Hydrogen Powered Cars
Hydrogen, the simplest element, is composed of one proton and one electron. It makes up more than 90% of the composition of the universe. More than 30% of the mass of the sun is atomic hydrogen. It is the third most abundant element in the earth's surface, and is found mostly in water. Under ordinary conditions, hydrogen is a colorless, odorless, tasteless, and nonpoisonous gas composed of diatomic molecules (H2). When cars burn gasoline, they would ideally burn it perfectly and create nothing but carbon dioxide and water in their exhaust. Unfortunately, the internal combustion engine is not perfect. In the process of burning the gasoline, it also produces; Carbon monoxide, a poisonous gas , Nitrogen oxides, the main source of urban smog , unburned hydrocarbons, the main source of urban ozone . Catalytic converters eliminate much of this pollution, but they aren't perfect either. Air pollution from cars is a real problem in big cities. Carbon is also a problem. When Carbon burns, it turns into a lot of carbon dioxide gas. Gasoline is mostly carbon by weight, so a gallon of gas might release 5 to 6 pounds of carbon into the atmosphere. The U.S. is releasing roughly 2 billion pounds of carbon into th
