The U.S. aerospace industry is officially onboard the biofuel bandwagon, with the test fire of a small rocket engine that burns commercially available biodiesel. California-based Flometrics did the honours and discovered the Rocketdyne LR-101 engine produced nearly the same amount of thrust burning biodiesel as it did chugging through a kerosene-based conventional rocket fuel.
Could future trips to space be powered by vegetable oil? In a test firing earlier this month, the California-based engineering firm Flometrics announced that commercially available biodiesel produced almost the same amount of thrust as conventional rocket fuel. The find may not come as much of a surprise. After all, biodiesel is already being tested by the airline industry, which gobbles up billions of gallons of jet fuel each year.
