In these set of materials, the article discusses the advantages of the hydrogen-based fuel-cell engines for running cars over the internal combustion engines, and how it can be a solution for the pollution problems and the oil limited sources. However, the professor disagrees with the reading, she believes that the article is way optimistic and hydrogen-cell engines are not the ideal solution for those problems.

First, the reading claims that the renewable resources for fuel-cell engines gives them a big plus over the oil- based engines because we will run out oil one day. However, the professor opposed this idea, she says that the needed hydrogen to produce energy in the hydrogen -based should be in a pure liquid form and cannot be produced easily, and it needs a high technology to produce it. It is not easily available and not practical.

Second, the reading avers that hydrogen-based fuel engines are attractive because they will solve many of the world pollution problems. Conversely, the professor refutes this idea; she says that even though the final product of running the fuel-cell engine is water instead of carbon dioxide in the internal combustion engines. The process of producing hydrogen to run hydrogen-based engines is so polluting. It needs to burn coal and produce pollution.

Third, the author posits that fuel-cell engines is so competitive because people will spend less money on those engines comparing to the internal-combustion engine. However, the professor refutes this point by saying that fuel based engines needs platinum element, which is very rare and expensive, and efforts to replace this elements were unsuccessful.
