In the future, cars could fuel up with coffee grounds.


Gassing up with coffee. I’m Bob Hirshon and this is Science Update.
Some people just can’t get started each day without their coffee. Some day, the same may be true of their cars. Scientists at the University of Nevada are taking old coffee grounds and processing them into high quality biodiesel. They report that coffee grounds are twenty percent oil, and the biodiesel they produce from the grounds is high quality and car-ready.

In other science news, researchers at the University of Missouri report that there are 2.2 million acres of golf courses in the US, and seventy percent of those acres aren’t used for playing. They believe those acres could act as sanctuaries for endangered species. They’ve already found that in North Carolina, golf courses provide salamanders with critical habitat in areas with shrinking wetlands. I’m Bob Hirshon for AAAS, the Science Society.
