Document Summary

Today will be short, about 1 hour and then the professor will be in the answer questions to help prepare you for your exam. Next week will have a slightly easier reading and it will also be shorter because of the mid-term coming up. We looked at 3 papers regarding bio-fuels and the energy it takes to produce them. One of the main goals of last week was to emphasize how critical it is to read critically. The publishing in peer journals can make errors and produce work that is unreliable and can raise questions about their scientific objectivity. We ran out of time at the end of last session to talk about the second purpose of the papers which was to evaluate the usefulness of bio-fuels as alternative energy sources. Even taking into account the short-comings the papers that we read, i think there are serious questions of the viability of bio-fuels as the alternative to liquid fuels.

With peak oil a reality, a lot of research is being put into alternative energy sources. One area in particular is biofuels.

There are 3 broad categories of biofuels:

1st generation: made from food crops

2nd generation: made from organic wastes , crop residues, forestry residues, etc.

3rd generation: made from microalgae

Depending on the processes used, a variety of fuels can be made from each of the generations, including bioethanol and biodiesel.

Read the following article: https://www.eniday.com/en/technology_en/the-future-of-biofuels/

and watch the following Youtube video: Biofuels: Beyond the Headlines

Comment on how you see biofuels fitting into the energy mix. Are they sustainable? Ethical? An improvement over conventional oil? Also, comment on the video and how realistic you think it is. Are they giving the whole truth? Are they accurately representing the biofuel industry?

Your assignment is to find an interesting article related to science. Read and then briefly summarize it. Post your summary and if possible a link to the article if it is online. If it is not accessible online post the name of the journal it can be found in, the title of the article, the date it was published, and the author of the article. Related to science means you have a huge variety to pull from, examples could be nutrition, genetics, introduced species, global climate change, alternative energy sources, etc.

No copy paste!
Guidelines:

1. Make sure the article is scientifically sound. There are several very interesting science journals such as Nature, Lancet, Chemistry Today, etc. but you do not have to limit yourself to those specific ones. There are plenty of other quality magazines available either in the library or online such as National Geographic, Science, Popular Science, Smithsonian, etc.

2. The article you are reviewing must be at least one full page at a minimum. Too many articles are "sound bites" consisting of only a meager paragraph or two. I do not think you can write enough about a one paragraph blip posted online and still get full credit. How do I determine if the article you chose is one page? I am not going to count the number of words. Use your common sense here. If you can't write more than a short paragraph about the article, then the article was not long enough. Articles that are too short will not receive full credit.
