been reading up on the biodiesel and it seems to be doable they have smaller reactors that can fit in a small trailer basicly they pour ethyl alcohol with the cookingoil and bring the accidity down with sumtin that looks like a chemical used to declog a sink , this needs to be precice , when done correct the vaseline like stuff will float on top of the biodiesel (or was it the other way round .
you need to flushclean the biodiesel after its made to remove the last of the ethyl and the acidity stuff then wait until its seperated again and remove the water then leave the biodiesel in an open vessel to vapourize the last bit of water and alcohol in there .
if you heat the cookingoil or rapeseedoil or simulair enough you can drive on that too when you run an oldfasioned diesel with a line pump and low pressures , the newer TDi engines use idioticly hight fuelpressures and realy fine holes in the injectors , those whont work with the raw stuff cause it will be too thick and clog up the injectors
