TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Cells: The cells express the heterologous TE-II and the FAS lacking a TE-I domain, but not the heterologous FAS. The cells express the heterologous TE-II and the heterologous FAS, but not the FAS lacking a TE-I domain. The genetically modified cells comprise (a) DNA sequences encoding the heterologous TE-II and the heterologous animal FAS or the heterologous animal FAS lacking a TE-I domain on an expression vector or (b) DNA sequences encoding the heterologous TE-II and the heterologous animal FAS or the heterologous animal FAS lacking a TE-I domain integrated into nuclear DNA or organelle DNA of the genetically modified cells, where the genetically modified cells are eukaryotic cells, prokaryotic cells or algae. The eukaryotic cells are yeast cells, and prokaryotic cells are bacteria. The algae comprise DNA sequences encoding the heterologous TE-II and the heterologous animal FAS or the heterologous animal FAS lacking a TE-I integrated into chloroplast DNA. The algae are maintained in the media in a photobioreactor or pond.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The amount of 4-14C fatty acids extracted from the cells and/or the medium is a greater percentage of total fatty acids as compared to 4-14C fatty acids measured as a percentage of total fatty acids produced by control cells that do not comprise a heterologous animal TE-II, a heterologous animal FAS, or a FAS lacking a TE-I domain. The fatty acids extracted from the cells and/or the media comprise 4-14C fatty acids, where the 4-14C fatty acids are at least 5% of total fatty acids extracted from the cells and/or the media. The 4-14C fatty acids are at least 10% of total fatty acids extracted from the cells and/or the media. The method further involves converting one or more of the fatty acids extracted from the cells and/or the media to an alcohol. The method further involves combusting the fatty acids extracted from the cells and/or the media to provide power to a machine, and further involves combusting the alcohol to provide power to a machine.
