Salt Lake City, UT – A small underground movement is growing in and around the Salt Lake Valley. And its after one thing. Used kitchen grease. As gas prices soar and the Earth heats up, a handful of tinkerers and optimists are taking the future into their own hands. They're brewing used vegetable oil from the back of restaurants in their homes, converting it into to biodiesel - a clean-burning fuel. As KUER's Jenny Brundin reports in the first of a 2 part series on bio-diesel - there's really no such thing as a typical biodieseler here.
