Canola Power: Running your Car on Straight Vegetable Oil

  1. 1. 8 / - September 2008Around Dakota Ag Germans use veggie-oil fuel By JADE ESTLING T HIS winter, I traveled to Germany with four other people to visit farmers who are making their own fuel from canola. We toured smaller operations of less than a thousand acres and a fairly large operation of more than 8,600 acres. The four farms we vis- ited were diversified. They had mixed cropping rotations along with cattle (dairy or beef) or swine. One farm had a trucking company and a potato pro- cessing plant. The farmers said it was very im- portant to use small presses to pro- duce straight vegetable oil, or SVO, to use as a fuel. If they need more ca- pacity, they’ll add more small presses rather than installing a big press. One of the farmers explained that a larger press generates more heat.ON-FARM OIL: Robert Schauf holds a bottle of vegetable oil that he made from canola and will burn in his tractors.
