As the saying goes, necessity is the mother of invention. That can be re-interpreted, for automakers, as the more consumers want your car, the more money they’ll spend your way. And what consumers want right now is better gas mileage, as gas prices continue to climb towards that magical $3 a gallon mark.

Bob Brooks of Consumer Guide reports on one technology, the hydrogen-boosted engine, as a possible future consumer demand. This gas engine injects hydrogen in the regular air/fuel mix of a normal gasoline powertrain. Fuel economy is increased by as much as 30-percent. Other advantages include very little NOx emissions, and low installation costs. The biggest issue, of course, is the lack of hydrogen-fueling stations.

The technology was developed by researchers at the Massachusetts Institute of Technology, with ArvinMeritor and IAV currently developing it. An SUV is being equipped with the engine for trials, with the first production vehicle planned for delivery by 2010.
