The reading passage is about advantages of using fuel-cell engines instead of internal-combusion engines. The reading passage thinks that hydrogen is the main source of energy in fuel-cell engines and for some reasons is better than using petroleum which is main source of energy in internal-combusion engines. However, the lecturer diagrees with this idea and thinks that there are some problem in using and maintaining of hydrogen.
The reading passage thinks that petrolum is from finite source of energy and someday, we will run out of oil. But the hydrogen can be obtained by various sources and is renewable source of energy, But the lecturer thinks that hydrogen isnot easily avaliable and using this source instead of petrolum isnot practical. The lecturer thinks that creating pure liquid hydrogen costs lots of money.
The reading passage thinks that using petrolum will pollute the enviroment and using hydrogen will reduce this harmful affects on enviroment. But the lecturer thinks that maintaining hydrogen needs burning oil and coals which produces high pollution.
Finally, the reading passage thinks that using hydrogen is economically competitive, because people will spend less money and fuel-cell automobiles are twice efficient in using fuels. But the lecturer thinks that manufacturing fuel-cell engine is very expensive. Because fuel-cell engines need platium for creating electricity that is very expensive.
