Both the reading and the lecture discuss the merits and demerits of using fuel-cell engine instead of internal- combustion engine. The reading focuses on the advantages of using the fuel- cell engine and it provides three points of support.However, the professor disproves these advantages and refutes each of the author's reasons.
First of all, the reading states that internal- combustion engine rely on petroleum in form of gasoline or disel , which are finite resources.While, hydrogen-fuel cell engine will not depleted. On the other hand, the orator stated that hydrogen-fuel cell engine is not the solution since hydrogen is not available and it must be pure .Hydrogen in pure form is artificial which is very difficult to produce.As a result, using hydrogen- fuel cell engine is not practical.
Furthermore,hydrogen- fuel cell engine will solve the pollutin problem.However, the professor oppose this idea by explainig that pure hydrogen is a significant source of pollution .Since the pure hydrogen result from the chemical process in which the using of hydrogen and gas create burning coal and oil that pollute the environment.
Finally, the passage asserts that fuel- cell engine is more economic than internal combusation engine. Conversely,the professor refute this point by stating that the manufacture of hydrogen is very expensive as it is made of platinium which is highly costing and no other material can replace the using of platinum to save money on the cost of producing hydrogen from platinum.
As shown the lecture refutes each point in the passage.
