In Wichita, Kansas, Jonathan Goodwin says that may no longer have to be the case:
Goodwin is making a name for himself -- and his company, H-Line Conversions -- by turning gas-guzzling behemoths like Hummers, Cadillac Escalades, Jeeps and other big American cars into clean-power machines.
The first thing he does is remove the old inefficient engine -- even if it's a brand new vehicle -- and replace it with a diesel engine that can run on biodiesel.
"It's the transformation of what I call old technology to new technology," Goodwin says.
