Car Manufacturers and Fuels
The passage mentions numerous disadvantages of using internal-combustion engine automobiles and suggests that utilizing Fuel-cell engines would alleviate issues associated with the existing engines. The professor in the lecture agrees with the reading about the problems of engines that rely on Petroleum fuel, but she refutes the idea that hydrogen-based fuel cells would optimistically become practical.
Firstly, the reading points out that oil-based fuels are finite resources, whereas hydrogen is abundantly available in the environment. The lecturer, however, asserts that even though hydrogen is readily available, it is not in an appropriate form to be adopted in the car engines to produce electricity. According to the professor, hydrogen must be in the form of liquid which is technologically difficult to maintain it in this artificial state.
Secondly, the professor challenges the passage that hydrogen-based automobiles will not harm the environment by mentioning that producing hydrogen fuel in the manufacture requires a lot of energy for procedures such as the purification, and as a result, providing such energies requires burning coal or oil which would bring about pollution to the environment. So, even though the cars will not pollute, the fuel manufacturer will contaminate the air.
Finally, the lecturer refutes the speculation of the writer that utilizing hydrogen-based automobile would be cost-effective. In contrast, she alleges that some expensive material such as Platinium is required for manufacturing such engines because the investigations have demonstrated that employing cheaper materials would cause the hydrogen to fail in chemical reactions required for producing electricity and power source of the automobile. Therefore, she claims that these cars would be expensive, and people might not be attracted to them because of financial benefits.
