This excellent series three part series written by David Rotman and published in the MIT Technology Review is well worth reading if you are at all interested in biofuels. It is very US and ethanol focussed but appears to be a well balanced summary of what I’ve been reading lately.
Biodiesel doesn’t get a mention for some reason but synthetic fuels do. The series is written with an academic flavour but there are interesting snippets from scientists, entrepreneurs and a few choice words from Vinod Khosla about electric cars being toys because they will be too expensive for widespread adoption in India and China.
