Corn-fueled tour travels through Arizona

PHOENIX - How far would you go to end America's dependence on foreign oil?

Tom Holm is going 10,000 miles over the next two months, at the wheel of what would appear to be a big, thirsty, polluting pickup ... a Ford F-250 Super Duty. But it's a flex-fuel model, and Tom, the executive director of EcoTrek , a non-profit foundation that researches and promotes renewable fuels and materials, is running it on cellulosic ethanol.

"You've got a clean, organic biofuel made in America that will run your vehicle and still allow you to keep its power," Holm says.

Cellulosic ethanol uses the parts of corn you can't eat, husks and stalks, so it doesn't take food off anyone's table, which critics say regular corn-based ethanol does.

Holm's truck also features seats made from a material that comes from recycled plastic bottles.

Two months on the highway with his wife and three kids waiting home in L.A. Ten thousand miles at the wheel. Is it worth it? Can a one-man roadshow change America's dependence on fossil fuels?

"Not only do I think I'm going to change minds, I know that I'm changing minds now. I see the emotion and the spirit in the people that I talk to," Holms says. "They want American-made fuels. They want America's energy dollars to stay in America."

Holms' "Best of America" tour will bring him back to Arizona in late March. To follow its progress, follow Tom's blog .
