigh production.MrLuckey said:Negative, we do a lot of process controls for a couple bio-diesel companies and that's just not true.
Yes, Ed, I was factoring the growing/harvesting of the biomass as well . . . I agree with you that the actual manufacture is relatively cheap.WoodsRider said:You're both correct to some extent.

yeah, but then you gotta factor that into the manufacturing of the biodiesel . . . at least until we have enough of a stock of biodiesel to make things work . . . right?Patman said:So is the amount of energy to locate, drill, pump, transport, refine, and transport crude to the retail outlet take less energy?
http://e85.whipnet.net/alt.fuel/animal.fat.htmla plant is being built in the USA, with the intent of producing 11.4 million litres (3 million gallons) biodiesel from some of the estimated 1 billion kg (2.2 billion pounds) of chicken fat
