Big Difference Exists Between Biodiesel, Ethanol
By Mr Ethanol | December 10, 2007
The Free Lance-Star:
Ethanol is a distilled alcohol fuel usually made from corn or sugar cane; it’s used as a substitute for or additive to gasoline. Biodiesel is a methyl ester that’s created by breaking down a fatty acid–in other words, vegetable oil–via an organic chemistry process called transesterfication. It is used as a substitute for petroleum-based diesel fuel oil.
The proposed Tidewater plant will be making biodiesel. The raw material for biodiesel can range from straight animal fat to pure soybean or canola oil. The process for making biodiesel was invented in the mid-1800s and was used widely in South Africa before World War II.
Rudolf Diesel’s first engine (1885) was designed to run on peanut-oil fuel in addition to petroleum fuel oil. In fact, Diesel said this of vegetable-oil fuels in a 1912 speech: “The use of vegetable oils for engine fuels may seem insignificant today, but such oils may become, in the course of time, as important as petroleum and the coal-tar products of the present time.”
Most diesel engines today can run on biodiesel. Recently, Caterpillar has given the green light to biodiesel as a safe alternative to fuel its engines. Full article.

Are there comparisons available of the cost in acres needed to make bio-diesel vs ethanol.
As we move off petrol the resources needed to produce the replacement is a big question I think.

Another big difference between ethanol and biodiesel is that ethanol is one of the only approved product that can be blended with gasoline. If we are using the combustion engine for the next 50 years that is significant. Check out the free Ethanol Virtual Stock Trading program on UseCorn.com http://usecorn.com
