Excellent job, Bob
I think biodiesels are a big step in the right direction, especially compared to the old dirty diesels. Regular diesels are getting cleaner, too (so I hear), but let's see if California ever lets them be sold in their state again. I think only the new biodiesels will be eligible.
There is plenty of room on the road (in my mind, anyway) for any vehicle where a real emphasis in reducing fuel consumption has been made. Diesels, bio-diesels, hybrids of any variety, full electrics - bring 'em on! Step by step, I say. We will not change an entire country's gluttony overnight. I'd love to see us all driving around in plug-in full electrics. Then, we just have to clean up the power grid (with more solar, hydro, wind, and nuclear power). It's going to be a long time coming, though.
