The author describes that the hydrogen-based fuel-cell engines have several advantages over internal-combustion engines and provides three reasons to support this claim. On the other hand, the lecturer states that even though internal-combustion engines harm the environment and petroleum is a finite resource, hydrogen-based fuel-cell engines do not solve the problem and the reading is too optimistic in its assessments and refutes each of the author's reasons with rational grounds.
First of all, the writer states that internal-combustion engines rely on petroleum, which is a finite resource, and it will run out in the future. Nevertheless, the professor states that hydrogen is not easily available. Although Hydrogen is present in water, it cannot be directly usable. Hydrogen can be obtained in the pure liquefied state, which is an artificial substance, and need high technology, such as elaborate cooking technology to produce practical hydrogen.
Second, according to the reading hydrogen-based fuel cells are environmentally friendly fuels which are a good solution for pollution problems. Conversely, the speaker brings up the idea that despite the fact that hydrogen-based fuel cells do not harm the environment, the purification process of hydrogen produces a lot of pollution. To be more specific, purification is accompanied by burning coal and oil which cause lots of pollution.
Third, the writer expresses that using fuel-cell engines is cheap. However, the lecturer posits that fuel-cell engines process needs platinum, which is a rare and expensive metal and has a crucial role in a chemical reaction in the engine for the sake of producing electricity in the automobiles.
Therefore, the points mentioned in the reading do not make any sense.
