The possibility of $1-a-gallon fuel would make a lot of US governmental entities sit up and take notice. The state of Oklahoma and the city of Dallas are making that happen. Those two entities are buying up a bunch of Ford F-150 pickups retrofitted to run on compressed natural gas (CNG), all in the name of cost savings and emissions reduction.
When the best-selling US truck sheds the equivalent weight of three football fullbacks by shifting to aluminum, folks start paying attention. Oak Ridge National Laboratory took a closer look at whether the reduced fuel consumption from a lighter aluminum body makes up for the fact that producing aluminum is far more energy intensive than steel. And the results of the study are pretty encouraging.
