After peaking in 1987, car and light duty trucks have not been able to increase mileage. In 2002, the average was 20.4 mpg with 2003 numbers at 20.7. Estimates are 20.8 mpg in 2004. Immense petroleum ingesting giants such as the Hummer fall outside government fuel economy rules. Auto companies think that cost increases to improve fuel economy would depress sales. (Ed.note, Will increasing world oil prices reduce sales without bumping car prices?)

The process may be adaptable to ordinary jets.
