[Digestion] Directory: Biofuels from Algae Oil

[JGBellHimself]

Gooday to U2:
 
This is not only the last e-mail from me today, but probably for weeks or months.
In the mean time:
 
        "May your personal digestion keep working properly for you...!"
 
IF you you are interested in Algae Oil
you might want to take a look at this web site, and the information provided there.
True, is looks as if it is primarily focused on "biodiesel".
However, many new biodiesel efforts ARE looking at "algae" in very different ways.

Directory:  Biodiesel from Algae Oil
 

 
The advantages of deriving biodiesel from algae include rapid growth rates, a high per-acre yield; and algae biofuel contains no sulfur, is non-toxic, and is highly biodegradable. Some species of algae are ideally suited to biodiesel production due to their high oil content--in some species, topping out near 50%.

About Algae:
Oilgae.com (http://www.oilgae.com/) - Biodiesel from Algae Oil – Info, Resources, News & Links 
Algae range from small, single-celled organisms to multi-cellular organisms, some with fairly complex differentiated form. Algae are usually found in damp places or bodies of water and thus are common in terrestrial as well as aquatic environments. Like plants, algae require primarily three components to grow: sunlight, carbon-di-oxide & water. Photosynthesis is an important biochemical process in which plants, algae, and some bacteria convert the energy of sunlight to chemical energy. The existing large-scale natural sources are of algae are: Bogs, marshes & swamps - Salt marshes and salt lakes. Microalgae contain lipids and fatty acids as membrane components, storage products, metabolites and sources of energy. Algae contain anywhere between 2% and 40% of lipids/oils by weight. There are three well-known methods to extract the oil from oilseeds, and these methods should apply equally well for algae too: 1. Expeller/Press 2. Hexane solvent oil extraction 3. Supercritical
 Fluid extraction 
Biomass Yield:
Algal Biomass Yields versus Phytomass Yields of Tropical Crops (http://biopact.com/2007/01/in-depth-look-at-biofuels-from-algae.html) 
These are the yields obtained in stable cultures during an entire year, as reported by the Aquatic Species Program. All other results from that program show either unstable growth or yields obtained over short periods of time (often, during winter months when algae productivity drops significantly, the Aquatic Species Program discontinued the cultures.)
