Endogenous electric currents generated instantly at skin wounds direct migration of epithelial cells and are likely to be important in wound healing. Migration of fibroblasts is critical in wound healing. It remains unclear how wound electric fields guide migration of dermal fibroblasts. We report here that mouse skin wounds generated endogenous electric currents for many hours. Human dermal fibroblasts of both primary and cell-line cultures migrated directionally but slowly toward the anode in an electric field of 50-100 mV mm−1. This is different from keratinocytes, which migrate quickly to the cathode. It took more than 1 hour for dermal fibroblasts to manifest detectable directional migration. Larger field strength (400 mV mm−1) was required to induce directional migration within 1 hour after onset of the field. Phosphatidylinositol-3-OH kinase (PI3 kinase) mediates cathode-directed migration of keratinocytes. We tested the role of PI3 kinase in anode-directed migration of fibroblasts. ...
The penetration of other sources of electricity such as renewables for example solar and wind, could also have contributed to a decline in electricity demand from Eskom. In addition, because of the lack of capacity in the generation of electricity experienced by Eskom in 2007 (Inglesi & Pouris 2010), some companies and households had to find other sources of electricity, which would have resulted in a decline in electricity demand from Eskom. Unfortunately, the actual size of the electricity demand market is still unknown because of the unavailability of certain types of data, such as renewable energy and other forms of electricity generation. The combined effect of all these changes in the demography, economy and usage patterns can be investigated using historical patterns, but contribute to uncertainties when trying to forecast future electricity demand.. Uncertainties occur in estimation, prediction or in forecasting. When statisticians develop predictions (forecasts) for an uncertain future, ...
In this investigation the electricity generation and the electricity capacity of energy mix for sub Saharan Africa from 2020 to 2040 including CO2 emission from (coal, oil, gas) (Total Final Consumption, transport) and power generation were analyzed. These energy sources include conventional and renewable energy sources such as coal, oil, gas, hydro, nuclear, bioenergy, solar PV, and other renewables. We developed a linear regression equation based on the least-square method of estimation to forecast the value of energy and CO2 emission. We fit a linear trend to the energy time series including CO2 emission to show how simple linear regression analysis can be used to forecast future value. The predicted results from 2020 to 2040 show that the electricity capacity and the electricity generation from gas, hydro, solar PV and other renewables will dominate compared to nuclear and bioenergy. Some forms of energies contributions such as nuclear and bioenergy will remain insignificant. The gas will
Electricity demand varies daily, weekly, and seasonally. The cost and price of electricity to meet the peak demands can be an order of magnitude greater or more than the cost and price of electricity at times of minimum demand. Nuclear systems are capital intensive, with low operating costs relative to those for most other methods used to produce electricity; thus, nuclear energy is most competitive in the production of base-load electricity (i.e., that part of the electricity demand that is constant throughout the year). Nuclear energy is generally not competitive for the production of intermediate and peak electricity, where the power plant operates for only a fraction of the year. Two nuclear hydrogen technologies (hydrogen produced using the energy from a nuclear reactor) have the potential to ?convert? peak electricity demand into ?base-load? demand and thus expand the markets in which nuclear energy is competitive. The production of hydrogen by electrolysis for industrial markets at times ...

Naturally-occurring endogenous electric fields (EFs) have been detected at skin wounds damaged tissue sites and vasculature. cells also align and elongate in an EF. Inhibition of vascular endothelial growth factor (VEGF) receptor signalling completely abolished the EF-induced directional migration of the progenitor cells. We conclude that EFs TC-H 106 are an effective signal that guides EPC migration through VEGF receptor signalling and genetic studies with mouse models. Progenitor cell marker CD133 and endothelial cell markers VEGFR-2 and von Willebrand Factor (vWF) were TC-H 106 used to confirm the endothelial progenitor cell nature. These combined proteins are the markers used to identify EPCs. We confirmed that the three cell lines (MFLM-4 AEL-deltaR1 and AEL-deltaR1/Runx1) are all positive with specific stem cell marker-CD133 and endothelial cell markers-vWF and VEGFR-2 (Fig. 1). Figure 1 Expression of progenitor markers 2.2 Directed migration of the progenitor cells by EFs MFLM-4 cells ...

TY - JOUR. T1 - Electricity awareness and consumer demand for information. AU - Trotta, Gianluca. PY - 2020/7. Y1 - 2020/7. N2 - With the envisioned growth in the residential electricity demand and increased share of intermittent renewables in the supply mix, consumers will need to be better informed about their electricity consumption and to play an active role in managing their electricity use. However, consumer inattention and lack of information are ubiquitous, especially in household energy‐related settings. Thus, by using a novel survey and actual monthly electricity consumption data, this study set out to measure the level of awareness about electricity bills, prices, and costs among some Finnish households - as captured by the answers to six questions - and to investigate whether higher levels of electricity awareness are associated with electricity savings. In addition, this study analyzes the willingness to receive extra information about energy consumption and savings and how it ...
Today ClimateXChange publishes some analysis Ive done with Keith Bell on security of electricity supply and how we can meet peak electricity demand in Scotland today and throughout the 2020s. Over the coming years we can expect significant changes to the Scottish electricity generation mix with growing renewable penetration and closure of Scotlands existing large power stations. The report shows that, without new schedulable generation capacity in Scotland following the closures of Hunterston and Torness, we will need new capability to import electricity into Scotland at certain times. Ensuring that our future electricity system can meet future demand means we need to think soon about how the electricity system should develop.. The ClimateXChange blog post.

More Videos, Visit : Introduction to basics of electricity and laws of magnetism. This animation science video on transmission of current (electricity) could be an excellent working science model or school project for children.Electricity is related to charges, and both electrons and protons carry a charge. The amount of the charge is the same for each particle, but opposite in sign. Electrons carry a negative charge while protons carry positive charge. The protons are located in the center of the atom, concentrated in a small area called the nucleus. The electrons are in motion outside of the nucleus in orbitals. The protons are basically trapped inside the nucleus and cant escape the nucleus. As a result, it is moving electrons that are primarily responsible for electricity.

TY - JOUR. T1 - Directing migration of endothelial progenitor cells with applied DC electric fields. AU - Zhao, Zhiqiang. AU - Qin, Lu. AU - Reid, Brian. AU - Pu, Jin. AU - Hara, Takahiko. AU - Zhao, Min. PY - 2012/1. Y1 - 2012/1. N2 - Naturally-occurring, endogenous electric fields (EFs) have been detected at skin wounds, damaged tissue sites and vasculature. Applied EFs guide migration of many types of cells, including endothelial cells to migrate directionally. Homing of endothelial progenitor cells (EPCs) to an injury site is important for repair of vasculature and also for angiogenesis. However, it has not been reported whether EPCs respond to applied EFs. Aiming to explore the possibility to use electric stimulation to regulate the progenitor cells and angiogenesis, we tested the effects of direct-current (DC) EFs on EPCs. We first used immunofluorescence to confirm the expression of endothelial progenitor markers in three lines of EPCs. We then cultured the progenitor cells in EFs. Using ...

Downloadable (with restrictions)! A combined gas and electricity network expansion planning model was developed. Gas-fired generation plants were considered as linkages between the two networks. The model simultaneously minimises gas and electricity operational and network expansion costs. Additionally it optimally places planned power generation plants around the electricity network. Network expansion was implemented by adding new assets such as pipes, compressors, and storage facilities in the gas network and increasing transmission line capacity in the electricity network. The developed model was used to analyse the GB gas and electricity infrastructure expansion requirements to achieve a low carbon energy system. Two scenarios were implemented, a reference and a low carbon scenario. For both scenarios, CGEN defined a network at lowest cost capable of meeting varying demand and power generation capacity profiles. Greater peak gas demand of approximately 25mcm/d by 2030 in the reference scenario
Spanish multinational corporation Abengoa has secured a contract worth about €1bn from the Brazilian National Electricity Agency (ANEEL) to construct new electricity transmission projects in the country..

by Christine Hertzog , Jan 30, 2012 , Blog site. One of the largest US-based industry conferences for electricity, gas, and water utilities just wrapped up in San Antonio, Texas. The entire value chain for electricity was well-represented there - you could find products for generation, transmission, distribution, and consumption of electricity. These products modernize the grid - making it the Smart Grid. The profusion of products prompted me to think about what really drives innovation in the electricity value chain. In Silicon Valley, entrepreneurs know that successful new products or services have to be painkillers or vitamins. As a painkiller, an innovation has to resolve a pain for its target audience. If its a vitamin, an innovative product or service has to improve an existing situation. Otherwise, theres just no motivation or incentive for a consumer or organization to adopt that innovation. And in a down economy, its all about painkillers. So what are the pains in the electricity ...

Classical univariate and multivariate time series models have problems to deal with the high variability of hourly electricity spot prices. We propose to model alternatively the daily mean electricity supply functions using a dynamic factor model. And to derive, subsequently, the hourly electricity spot prices by the evaluation of the estimated supply functions at the corresponding hourly values of demand for electricity. Supply functions are price (EUR/MWh) functions, that increase monotonically with demand for electricity (MW). Apart from this new conceptual approach, that allows us to represent the auction design of energy exchanges in a most natural way, our main contribution is an extraordinary simple algorithm to estimate the factor structure of the dynamic factor model. We decompose the time series into a functional spherical component and an univariate scaling component. The elements of the spherical component are all standardized having unit size such that we can robustly estimate the ...
Natural News) Bitcoins ongoing meteoric price rise has received the bulk of recent press attention with a lot of discussion around whether or not its a bubble waiting to burst.. (Article republished from PowerCompare.co.uk). However, most the coverage has missed out one of the more interesting and unintended consequences of this price increase. That is the surge in global electricity consumption used to mine more Bitcoins.. According to Digiconomists Bitcoin Energy Consumption Index, as of Monday November 20th, 2017 Bitcoins current estimated annual electricity consumption stands at 29.05TWh.. Thats the equivalent of 0.13% of total global electricity consumption. While that may not sound like a lot, it means Bitcoin mining is now using more electricity than 159 individual countries (as you can see from the map above). More than Ireland or Nigeria.. If Bitcoin miners were a country theyd rank 61st in the world in terms of electricity consumption.. Here are a few other interesting facts ...
The station can also produce, in addition to treated water, seven megawatts of electricity a day to run it. This means the municipality will also be able to save 1000 euros a day in electricity it would have bought from Israel to run the plant.. Plant manager and head of German projects in Nablus, Suleiman Abu Ghoush, told WAFA that the idea of producing electricity from methane gas was not there at the start of the project. However, after it was realized that the quantity of methane gas that will be produced would be enough to generate electricity that will run the station, it was decided to go ahead with it.. He said the station was a success story for the municipality since it became a permanent source of alternative energy that depends on waste-water and sewage.. With the success of this project, the Nablus municipality plans to build another treatment plant on the other side of the city that will also be able to generate enough electricity and water to serve the citys residents..

As of late, consumers and companies place emphasized importance on products and services sustainability, but one point worth contemplating is how to manifest sustainability in concrete, realistic terms. All products, bar inherently disposable ones, require inspection, maintenance, and repair. This of course means that cars, elevators, traffic signals, and all variety of devices intertwined in peoples everyday lives receive regular checks. The same concept applies to electricity, a fundamental element of daily life; electric generators, which create electricity, similarly require periodic maintenance. But generators are not only incredibly sophisticated, they can be huge vast and loaded with state-of-the-art-technology - and with all factors considered, conducting an inspection of the device can consume exorbitant amounts of time.. One example can be seen in the realm of thermal power, which accounts for over 60% of all electricity generated in Japan. Thermal power makes use of a massive ...
TY - JOUR. T1 - DC electric stimulation upregulates angiogenic factors in endothelial cells through activation of VEGF receptors. AU - Bai, Huai. AU - Forrester, John V.. AU - Zhao, Min. PY - 2011/7. Y1 - 2011/7. N2 - Small direct current (DC) electric fields direct some important angiogenic responses of vascular endothelial cells. Those responses indicate promising use of electric fields to modulate angiogenesis. We sought to determine the regulation of electric fields on transcription and expression of a serial of import angiogenic factors by endothelial cells themselves.Using semi-quantitative PCR and ELISA we found that electric stimulation upregulates the levels of mRNAs and proteins of a number of angiogenic proteins, most importantly VEGF165, VEGF121 and IL-8 in human endothelial cells. The up-regulation of mRNA levels might be specific, as the mRNA encoding bFGF, TGF-beta and eNOS are not affected by DC electric stimulation at 24. h time-point. Inhibition of VEGF receptor (VEGFR1 or ...
A Clark School of Engineering alum has transferred his Ph.D. research on the bioelectric effect into a pioneering consumer product that improves mouth and gum health. Young Wook Kim (ECE Ph.D. 2014) is the founder of ProxiHealthcare Inc., which manufactures the new TROMATZ toothbrush. First available in South Korea, the toothbrush employs the bioelectric effect to effectively attack the mouths plaque and tartar biofilms. It has received FDA and FCC approval in the United States and is available for purchase on Amazon.. Bacterial biofilms form in a variety of moist, inaccessible environments-like the mouth-where bacteria can adhere to complex curved surfaces like teeth. Given a little time, bacteria encase themselves in an extracellular matrix, forming biofilm. This matrix offers the bacteria significant protection and makes it easy for them to spread.. Dental plaque, and its hardened state, tartar, are types of biofilm. Left unchecked, plaque and tartar contribute to bad breath, gum disease, ...

Due to the security of supply and the connection with the European market, electricity networks will always be necessary says Meeuwsen. Further, due to an increasing demand for electricity it is important to include all possible energy options (including coal and nuclear energy) in the scenario development. The exact form of future networks will largely depend on the primary energy mix chosen. In all cases engineers face new and considerable challenges in the areas of network and system integration and the development and implementation of new technology. Moreover, in all scenarios the total network capacity must increase. Small-scale networks will adapt characteristics from the current large-scale networks, such as the possibility of two-way traffic and the responsibility to maintain a stable system.. Demand follows supply. In particular, the number of ways in which the total electricity supply system can be held in balance in the future will need to be expanded as more electricity is ...
The AEMC today made a final rule on new obligations on network businesses to provide more information on their plans for retirement and replacement of electricity network assets.. As the technology-driven transformation of the electricity market continues, there is now a greater focus on managing the existing electricity network in new ways. For example, developments in battery storage, demand response and other technologies may provide alternatives to poles and wires when parts of the network need to be replaced.. Taking account of these changes, the rule extends some of the mechanisms and planning arrangements in the rules to provide better information and more transparency on upcoming network replacement projects.. Under the rule, transmission and distribution network businesses would be required to include information on plans to retire electricity network assets or reduce their capability (known as de-rating) in their annual planning reports. The rule also extends the application of ...
Downloadable (with restrictions)! This paper presents evidence on a national-level electricity ladder which sees countries transition toward coal and natural gas, and finally nuclear power and modern renewables such as wind power, for their electricity needs as they develop. The extent to which countries climb the electricity ladder is dependent on energy endowments. The results imply that the environmental implications of economic development differ in countries with different energy resource endowments. An effective global carbon mitigation strategy will require developing countries to leapfrog the middle rungs of the electricity ladder.
Maria Wist Langmoen Own-price and income elasticities for household electricity demand -A Literature survey using meta-regression analysis. Economists have been modelling the electricity demand for several decades in order to explore the effect of governments taxation policies, to predict future demand and reveal needs for investment, and see the effect of price fluctuations on the demand. There is a wide range of studies to be found in the area, both because electricity demand can easily be measured, the interesting particularities of this demand and the practical importance of the results. The problem is that the results are not homogeneous. In the articles used for this review the income elasticities could be found in an interval of [0,04; 2,09], and own price elasticities [-0,91; 0,51]. When it comes to estimating effects of a new tax on the demand of electricity, the wide range of elasticity estimates will cause problems for policy makers that want to establish the effects the tax will have ...
Before electricity, this is the question!!!. An Electric Cosmos. A universe or many Universes formed from electricity. A natural cosmic energy. This opposes the big bang theory. However a big bang theory can be formed from an electric energy. Before the big bang theory. Electricity as the progenitor of the Universe and all other Universes. Lightening as energy/electricity, we know of, and understand lightening, observed in storms. Lightening is electricity. Everything has electricity. Electricity is the basic nature/structure, contained in all known and unknown existence, electricity is in all things/beings/matter/gasses/particles. Electricity was existing before our Universe was made. Electricity was existing before other Universes that are/were formed. Before the big bang theory, we observed dust and gasses, in a cloud/clouds, causing an explosion which formed the Solar System. However, it is also equally feasible, that an electric energy, itself, formed the Cloud, which formed the Solar ...
Effectively you buy electricity in kWh units. You choose how many units you buy and for what period. The price of the electricity varies, depending on how you buy it. For example, if you buy a bulk pack, you can typically get a cheaper per unit price than if you buy units in smaller bundles.. At the moment, with Southern Lakes brimming, prices are far cheaper than competing retailers. For example, the cheapest retailer that I could access in Wellington was charging 21.6 c/kWh (taking into account their discount), as well as a daily rate of around 80 c/day. Compare this to Powershop, where I have been buying electricity at around 18-19c/kWh, without any daily charge, and you can see the potential for savings.. The obvious risk from buying through Powershop is hydrological. Meridian (currently the only major retailer on Powershop) generates the vast majority of their electricity through South Island hydro generation. If there was a dry winter, I imagine that prices over this period would be ...

The Australian Energy Market Commission (AEMC) today released its 2014 Residential Electricity Price Trends report on factors driving electricity prices in each state and territory, which shows prices are mostly flat or falling.. The report analyses trends in the competitive market sectors of the electricity industry, the regulated networks sector, and resulting from government environmental policies. The factors driving each of the three are different, so understanding price trends involves looking into each individually.. The cost of supplying electricity has already fallen in 2014/15 following removal of the carbon price and is expected to remain stable over the following two years, although trends vary across the states and territories due to local factors.. AEMC Chairman John Pierce said the cost of poles and wires, which had previously led to significant price growth, was now expected to moderate under new rules introduced by the Commission.. The cost of the regulated network sector is ...

The electricity certificate is a market-based support system for renewable electricity production. The system came into force on 1 May 2003 and is intended to increase the production of renewable electricity and to make the production more cost-efficient.. For each MWh produced from renewable resources, electricity producers have the opportunity to be granted an electricity certificate by the Government. The certificates can be sold on an open market to electricity consumers - mostly via electricity suppliers - who have to fulfil a quota obligation of certificated electricity. The quota is set in proportion to total electricity use. Energy-intensive industry is exempt from the requirement. The demand is thus regulated by means of the quota, while the supply is unregulated. The price is determined freely on the market for certificates. Only new power plants or plants which have undergone recent significant changes are entitled to certificates.. The renewable energy sources include wind, solar, ...

The use of such granular data will be useful for planners, regulators, and researchers going beyond measuring generation on a daily basis.. ...
This simple light detector approach works particularly well in homes where the householder is out all day since once the baseline electricity needs of the home are met, the surplus electricity can be used for free water heating instead of being exported (which would earn just a few pennies per kWh unit of electricity exported).. However, this system is not a true surplus electricity controller since if the home owner has a 4 kW solar array, and a 3kW immersion element, then if more than 1kW of electricity is being used in the home on other things - e.g. kettle, washing machine, or other heavy loads, electricity will be imported at a cost to cover any shortfall.. This week we have been working on the next level approach which is very useful for some households depending on how their electricity meter(s) are set up. In our article Flashing LED on Electricity Meter we looked at how modern electricity meters are fitted with a red LED which flashes at a rate proportional to the power passing through ...

Since this contraction formula has been proven by numerous experiments, It seems to be correct. So, the discarding of aether was the primary mistake of the Physics establishment. Empty space is not empty. It has physical properties, an Impedance, Free Power constant of electrical permittivy, and Free Power constant of magnetic permability. Truely empty space would have no such properties! The Aether is seathing with energy.

Figure 5.6 shows that the introduction of renewable technologies under the Energy [R]evolution scenario increase the future costs of electricity generation compared to the Reference scenario until 2020. This difference will be less than 0.8 US$ct/kWh up to 2020, however. Because of high prices for conventional fuels and the lower CO2 intensity of electricity generation, from 2030 on electricity generation costs will become economically favourable under the Energy [R]evolution scenario and by 2050 costs will be 7.5 US$ct/kWh below those in the Reference version. Under the Reference scenario, on the other hand, unchecked growth in demand, an increase in fossil fuel prices and the cost of CO2 emissions result in total electricity supply costs rising from todays US$ 96 billion per year to more than US$ 555 billion in 2050, compared to US$ 327 billion in the Energy [R]evolution scenario. Figure 5.6 shows that the Energy [R]evolution scenario not only complies with the ASEAN regions CO2 reduction ...

In the quest for renewable energy some ideas are wackier than others.. This pee-powered toilet created by researchers at the University of the West of England (UWE Bristol) converts urine into electricity might just be crazy enough to work.. Professor Ioannis Ieropoulos, project leader and director of the universitys Bristol BioEnergy Center, said the urinal uses microbial fuel cell stacks to convert the urine into electricity that powers the restrooms electric lights.. We have already proved that this way of generating electricity works. Work by the Bristol BioEnergy Center hit the headlines in 2013 when the team demonstrated that electricity generated by microbial fuel cell stacks could power a mobile phone. This exciting project with Oxfam could have a huge impact in refugee camps, Ieropoulos said..

A lot of people around the world are convinced that solar energy is one of the best solutions to our current challenges in energy as well as in climate change. There may be various of reasons for different people why they go solar, but it all comes down to few reasons such as:. Lowers-down electricity bill. One of the few good reasons why a lot of people go solar is that it cuts-down electricity bill. Because the energy generated from the sun is totally free, you may convert as many appliances as possible to use this generated energy, and yet may still have significant savings in your electricity expenses. Use our solar power calculator to find out how much you can save from generating your own electricity.. A great source of renewable energy. The electricity that we mostly use today is typically generated from fossil fuel, which is sooner or later will eventually run out. Solar energy is a great alternative to replace this fossil fuel energy to renewable energy as the suns energy has no limit ...
TY - JOUR. T1 - Estimating the price elasticity of US electricity demand. AU - Smith, V. Kerry. PY - 1980/4. Y1 - 1980/4. N2 - The use of a single electricity price has been seen as a major shortcoming of econometric models of residential electricity demand. It has been suggested that demand estimation should be based on the full rate schedule. This suggestion is evaluated here by examining demand estimates for 27 investor-owned US utilities over the period 1957-1972. The specification errors resulting from using an average revenue price are measured. It is found that statistically valid demand estimated do not necessarily require information on tariff schedules, but that state-wide aggregates of elasticity may often be inapplicable to individual utilities.. AB - The use of a single electricity price has been seen as a major shortcoming of econometric models of residential electricity demand. It has been suggested that demand estimation should be based on the full rate schedule. This suggestion ...

Peat is also included in this category.This page has the latest values, historical data, forecasts, charts, statistics, an economic calendar and news for Electricity production from coal sources (kWh) in Angola.
The use of adsorption in Thermal Energy Storage has gained considerable research interest of late. Some applications have focused on the use of TES for transformation of low temperature heat in applications such as cooling and heating. Zeolite and water have been studied as suitable materials. Their characteristics as environmentally friendly materials and high affinity makes them conspicuous. The unique properties of zeolites to hold adsorbed water/heat with very minimal loss is also significant. With the aid of a dynamo, a Stirling engine as heat engine and the adsorption energy storage system serving as heat pump was used to generate electricity. The relationship between electricity generation and temperature was investigated. The obtained average temperature and pressure of the zeolite - water adsorption heat pump was also compared with the basic adsorption cycle ...
In January-August, Azerenergy (electricity generation and distribution in Azerbaijan) generated about 14.5 billion kilowatt-hours of electricity compared to about 13.2 billion kilowatt-hours during the same period of last year, Azerenergy said on Monday.
Another study investigated the contribution of direct electron transfer mechanism on electricity production by physically retaining Shewanella oneidensis cells close to or away from the anode electrode using a dialysis membrane (as well as immobilisation of the cells in alginate). Pyruvate was used as the substrate. The outcome of this study indicated a Pmax value of 114±6 mWm-2 when cells were retained close to the anode, 3.5 times more than when the cells were separated from the anode. Without the membrane Pmax was 129±6 mWm-2 (57% COD reduction ...
There is an urban advantage in Zimbabwes energy profile, as is the case across much of Africa. The overwhelming bulk of the regions electricity grid is concentrated in urban areas, while the vast majority of the population living without electricity is in the rural and peri-urban areas.. According to the Zimbabwe national energy policy report of 2012, 83% of urban households have access to electricity compared with 13% in rural areas. Rural communities meet 94% of their cooking energy requirements from traditional fuels, mainly fuelwood. Wood is the main cooking fuel for 20% of urban households.. No newer reliable data are available, but these trends are likely to have got worse rather than better in the past seven years.. Coal, charcoal and liquefied petroleum gas are used by less than 1% of urban households. The electrification rate in the rural areas is approximately 10%. Connection to the electricity grid is highly unequal.. Households poverty status adds to the disparity in access. A ...

Enhanced local electric fields are predominant in nonlinear optical properties, particularly in surface-enhanced Raman scattering (SERS), which is a sensitive technique used for the detection of trace amounts of chemicals. Analysis of the electric fields around nanostructures indicates that they can provide a basic foundation to obtain greater SERS intensity. Professor ZHANG Zhongyue and his group from the College of Physics and Information Technology at Shaanxi Normal University have proposed a novel scheme to enhance the local electric fields around nanostructures. The scheme is based on manipulation of the incident wave to allow the superposition of the electric fields of multiple beams of light to work as the excitation source for the electrons in the nanostructures, and larger electric fields are thus excited around the nanostructures. Their work, entitled Enhancing the electric fields around the nanorods by using metal grooves, was published in SCIENCE CHINA Physics, Mechanics & ...

30 mA can cause the onset of potentially fatal respiratory paralysis. The adverse effect will be directly related to the level of current, the length of time that the body is exposed and the path the current takes through the body.. Most of us have experienced some form of electric shock, where electricity causes our body to experience pain or trauma. If we are fortunate, the extent of that experience is limited to tingles or jolts of pain from static electricity build up, discharging through our bodies. When we are working around electric circuits, capable of delivering high power to loads, electric shock becomes a much more serious issue, and pain is the least significant result of shock.. As electric current is conducted through a material, any resistance (opposition to flow of electrons) results in a dissipation of energy, usually in the form of heat. This is the most basic and easy-to-understand effect of electricity on living tissue: current makes it heat up. If the amount of heat ...
Inefficient transmission and distribution (T&D) infrastructure that results in losses as electricity travels from supplier to customer contributes to compensatory power generation and therefore to unanticipated GHG emissions. Pilferage, poor planning and management in the T&D system also contribute to losses that can increase total electricity generation. Because the combination of electricity generation, combined heat and power generation and heat plants account for over 40% of global GHG emissions1, mitigation efforts tend to focus on electricity generated rather than delivered. We combine life cycle assessments of power generation with uncertainty analysis to bound potential emissions from compensatory generation from T&D aggregate losses (that is, technical and non-technical) in 142 countries. We estimate that electricity generated due to losses from T&D infrastructure is associated with nearly 1 billion metric tons of carbon dioxide equivalents per year (GtCO2e yr-1). Our global average estimates
I developed a Microbial Fuel Cell (MFC) that unprecedentedly works (i.e., produces electricity) under extreme salinity (≈ 100 g/L NaCl). Many industries, such as oil and gas extraction, generate hypersaline wastewaters with high organic strength, accounting for about 5% of worldwide generated effluents, which represent a major challenge for pollution control and resource recovery. This study assesses the potential for microbial fuel cells (MFCs) to treat such wastewaters and generate electricity under extreme saline conditions. Specifically, the focus is on the feasibility to treat hypersaline wastewater generated by the emerging unconventional oil and gas industry (hydraulic fracturing) and so, with mean salinity of 100 g/L NaCl (3-fold higher than sea water). The success of this novel technology strongly depends on finding a competent and resilient microbial community that can degrade the waste under extreme saline conditions and be able to use the anode as their terminal electron acceptor ...
Genesis (γενεσις) = growth. So the method is literally about using the biological effect of electricity to stimulate the growth of new hairs, and the primary application being targeted is male pattern baldness.. The devices that are being studied and developed come in various shapes and sizes, but what they have in common is they all come into contact with the scalp, where the electricity is applied directly. So, its a topical treatment.. So, how on earth does it work?. Now, if youre not familiar with the field of medical devices, this might seem a bit, well, odd.. Electricity is good for powering up the gadgets and appliances that we use daily, but as most of us have learned the hard way, when it comes into direct contact with our body it can be very nasty.. So, ETG is all about the voltage.. Now, in the US for example, the household voltage that powers your television and fridge is 110V. Touch a live cable at those voltages and youll be in trouble, no doubt about it.. But devices ...
As solar electricity is now about half the cost of power from the grid and is by far the cheapest source of electricity available to households, unless there is a very large drop in the cost of daytime grid electricity, we can expect rooftop solars rapid expansion to continue and result in a large decrease in Australias CO2 emissions. Personally, I am hoping solar will expand extremely rapidly, as I have had about all the global warming I can handle. The temperature for tomorrow here in Adelaide is forecast to be 44 degrees Celsius. Thats seven degrees above body temperature. If my air conditioner dies, I may die. So please, I beg you, consider installing a rooftop solar system no matter where you are. If not for my sake, then for all the people in India and Africa and other places who dont have air conditioning. ...
German industry releases 200 billion kilowatt-hours of thermal energy a year into the environment as unused waste heat - roughly equivalent to the entire energy consumption of the federal state of Hesse. In a new documentary by VDI ZRE entitled Stromerzeugung aus industrieller Abwärme (Generating Electricity from Industrial Waste Heat), two companies demonstrate how they use this valuable energy source to produce electricity, thereby making an important contribution to the conservation of resources.. BILSTEIN GmbH & CO. KG in North Rhine Westphalia processes steel strips for use in the furniture, tool and automotive industries. The strips have to be heated and then re-cooled so that they can later be formed and further processed. The waste heat generated in this recrystallisation process is used to produce electricity, with the aid of an innovative Organic Rankine Cycle (ORC) system. Unlike conventional procedures, ORC can make use of the relatively low temperatures of the waste heat for the ...

Scientists at the Bristol Robotics Laboratory, have demonstrated that a commercially available mobile phone can be charged and powered with urine.. The availability of energy for communication when in remote areas can be a big problem. If you could charge your phone with your own readily available urine, the worry of running out of phone battery in a difficult situation is solved. This research also opens up lots of possibilities for the utilisation of waste for useful energy. The authors of this research told UWE News that they think their technology could be installed into domestic bathrooms to harness the urine and produce sufficient electricity to power showers, lighting or razors as well as mobile phones.. Microbial Fuel Cells use live microorganisms to turn organic matter into electricity. The group created a membrane-less microbial fuel cell, which was made out of ceramic material and used carbon-based electrodes.. Read the story in UWE Bristol News here….

The Tricolor project wants to increase the use of biomass for sustainable heat or electricity production. At the core of the project are transnational networks through which experience and knowledge will be shared.. Today, the potential of the available bioenergy is not fully used, and the project argues that an increase would favor the climate and create job opportunities. Renewable energy is high on the European agenda and efficient use of woody biomass is a common strategic field of interest in the Baltic Sea region. During the last decades, the traditional use of wood for heating has developed in Sweden, Estonia and Ukraine. Despite this progress, some common challenges remain. They include energy wood supply, information support and business models in biomass and cooperation. To meet these challenges, channels for knowledge sharing and cooperation within the area must be developed.. The project aims to strengthen and expand an existing transnational network. The network will focus on ...
Germanys consumption of coal jumps in 2012. (Photo credit: Edal Anton Lefterov, Creative Commons Attribution-Share Alike 3.0 Unported license). The BDEW says the trend for renewable energies is positive. The share of electricity produced by renewable sources rose in 2012 to about 21.9% (2011: 20.3). However, the share of CO2-free nuclear energy fell from 17.7% to 16%. The drop in nuclear energy was partly offset by a rise in coal-fired electricity, meaning increased CO2 emissions. Black coals share of electricity jumped from 18.5% to 19.1%. The share of electricity from lignite-coal rose a full percent to 25.6%, thus making it Germanys largest source of electrical power.. Germanys use of coal has increased and thus has not gotten more green; it has gotten dirtier. Thats what we are getting for the tens of billions of euros in added electricity costs incurred from adding renewable energy capacity.. The share by relatively clean natural gas in electricity generation dropped from 13.6 to ...
In Line Signal Repeaters for Transmission Line Based Electric Fences - An electric repeater for use in transmission line based electric fences. The electric repeater comprises a forward amplifier, a backward amplifier, a quad pole quad throw signal switch, and a monostable circuit. The short forward electric pulse in the transmission line is amplified by the forward amplifier, and the amplified electric pulse trigger the monostable circuit. The monostable circuit then outputs a n electric pulse with predetermined width. This electric pulse operates the quad pole quad throw signal switch such that the wire pair of the transmission line is connected to the backward amplifier and disconnected from the forward amplifier as soon as the forward electric pulse has passed through the forward amplifier. DC electric power is supplied to the forward amplifier and backward amplifier by the transmission line metal wire pair, and two pairs of capacitors are used to block this DC electric power from entering ...
This research provides a systematic review and harmonization of the life cycle assessment (LCA) literature of electricity generated from conventionally produced natural gas. We focus on estimates of greenhouse gases (GHGs) emitted in the life cycle of electricity generation from natural gas-fired combustion turbine (NGCT) and combined-cycle (NGCC) systems. The smaller set of LCAs of liquefied natural gas power systems and natural gas plants with carbon capture and storage were also collected, but analyzed to a lesser extent. A meta-analytical process we term harmonization was employed to align several system boundaries and technical performance parameters to better allow for cross-study comparisons, with the aim of clarifying central tendency and reducing variability in estimates of life cycle GHG emissions.. Of over 250 references identified, 42 passed screens for technological relevance and study quality, providing a total of 69 estimates for NGCT and NGCC. Harmonization increased the median ...
The biocathodic reduction of nitrate in Microbial Fuel Cells (MFCs) is an alternative to remove nitrogen in low carbon to nitrogen wastewater and relies entirely on microbial activity. In this paper the community composition of denitrifiers in the cathode of a MFC is analysed in relation to added electron acceptors (nitrate and nitrite) and organic matter in the cathode. Nitrate reducers and nitrite reducers were highly affected by the operational conditions and displayed high diversity. The number of retrieved species-level Operational Taxonomic Units (OTUs) for narG, napA, nirS and nirK genes was 11, 10, 31 and 22, respectively. In contrast, nitrous oxide reducers remained virtually unchanged at all conditions. About 90% of the retrieved nosZ sequences grouped in a single OTU with a high similarity with Oligotropha carboxidovorans nosZ gene. nirS-containing denitrifiers were dominant at all conditions and accounted for a significant amount of the total bacterial density. Current production ...
The depletion of fossil fuel reserves, global warming, energy security and the need for clean, cheap fuels has made developing sources of renewable energy a global research priority. Microbial Fuel Cells (MFCs) have the potential to generate renewable electricity from a vast array of carbon sources such as waste-water, agricultural by-products and industrial pollutants. In MFCs electrons from microbial metabolism flow from the bacteria toward an anode then on through an external circuit finally converting oxygen into water at the cathode closing the cycle. The optimization of MFC systems is a highly multidisciplinary area of research and two complementary areas of work are required - firstly to design more efficient hardware for the cells by traditional engineering and secondly to understand and improve the interaction and electron transport between microbes and electrode via biological engineering. One of the most important engineering challenges in MFC development is the efficient electron ...

quantity of positive, and potassium of negative electricity. Bodies lying between these two extremes contain a larger quantity of heat with a smaller excess of one or the other kind of electricity, the proportion of which varies greatly according to their nature,-and thus form an electrical series which perhaps coincides with the column of affinity of oxygen (p. 144).. The combination of two ponderable bodies is the result of two forces, viz., the affinity of the ponderable bodies for each other, and the affinity of the electricity which is in excess in the one body for the opposite electricity which predominates in the other. By these two forces the affinity of the electro-negative body for the positive electricity united with it, and that of the electro-positive body for the negative electricity combined with it, are overcome. The result is heat and the ponderable compound. The latter retains the excess of positive or negative electricity, by which it acquires either an electro-negative or ...
Under anaerobic conditions, certain bacteria can produce electricity. This behavior can be exploited in microbial fuel cells, with a special focus on wastewater treatment schemes. A weak point is the dissatisfactory power density of the microbial cells. An unconventional solution is now presented by Singaporean and Chinese scientists: as reported in the journal Angewandte Chemie, they coated live, electroactive bacteria with a conducting polymer and obtained a high-performance anode for microbial fuel cells.. The history of microbial fuel cells goes back to the beginning of the 20th century when scientists connected bacteria cells with electrodes to generate electricity. The principle is that, if no oxygen is present, the bacterias metabolism changes to produce protons and electrons instead of carbon dioxide and water. These electrons can be used for current generation in an electrochemical cell. Such microbial fuel cells are currently heavily investigated for sustainable energy production and, ...

Bioelectrochemical systems (BES), including their most important variant, the microbial fuel cell (MFC), are rapidly developing and promising technologies for renewable energy production and wastewater treatment, among other applications (1, 2). The MFC technology aims at generating electrical current through extracellular transfer of electrons, which microorganisms liberate from organic substrates. Microorganisms oxidize organic compounds, and the electrons from the intracellular electron transport chains are transferred to an external electron acceptor (i.e., an anode poised at a suitable potential) (3). One of the challenges facing MFC performance is the efficiency of microbial electron transfer to an anode. The most commonly described transfer mechanisms are direct electron transfer via direct cell contact or protein nanowires and mediated electron transfer via secondary or primary metabolites (4-9). Attempts to improve the biological efficiency of MFCs have therefore focused on ...

Walvis Bay, Namibia - ESI-AFRICA.COM - 07 November 2011 - President Pohamba of Namibia has appealed to the countrys electricity utility NamPower to do everything in its power to explore alternative sources of energy in an effort to counter the power shortfall in Namibia. Officially launching generator number three at the new US$44 million Anixas power station, he said Namibias total power needs currently peaked at 393 megawatts (MW), and that the coming on stream of Anixas was a step in the right direction, as Namibia sought to cut down on electricity imports, mainly from South Africa. The new plant will provide additional 22.5MW to the national grid in case of emergency and during peak demand. Other main sources of electricity generation in Namibia are the Ruacana hydro electric power station (240MW), the Van Eck coal power plant in Windhoek (120MW) and the Walvis Bay Paratus diesel power station (18.5MW). Namibias current electricity demand is estimated at 550MW. The development of local ...
