People today are always complaining about something, and one of the popular topics is the price of gasoline. Older generations remember a time when gasoline could be purchased for a quarter of a gallon; a big difference from the three to four dollars paid today. It doesn't help that America is so dependent on foreign countries for its gasoline supply.1 And with conflict in the Middle East, gasoline prices are more uncertain than ever; prices go up and down in the blink of an eye these days. For these reasons, as well as global warming, scientists have been experimenting with alternative fuels to replace fossil fuels. Some of the features scientists are looking for are availability and low emissions. And one of these alternative fuels is hydrogen.1 Hydrogen, with an atomic weight of 1.0, is the lightest element on the periodic table.2 And although most people don't consider it as a fuel, it was used by NASA as fuel. and others for industrial processes.3 Some people may remember the Hindenburg and how hydrogen was blamed for the accident. Popular belief was that the hydrogen contained in the zeppelin had burned with the oxygen in the air and caused the explosion; but Addison Bain, a retired NASA engineer, concluded that the real cause was the skin covering the airship.3,4 The skin was made of cotton coated with iron oxide and cellulose butyrate acetate; Cellulose butyrate acetate also contained a suspension of aluminum powder.3 The compounds are essentially ingredients for a solid rocket propellant.3 The airship caught fire from an electrostatic discharge that ignited the skin.3 While the hydrogen inside the airship didn't help matters when it caught fire, it wasn't the ma...... middle of paper ......2007.2.
