Biodiesel or ethanal? Tomayto or tomahto?

Figuring out the cost/benefit ratio of emerging alternative fuels has become something of a black art, but Sustainablog's Jeff McIntire-Strasburg does a pretty good quick primer for Treehugger. My take: Better to encourage all forms of bio fuel than get into finger-pointing. Gradually certain fuels will emerge as appropriate for certain markets and applications; no need to limit our potential yet.
