Algal Fuel
Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil. It is also carbon negative unless the dead plant matter is burned, as the energy (stored as hydrogen gas) is produced by solar photosynthesis and comes from the sun. The emissions from burning the hydrogen make up only water and air. Several companies and government agencies are funding efforts to reduce capital and operating costs and make algae fuel production commercially viable. Like fossil fuel, algae fuel releases when burnt, but unlike fossil fuel, algae fuel and other biofuels only release recently removed from the atmosphere via photosynthesis as the algae or plant grew. The energy crisis and the world food crisis have ignited interest in algaculture (far ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Algae Fuel In A Beaker
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthesis, photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular organism, unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the Macrocystis pyrifera, giant kelp, a large brown algae, brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in embryophyte, land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a phylum, division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Genetic Engineering
Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA is obtained by either isolating and copying the genetic material of interest using recombinant DNA methods or by artificially synthesising the DNA. A construct is usually created and used to insert this DNA into the host organism. The first recombinant DNA molecule was made by Paul Berg in 1972 by combining DNA from the monkey virus SV40 with the lambda virus. As well as inserting genes, the process can be used to remove, or "knock out", genes. The new DNA can be inserted randomly, or targeted to a specific part of the genome. An organism that is generated through genetic engineering is considered to be genetically modified (GM) an ...

Aquatic Species Program
The Aquatic Species Program was a research program in the United States launched in 1978 by President Jimmy Carter and was funded by the United States Department of Energy, which over the course of nearly two decades looked into the production of energy using algae. Initially, the funding of the Aquatic Species Program was to develop renewable fuel for transportation. Later, the program focused on producing bio-diesel from algae. The research program was discontinued in 1996. The research staff compiled their work and conclusions into a 1998 report. History Around 1978, the Carter Administration consolidated all federal energy activities under the support of the newly established U.S. Department of Energy (DOE). The DOE initiated research on the use of plant life as a source of transportation fuels. The Aquatic Species Program (ASP) was a small research effort intended to look at the use of aquatic plants as sources of energy. While its history dates back to 1978, much of the r ...

Chlorella Pyrenoidosa
''Auxenochlorella pyrenoidosa'', formerly ''Chlorella pyrenoidosa'', is a species of the freshwater green alga in the Division Chlorophyta. It occurs worldwide. The species name ''pyrenoidosa'' refers to the presence of a prominent pyrenoid within the ''Chlorella'' chloroplast. Uses ''Auxenochlorella pyrenoidosa'' has been used medicinally as a chelatory agent, for example to extract dioxins and dioxin-like compounds from the body. Possible medicinal uses include: * fibromyalgia * hypertension * ulcerative colitis The ''pyrenoidosa'' species have been used in traditional Chinese medicine. Boraas (1983) reported a mutation in a population of Chlorella pyrenoidosa kept in his lab as a food stock for a population of flagellates. Due to a malfunction of his equipment some of the flagellates got in the Chlorella's tank. This caused a mutation from unicellular to multicellular. For early work in this area, a science project by David and John Watkins at Fairborn High School teste ...

Chlorella
''Chlorella'' is a genus of about thirteen species of single-celled green algae belonging to the division Chlorophyta. The cells are spherical in shape, about 2 to 10 μm in diameter, and are without flagella. Their chloroplasts contain the green photosynthetic pigments chlorophyll-a and -b. In ideal conditions cells of ''Chlorella'' multiply rapidly, requiring only carbon dioxide, water, sunlight, and a small amount of minerals to reproduce. The name ''Chlorella'' is taken from the Greek χλώρος, ''chlōros/ khlōros'', meaning green, and the Latin diminutive suffix ''ella'', meaning small. German biochemist and cell physiologist Otto Heinrich Warburg, awarded with the Nobel Prize in Physiology or Medicine in 1931 for his research on cell respiration, also studied photosynthesis in ''Chlorella''. In 1961, Melvin Calvin of the University of California received the Nobel Prize in Chemistry for his research on the pathways of carbon dioxide assimilation in plants u ...

Microalgae
Microalgae or microphytes are microscopic algae invisible to the naked eye. They are phytoplankton typically found in freshwater and marine systems, living in both the water column and sediment. They are unicellular species which exist individually, or in chains or groups. Depending on the species, their sizes can range from a few micrometers (μm) to a few hundred micrometers. Unlike higher plants, microalgae do not have roots, stems, or leaves. They are specially adapted to an environment dominated by viscous forces. Microalgae, capable of performing photosynthesis, are important for life on earth; they produce approximately half of the atmospheric oxygen and use the greenhouse gas carbon dioxide to grow photoautotrophically. "Marine photosynthesis is dominated by microalgae, which together with cyanobacteria, are collectively called phytoplankton." Microalgae, together with bacteria, form the base of the food web and provide energy for all the trophic levels above them. ...

Algenol
Algenol, founded in 2009, headquartered in Fort Myers, Florida, Algenol is an industrial biotechnology company that is commercializing patented algae technology for production of ethanol and other fuels. The technology enables the production of the four most important fuels (ethanol, gasoline, jet, and diesel fuel) using a proprietary process involving algae, sunlight, carbon dioxide and salt water. History In 2008 the company announced it would begin commercial production of Ethanol by 2009 in the Sonoran Desert in northwest Mexico. This seems not to have happened though and as of 2015 they are still not in commercial production. In October 2015 Paul Woods, the founder, resigned and the company announced they were laying off 25% of the staff and changing to a “water treatment and carbon capture now, and maybe fuels later” focus.
