Here's some recent news about another biodiesel fuel source, algae. http://tinyurl.com/25z6pq
I've also heard mention of a plant/tree from India, Jatrophra, that has a good potential. Granted, these are meant for diesel engines, but that's something.
Regarding oink's point about the cycling of CO2 with biodiesel fuels, this is what I've read also. It's not the same as releasing gases from fossil fuels which had been taken out of our environment a long time ago. There is an issue with how the biodiesel plants are powered. It would be great (I think) if they are powered by their own fuel, or supplemented heavily by solar and wind.
And speaking of releasing CO and CO2 from fossil fuels, when I led a birding trip in Alaska a few years ago, a researcher presented to our group about his work: monitoring greenhouse gases released from the melting permafrost. These are gases that were frozen into the ground many years ago. This dynamic of the general warming trend is believed to be adding to the acceleration of global warming.
