A couple of weeks ago the Kathleen Clay Edwards Library branch hosted an informative lecture on the use of biofuel to power personal and professional vehicles.
One of the presenters, Andrew McMahan, has provided a copy of his discussion slides so that members unable to attend can review at their convenience. He did a great job putting them together and they are a quick study guide on the topic.
They are formatted into slides in a word document so won't work well for the Slow Food web site, however, I would be happy to email them to anyone interested. Email me directly at firstname.lastname@example.org if you'd like the file. No special software is needed to view, they open in any version of Word.
