6. The best green technologies in cars We should use electric motors and hydrogen fuel cell. If possible, we can combine them together to create ‘the greenest car’ in the world. Let me first introduce to you how both electric motors and hydrogen works. In a flame of pure hydrogen gas, burning in air, the hydrogen (H 2 ) reacts with oxygen (O 2 ) to form water (H 2 O) and heat. It does not produce other chemical by-products, except for a small amount of nitrogen oxides. Hence a key feature of hydrogen as a fuel is that it is relatively non-polluting (since water is not a pollutant). Pure hydrogen does not occur naturally; it takes energy to manufacture it. Once manufactured it is an energy carrier (i.e. a store for energy first generated by other means). The energy is eventually delivered as heat when the hydrogen is burned. The heat in a hydrogen flame is a radiant emission from the newly formed water molecules. The water molecules are in an excited state on initial formation and then transition to a ground state, the transition unleashing thermal radiation. When burning in air, the temperature is roughly 2000°C. Hydrogen fuel can provide motive power for cars, boats and aeroplanes, portable fuel cell applications or stationary fuel cell applications, which can power an electric motor. Hydrogen:

8. Since the electric motor method requires electricity, we can get electricity from the hydrogen technique. The electricity from the hydrogen technique can be used to propel make the electric motor move. When the electric motor moves, the car can move too! This combination of methods do not requires petrol, and also not complicated and expensive. In this way, we will not pollute the environment. And even when we are getting the electricity from the hydrogen technique, only nitrogen oxides is produced, and not other harmful substances. Conclusion: Conclusion
