Hydrogen is seen as the ultimate in clean fuels,especially for powering cars,because it emits only water. Burned ,in an experiment conducted at Purdue university in an Indiana, USA, the hydrogen is generated on demand, so you only produce as much as you need when you need it. According to Jerry woodall,an engineering professor at Purdue , who invented the system, hydrogen would not have to be stored or trasnsported, taking care of two stumbling blocks to generating hydrogen. For now, Purdue scientist's think the system could work for cars and truck as well, either as a replacement of gasoline or as a means of powering hydrogen fuel cells. According to Jay Gore,an engineer professor at Purdue Discovery Park, on its own alluminium will react with water because it forms a protective skin when exposed to oxygen. But pellets made out of alluminium and gallium can produse pure hydrogen when water is poured, on on them,offering apossible alternative to gasoline powered engines. wht is left over is aluminium oxide and gallium. In the engine, the by product of burning hydrogen is water. Infact,no toxic fumes are produced.
