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 wh

The reading and the lecture both are regarding hydrogen based fuel-cell engine. The author of the reading states that it is an efficient solution and has potential to replace internal combustion engine whereas the lecturer have divergent opinion on this topic. The lecturer casts doubts on the main points mentioned in the reading by providing three reasons.

Preeminently, according to the reading petroleum is a finite resource and will eventually run out. In addition, to this author points out that hydrogen is available in variety of sources and will not be depleted so easily. However, the lecturer disputes this point. She claims that hydrogen is not that easily available as it is required in pure liquid state. Furthermore, she points that high advancement in technology is needed as this form of hydrogen needs to be stored in cold region of around negative two hundred and fifty three degree celcius.

By the same token, the reading states that hydrogen based fuel-cell engine would solve pollution problem as the byproduct of hydrogen is water whereas that of traditional internal combustion engine is carbon dioxide. Nevertheless, the lecturer refutes this argument. She claims that to obtain pure hydrogen it has to undergo purification process which meant that coal and oil have to be burnt which will lead to environmental damage.

In winding up, the reading contends that there will be economic advantage with hydrogen based fuel-cell as they would require only half the fuel to cover same distance as the traditional engine. In contrast, the lecturer's stance is that it would not be economically advantages as hydrogen based fuel-cell require platinum which is rare and expensive material, without which the hydrogen would not be able to undergo any reaction.
