With the speculation by many leading geologists that petroleum reserves will be exhausted within the next fifty years, a number of alternatives to petroleum have been proposed. One of the most promising alternatives being researched is hydrogen cell technology, which could easily replace traditional gasoline as fuel for automobiles. The adoption of hydrogen as an alternative fuel has many advantages.
First, hydrogen is one of the most abundant elements on the planet. It is a naturally occurring element that can be found around the world. One of the most common sources of hydrogen is H20, or water, which consists of two hydrogen atoms and one oxygen atom. Since water makes up over seventy-five percent of the Earth, hydrogen would be an ideal source of energy for nearly all countries on the planet.
Moreover, hydrogen can be concentrated and stored in small containers called "cells." Hydrogen cells are smaller and far easier to transport than gasoline, since they can simply be stacked on a truck for transportation instead of carried in a large tank. Unlike gasoline, which can leak out of the tank and catch fire if there is an accident, hydrogen cells' easily transportable form makes them far safer to move.
Additionally, when placed in cars, hydrogen is much more efficient than gasoline. It takes far more gasoline to move a car across a certain distance than it does for hydrogen. In fact, hydrogen fuel cells can transform twice as much energy into power as gasoline can. Adopting hydrogen cell technology in automobiles would vastly improve the efficiency of our vehicles. As such, countries looking to adopt new sources of energy would be wise to research hydrogen as an alternative fuel source.
Both the article and lecture talk about the alternative energy resources for gasoline, since gasoline is no infinite. The reading offers the hydrogen gas as a wonderful alternative for gasoline in the future, and provides three convincing reasons of support. Conversely, the lecturer believes that hydrogen cannot be a suitable energy resource although the author proposes. The professor repudiates all the reasons of the author respectively.
First, the lecture enumerate the first advantage of hydrogen as one of the most aboundent element on Earth. It asserts that hydrogen is one element in water, and water includes 75 percent of our palnet. Then hydrogen is an endless resource for us. On the other hand, the speaker refutes this idea by saying that hydrogen in pure form is rare, although it seems as a plenty material. She mentions that water has another element besides hydrogen in its compound. If we want to use hydrogen from water we should get rid of ocygen. She believes that hydrogen is not available in elemental pure form in this huge amount that readig supposed.
Second, the article claims that hydrogen can be concentrated and store in small cells. Hence, using hydrogen in smaller tank transport easily than gasoline. The author asserts that transportation of hydrogen is safer than gasoline. Controversially, the spopkeswomen rebuts this advantage by saying that hydrogen is a very flamable gas. Hydrogen can explode. It is one of the most flamable materials which it is used in bombs. She avers that if a car with hydrogen get fired in the highway, it will make a massive explosion. She mentions that gasoline burns not explodes like hydrogen. Consequentely, hydrogen cannot be a suitable substitute for gasoline.
Third, the article posits that hydrogen is more efficient in cars rather than gasolline. It points out that hydrogen has an index of efficiency twice more than gasoline. However, the professor says that superficially hydrogen has more efficiency than gasoline, in real work it has not. She insists that to make a pure hydrpgen we must use a lot of energy which will decrease the yield of hydrogen energy. She asserts that the author's information in this regard is misleading because it did not consider the energy which we need in the purification process.
