summarise the points made in the lecture, being sure to explain how they case doubt on specific points made in the reading passage.
Car manufacturers and governments have been eagerly seeking a replacement for the automobile's main source of power, the internal-combustion engine. By far the most promising alternative source of energy for cars is the hydrogen-based fuel-cell engine, which uses hydrogen to create electricity that, in turn, powers the car. Fuel-cell engines have several advantages over internal-combustion engines and will probably soon replace them.
One of the main problems with the internal-combustion engine is that it relies on petroleum, either in the form of gasoline or diesel fuel. Petroleum is a finite resource; someday, we will run out of oil. The hydrogen needed for fuel-cell engines cannot easily be depleted. Hydrogen can be derived from various plentiful sources, including natural gas and even water. The fact that fuel-cell engines utilize easily available, renewable resources makes them particularly attractive.
Second, hydrogen-based fuel cells are attractive because they will solve many of the world's pollution problems. An unavoidable by-product of burning oil is carbon dioxide, and carbon dioxide harms the environment. On the other hand, the only byproduct of fuel-cell engines is water.
Third, fuel-cell engines will soon be economically competitive because people will spend less money to operate a fuel-cell engine than they will to operate an internal-combustion engine. This is true for one simple reason: a fuel-cell automobile is nearly twice as efficient in using its fuel as an automobile powered by an internal-combustion engine is. In other words, the fuel-cell powered car requires only half the fuel energy that the internal-combustion powered car does to go the same distance.
Recently, there has been a debate as to seeking a replacement for the automobile's main source of power, the internal-combustion engine.
More specifically, concerning the passage, the writer put forth the idea that replacing the hydrogen-based fuel-cell engine instead of using petrol. In the listening passage, the lecturer is quick to point out there are some serious flaws in the writer's claim. The lecturer believes that the idea of using hydrogen-based fuel-engine is correct but it has some problems that don't let us replace it with petrol. She addresses, in detail, the problems with each point made in the text.
First and foremost, the author,s of the reading states that the main problem of the hydrogen-based fuel-cell is it relies on petroleum. Hydrogen can be derived from various sources such as natural gas and even water. But the form which we needed to use in the engine is different. Some professionals in the same field, however, stand in firm opposition to this claim. In the listening, the lecturer states that the way the writer says is too optimistic. She goes on with the idea that we need the liquid form of hydrogen and for making that we need to do the purification process which not easy. Beside is difficult to make a liquid form of hydrogen, it is also difficult to store it because it needs a very low temperature.
Another reason represented by the writer is that he thinks hydrogen-based fuel can solve the world's pollution problems. But the lecturer believes that it's wrong. She said that maybe the process of making pollution changes but the issue remains. In this, the cars won't be the source of pollution, the factories which generate the liquid hydrogen need lots of oil and gas for the purification process.
Finally, the author wraps his argument by positing the idea that the hydrogen-based fuel-engine are more economically. He claimed that a fuel-cell automobile is nearly twice as efficient in using its fuel as an automobile powered by an internal-combustion engine is. But, the lecturer states that it will cost more. this will be more expensive.
To sum up, both the writer and lecturer hold conflicting views about the replacement of the hydrogen-based fuel-engine.
