Commonly, car that glides on the road using a petrol engine ( known as gasoline engine in North America ). Petrol engine is an internal combustion engine with spark-ignition. Differs from a diesel engine which only using compressed air to generate heat or ignition.
The combustion of petrol ( as a raw material in petrol engine ) which consist of hydrocarbons between 4-12 carbon atoms per molecule will produce carbon dioxide, carbon monoxide, carbon and water. These products are greenhouse gases as it transmits visible light but absorbs strongly infrared. This will cause the Earth's average temperature increase which called global warming.
There are many things that had been done to reduce the carbon dioxide concentration in atmosphere such as car pooling, using bicycle to work ( most demonstrated in Japan ) and the latest one, the invention of hybrid vehicle. Hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle which combine an internal combustion engine and one or more electric motor. It is much more green than petrol engine car but still need help of internal combustion engine.
How about we change the usage of petrol to hydrogen gas. Though it is explosive but mens technology and creativity can create some kind of hydrogen engine which much more environmental friendly due to this equation.
2H2O + O2 -> 2H2O
Combustion of hydrogen will produce water and it is not harmful to environment. I really hope, before god call me to live in the Heaven, i can see my idea berome realistic.
