As crude prices push toward $100 a barrel and gasoline in many parts of the country is selling at more than $3 a gallon, some SUV owners are looking for ways to improve their fuel economy.

Johnathan Goodwin in Wichita, Kan., says he has the answer.

Goodwin is converting Hummers, Escalades and other large SUVs to run on biodiesel.

While the conversions are costly, he's able to double the fuel efficiency of the vehicles, boost their power and dramatically cut emissions.
