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 can not 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.
The reading passage and lecture have conflicting opinions about whether the vessels which were discovered by local inhabitants contain electric batteries of earlier times. The lecturer adamantly delineates that three compelling assumptions prove it creates electricity. On the other hand, the author strongly postulates that there is not enough evidence to believe it carries electrons.
First and foremost, according to the professor in the lecture, vessels were discovered by local people, not archaeologists. that means it is highly possible that the residents might overlook its importance or not recognise the electrical conductors which were near the vessels. Since they were not trained people, they even could throw away it. Nonetheless, the article offsets these points by declaring that if it was utilised as batteries, they would definitely contain some electricity conductors such as metal wires.
Secondly, the professor further asserts that even though jars were alike to some copper cylinders which were discovered near this area, there is no evidence to prove it. Additionally, if these containers were originally designed as keeping sacred notes, they might have been repurposed as generators of electricity. To be more specific, it was created as only one purpose at the beginning, but later it adopted another intention. These claims refute the writer's indications about the jars are similar to some findings which near its founded area. In addition to this, it could be used as providing scrolls of divine texts which was founded as broken apart in some area.
Lastly, the speaker in the lecture insists that they might have been used as healing patients by ancient doctors because they were very similar to some modern therapies. Furthermore, she points out that they were perceived as invisible power for earlier humans due to its features of causing mild shock and tangling. The author counters these indications by suggesting that in the past, there was no need for generating electricity because there was no equipment rely on electricity.
