The question I never see asked is, just how much of this "biodiesel" oil is available? IOW, suppose we get a million vehicles running exclusively on it, is the supply there realistically? Will there be long lines at MacDonalds instead of the Mobil station? Just kidding on that.
Seriously, providing veggie oil in these kinds of quantities is a completely different animal than a few thousand cars hitting restaurants for their leftovers.

I am not an expert on providing you an exact number but vegetable oil is just that, it is compressed organic matter. The earth has plenty of land to grow 1000X the amount of vegetables we are growing now so it's seems unlimited. However, from my understanding, the real issue is having a good supply of other energy to convert corn/sugar to ethenol and processing the organic matter into veggie oil. The easy answer is nuclear energy.
The radical environmental protection movement that began in the late 60's and into the 70's really squashed our ability to pursue nuclear power to it's full potential. But even some of the hold-overs from that era are starting to realize that this is a better option for the environment then burning fossil fuel for the next 50 years. Also, the technology is much safer then it was 30 years ago.
