anaerobic
Author: webmaster | Growing, living or occurring in the absence of molecular oxygen. |
| | |
anaerobic digestion
Author: webmaster | AD refers to the breakdown of organic materials due to a combination of hydrolysis and symbiotic anaerobic bacterial processes in an oxygen free environment. Key product is biogas, an 'organically' produced hydrocarbon fuel. see also biofuel, methanogenesis, methanogens & fossil fuel. |

anoxic
Author: webmaster | absence of oxygen |

archaea
Author: webmaster | Discovered by Carl Woese in the late seventies they were initially believed to be bacteria, but are a unique group of microorganisms. They are genetically and metabolically different from all other known bacteria. They appear to be living fossils, the survivors of an ancient group of organisms that bridged the gap in evolution between bacteria and the eukaryotes (multicellular organisms). The name Archaea comes from the Greek archaios meaning ancient. see also http://www.ucmp.berkeley.edu/archaea/archaea.html |

biofuel
Author: webmaster | a fuel derived from bios (greek for life) opposite of fossil.
A gaseous, liquid, or solid fuel that is produced by completely natural biological processes from 'raw' organic materials. |
| | |
biogas
Author: webmaster | 'biogas' results from anaerobic microbial [living] degradation/decomposition of organic materials. It typically consists of somewhere between 55 and 75 % methane and 45 to 25 % Carbon Dioxide and may contain trace amounts of Hydrogen Sulfide.

| C.H.P. | Combined Heat and Power production. |
| | |
| co-generation | synergistic generation of multiple types of energy, i.e. heat and electricity in order to achieve optimum fuel energy content conversion. I.e. very high efficiencies. |
| | |
| crude | Being in an unrefined or natural state; raw, archaic. A substance, especially petroleum, in its unrefined state.
Manure is a crude that can be refined into highly valuable fertilizer by anaerobic digestion. - byproduct is a hydrocarbon fuel: methane.
|
| | |
| digestate | anaerobic digester output material that is - if digestion was complete - biologically stable and pathogen free with predictable fertilizer value. |
| | |
| E85 | refers to an internation standard for a vehicle fuel comprised of 85% denatured ethanol and additives that can be mixed [mingled] with standard gasoline to provide flex-fuel.
|
| | |
| electricity | The physical phenomena arising from the behavior of electrons and protons that is caused by the attraction of particles with opposite charges and the repulsion of particles with the same charge.
- The physical science of such phenomena. - Electric current used or regarded as a source of power.
- Intense, contagious emotional excitement.
|
| | |
| engine | A machine that converts energy into mechanical force or motion.
different from an electric, spring-driven, or hydraulic motor by its use of a fuel.
|

fossil fuel
Author: webmaster | hydrocarbon fuel derived from dead matter of a previous geologic period |
| | |
| fuel alcohol | produced entirely from organic sources by fermentation.
It is a flammable liquid hydrocarbon suitable for use in internal combustion engines. see also flex fuel vehicle (FFV)
|
| | |
| gasoline | common name for a refined hydrocarbon fuel - i.e. a mixture of flammable liquid hydrocarbons derived chiefly from crude petroleum and used principally as a fuel for internal-combustion engines. |
