Or, as the people at Toolmonger call it “Biodiesel for dummies”. The BioPro 190 from AGR Energy can produce 50 gallons of biodiesel every two days, runs off a domestic power supply and has a small footprint so it could sit unobtrusively in the corner of a garage. You still need to handle chemicals- methanol, lye and sulphuric acid- but they have tried to cut this to a minimum, claiming that one batch requires just half an hour of priming.
You could build your own biodiesel reactor for less, but I imagine a creative fast food outlet that incorporated one of these to fuel its fleet would have less trouble with health and safety than if they set up a bodge with oil drums in the back yard.
