Biodiesel is a fuel derived from plants. It is an alternative fuel to standard fossil fuels, that can be made from fats and vegetable oils. It contains no petroleum or petroleum-products. If made correctly, it can be used in diesel engines with few or no modifications.
The diesel engine as we know it today was originally designed to run on mineral oil, but was able to operate on vegetable oil just as well, later Mr Diesel agreed that peanut oil was a viable alternative. The french government sponsored the peanut oil alternative at the 1900 Paris Exhibition. Vegetable oil, (essentially the original biodiesel), rather than the petroleum-based diesel fuels that tend to be used today was the fuel of choice for the engine. There was even a push to use Hemp oil; manufacturing processes were even perfected for its use before it was banned.

Yes it is safe to mix petroleum diesel and biodiesel. Blends of biodiesel and petroleum diesel are designated "BX." Where "B" states that the fuel mixture is a biodiesel blend and "X" indicates the percentage of biodiesel in the blend. For example, common blends of biodiesel in North America include B2 (2% biodiesel), B5(5%), B20(20%), and B100(100%). B100 is also know as "neat," or pure, biodiesel.
Wikipedia provides an excellent encyclopedia style article on biodiesel fuel. Other websites that offer information about biodiesel fuel are the U.S. Department of Energy's Biodiesel page and the National Biodiesel Board's page.
Yes, you can buy a hybrid that uses biodiesel but they are much harder to come by than hybrids that don't use biodiesel or biodiesel cars that aren't hybrids.
the biodiesel should be used in the diesel engine, and there are some biodiesel motorbike has been produced such BWM http://www.doinggroup.com/
Biodiesel's weight is generally 7.34 lbs/gal.
Just about any diesel vehicle will run on biodiesel.
Biodiesel
You often only find biodiesel in the Midwest or areas where corn is a big market. Biodiesel is made out of corn and that's why. Biodiesel will make your diesel engine get better gas mileage just so you know.
Biodiesel is replenishable where fossil fuels aren't. Biodiesel is made from biomass such as corn, rapeseed, sugarcane and even algae. The CO2 produced from burning biodiesel is indirectly reabsorbed by the plants that will make the next batch of biodiesel. Fossil fuels just release CO2.
See the related link to the National Biodiesel Board's - Retailer Map.Look there for a retailer in your state.When shopping for biodiesel, however, make sure that they sell biodiesel that conforms to the most recent ASTM standard.
