algae biodiesel what does that mean (roleplayed out)
bio-gamma-linolenic acid oil from mold
envirementalists love oxigen right ethonal doesn't seem to fit the bill unless you get rid of the yeast. It would seem that fish ponds and algae ponds would be a natural combo. alot of biomass for something anyway livestock or whatever..
looking for a thesis on creating oxigen first and then ethonal...
So, to get one gallon of oil (around 8 pounds actually), you'd need about 17.8 pounds of algae (with 50% oil content, and 90% extraction efficiency). The remaining biomass can be used as well, extracting protein for animal feed, and converting the rest either to alcohol or diesel (through a couple of options, with varying efficiencies and economics. Gassification and methanol or Fischer Tropsch synthesis, or pyrolysis, etc.).
Energy source
Algae can be used to produce biodiesel (see algae culture), and by some estimates can produce vastly superior amounts of oil, compared to terrestrial crops grown for the same purpose. Because algae grown to produce biodiesel does not need to meet the requirements of a food crop, it is much cheaper to produce. Also it does not need fresh water or fertilizer (both of which are quite expensive).
Algae can be grown to produce hydrogen. In 1939 a German researcher named Hans Gaffron, while working at the University of Chicago, observed that the algae he was studying, Chlamydomonas reinhardtii (a green-algae), would sometimes switch from the production of oxygen to the production of hydrogen.[3] Gaffron never discovered the cause for this change and for many years other scientists failed in their attempts at its discovery. In the late 1990's professor Anastasios Melis a researcher at the University of California at Berkeley discovered that if you deprive the algae of sulfur it will switch from the production of oxygen (normal photosynthesis), to the production of hydrogen. He found that the enzyme responsible for this reaction is hydrogenase, but that the hydrogenase will not cause this switch in the pressence of oxygen. Melis found that depleting the amount of sulfur available to the algae interrupted its internal oxygen flow, allowing the hydrogenase an environment in which it can react, causing the algae to produce hydrogen. [4] Chlamydomonas moeweesi is also a good strain for the production of hydrogen.
Algae can be grown to produce biomass, which can be burned to produce heat and electricity.

C. Barry Raleigh, a researcher with the Hawaii Natural Energy Institute, is studying the use of algae as a source of fuel. Raleigh said there are varieties of algae composed of 30 percent to 40 percent oil, which can be refined into a biodiesel fuel much like regular diesel engine fuel.

this comapany may be a problem... They claim alot of oil is left after making corn ethonal and their algie produce 6% rather than 40% oil..

It appears Aqib Talib pulled a Plaxico Burress.
When news first broke that the Denver Broncos cornerback Nike Air Max 90 had been shot, the details were awfully strange, as Talib told Dallas police, “Everything was a blur Nike Free Run and I was too intoxicated to nfl jerseys store remember what happened,” wholesale nfl jerseys the location of the shooting NFL Jerseys – either a nightclub or a neighborhood Nike Air Max 2015 Shoes park (or a grassy knoll, perhaps?) – was called into question, and a police Nike Roshe Run report claimed the bullet entered his right thigh and exited his right calf, cheap nfl jerseys which suggested it traveled straight down his leg.
