 | Motivated by non-renewable petroleum consumption and the perceived climate change due to carbon dioxide (CO2) and other greenhouse gases, effort has been focused on recuperating lost energy from hot exhaust gases. Automobiles using thermoelectric generators (TEGs) are possible solutions due to the potential for high regenerative rates associated with the amount of waste heat and the corresponding high temperature. TEGs are solid-state heat engines that contain no moving parts, and ... |

|
| Nigeria has an electricity problem. Decades of neglect and mismanagement have left the nation with an anemic electrical power grid, one that is utterly incapable of powering the modern economy of Nigeria's aspirations. Recognizing that solving Nigeria's electricity woes are foundational to achieving the Nigeria Vision 20: 2020 socio-economic development goals, the Goodluck Jonathan administration has put electrical power sector reform among its highest priorities. The administration's ambitious reform plan ... |

| Nigeria has long recognized the need to support entrepreneurial business growth to reduce its severe levels of poverty and improve socioeconomic stability. Attempts to provide this support have been largely ineffective, due in large part to the poor state of Nigerian electrical power infrastructure. In 2010, Nigeria renewed its emphasis on improving its power sector, including privatization of the formerly state-run system, but this plan requires several adjustments to optimize ... |

| Military missions often require the transport of fuel, such as diesel, to military bases in remote locations. The delivery of such flammable fuels is very expensive and dangerous, particularly in hostile environments. An ideal fuel source for military missions would be non-flammable, renewable, and readily available. Microbial fuel cells (MFCs) are a new technology in which microbes convert organic compounds (sugars, alcohols, complex wastes) directly into electrical power. Microbial catalysis ... |
