Incidence and causes of tenosynovitis of the wrist extensors in long distance paddle canoeists. (1/444)

OBJECTIVES: To investigate the incidence and causes of acute tenosynovitis of the forearm of long distance canoeists. METHOD: A systematic sample of canoeists competing in four canoe marathons were interviewed. The interview included questions about the presence and severity of pain in the forearm and average training distances. Features of the paddles and canoes were determined. RESULTS: An average of 23% of the competitors in each race developed this condition. The incidence was significantly higher in the dominant than the nondominant hand but was unrelated to the type of canoe and the angle of the paddle blades. Canoeists who covered more than 100 km a week for eight weeks preceding the race had a significantly lower incidence of tenosynovitis than those who trained less. Environmental conditions during racing, including fast flowing water, high winds, and choppy waters, and the paddling techniques, especially hyperextension of the wrist during the pushing phase of the stroke, were both related to the incidence of tenosynovitis. CONCLUSION: Tenosynovitis is a common injury in long distance canoeists. The study suggests that development of tenosynovitis is not related to the equipment used, but is probably caused by difficult paddling conditions, in particular uneven surface conditions, which may cause an altered paddling style. However, a number of factors can affect canoeing style. Level of fitness and the ability to balance even a less stable canoe, thereby maintaining optimum paddling style without repeated eccentric loading of the forearm tendons to limit hyperextension of the wrist, would seem to be important.  (+info)

Hyperendemic focus of Q fever related to sheep and wind. (2/444)

Q fever is a worldwide zoonosis which is caused by Coxiella burnetii and presents as both acute or chronic cases. The disease can be transmitted from animal reservoirs to humans by the inhalation of infected aerosols. The authors investigated the epidemiology of Q fever in the Bouches-du-Rhone district of southern France. The study area was centered around the small town of Martigues near the cities of Marseille and Aix-en-Provence, where the incidence of the disease seemed higher than in neighboring areas. Epidemiologic data included sheep breeding and wind. Between 1990 and 1995, Q fever was diagnosed in 289 patients, leading to an incidence rate of 35.4 per 100,000 in the study area (range: 6-132), compared with 6.6 in the area of Marseille, and 11.4 in the area of Aix-en-Provence. There was a graphical and statistical relation between the sheep densities, the incidence of the disease, and the strong, local wind known as the Mistral, which blows from the northwest. Although Coxiella burnetii transmission is multifactorial, we may speculate that the high endemicity in the study area is related to a contamination by aerosols because the Mistral blows through the local steppe where 70,000 sheep are bred. This public health problem requires further studies in order to confirm this hypothesis, and to identify more individual and preventable risk factors.  (+info)

Shade and wind barrier effects on summertime feedlot cattle performance. (3/444)

In each of three summertime trials conducted over consecutive years, approximately 110 predominantly black and black-white-face steers were blocked by weight and randomly allotted to one of 16 pens in a 2x2 factorial arrangement of treatments. Factors consisted of cattle being fed in facilities with or without wind barriers and with or without shade. Steers were fed dry-rolled corn-based diets (1.43 Mcal/ kg, NEg). Mean starting date and days on feed were June 26 and 79, respectively. In unshaded areas, temperature and humidity averaged 21.6 degrees C and 77.9%, and the blackglobe-humidity index (BGHI) at 1500 averaged between 84.0 and 89.1. Each of four 6.1-x6.1-m structures (mean height = 3.4 m) with white steel roofs provided shade (2.65 m2/steer) for two pens. In facilities with wind barriers provided, airflow was reduced from the north and northwest by a 25-m-wide shelterbelt containing six rows of trees. For cattle fed in pens with wind barriers, shade increased (P<.05) gain from 0 to 56 d and decreased (P<.05) DMI/ADG from 0 to 28 d. Differences (P<.05) in performance were not found between shaded and unshaded cattle in any portion of the feeding period for cattle fed in the pens without wind barriers and over the entire feeding period in either type of facility. The shade response in pens with wind barriers seemed to be greater the 1st yr than in subsequent years. Differences in weather patterns among years, especially air temperature, humidity, and solar radiation, may partially explain this interaction. Also, in yr 1, cattle tended to have greater fat thickness at finish than in yr 2 and 3. Correlations between BGHI and DMI tended to be greater during the early portion of the trial (0 to 28 d) than over the entire trial. Correlations between the difference in BGHI under shade vs no shade and percentage of shade use had the greatest magnitude and were significant only in the first 28 d vs over the entire feeding period. Although no heat-related cattle deaths occurred in this study, results suggest that shade improves cattle performance in the summer when they are fed in facilities with winter wind protection available and have not become acclimated to hot conditions. Once cattle are acclimated or hot conditions subside, compensation by unshaded cattle offsets much of the initial benefits of providing shade.  (+info)

Heat balance when wearing protective clothing. (4/444)

This issue of the Annals of Occupational Hygiene is dedicated to the topic of heat stress evaluation. For this evaluation, several evaluation programs and international standards are available. In order to understand the reasoning and underlying theory behind these programs and standards, a basic knowledge of heat exchange processes between workers and their environment is needed. This paper provides an overview of the relevant heat exchange processes, and defines the relevant parameters (air and radiant temperature, humidity, wind speed, metabolic heat production and clothing insulation). Further it presents in more detail the relation between clothing material properties and properties of clothing ensembles made from those materials. The effects of clothing design, clothing fit, and clothing air permeability are discussed, and finally an overview of methods for the determination of clothing heat and vapour resistance is given.  (+info)

Clothing evaporative heat resistance--proposal for improved representation in standards and models. (5/444)

Clothing heat and vapour resistance are important inputs for standards and models dealing with thermal comfort, heat- and cold-stress. A vast database of static clothing heat resistance values is available, and this was recently expanded with correction equations to account for effects of movement and wind on the static value of heat resistance in order to obtain the dynamic heat resistance of clothing ensembles. For clothing vapour resistance, few data were available so far. Indices for vapour permeability (im) and reduction factors for vapour transfer (Fpcl) of clothing were used instead, using a relation between heat and vapour resistance to derive the clothing vapour resistance from the value for clothing heat resistance. This paper reviews the two commonly used approaches (im and Fpcl), as well as five alternative approaches to the problem. The different approaches were evaluated for their accuracy and their usability. The present paper shows that the currently used relations are not adequate when the wearer of the clothing starts moving, or is exposed to wind. Alternative approaches are shown to improve the determination of dynamic clothing vapour resistance, though some are thought to be too complex. An empirical description of the relation between the clothing permeability index (im) and the changes in clothing heat resistance due to wind and movement was selected as the most promising method for deriving clothing vapour resistance. For this method the user needs to know the static heat resistance, the static im value of the clothing and the wind- and movement-speed of the wearer. This method results in a predicted maximal decrease in clothing vapour resistance by 78%, when clothing heat resistance is reduced by 50%, which is consistent with theoretical expectations and available data.  (+info)

The effects of wind and human movement on the heat and vapour transfer properties of clothing. (6/444)

This paper integrates the research presented in the papers in this special issue of Holmer et al. and Havenith et al. [Holmer, I., Nilsson, H., Havenith, G., Parsons, K. C. (1999) Clothing convective heat exchange: proposal for improved prediction in standards and models. Annals of Occupational Hygiene, in press; Havenith, G., Holmer, I., den Hartog, E. and Parsons, K. C. (1999) Clothing evaporative heat resistance: proposal for improved representation in standards and models. Annals of Occupational Hygiene, in press] to provide a practical suggestion for improving existing clothing models so that they can account for the effects of wind and human movement. The proposed method is presented and described in the form of a BASIC computer program. Analytical methods (for example ISO 7933) for the assessment of the thermal strain caused by human exposure to hot environments require a mathematical quantification of the thermal properties of clothing. These effects are usually considered in terms of 'dry' thermal insulation and vapour resistance. This simple 'model' of clothing can account for the insulation properties of clothing which reduce heat loss (or gain) between the body and the environment and, for example, the resistance to the transfer of evaporated sweat from the skin, which is important for cooling the body in a hot environment. When a clothed person is exposed to wind, however, and when the person is active, there is a potentially significant limitation in the simple model of clothing presented above. Heat and mass transfer can take place between the microclimate (within clothing and next to the skin surface) and the external environment. The method described in this paper 'corrects' static values of clothing properties to provide dynamic values that take account of wind and human movement. It therefore allows a more complete representation of the effects of clothing on the heat strain of workers.  (+info)

The role of performance tests, manikins and test houses in defining clothing characteristics relevant to risk assessment. (7/444)

Clothing is an important determinant of human heat exchange and accordingly a critical factor for heat stress risk assessment. A large number of international standards exist concerning protective properties of clothing. However, few standards deal with ergonomic properties and requirements of clothing, making it difficult to evaluate the function of a clothing ensemble in terms of both protection and physiological strain or discomfort. The paper examines existing test methods and procedures for improvement of the situation. Much of the work are presently at research stages, but should in the near future be available for test houses and consumers.  (+info)

Effects of complex radiative and convective environments on the thermal biology of the white-crowned sparrow (Zonotrichia leucophrys gambelii). (8/444)

The energy budgets of small endotherms are profoundly affected by characteristics of the physical environment such as wind speed, air temperature and solar radiation. Among these, solar radiation represents a potentially very large heat load to small animals and may have an important influence on their thermoregulatory metabolism and heat balance. In this investigation, we examined the interactive effects of wind speed and irradiance on body temperature, thermoregulatory metabolism and heat balance in the white-crowned sparrow (Zonotrichia leucophrys gambelii). We measured changes in metabolic heat production by exposing birds to different wind speeds (0.25, 0.5, 1.0 and 2.0 m s(-1)) and irradiance combinations (<3 W m(-2) and 936+/-11 W m(-2); mean +/- s.d.) at an air temperature of 10 degrees C. Body temperature was not affected by wind speed, but was significantly higher in animals not exposed to simulated solar radiation compared with those exposed at most wind speeds. In the absence of solar radiation, metabolic heat production was strongly affected by wind speed and increased by 30 % from 122 to 159 W m(-2) as wind speed increased from 0.25 to 2.0 m s(-1). Metabolic heat production was even more strongly influenced by wind speed in the presence of simulated solar radiation and increased by 51% from 94 to 142 W m(-2) as wind speed increased from 0.25 to 2. 0 m s(-1). Solar heat gain was negatively correlated with wind speed and declined from 28 to 12 W m(-2) as wind speed increased from 0.25 to 2.0 m s(-1) and, at its maximum, equaled 11% of the radiation intercepted by the animal. The overall thermal impact of the various wind speed and irradiance combinations on the animal's heat balance was examined for each treatment. Under cold conditions, with no solar radiation present, an increase in wind speed from 0.25 to 2.0 m s(-1) was equivalent to a decrease in chamber air temperature of 12.7 degrees C. With simulated solar radiation present, a similar increase in wind speed was equivalent to a decrease in chamber air temperature of 16 degrees C. Overall, shifting environmental conditions from a wind speed of 0.25 m s(-1) and irradiance of 936 W m(-2) to a wind speed of 2.0 m s(-1) with no short-wave radiation present was equivalent to decreasing chamber air temperature by approximately 20 degrees C. The sensitivity to changes in the convective environment, combined with the complex effects of changes in irradiance levels revealed by re-analyzing data published previously, significantly complicates the task of estimating the heat balance of animals in nature.  (+info)

Background: Wind turbines are a form of renewable energy, which generate electricity from wind energy, a practice dating back over 100 years. More recently, large-scale wind energy developments have started to employ one or several industrial wind turbines, which produce the majority of wind energy in Ontario. The production of electricity from the movement of industrial wind turbine motor blades creates both mechanical and aerodynamic noise. This type of environmental noise is a growing public health concern, especially for residents living close to industrial wind turbines. A body of evidence now exists to suggest that industrial wind turbine noise can impair health and contribute to annoyance and sleep disturbance. However, in Ontario, little is known about how industrial wind turbines impact people living in their vicinity. Objectives: This investigation was a cross-sectional study involving eight Ontario communities that contain greater than ten industrial wind turbines. The objectives of ...
With a rapid growth in the renewable energy projects over the past few years, the total installed capacity of the wind power plants across the world has witnessed a manifold increase. Advancements in wind turbines designs have also led a surge in the installed capacity of wind power.. Many companies have developed wind turbines that can produce power in low wind areas with reduced costs. With a scope for development of wind farms even in offshore locations, the electricity generation from wind has been on an uptrend in many countries in recent years. Further, wind power installations occupy less space compared other modes of power generation, bringing in increased operational efficiencies. Wind farms can also be built on agricultural lands, without causing any interruption to cultivation activities.. In its Global Wind Report: Annual Market Update report, the Global Wind Energy Council (GWEC) said that cumulative global wind power capacity grew by 12.6% to reach a total of 486.8 GW in 2016. The ...
Introduction. Climate change and fossil fuel depletion have pushed many countries to seek and invest in alternative clean energy sources, such as wind energy. By converting kinetic energy from the wind into mechanical or electrical energy, wind farms in California, for example, power nearly 850,000 households each year, while producing negligible green house gases and contributing little to water pollution.[1] Nevertheless, several ecological and environmental concerns remain. High levels of infrasound and low frequency sounds generated by wind turbines pose a potentially serious threat to communities near wind farms. Wind energy companies remain largely dismissive, claiming that wind turbine noise is subaudible, undetectable by humans, and therefore presents minimal risk to human health. However, various cochlear microphonic, distortion product otoacoustic emission, and fMRI studies have demonstrated the detection of infrasound by the human inner ear and auditory cortex. Additional ...
Since the end of 1990s the growth of new energy and renewable energy production has been strong and increasing. Wind power energy has become one important source of energy almost all over the world. Europe, USA and Asia has become the leading markets in the development of wind energy. The total volume of global wind energy production has increased from 13,600 MW in 1999 to 318,137 MW in 2013. Since 2006 the wind energy industry is showing very rapid growth as well as dynamics among major industry actors. Some companies has left the industry due to heavy competion, some has used the growth as an opportunity to expand and the inceasing demand and the growth in the wind energy sector has opened opportunities for new actors to enter the industry. China has very fast become the largest country in the world in terms of installed wind energy capacity (28,7% share of total installed capacity and 45,4 % share of installed capacity in 2013). China is followed by Germany, UK and India. USA is now on the ...
Denmark and Indonesia have signed an agreement to promote and expand renewable energy infrastructure in the south-east Asian country. According to media reports, the two countries signed an agreement to set up a 60 MW wind energy project in the South Sulawesi province; the project will be the first wind energy project in the province.

In 2007, the FAST wind turbine simulation tool, developed and maintained by the U.S. Department of Energys (DOEs) National Renewable Energy Laboratory (NREL), was expanded to include capabilities that are suitable for modeling floating offshore wind turbines. In an effort to validate FAST and other offshore wind energy modeling tools, DOE funded the DeepCwind project that tested three prototype floating wind turbines at 1/50th scale in a wave basin, including a semisubmersible, a tension-leg platform, and a spar buoy. This paper describes the use of the results of the spar wave basin tests to calibrate and validate the FAST offshore floating simulation tool, and presents some initial results of simulated dynamic responses of the spar to several combinations of wind and sea states.

Since a wind turbine generates electricity from the energy in the wind, the wind leaving the turbine must have a lower energy content than the wind arriving in front of the turbine.. This follows directly from the fact that energy can neither be created nor consumed. If this sounds confusing, take a look at the definition of energy in the Reference Manual. A wind turbine will always cast a wind shade in the downwind direction. In fact, there will be a wake behind the turbine, i.e. a long trail of wind which is quite turbulent and slowed down, when compared to the wind arriving in front of the turbine. (The expression wake is obviously derived from the wake behind a ship). You can actually see the wake trailing behind a wind turbine, if you add smoke to the air passing through the turbine, as was done in the picture. (This particular turbine was designed to rotate in a counterclockwise direction which is somewhat unusual for modern wind turbines). Wind turbines in parks are usually spaced at ...
Wind Resources. (7.5 credits, Spring18/19, weeks 04-12, 50%.). In this course the concept of wind energy and the different methods that are used for wind resource assessment will be explored. Further, the factors having an influence on the wind and what they mean when assessing the wind resource at a site will be studied. Wind energy calculation methods, including how they model the wind to calculate the energy production of a wind turbine will be investigated. Different wind measurement methods and their aims of evaluating the wind conditions at a site for wind power projects are also explored.
Renewable energy wind turbines as electricity sources possess extreme environmental problems not found in their renewable energy rival-solar photovoltaic. These problems are due to rotation of 130-foot or more long, thirteen-ton turbine blades with tip speeds of 200 miles per hour. An unavoidable problem of wind turbines is killing flying creatures. The Committee For A Constructive Tomorrow (CFACT) produced a video Eagle lawsuit ruffles wind industry feathers. The video records a bird apparently being killed by a wind turbine. It appears the bird went back for a second look at the turbine and a blade struck the fatal blow. Possibly the bird thought the turbine was a bigger bird.. A companion article published March 19, 2013, by CFACT is Wind turbines kill up to 39 million birds a year by wildlife expert Jim Wiegand. Details of studies on bird fatalities caused by wind turbines are cited in this article. The source of Jim Wiegands statement wind turbines kills up to 39 million birds a year ...

While the Henry County Planning Commission recently issued a no recommendation ruling on a revised ordinance governing wind farms, members of the Sulphur Springs Town Board had an emphatically different reaction Tuesday night.. The board unanimously passed on first reading its own wind ordinance, prohibiting any wind energy system within the jurisdiction of Sulphur Springs.. The action was just part of an effort to fight wind turbine activity in Henry County. At the suggestion of concerned citizens present during the meeting, the board also directed Town Attorney Jeremy Bell to contact Syracuse attorney Steve Snyder, who has been successful in getting setbacks changed and, in one case, helping an Indiana county ban commercial wind farms entirely.. According a Feb. 18, 2015 story in the Connersville News-Examiner, a sister paper to the The Courier-Times, Snyder argued in Marshall County that setback distances needed to be increased because of population density. A similar argument was made at ...
Natural News) The Fraunhofer Institute for Wind Energy Systems (Fraunhofer IWES) is testing a new rotor blade that incorporates bend-twist coupling (BTC) technology. Wind turbines equipped with the new blade can get the most out of fluctuating winds, reported an AlphaGalileo article.. The German wind energy sector leads its European peers by a good margin. Germany operates more than 28,000 wind turbines, and their total output of 50 gigawatts accounted for a 12.3 percent share of the countrys entire electricity production in 2016.. Fraunhofer IWES is at the forefront of refining wind energy technology. The company and its partners are working on SmartBlades2, a joint project that tackles the BTC concept for wind turbine rotor blades.. A rotor blade has a large surface area that belies its slim appearance. Within that area, the strength of the wind can vary greatly and change quickly. The pressure on the blade thats pointing skyward could be very different from the pressure pushing at the ...

That didnt happen. They havent even started working on it.. The thing is, Kenya could really use this wind power. The whole continent could use wind power, but beyond South Africa, there arent a whole lot of projects in the works.. Check this out: when the Global Wind Energy Council [PDF] breaks down wind power by region, it doesnt even give Africa its own line, so minuscule is the total. Instead, Africa gets lumped in with the Middle East. And even at that, the total is a mere 1,093 megawatts (MW) out of a 238,351 MW of global wind capacity as of the end of 2011 - and more than half of that was in Egypt!. The director of the Lake Turkana Wind Power Project, Chris Staubo, told AFP recently that when (when) it comes online, the wind farm will represent 20 percent of Kenyas electricity production.. The holdup on the project is the financing, which, always complex to begin with on projects like this, is even hairier because the wind farm isnt the only thing that needs to be built.. The ...

The global wind energy market witnessed huge growth from 2009 to 2010 as total wind power capacity grew by 22.3%. The global wind energy installed capacity increased at a Compound Annual Growth Rate(CAGR) of 27.9% from 74,107 megawatt (MW) in 2006 to 198,203 MW in 2010, of which 36,100 MW went online in 2010. Although the cumulative capacity for wind power grew, there was a 10.9% fall in annual additions in 2010 as major wind markets such as the US, Germany and Spain faced economic problems following the global economic crisis. The global wind power markets are expected to recover in 2011 due to the huge order intake by major wind manufacturers, the growing Asia-Pacific (APAC) region, emerging South America and Africa regions, steady European wind markets and recovery in North America. Wind power manufacturers across the world had a high order intake in 2010 with expected delivery deadlines in 2011 and 2012. This will contribute to the annual installations in 2011-2012 ...
At the end of 2012, the European market boasted 55 offshore wind farms and the U.S. had absolutely none. The question arises: Whats the holdup?. There are a wide variety of answers to that inquiry. However, many are cleared up by Cleantechnica.coms new report, titled Where Do I Put My Offshore Wind Farm?, a two-page synopsis on the present status of wind farms in the U.S. as a source of alternative energy.. This short analysis links readers to a vast wealth of information on this emerging industry and touches on such diverse issues as initial funding, siting, wind speeds, water depths, federal vs. state waters, transmission lines, hurricane risk, and public opinion.. Ironically, the political factor is not highlighted in this assessment. With new drive for America to invest in energy independence, it seems that future development of offshore wind farms has the solid political support of many governors - especially those on the East Coast. ...

While large wind mills that are installed in clusters at wind farms produce energy on a massive scale, small wind turbines produce energy at lower levels. Unlike large wind turbines, this technology helps produce wind energy in the low to medium paced wind conditions and is developed to promote in-house energy production among households, farms and small businesses. Wind energy has long been exploited as a significant alternative source of power generation in the country through large wind mills. But, they require high speed winds to produce electricity. In this scenario, small wind turbines technology has surfaced as a remarkable development in the wind energy sector as it generates power in low and medium paced wind. This technology, therefore, is ideal for country like India where majority of regions have low to medium paced winds. Small Wind Turbines (SWT), though in its infancy stage, is set to evolve and grow large as it taps full potential of wind in generating sustainable, economical and ...

1. The advantages offered by utilizing wind energy to develop aquaculture production not only include promoting fish or shrimp growth, lowering of incidence of disease, using less feed and increasing fish yield, but also include saving conventional energy (fuel or electricity) consumption. At present, there are more than 60, 000 sets of oxygen-enhancing equipment in China. Most of the equipment is being driven by fuel or electricity. However, the price of fuel and electricity are high. On the other hand, in some sparsely populated regions as well as islands and remote border regions, the national electricity grid has not yet been installed or electricity supply is serious inadequate. Since wind energy source is considerably abundant in these regions, the prospects of utilizing wind energy to develop fishery is bright in these regions. 2. As mentioned above, it is important for fish, especially for prawn, to replace old water in fishponds with fresh water. Regulating water quality is a key link ...

Dutch Wind Energy Research Preface Wind energy research and education in the Netherlands We are very pleased to present you an overview of the wind energy research and education in the Netherlands. It
Most offshore wind turbines (OWTs) are designed according to the international standard IEC 61400-3 which requires consideration of several design load cases under 50-year extreme storm conditions during which the wind turbine is not operational (i.e. the rotor is parked and blades are feathered). Each of these load cases depends on combinations of at least three jointly distributed metocean parameters, the mean wind speed, the significant wave height, and the peak spectral period. In practice, these variables are commonly estimated for the 50-year extreme storm using a simple but coarse method, wherein 50-year values of wind speed and wave height are calculated independently and combined with a range of peak spectral period conditioned on the 50-year wave height. The IEC Standard does not provide detailed guidance on how to calculate the appropriate range of peak spectral period. Given the varying correlation of these parameters from site-to-site, this approach is clearly an approximation which ...
OCEAN CITY - Independent stakeholders in one of two offshore wind projects appear to have little concern with the significantly larger turbines selected, according to briefs filed with the Maryland Public Service Commission following a hearing last month.. In June, the Maryland Public Service Commission (PSC) held an evidentiary hearing on the proposed change in wind turbine size for Orsteds Skipjack project off the coast of Ocean City. The evidentiary hearing was called when Skipjack announced its intention to switch from the previously proposed eight-megawatt turbines to the much larger 12-megawatt turbine, now believed to be the largest commercial wind turbine available.. When Skipjack moved to the 12-megawatt turbine, the Town of Ocean City urged the PSC to hold an evidentiary hearing on the proposed turbine change. After a well-attended public hearing in Ocean City in January, the PSC agreed to hold the evidentiary hearing and it took place virtually in early June.. Last week, several ...
We now have another study that confirms that there are no health impacts associated with living near wind farms.. The study, conducted by Health Canada at a cost of $2.1 million, agrees with the findings of the study by Ontarios Medical Officer of Health, which found no causal link between wind turbine noise and adverse health effects. A study by the American Psychological Association found the same. So have a myriad of other studies done over the years in multiple jurisdictions.. Health Canadas study found that there was no relationship between wind turbines and reports of trouble sleeping, incidence of self-reported illness, stress, or quality of life.. They did, however, find that some people are annoyed by wind farms. In the language of epidemiology, the study found a correlation, but not a causal relationship, between increasing levels of wind turbine noise and annoyance.. The authors note that the levels of annoyance may be linked to other issues, such as health, overall economic ...

China is the worlds leader in installed wind power capacity. After years of development in the countrys north, northeastern and northwestern areas, wind power is spreading across China. Greenpeaces annual industry analysis China Wind Power Outlook predicts that Chinas installed wind power capacity will be between 200 and 300 GW by 2020 and over 400 GW by 2030. And that by 2030, wind power will make up about 8.4% of Chinas total electricity generation, and 15% of Chinas installed capacity. It estimates that in 2011 Chinas wind energy sector generated 71.5 billion kilowatt hours, equivalent to the annual electricity demand of over 47 million households.

This research work, named as CryoVent, was focused on determining the feasibility of using wind energy, to produce liquefied gases (cryogens) continuously in a safe approach that can be used for the cooling and ventilation of underground mines. The experimental work performed suggested that the continuous production of liquefied gases with variable input work is practical. The average specific power consumption for liquefaction of nitrogen in this work was 7.86 kWh/kg using the refrigeration produced by helium. This is ~20 times higher than that consumed by industrial scale gas liquefaction systems, but is practical for a small scale system. This specific power consumption could probably be lowered if the working fluid itself is liquefied. Analysis on wind speed variability and wind speed data synthesis were also performed which suggested presence of multi-fractal nature in wind speed data that represent the temporal variation. A new method developed to generate high sampling frequency wind ...
Hydrogen production with offshore wind and sea water electrolysis, 978-3-659-82387-9, 9783659823879, 3659823872, Heating,- energy- and power station technology, Jules Verne, The Mysterious Island, 1874: Yes, my friends, I believe that water will one day be employed as fuel, that hydrogen and oxygen which constitute it, used singly or together, will furnish an inexhaustible source of heat and light, of an intensity of which coal is not capable. -- -- -- -- What if there was a way to capitalize Norways offshore wind potential while becoming one of the largest producers of the fuel of the future - hydrogen? This study elaborates the idea of offshore hydrogen production platforms that could be used to produce hydrogen from offshore wind. Norway is one of the largest producers of fossil fuels and a clean energy pioneer. As the Norwegian energy demand can be covered with hydropower, there is no need to capitalize offshore wind potentials - unless there is another way: by using offshore wind potentials to
If we achieve our vision of 1.4 TW of offshore wind by 2050, this would mean that ocean-based renewable energy could supply 10% of the worlds electricity by 2050. Offshore wind has the greatest potential of the ocean-based renewable energy technologies. Our vision is for the 1.4TW be delivered by to be achieved by offshore wind alone. This is beyond the level of recent forecasts.. The World Bank estimates that this is still less than 10% of the technical potential for offshore wind in 48 emerging markets. Other ocean renewable technologies could provide father carbon savings and economic benefits to countries if these technologies are brought to commercialisation.. Offshore wind can fill the gap left by retiring fossil fuel capacity and meet demand from the electrification of transport and heating. It can reduce reliance on imported energy, which can be subject to significant price fluctuations.. For countries that have grids built to transmit power from traditional fossil fuel generation to ...
Wind farms produce electricity without causing air pollution and environmental degradation. Unfortunately, wind turbines are a source of infrasound, which may cause a number of physiological effects, such as an increase in cortisol and catecholamine secretion. The impact of infrasound noise, emitted by wind turbines, on the health of geese and other farm animals has not previously been evaluated. Therefore, the aim of this study was to determine the effect of noise, generated by wind turbines, on the stress parameters (cortisol) and the weight gain of geese kept in surrounding areas. The study consisted of 40 individuals of 5- week- old domestic geese Anser anser f domestica, divided into 2 equal groups. The first experimental gaggle (I) remained within 50 m from turbine and the second one (II) within 500 m. During the 12 weeks of the study, noise measurements were also taken. Weight gain and the concentration of cortisol in blood were assessed and significant differences in both cases were ...
Good news for clean energy! On Monday, Microsoft has announced that its biggest wind energy purchase. The tech giant has signed a new wind farm contract to purchase 237 MW of wind energy capable of powering their Wyoming Data Center.
abstractNote = {A combined power station is described, which enables one to convert solar energy and wind energy into other forms of energy. The plant consists of a water-filled boiler, in which solar energy heats the water by concentration, solar cells, and finally wind rotors, which transform wind energy into electrical energy. The transformed energy is partly available as steam heat, partly as mechanical or electrical energy. The plant can be used for supplying heating systems or electrolysis equipment. Finally, by incorporating suitable motors, a mobile version of the system can be produced ...
The wind chill index is considered dangerous when temperature and wind speed combine to make it feel like 0 degrees or lower. For example, using the chart above, a temperature of 15 degrees with a wind speed of 25 mph net a wind chill index of -4 degrees. Other than the chart, try using our meteorological calculator by clicking here.. When wind chill index values reach 0 degrees for several hours over a fairly large area (with a wind speed of at least 10 mph), the National Weather Service will usually issue a Wind Chill Advisory.. When wind chill index values reach -15 degrees for one hour over a fairly large area (with a wind speed of at least 10 mph), a Wind Chill Warning may be posted.. ...
There is a term used a lot in the Nebraska Capitol. Nebraska Nice. Wind energy is not Nebraska Nice. Wind energy is a scam that hurts people and animals, wastes billions in tax dollars, and isnt green energy by any definition of the term. Industrial wind energy projects also make terrible neighbors and will utterly destroy the most environmentally sensitive part of our State.. Last week the Natural Resources Committee held an interim study hearing on Public Power. A portion of that hearing was devoted to renewable energy (wind energy). The chairman of the committee, Sen. Dan Hughes, supports wind energy, but to his credit, he ran an excellent hearing and was exceptionally fair to all who participated. Sen. John McCollister of Omaha is on the committee. He posted an Op Ed in the Omaha paper this week about how wonderful wind energy is. This probably explains why he left the hearing early and didnt hear the many citizens who testified against it. I hope he shows more courtesy to his ...
Collision with turbines and disturbance leading to loss of or reduced habitat quality are the two main impacts from wind energy development on birds. In addition, wind farms can act as barriers to birds. The conflict between birds and wind farms are highly site-, season- and species-specific. Among the most vulnerable group of birds are the raptorial species. Large soaring birds have proven to be particularly vulnerable to collision with turbines. In this thesis I aimed to test if a 68-turbine wind farm on the island of Smøla, mid-Norway, was in conflict with a population of white-tailed eagles breeding at high density. The white-tailed eagle is a species with slow reproduction, long life span and high annual survival rates. These demographic characteristics make them particularly vulnerable to increased mortality. I found that the white-tailed eagle population was affected both by disturbance and collision mortality. Eagles did not significantly change their flight behavior when inside the ...
by Lee Greenburg, Ottawa Citizen. TORONTO - A government lawyer fighting off a major challenge to wind energy in Ontario says the foremost health impact complained about by detractors is not a medical condition at all, but a fact of life.. Frederika Rotter cast aspersions on the term annoyance, which opponents describe as a critical health condition caused by giant wind turbines, which emit noise that, they say, causes a number of other physiological effects, including sleep disturbance, headache, irritability, problems with concentration and depression.. Annoyance doesnt equal serious harm to human health, Rotter told an Environmental Review Tribunal panel Thursday. You could be annoyed by your neighbours screaming. Everyone suffers from annoyance.. Eric Gillespie, a lawyer for an anti-wind group hoping to keep industrial wind farms out of the province, argued Thursday that the government didnt adequately consider the adverse effects of wind turbines on human health.. The hearing ...
To understand better how complex interactions between environmental variables affect the energy balance of small diurnal animals, we studied the effects of the absence and presence of 950 W m(−)(2) simulated solar radiation combined with wind speeds ranging from 0. 25 to 1.00 m s(−)(1) on the metabolic rate and body temperature of the round-tailed ground squirrel Spermophilus tereticaudus. As wind speed increased from 0.25 to 1.00 m s(−)(1), metabolic heat production increased by 0.94 W in the absence of solar radiation and by 0.98 W in the presence of 950 W m(−)(2) simulated solar radiation. Exposure to simulated solar radiation reduced metabolic heat production by 0.68 W at a wind speed of 0.25 m s(−)(1), by 0.64 W at 0.50 m s(−)(1) and by 0.64 W at 1.00 m s(−)(1). Body temperature was significantly affected by environmental conditions, ranging from 32. 5 degrees C at a wind speed of 1.0 m s(−)(1) and no irradiance to 35. 6 degrees C at a wind speed of 0.50 m s(−)(1) with 950 ...
Arniefoul, Glamis, Scotland. I live at Arniefoul which is 5km East of the Ark Hill wind turbines and 1.6km West of the proposed Govals wind turbines (6 x 87m turbines). The prevailing wind is from the West.. Ark Hill was commissioned on 5 March 2013 and at that time I started to have continuous headaches with some light-headedness and tinnitus. Further to this, I also started to suffer frequent sleep disturbance. When I awoke I could often hear the whooshing of the turbine blades. Assuming it was the audible sound that was disturbing me, I moved my bed further away from the window and slept with the window closed. This made no difference to my sleep deprivation - usually being woken at around 3am until 5am. With the window closed I rarely hear the turbine noise, but I can sometimes feel their rhythm and therefore deduce that it is an inaudible noise (Low Frequency Noise and Infrasound) that is causing the lack of sleep.. In June 2013 I had two dizzy spells when out walking on the hills ...
File photo: Siemens. By William Mathis and Laura Millan Lombrana (Bloomberg) - Siemens Gamesa Renewable Energy SA has one eye on the future where its wind turbines could play a key role in creating hydrogen.. The company, which earlier this year launched the worlds biggest wind turbine, plans to start a pilot project in Denmark to test how its machines could power production of the fuel seen as key to eliminating carbon emissions from transportation and heavy industries. The European Union has big plans for the clean-burning gas and the bloc placed it at the center of its Green Deal earlier this year.. The pilot project is under construction near Siemens Gamesas Danish headquarters in Brande, western Denmark, Chief Executive Officer Andreas Nauen said in an interview on Thursday. It will include a 3-megawatt wind turbine that will power a 400-kilowatt electrolyzer, a machine that separates the hydrogen atoms in water from oxygen atoms.. We will be for the first time combining the two ...
Wind energy would power the equivalent of about 1 in 4 New Hampshire households if companies proceed with plans to build five proposed wind farms over the next several years to join three others already in service.
TY - JOUR. T1 - Potential of wind-powered renewable energy membrane systems for Ghana. AU - Park, G. L.. AU - Schäfer, A. I.. AU - Richards, B. S.. PY - 2009/11/15. Y1 - 2009/11/15. N2 - Areas of the world that lack fresh water often have an ample supply of wind or solar energy, making renewable energy an attractive option as a power source for desalination systems. Particularly, wind energy is attractive because of its relatively low cost, high efficiency, and recent technological advancements in this area of research. To open system applicability to a broader range of geographical areas, the feasibility of substituting solar panels with a wind turbine on an existing membrane desalination systemthat has undergone testing in the Australian outback is examined. The use of wind turbines will provide greater scope for the systems implementation in various parts of the world according to the local wind or solar resources.Acomparison of several small wind turbines coupled with wind speed data from ...
From a survey of the published literature, I could only find the names of eleven authors who had written more than one published piece claiming that wind turbines are dangerous - published by someone other than themselves or each other (and I am including blogging as self-publication). In terms of impact factor (a common way to gauge the influence or reliability of a published source), this puts Wind Turbine Syndrome below just about any crazy idea you can come up with, less popular even than the claim that world leaders are reptilian aliens wearing electronic disguises.. Considering this, its received an outrageously disproportionate amount of attention from the press. Why? Probably the same reason the press promotes any wild or sensational idea. It garners eyeball share and sells ads.. Now, obviously, the lack of support among researchers does not prove that Wind Turbine Syndrome doesnt exist; the bandwagon fallacy explicitly states that popular belief does not constitute proof. Its ...
National Institute on Deafness and other Communication Disorders. A wind turbine is a rotary device with a gigantic propeller as big as a football field that turns in the wind to generate electricity. Although wind turbines are more often found in Europe than in the United States, theyre rapidly becoming more popular here as a green energy source. Most people consider that a good thing, except the rotors of wind turbines also generate noise, particularly in the infrasound range, that some people claim makes them feel sick.. Since frequencies that low cant be heard, many scientists who study hearing have assumed they cant have any effect on the function of the ear. But a little known phenomenon related to the infrasound generated by wind turbines is making some scientists challenge the common wisdom that what we cant hear wont hurt us.. Infrasound is a subset of sound broadly defined as any sound lower than 20 Hertz (Hz), which is the lowest pitch that most people can hear. Its all around ...

Using the Heliospheric imager onboard STEREO, scientists studied the movements of hundreds of dense clumps of glowing, ionized gas within the ribbon of Comet Enckes tail, which passed by STEREO in 2007. Fluctuations in the solar wind are mirrored in changes in the tail. By tracking these clumps, scientists were able to reconstruct the motion of the solar wind, catching an unprecedented look at its turbulence.. Turbulence in the solar wind could provide one of the answers to the mystery of the solar wind heating. Based on analysis of the comet tail motions, the researchers calculated that large-scale turbulence provides sufficient kinetic energy to drive the high-temperatures observed in the solar wind.. Turbulence may also explain solar wind variability. Turbulent motion mixes up the solar wind, leading to the rapid variation that we see at Earth, said DeForest.. In situ measurements are limited because they cannot follow the turbulence along its path, said William Matthaeus, a professor ...
11 April 2019. There was shock, surprise, and humor in the media when Trump not only denounced wind mills for intermittency, lack of predictable value, property losses, and bird kills but also topped his discussion with. They say the noise causes cancer. You tell me that one, okay?. Is President Trump correct in his five critical points? Even the last one? Or is it possible, as Trevor Noah suggested, turbines might be the only things that dont cause cancer.. 1. Intermittency. Electricity must be consumed the moment it is produced. Storage to allow deviations is prohibitively expensive in all but the rarest of settings. And it has always been this way.. Trump said, Honey Id like to watch TV tonight: are the turbines working? And then his quotation from the Washington Republican fundraiser:. Is the wind blowing? Id love to watch a show tonight, darling. The wind hasnt blown for three days. I cant watch television, darling. Darling, please, tell the wind to blow.. Using humor, and ...
As part of the Columbia Power Plant Impact Study meteorological data were collected at a network of monitoring sites from 1972 through 1977. The data were the basis for a series of studies whose purpose was to elucidate the transport of airborne pollutants and to assess the climatic impact of the power plant. In a pilot diffusion climatology survey, local wind structure was interpreted in the context of synoptic weather patterns. A significant new low wind statistic was introduced. A case study traced the movement of an elevated level of ozone from the Southern Plains across the Midwest to the East Coast. It showed that long distance transport is necessary for elevated O3 levels to occur in most parts of the U.S. The horizontal variation of the wind field is an important factor in the transport of atmospheric pollutants from 10 to 100 km. The wind field was shown to be organized as a function of wind direction and wind speed around the Baraboo Hills. Two models for estimating concentrations of ...
Adaptive Rectifier Driven by Power Intake Predictors for Wind Energy Harvesting Sensor Networks - Porcarelli, D. ; Spenza, Dora ; Brunelli, D. ; Cammarano, Alessandro ; Petrioli, Chiara ; Benini, L. - This paper presents a power management technique for improving the efficiency of harvesting energy from air-flows in wireless sensor networks (WSNs) applications. The proposed architecture consists of a two-stage energy conversion circuit: an AC-DC converter followed by a DC-DC buck-boost regulator with Maximum Power Point Tracking (MPPT) capability. The key feature of the proposed solution is the adaptive hybrid voltage rectifier, which exploits both passive and active topologies combined with power prediction algorithms. The adaptive converter significantly outperforms other solutions, increasing the efficiency between 10% and 30% with respect to the only-passive and the only-active topologies. To assess the performance of this approach in a real-life scenario, air-flow data have been collected by
Day 5. The last day, it was off to the Wild Horse Wind Farm. Heres some of what he learned: the tower of a wind turbine there is taller than the Eiffel Tower, the distance from one end of the turbine blade to the other is longer than a 747. He could also tell me exactly how many mega watts a wind farm created and how many homes it could power. His takeaway? Id like to own a wind farm because I could make money. They say you should always judge the value of an activity by how your kid feels about it when they are finished. I asked my son if it was fun and he said yes. I asked him if hed do it again and he said yes. Thats a pretty good recommendation from someone who most of time wants to sit in his room and play Nintendo.. Heres the link in case YOU have a 12 year old like mine. I think they actually serve a range of kids. It wasnt the cheapest camp week weve ever put him in, but I do think it was a worthwhile experience.. And no one ran anyones skivvies up the flagpole.. ...
TY - JOUR. T1 - Examination of climatological wind patterns and simulated pollen dispersion in a complex island environment. AU - Viner, Brian J.. AU - Arritt, Raymond W.. AU - Westgate, Mark E.. PY - 2017/8/1. Y1 - 2017/8/1. N2 - Complex terrain creates small-scale circulations which affect pollen dispersion but may be missed by meteorological observing networks and coarse-grid meteorological models. On volcanic islands, these circulations result from differing rates of surface heating between land and sea as well as rugged terrain. We simulated the transport of bentgrass, ryegrass, and maize pollen from 30 sources within the agricultural regions of the Hawaiian island Kauai during climatological conditions spanning season conditions and the La Niña, El Niño, and neutral phases of the El Niño-Southern Oscillation. Both pollen size and source location had major effects on predicted dispersion over and near the island. Three patterns of pollen dispersion were identified in response to ...

Hunting kestrels were observed to hang, almost without wing-flapping, in fixed positions over a sea dike. The height and position with respect to the dike profile, the wind direction and velocity and the percentage of hunting time without wing beating were recorded in 429 cases.. The vertical wind angle, θ, the wind speed and its horizontal direction were measured at 13 heights up to 8.8m above the windward slope, the top and the leeward slope of the dike under various wind conditions in 225 cases. These wind profile measurements were used to estimate 6 and wind speed near the hanging birds.. Kestrels hanging more than 90% of the hunting time preferred a position 6.5±1.5m (S.D.) over the windward slope with sea winds blowing at 8.7±1.5ms−1 (S.D.) perpendicular (±30°) to the longitudinal dike axis. For these birds angle θ was approximately 6-7°.. These angles are larger than expected from aerodynamic models and windtunnel measurements. The minimum gliding angle for a kestrel under steady ...

TY - JOUR. T1 - Piecewise linear aeroelastic rotor-tower models for efficient wind turbine simulations. AU - Macquart, Terence. AU - Scott, Samuel J. AU - Weaver, Paul M. AU - Pirrera, Alberto. PY - 2020/9/22. Y1 - 2020/9/22. N2 - The development of software and methodologies able to efficiently and accurately predict the aeroelastic performance of wind turbines at low computational cost - enabling the rapid turnaround of novel concepts - is key to further reducing the levelised cost of energy. However, even the conventional low fidelity methods used for preliminary blade and rotor design are computationally expensive. The authors propose to improve the computational efficiency of dynamic aeroelastic time domain simulations by substituting conventional models with a piecewise linear aeroelastic rotor-tower model. This novel piecewise linear model is described and compared against standard modelling tools in this paper. Results suggest that piecewise linear rotor-tower models can be used to ...
The size of wind turbines are limited by the width of the roads theyre transported on, but now GE is paving the way for wind turbines that are truly massive.
There is a lot of energy that we can harness if we only seek to research and develop the technologies needed to do so. We can get away from the fossil fuels and the old electrical grids by turning to alternatives to these energy sources.. One of these alternative energy resources is wind power. Wind turbines continue to be developed that are progressively more energy efficient and less costly. Wind farms have been springing up in many nations, and they have even become more strategically placed over time so that they are not jeopardizing birds as former wind turbines did.. Another alternative energy resource is the one that is most well known: solar energy. This involves the manufacturing of solar cells which gather and focus the energy given off directly by the sun, and translate it into electricity or, in some cases, hot water. As with wind energy, solar energy creates absolutely zero pollution.. Ocean wave energy is seen by governments and investors as having enormous energy generating ...

The activation of the phenylpropanoid pathway in plants by environmental stimuli is one of the most universal biochemical stress responses known. Induction of enzymes such as phenylalanine ammonia-lyase and peroxidase and the accumulation of such phenolics as lignin can occur in response to insect and pathogen attack, exposure to oxidizing pollutants, and mechanical stimulation, and are thought to function in the resistance of plants to damage by these stresses. I investigated whether induction of components of this generalized stress response by wind-induced mechanical stimulation could influence the resistance to pests of common bean. In greenhouse studies, exposure of 7- to 10-day-old bean seedlings to daily periods of fan-produced wind led to increased activities of peroxidase and cinnamyl alcohol-dehydrogenase and enhanced the accumulation of lignin in primary leaves of these plants. Egg production and population growth of two-spotted spider mites were reduced when offered leaves of mechanically
A wind farm in the state of Victoria in Australia. (Photo: Jorge Láscar/CC BY 2.0). Wind turbine syndrome probably isnt real.. But thats not going to stop Australia from spending $2.5 million to, they say, find out for sure. People who claim to suffer from the syndrome experience spells of dizziness, have trouble sleeping, and get painful headaches. But most scientists and doctors-as well as the Centers for Disease Control and Prevention-do not recognize the disease, calling it a psychosomatic disorder at best. But Australia, it seems, isnt convinced, announcing Tuesday that they will award more money to to study the disease over the next five years. The new investigation into wind turbine syndrome follows an Australian study from last year that concluded there was no direct evidence tying wind farms with any changes in health.. Disease or not, it hasnt stopped Australias rapid move into wind power, which now accounts for around four percent of all electricity in the country. Situated in ...

Currently most of the aerodynamic shape design of wind turbine blades is still based on the blade element-momentum (BEM) theory with 2D airfoil data from wind tunnel experiments or CFD predictions. 3D stall delay phenomenon happens, resulting in great difference of airfoil loading from the 2D data. A general model for 3D stall delay, related with all the possible parameters, are proposed by use of the Πtheorem Based on NREL Phase VI experimental data, comparisons and analysis of two 3D stall delay models, Chaviaropoulos & Hansen and Du & Selig models are made. The model parameters in Chaviaropoulos & Hansen models are systematically tested. A correction for improving this model is put forward and compared with the experimental data. ...

Abstract. Climate change is exerting significant impacts on global agricultural production. Climatic variations adversely affect crop production and, thus tend to impose a key constraint of agricultural production, primarily on how to cont inuously enhance the winter wheat yields worldwide. The high uncertainties in predicting the effects of climate change on wheat production are most likely due to rare understanding on the responses of wheat production to extreme climatic factors, e.g. high temperatures, low humidity as well as high wind speed. Dry-hot wind hazard represents one of the main natural disasters for Chinese winter wheat production, especially for the Huang-huai-hai plain. However, high uncertainties of the effects of dry-hot wind hazard on winter wheat production still exist, mainly due to the gaps of long-term observations. Therefore, we selected Shangqiu as the case study area to determine the occurrence regularity of dry-hot wind hazard on winter wheat production in ...
