ABSTRACT
As the price of petroleum for gasoline and diesel engines converges with that of alternate energy sources, new power systems will become more widely used. One goal was to reduce the amount of petroleum used for transportation by promoting the use of alternative fuels in cars and light trucks. These fuels included natural gas, methanol, ethanol, propane, electricity, and biodiesel. Small neighborhood electric vehicles have been gaining popularity throughout the United States and in other parts of the world. The road to hydrogen vehicles and a hydrogen fueling delivery system may take many paths. Hydrogen powered internal combustion engines could promote the infrastructure for fuel cell cars. The Ecostar was the first electric vehicle that resembled an actual production car instead of a conversion. A fuel cell car, bus or truck is in essence an electric vehicle powered by a stack of hydrogen fueled cells that operates like a refuelable battery.
