If you only consider the actual burning of bio-diesel,it's not nearly as bad as 'fossil' diesel. Cost is determined by supply and demand,just like any fuel. Diesel engines were originally designed to run on veg.oil. One of the first internal combustion engines ran on flour dust ! Bellows blew the dust into a cylinder,a spark from a static charge,timed just right,by hand,ignited it ...and boom ! A fly-wheel was turned to run machinery. A German scientist figured out that the 'Yankee Flour Engine's' secret was the oil in the flour. When the oil was sprayed into a cylinder, at the precise air mix,then highly compressed,the fuel would ignite without the need of a spark. The scientist's name was Rudolph Diesel.

Biodiesel is a better choice than ethanol in gasoline.
We can grow the soy beans for oil without losing any food farm land. Biodiesel is efficient to make.
It is as efficient as crude diesel, which gasahol is not as efficient as gasoline. Ethanol is not efficient to make.
It could be made affordable.
Some problems are that it ha more lubricity and can make rubber gaskets leak. It also is a cleaner and cleans tanks and lines so that filters get filled very quickly and must be changed several times before things run smoothly.

There is no real environmental impact of biodiesel. When you make the diesel your bye product is glycerin. The glycerin is what they use to make soap.
I am not sure of the cost of biodiesel but i know the machines to make it cost about 3,000. I had a boss who would sell the machines and use the diesel in his truck and farm equipment.

Bio-diesel is called a zero carbon fuel, but its not! Burning bio-diesel emits carbon dioxide and carbon monoxide. But no more than the plant absorbed from which it was made. so they call it zero carbon.
Bio-diesel is a cleaner fuel due to less impurities in the fuel
you will use 10% more fuel than diesel #2
it costs about 12-14% more than diesel
large scale use of bio-fuel may lead to further de-forrestation

It will produce pollutants very similar to diesel oil.
