[edit] $800/barrel claim unreliable source
The source is a blog article. It estimates $190/meter^2 capital costs and a maximum of 1.24 gallons/meter^2/year and then says oil would have to be $855/barrel to justify this. I doubt these numbers would get into a peer-reviewed publication. Also, there is an article where they associate this unreliable report with Wikipedia. [1] I have removed it.

[edit] Botryococcus braunii type of oil is not only one that can be hydrocracked
The claim that oil from this algae is special is not true. All vegetable oil is triglycerides which is glyceride in which the glycerol is esterified with three fatty acids. Any of these can be used as feedstock for hydrocracking. Vincecate 03:00, 3 December 2007 (UTC)

[edit] Algae species
Can one include the yield of the different algae species and add more species ?. --Mac (talk) 10:02, 17 January 2008 (UTC)
[edit] Links
Some links I consider interesting:
- Some people has asked in forums and other sites about where they can get bioreactors.
- gae Biofuel Equipment
- Solar Powered BioFuel Reactors: fully ecological equipment that does not produce greenhouse gases, because uses solar power.
- Oilgae, this can also be included as reference about the movement.
- Open Source Movement for Biodiesel from Algae - algOS. Open and free source is important to knowledge, including to the existence of Wikipedia and very usefull to produce biofuels from algae and combat global warming.

[edit] Lets play - Find the "."
"While using the oil in this manner does not require the additional energy needed for transesterification, (processing the oil with an alcohol and a catalyst to produce biodiesel), it does require modifications to a normal diesel engine, whereas biodiesel can be run in any modern diesel engine, unmodified, that is designed to use ultra-low sulfur diesel, the new diesel fuel standard for the United States of America that went into effect in the fall of 2006."
The above sentence is missing some periods.... can anyone tell us where they belong??Mantion (talk) 23:13, 5 March 2008 (UTC)
[edit] Biodiversity, Philippines
I added this landmark current research of Philippines due to its bio-diversity: Ateneo de Manila University's Department of Environmental Science, isolated Philippines species, on algal mass production to source out oil as alternative source of fuel. "Carbon dioxide as a product of aerobic decomposition can be utilized to enhance the growth of the algal species. Since the alga is also a rich source of proteins and carbohydrates, upon extraction of oil, the algae can still be utilized as food for livestock or fish; 1,000 to 10,000 gallons of algae are needed to produce a liter of biodiesel."abs-cbnnews.com, Ateneo scientists working on algae as biodiesel source --Florentino floro (talk) 06:36, 9 May 2008 (UTC)
- I wonder about the figure 1000 - 10,000 gallons of algae are needed to produce a liter of biodiesel. First, is gallons an appropriate unit to use for algae? does it refer to wet or dry algae? Plus, the numbers seem unbelievably high. Compare: about 10 pounds of olives (1-2 gallons) makes a liter of olive oil [1]. Further, this link [2] says algae can yield up 10,000 gallons of oil per acre, perhaps that's where the 10,000 gallons number comes from? Or are there 10,000 x 10,000 = 100 million gallons of algae per acre? maxsch (talk) 19:42, 9 May 2008 (UTC)

- Yes those figures of 1k - 10k gallons of algae are needed to produce liter of bio-diesel are wrong.. I will see if I can find a source with released figures. Your right it could be trying to companion the amount of water and area used to produce the algae. It is also strange that someone would use gallons and liters in the same sentence.. The whole statement is bogus.. I say just delete it.Mantion (talk) 10:10, 26 May 2008 (UTC)
[edit] Citation added
I've added a citation in paragraph 6 under "Biofuel production," where a citation was called for, after this sentence: "Open-pond systems for the most part have been given up for the cultivation of algae with high-oil content." I cited the UNH article, "Widescale Biodiesel Production from Algae," which also appears in the external links for this article, because that article does state that "most groups now working in this field (including our collaboration) have shifted to focusing on the use of proprietary photobioreactors." It goes on to explain that these solve a number of problems, including "takeover by low oil strains." While the emphasis here is on a single factor, as opposed to several in the UNH article, it is at least a viable source for the main claim in the sentence (open pond systems have been mostly given up).
Also, I've used a slightly different citation style (author first), because it includes more information and there does not seem to be a single approach used consistently in this article.
