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.
10-4 each day

Topics covered in the homebrew production side of the class:
-biodiesel/SVO/solvent thinning options and history, biodiesel chemistry, testing oil (titration and water testing), making test batches, an overview of equipment, a chance to build your own reactor at the end of Sunday's class, quality control factors that influence conversion quality, quality testing, mistwashing and other water washing options, breaking emulsion, two-stage base biodiesel, waste water and glycerine disposal, irrigating with waste wash water, neutralizing wash water, water reuse, common pitfalls, hands-on experience recovering from failed batches and emulsion, safety, dewatering oil, spill prevention, burning glycerine for energy, hydronic heating or solar heating of your biodiesel system
