Summary of "Bioelectrochemical systems: Sustainable bio-energy powerhouses."

Bioelectrochemical systems comprise of several types of cells, from basic microbial fuel cells (MFC) to photosynthetic MFCs and from plant MFCs to biophotovoltaics. All these cells employ bio entities at anode to produce bioenergy by catalysing organic substrates while some systems convert solar irradiation to energy. The current review epitomizes the above-mentioned fuel cell systems and elucidates their electrical performances. Microbial fuel cells have advantages over conventional fuel cells in terms of being sustainable whilst producing impressive power efficiencies without any net carbon emissions. They can be utilized for several environmentally friendly applications including wastewater treatment and bio-hydrogen generation, apart from producing clean and green electricity. Multifarious heterotrophic and autotrophic microbes and plants have been studied for their potential as imperative components of fuel cell technology. MFCs also display some interesting applications, such as integration of plant MFCs into architecture to produce "green" cities. Biophotovoltaic technology is the current hot cake in this field, which aspires to achieve significant electrical efficiencies by light-induced water splitting mechanisms. Furthermore, the utilization of BPVs in space renders it a technology for the future. Compared with other fuel cell systems, this technology is still in its inception and requires further efforts to endeavour its use on commercial or industrial level.

Medical and Biotech [MESH] Definitions

Electric power supply devices which convert biological energy, such as chemical energy of metabolism or mechanical energy of periodic movements, into electrical energy.

The transfer of energy of a given form among different scales of motion. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed). It includes the transfer of kinetic energy and the transfer of chemical energy. The transfer of chemical energy from one molecule to another depends on proximity of molecules so it is often used as in techniques to measure distance such as the use of FORSTER RESONANCE ENERGY TRANSFER.

Achievement of an economic system that can continue to grow for the foreseeable future.

A technique for analysis of the chemical composition of molecules. A substance is bombarded with monochromatic ELECTRONS. Some of the electrons passing through the specimen will lose energy when they ionize inner shell electrons of the atoms in the specimen. The energy loss is element dependent. Analysis of the energy loss spectrum reveals the elemental composition of a specimen. ENERGY-FILTERED TRANSMISSION ELECTRON MICROSCOPY is a type of electron energy loss spectroscopy carried out in electron microscopes specially outfitted to analyze the spectrum of electron energy loss.

Thermal energy contained in the earth. It can be used directly to supply heat or converted to mechanical or electrical energy. (from McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
