I worked as a certified pipe weldor for the Fitters’ union in Cheyenne, WY, for 9 years.  Much of my time was spent in refineries and power plants, and I developed an affinity for pipe systems.  So in the winter of ’09, I built a biodiesel plant behind my shop in Cayucos.  A thing of beauty (for those with eyes to see), my plant was visited by the Biodiesel  Club of Cal Poly, and I received invaluable help from the physics professor there.
