New Hampshire biodiesel class for farmers

I'm teaching a biodiesel workshop in Lee, New Hampshire- somewhat near Dover and Portsmouth, NH. This class isn't just for farmers- everything in the class will also apply to homebrewers from other settings- but we have a strong focus on farm applications for biodiesel production since the host facility is so involved in farm-scale biodiesel research and has done research in growing sunflower and pressing oil for on-farm use. See links at the bottom of post for more about the host:

The workshop site is Tuckaway Farm, which has been hosting a biodiesel co-op for three years, and our host Dorn Cox and students from University of New Hampshire have built some impressive small-farm biodiesel production equipment there- inspired by Argentinian farm-scale biodiesel processors (theirs are somewhat of a hybrid of Appleseed systems and larger-scale techniques involving methanol recovery). They have also grown oilseed in conjunction with nearby UNH as experimentation in oil yields for farmers making their own fuel. There's a lot of information about Dorn and his projects in the articles linked at the end of this post.

The class will cover homebrewing basics but will also have a good tour of the farm-scale biodiesel equipment and will address the special issues that that scale brings up.
