Engineering microbes to produce biofuels

Population growth, finishing and wasting the energy sources, the contamination from the fossil fuels and finally the corruption in the environment are the factors which are alarming the limits the future of the human beings and also the underlying dangers. Considering the existing limits the only correct way is the right use of energy, optimization in the energy consuming appliances and using new returnable sources of energy in order to control the energy crisis. So using the new sources of energy instead of fossil fuels is obligatory. So the new sources of energy should rely on structural and fundamental changes in which the solar energy is used in them and using this source of energy is a based in this type of construction and sustainable architecture which can solve many of present problems of society in optimizing energy consumption. In this article we have worked on solar energy as a returnable source of energy in buildings and the relevant effects on energy consumption reduction and the effects on architecture stability.

With the modernization of the technology with time, the demand for energy is increasing day by day, it is necessary to find out the new sources of renewable energy. The fossil fuels upon which the maximum energy has been produced till date are going to be depleted soon. A triboelectric nanogenerator (TENG) is new source of energy firstly demonstrated by Wang et al. in 2012, working basically on the principles of triboelectric effect and electrostatic induction. A triboelectric nanogenerator (TENG) can be used to harvest many forms of energy from the environment which is generally wasted. It has a very simple working mechanism and easy design and can be used to power many small wearable electronics. Many properties of the TENG make it capable of producing large power, and to be used in future for large power generation.

Laser technology has been used in Urology since the 80s with a lot of different applications in endoscopic and open surgery. With the developments of the technology and the introduction of new active medium and source of laser energy, this technology have become the gold standard not only in stone surgery but even in benign prostate enlargement (BPE) surgical treatment. Regarding urologic oncology, laser energy has now reached an important role in focal therapy and in conservative treatment. The possibility of having better functional outcomes without any relevant impact on oncological results led to an increased use of laser in penile surgery, with a significant mention in urological guidelines for this option. In urothelial cancers as well, both in conservative management of upper tract tumors that in the treatment of non muscle invasive bladder cancer, a clear role of these relatively new source of energy have been demonstrated. Finally, both in prostate that in renal cancer the strategy of focal therapy may take advantage from this precise and fine technology. In this review we analyzed and described the applications of laser energy in urological cancers with a specific focus on penile, urothelial and prostate cancer.

Most Malaysian jacket platforms have outlived their design life. As these old platforms have outlived their design life, other alternatives must be considered. As several offshore oil and gas extraction installations approach the end of their operational life, many options such as decommissioning and the development of a new source of energy such as wind farms are introduced. The objective of this paper is to investigate the environmental impacts of utilising ageing fixed offshore platform as a source for Ocean Thermal Energy Conversion (OTEC). The environmental impact of utilising an ageing fixed offshore platform as an OTEC source is discussed. OTEC produces energy by taking advantage of temperature variations between the ocean surface water and the colder deep water through cold-water intake piping, which requires a seawater depth of 700 metres. The output of this study shows that OTEC is envisioned to preserve marine life, becoming a new and reliable source of energy, assist clean water production, and reduce the negative impact of climate change. OTEC platforms utilising ageing platforms may lead to 44 % of fish catch in the ocean, remove 13 GW of surface ocean heat for every GW of electricity production per year, generate 1.3105 tonnes of hydrogen per year for each GW of electricity generated. In addition, OTEC platforms can reduce approximately 5106 tonnes of carbon dioxide from the environment for 1 GW of electricity generated per year, and supply 2 million litres of water per day for a 1 MW platform. Since Malaysia’s seawater profile allows for installing a fixed offshore platform as an OTEC power plant, Malaysia has many potentials to profit from the OTEC process.

Since the last decade of the twentieth century, systems biology has gained the ability to study the structure and function of genome-scale metabolic networks. These are systems of hundreds to thousands of chemical reactions that sustain life. Most of these reactions are catalyzed by enzymes which are encoded by genes. A metabolic network extracts chemical elements and energy from the environment, and converts them into forms that the organism can use. The function of a whole metabolic network constrains evolutionary changes in its parts. I will discuss here three classes of such changes, and how they are constrained by the function of the whole. These are the accumulation of amino acid changes in enzyme-coding genes, duplication of enzyme-coding genes, and changes in the regulation of enzymes. Conversely, evolutionary change in network parts can alter the function of the whole network. I will discuss here two such changes, namely the elimination of reactions from a metabolic network through loss of function mutations in enzyme-coding genes, and the addition of metabolic reactions, for example through mechanisms such as horizontal gene transfer. Reaction addition also provides a window into the evolution of metabolic innovations, the ability of a metabolism to sustain life on new sources of energy and of chemical elements.

Until now, most national and international institutions related to PV and, in general, to solar energy, focused their attention on demonstration and pilot projects which, in developing countries, often have had little or no impact on bringing new sources of energy into widespread use. This situation led some researchers and policy makers to imagine new schemes for the dissemination of new and renewable sources of energy (NRSE). Appearing particularly promising, the implementation of Regional Centers which, much with the same philosophy as the International Agricultural Research centers (CGIAR), may constitute an important thrust to the use of NRSE. Detailed considerations of the primary tasks, as well as, the financial requirements of such Regional Centers are presented and discussed.

As the energy sources decrease and the climate conditions change, demand for new and clean sources of energy has increased (Hong et al., 2009; Li et al., 2010a). Fuel cells , as a high efficiency energy converting device, have attracted more and more attention recently with low/zero emission (Liu et al., 2006). Moreover, conventional sewage treatment requires high energy and capital cost so there is great interest for finding clean and sustainable energy with very low or zero emission and cost effective that is an alternative for treatment technology (Appleby, 1988; Min et al., 2005). Microbial fuel cells (MFCs) are one kind of fuel cell and also new source of energy. In MFCs, electrons are supplied from chemical bonds with the aids of microorganisms. Then the produced electrons are transported to anode surfaces and protons are moved through proton exchange membrane or salt bridge toward cathode (Wen et al., 2009). The electron flows through an electrical external circuit while anode is connected to cathode. The flow of electron has a current (I) and power (P) is resulted. The reduction of organic substances in anode was catalyzed by the living organism in anode chamber (Chen et al., 2008; Rahimnejad et al., 2009) Traditional MFC is consist of two separated chambers named cathode and anode ones. Oxidation of substrate by microorganisms leads to generation of electrons and protons in anaerobic anode compartment. (Rahimnejad et al., 2009). A typical biological fuel cell is shown schematically in Fig.1. Several parameters affect on the performance of MFC, namely microbial inoculums, chemical substrates, mass transfer area, absence or existence of proton exchange materials, mechanism of electron transfer to the anode surface ,cell internal and external resistance, solution ionic strength, electrode materials and the electrode spacing (Park and Zeikus, 2000; Gil et al., 2003; Rosenbaum et al., 2007; Zhang et al., 2007; Li et al., 2010b) Direct electron transfers from anaerobic anode chamber to anode surface had shown to take place only at very low efficiency (Park et al., 2000; Lovley, 2006) . Electron transfer efficiencies in MFCs would be improved with the use of suitable electron mediators. Most MFCs use electron mediator component to improve the output of the cells. It has been reported in the literature that mediators are artificially added to anode chamber, such as Methylen blue (MB), Neutral red (NR), Thionin, Ferricyanide, Humic acid or Methyl viologen (Kim and Lee). The presence of artificial electron mediators are essential in some of MFCs to improve the performance of MFCs (Park and Zeikus, 1999; 2000) . But recently,

Prospects for new sources of energy: A report on the United Nations Conference on New and Renewable Sources of Energy, Nairobi, Kenya, 10?21 August 1981

The psychological effect of colors is one of the most important studies that scholars interested in contemporary history, and they divided the colors into color groups according to this thermodynamic effect, so there were hot colors, warm colors, cold colors and moderate colors, and research thought has always focused in this field on that this The color thermal effect is a psychological psychological effect only, and that a person’s feeling of heat when he is in a colored space with red tones, for example, is only a psychological feeling and feeling, but we in this research try to prove that this thermal effect of color is a real physiological effect It has scientific evidence and support, and real physiological reasons, and that this thermal energy inherent in the colors we must take advantage of to create the thermal environment of the residence, that the selection of the color group chosen to cover the internal voids of the housing is selected according to the thermal energy that can be obtained from these colors, so we save a lot Of the energy wasted in using the thermal setting means for the house, we try in this research to prove that it is possible to get a feeling of thermal hot or cold or moderate inside the house by using the color thermal energy without the need to use means of heating or cooling with Hzh the price, only the motives of changing color selection group used in the house according to the desire of the good guys and personal whims and desires, but be aimed at achieving an appropriate thermal environment, in addition to satisfying personal taste and aesthetic considerations. Obtaining new sources of energy is now the primary concern of scientists around the world from the multiple miracles of God Almighty that He put in the colors that it can achieve a feeling of cold or heat when seen by the person living in the place, and we must pay attention to the fact that the color levels are related Closely related to the degree of thermal feeling, and that, God willing, we can control the thermal feeling index in the house by controlling the proportions and degrees of the color group chosen for the different housing spheres, and by this we will be able to obtain a new, continuous and inexpensive source of energy. The connection between light and color is close (without the light we have not seen color and the color is an essential component of light), light rays are moving colored photons, and this movement is in the form of rays or waves that meet in a bundle that takes white color, which is shown by the explanatory analysis For the components of visible light trapped between the photons of ultraviolet and infrared, as for photons of ultraviolet or infrared, the human eye is not equipped to see it or see what is happening in these two regions, as if not for the light and the moving photons in the optical beams we would not be able to see static atoms The colored constituent elements of life around us. The thermal feeling that arises from the close relationship between (photons of light and color atoms and cells of the human body) is very important, and the discovery of the energy inherent in this active relationship between the moving color photons that make up the light and static colored atoms that make up the solids around us and their thermal effect on the constituent elements of the human body cells It is an important source of human heat supply, due to its psychological and physiological thermal effect, and this effect and thermal feeling can be increased, decreased or moderate in the temperature of the interior space in the contemporary housing, .

Catalyst: Chemistry’s Role in Providing Clean and Affordable Energy for All

Biofuels

Depletion of easily accessible petroleum reserves has created unstable oil supply and price, opening the opportunity to replace oil as an energy source with other fossil sources and ultimately with renewable and perhaps nuclear sources. The dual-fuel strategy is a plan to facilitate the transition from fossil to renewable sources by first replacing fossil with renewable fuels. It stipulates that all energy sources (fossil, renewable, and nuclear) will be most efficiently monetized by conversion to three primary energy vectors: electric power and two liquid renewable fuels, all compatible with existing infrastructure. One member of a dual-fuel pair is nitrogen-based, for example, ammonia, and the other is carbon-based, for example, methanol. The two are complementary: ammonia is carbon-free, but has high relative toxicity, while methanol has low relative toxicity, but contains carbon. Unlike hydrogen (a gas), these liquid fuels are compatible with existing infrastructure with only modest modification. Alternatives to ammonia are liquid ammoniates; alternatives to methanol include ethanol, dimethyl ether, and higher alcohols, and alkanes. The two renewable fuels may be called nitrofuel and carbofuel to avoid prejudice as to their exact composition. Renewable fuels are derived from air, and because nitrogen is 2000 times more abundant in air than is carbon dioxide, nitrofuel will be most efficiently produced and at least cost; it will therefore be used whenever possible. In some applications, however, the additional cost of producing carbon-based fuel will be justified by ease of handling. A small number of applications require high energy density fuel; these will be served by a secondary carbon-based fuel vector, derived from primary carbofuel at further cost. The dual-fuel strategy is market-driven. It identifies the sources of competitive advantage for renewable fuels and relies on the force of free enterprise to create a postpetroleum civilization powered by a zero-net-carbon energy system. The strategy enables global carbon emissions to be reduced significantly early in the transition, perhaps by as much as an order of magnitude by 2030, with zero-emissions perhaps as early as 2050.

The Energy Problem in this country today is a very complex issue which underlies many facets of the operation of our entire society. Energy is the source of this nation's economic growth … that growth over the past decades has been very rapid, and as a consequence, our ability to supply new sources of energy ‐ ‐ growing sources of energy ‐ ‐ has not been able to keep pace with the demand. At this time, there is a very broad spectrum of research programs underway, both supported by the Federal government and by private industry. The three main targets for these research areas are to increase energy supply, to control energy demand, and to improve energy utilization, particularly in minimizing the effect of energy utilization on health and on the environment. A brief overview of the role of R & D in the evolving energy posture of the United States is presented. Among the topics discussed are: ○The present funding situation in Federal and private sector energy R & D, ○The present and evolving role of Federal...

Due to the rapid industrialization and luxurious life style of mankind all of the non renewable sources of energy are going to finish in near future. To address energy crisis problem it is necessary to search or invent long lasting new sources of energy which could run the world for long term. Here, in this article a attempt has been made to discuss a new source of energy called nuclear fusion process. Several methods made to produce energy from nuclear fusion process are tried to discuss here. Fusion power offers the prospect of an almost inexhaustible source of energy for future generations, but it also presents so far insurmountable scientific and engineering challenges. The main hope is centered on tokamak reactors which confine deuterium-tritium plasma magnetically. The Himalayan Physics Year 5, Vol. 5, Kartik 2071 (Nov 2014)Page: 131-136
