This has the promise of something exciting and he's certainly right about the cross pollination from amateurs.
My wife just bought a big ass F250 pickup with the 7.3L Powerstroke diesel and that immediately began to feed my interest in biodiesel.
My background is in designing controllers and writing software to control machinery. As I was researching the amateur ways of making diesel from waste vegetable oil, I was struck by how it lends itself to automation: pour WVO in at one end, push a button and get diesel and glycerine out the other. But yet almost everyone still seems to be doing it by hand in their garages.
