Bernard Tao, a professor at Purdue University, has recently found a way to make biodiesel, a renewable fuel made right here in Wisconsin, peform in temperatures of up to sixty degrees below Fahrenheit. Here are some facts:
- The new process for biodiesel production adjusts the ratio of saturated to unsaturated oils — which are already involved in the production process — instead of adding additional additives.
- Professor Tao and his team tested the biodiesel in Alaska and the Arctic Circle at subzero temperatures and never encountered any cold weather issues with the fuel.
- The additional production step only costs about five cents per gallon, which has a negligible impact on consumer prices for biodiesel.
