I think we have come to a readily available "end" solution for the problems we are facing right now. It's a diesel hybrid that can run on B100 and SVO (Straight [unused] Vegetable Oil) and WVO. Of course, it would have to be certified organically grown SVO, because we all know that fertilizers and pesticides are made from petrochemicals and the increased burden on our soils and planet to grow the extra oil stock would be horrendous if not organic. Perhaps a diesel hybrid could get 150mpg or more?
P.S. We changed our minds on the Jetta. We're going with a Jeep Liberty CRD. Not sure about converting it to WVO yet, but of course we can make our own B100...
