A key topic of many technical discussions has been the development of alternative fuels to power the compression ignition engine. Reasons for this include the desire to reduce the dependency on petroleum-based fuel and, at the same time, to reduce the particulate matter (PM) and NOx emissions. Also, there has been interest generated in the diesel engine because of the reduction in greenhouse gases that has been proposed during the 2008-2012 time frame in Europe and the regulations that affect diesel engines in the United States.

This report reviews concepts behind fuel cell technology, describes the improvements and vehicles that have been developed since 2001 as the technology has been refined, and examines the issue of what fuel should be used and the necessary refueling infrastructure. Chapters include: The Fuel Cell Vehicles The Race Is On Refueling Infrastructure The Future and more

A recent research report released by the U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA) has stated that almost 175,000 pedestrians died on U.S roadways between 1975 and 2001. It was also noted in the report that 12% of all deaths related to motor vehicle crashes in the country are pedestrian fatalities. Most of the safety technology to date in vehicles has been applied to protect the occupants in the vehicle. What can vehicle manufacturers do to reduce pedestrian fatalities?
