    The National Renewable Energy Laboratory (NREL) has been testing amorphous silicon (a-Si) Photovoltaic (PV) modules for more than a decade. NREL has been conducting controlled light-soak testing of multijunction a-Si modules to characterize their performance for stability evaluation as well as to benchmark the technology status. Some of the test modules, after controlled light-soak testing, have been installed outdoors. The authors have observed that under outdoor exposure, the modules further degrade in performance, possibly due to lower outdoor temperatures and varying spectra. The paper presents data on the light-induced degradation for the third controlled light-soak test on multijunction a-Si modules as well as outdoor performance data on single- and multijunction modules under prevailing conditions.

  18. A validated model to predict microalgae growth in outdoor pond cultures subjected to fluctuating light intensities and water temperatures

    2015-12-11

    Here, a microalgae biomass growth model was developed for screening novel strains for their potential to exhibit high biomass productivities under nutrient-replete conditions in outdoor ponds subjected to fluctuating light intensities and water temperatures. Growth is modeled by first estimating the light attenuation by biomass according to a scatter-corrected Beer-Lambert Law, and then calculating the specific growth rate in discretized culture volume slices that receive declining light intensities due to attenuation. The model requires the following experimentally determined strain-specific input parameters: specific growth rate as a function of light intensity and temperature, biomass loss rate in the dark as a function of temperature and average light intensity during the preceding light period, and the scatter-corrected biomass light absorption coefficient. The model was successful in predicting the growth performance and biomass productivity of three different microalgae species (Chlorella sorokiniana, Nannochloropsis salina, and Picochlorum sp.) in raceway pond cultures (batch and semi-continuous) subjected to diurnal sunlight intensity and water temperature variations. Model predictions were moderately sensitive to minor deviations in input parameters. To increase the predictive power of this and other microalgae biomass growth models, a better understanding of the effects of mixing-induced rapid light dark cycles on photo-inhibition and short-term biomass losses due to dark respiration in the aphotic zone of the pond is needed.

  1. Lights out on federal power: A plan to privatize the PMAs

    SciTech Connect (OSTI)

    Block, M.K.; Shadegg, J.

    1997-11-01

    Privatizing the power marketing administrations makes sense. Unless these federal administrations are sold, taxpayers will continue to subsidize power to the rich, and the PMAs will distort and hinder competition in the electric energy market. Employ this plan today and it will be possible to achieve benefits for all stakeholders. If there were a book entitled Privatization in The United States, it would be very thin indeed. It would be so partly because America did not participate as extensively as most countries in this century`s destructive experiment where governments produced goods that would be more efficiently produced by the private sector. Unfortunately, the book also would be thin because Americans have been less aggressive and imaginative than countries from Great Britain to Bolivia in withdrawing their national government from activities better suited to the private sector. One obvious target for immediate privatization is the federal electric power resources. This article proposes a politically viable plan to expand privatization in America by selling three of the federal government`s power marketing administrations. The PMAs, as they are known to the cognoscenti, market power generated by federally owned dams. Currently, the federal government is the nation`s largest producer and transmitter of electricity. While the government`s involvement in the electricity industry was once justified, these reasons no longer exist.

    SciTech Connect (OSTI)

    Copulos, M.R.

    1983-01-01

    The government has abandoned an increasing number of research projects, of which the Clinch River Breeder Reactor is the most recent, despite the large sums of public and private dollars already invested. Privatization may be the best way to solve energy problems, save taxpayers a minimum of $2 billion in return, and depoliticize energy research. The Electric Power Research Institute can serve as a model for a system in which industry users would be assessed for a research trust fund that would provide stable funding and allow long-range planning. The EPRI model could also help to overcome information sharing and antitrust constraints. (DCK)

    The Philipines power market, considered one of the more mature markets in Asia, continues to expand with economic growth. Independent power producers will find opportunities in the next few years as new additions are required. Currently, the government is encouraging private investment and is awaiting feedback from financiers as it considers eliminating its government guarantee. In a recent interview, the Honorable Mariano S. Salazar, secretary of energy, with the Philippines` Department of Energy, discussed the regulatory structure, encouragement of private power and his country`s capital needs.

  12. Determining Outdoor CPV Cell Temperature: Preprint

    2011-07-01

    An accurate method is needed for determining cell temperature when measuring CPV modules outdoors. It has been suggested that cell temperature can be calculated though a procedure that shutters sunlight to the cells while measuring the transients in open-circuit voltage (Voc) and heat sink temperature. This paper documents application of this shutter procedure to multiple CPV modules at NREL. The challenges and limitations are presented along with an alternate approach to measuring CPV cell operating temperature.

    SciTech Connect (OSTI)

    Holman, R.; Kennedy, R.

    1997-12-31

    Radiation cured coatings are used almost exclusively on products which have little or no exposure to moisture or the weather; inks, furniture varnishes, floor varnishes and coatings for electronic components. However there is considerable interest in being able to use this technology in exterior environments as a substitute for solvent-borne coatings. A 3-year study examining the possible reasons for the poor durability of radiation curable coatings showed that the resistance of the monomers and oligomers to hydrogen abstraction was crucially important, and the water permeability of the cured coating influenced the long-term adhesion performance. The project concluded that with the appropriate combination of curing technology and monomer/oligomer selection, the prospects of UV curable coatings for outdoor exposure are very encouraging.

    Bolivia is boldly embracing a free market philosophy that extends to liberalization of the country`s petroleum sector. Although petroleum industry privatization is being considered by several South American countries, only Argentina has so far completely opened its oil sector and fully privatized its state oil company. The Bolivian government`s own version of privatization, capitalization, is a groundbreaking attempt to attract massive investment from the private sector without leaving the government open to accusations of stripping the country`s assets for short term electoral gain. The paper discusses the government`s strategy to sell the state owned company either as a single unit or to split it into upstream and downstream units. Questions still to be resolved, international interest in the move, bolivian potential, and the gas supply infrastructure are also discussed.

    The electrical system for the Phase 1 privatization facilities will support the TWRS mission by providing the electrical power to the Phase 1 privatized facilities. This system will receive power from the Department of Energy-Richland Operations (RL) A4-8 230 kV transmission system powered from Bonneville Power Administration (BPA) Ashe and Midway 230 kV Substations. The existing RL 230 kV transmission line will be modified and looped 1021 into the new 230 kV substation bus. The new substation will be located in the vicinity of the privatized facilities, approximately 3.2 km (2 mi) south of the existing RL A4-8 230 kV transmission line. The substation will be capable of providing up to 40 MW of electrical power to support the Phase 1 privatization facilities and has space for accommodating future expansions. The substation will require at least two 230-13.8 kV transformers, 13.8 kV split bus switchgear, switchgear building, grounding transformers, instrument transformers, control and monitoring equipment, associated protection and isolation devices, lightning protection, yard lighting, cable and raceways, and infrastructure needed to provide desired availability and reliability. The power from the 13.8 kV switchgear located in the switchgear building will be delivered at the privatization facilities site boundaries. The 13.8 kV distribution system inside the privatization facilities site boundaries is the responsibility of the privatization contract.

    SciTech Connect (OSTI)

    Tiax Llc

    2006-02-28

    Energy use of rooftop and other unitary air-conditioners in commercial applications accounts for about 1 quad (10{sup 15} Btu) of primary energy use annually in the U.S. [Reference 7]. The realization that this cooling equipment accounts for the majority of commercial building cooled floorspace and the majority also of commercial building energy use has spurred development of improved-efficiency equipment as well as development of stricter standards addressing efficiency levels. Another key market driver affecting design of rooftop air-conditioning equipment has been concern regarding comfort and the control of humidity. Trends for increases in outdoor air ventilation rates in certain applications, and the increasing concern about indoor air quality problems associated with humidity levels and moisture in buildings points to a need for improved dehumidification capability in air-conditioning equipment of all types. In many cases addressing this issue exacerbates energy efficiency, and vice versa. The integrated dedicated outdoor air system configuration developed in this project addresses both energy and comfort/humidity issues.

  12. Bounds on the sample complexity for private learning and private data release

    SciTech Connect (OSTI)

    Kasiviswanathan, Shiva; Beime, Amos; Nissim, Kobbi

    2009-01-01

    Learning is a task that generalizes many of the analyses that are applied to collections of data, and in particular, collections of sensitive individual information. Hence, it is natural to ask what can be learned while preserving individual privacy. [Kasiviswanathan, Lee, Nissim, Raskhodnikova, and Smith; FOCS 2008] initiated such a discussion. They formalized the notion of private learning, as a combination of PAC learning and differential privacy, and investigated what concept classes can be learned privately. Somewhat surprisingly, they showed that, ignoring time complexity, every PAC learning task could be performed privately with polynomially many samples, and in many natural cases this could even be done in polynomial time. While these results seem to equate non-private and private learning, there is still a significant gap: the sample complexity of (non-private) PAC learning is crisply characterized in terms of the VC-dimension of the concept class, whereas this relationship is lost in the constructions of private learners, which exhibit, generally, a higher sample complexity. Looking into this gap, we examine several private learning tasks and give tight bounds on their sample complexity. In particular, we show strong separations between sample complexities of proper and improper private learners (such separation does not exist for non-private learners), and between sample complexities of efficient and inefficient proper private learners. Our results show that VC-dimension is not the right measure for characterizing the sample complexity of proper private learning. We also examine the task of private data release (as initiated by [Blum, Ligett, and Roth; STOC 2008]), and give new lower bounds on the sample complexity. Our results show that the logarithmic dependence on size of the instance space is essential for private data release.

    We assess the measurement of hyperspectral reflectance for the outdoor monitoring of green algae and cyanobacteria cultures with a multi-channel, fiber-coupled spectroradiometer. Reflectance data acquired over a four-week period are interpreted via numerical inversion of a reflectance model, in which the above-water reflectance is expressed as a quadratic function of the single backscattering albedo, dependent on the absorption and backscatter coefficients. The absorption coefficient is treated as the sum of component spectra consisting of the cultured species (green algae or cyanobacteria), dissolved organic matter, and water (including the temperature dependence of the water absorption spectrum). The backscatter coefficient is approximatedmore » as the scaled Hilbert transform of the culture absorption spectrum with a wavelength-independent vertical offset. Additional terms in the reflectance model account for the pigment fluorescence features and the water surface reflection of sunlight and skylight. For both the green algae and cyanobacteria, the wavelength-independent vertical offset of the backscatter coefficient is found to scale linearly with daily dry weight measurements, providing the capability for a non-sampling measurement of biomass in outdoor ponds. Other fitting parameters in the reflectance model are compared to auxiliary measurements and physics-based calculations. The magnitudes of the sunlight and skylight water-surface contributions derived from the reflectance model compare favorably with Fresnel reflectance calculations, while the reflectance-derived quantum efficiency of Chl-a fluorescence is found to be in agreement with literature values.

    Price, P.N.; Shehabi, A.; Chan, R.W.; Gadgil, A.J.

    2006-06-01

    We compiled and analyzed available data concerning indoor-outdoor air leakage rates and building leakiness parameters for commercial buildings and apartments. We analyzed the data, and reviewed the related literature, to determine the current state of knowledge of the statistical distribution of air exchange rates and related parameters for California buildings, and to identify significant gaps in the current knowledge and data. Very few data were found from California buildings, so we compiled data from other states and some other countries. Even when data from other developed countries were included, data were sparse and few conclusive statements were possible. Little systematic variation in building leakage with construction type, building activity type, height, size, or location within the u.s. was observed. Commercial buildings and apartments seem to be about twice as leaky as single-family houses, per unit of building envelope area. Although further work collecting and analyzing leakage data might be useful, we suggest that a more important issue may be the transport of pollutants between units in apartments and mixed-use buildings, an under-studied phenomenon that may expose occupants to high levels of pollutants such as tobacco smoke or dry cleaning fumes.

  14. D0 Collision Hall Outdoor Fresh Air Makeup

    Markley, D.; /Fermilab

    1992-03-27

    This note will briefly describe the collision hall ventilation system and how D0 will monitor outside air makeup and what actions occur in the event of system failures. The Dzero collision hall has two different fresh air makeup conditions it must meet. They are: (1) Tunnel Barriers removed-Fresh air makeup = 4500 CFM; and (2) Tunnel Barriers in place-Fresh air makeup = 2800 CFM. This note demonstrates how the fresh air minimums are met and guaranteed. The air flow paths and ducts at D0 for both AHU1 and EF-7 are fixed. The blower throughputs are not variable. The software stops on AHU1's dampers will be set for a minimum of 2800 cfm or 4500 cfm of outdoor air continuously added to the HVAC flow stream depending on the tunnel barrier state. AHU1 and EF-7 both have monitoring that can determine reliably as to whether the respective blower is on or off. Since the outside air makeup is fixed as long as the blowers are running, and the software AHU1 damper limits are set, we can rely on the blower status indicators to determine as to whether the collision hall is receiving the proper amount of outside makeup air.

  18. Safety of Hydrogen Systems Installed in Outdoor Enclosures

    SciTech Connect (OSTI)

    Barilo, Nick F.

    2013-11-06

    The Hydrogen Safety Panel brings a broad cross-section of expertise from the industrial, government, and academic sectors to help advise the U.S. Department of Energys (DOE) Fuel Cell Technologies Office through its work in hydrogen safety, codes, and standards. The Panels initiatives in reviewing safety plans, conducting safety evaluations, identifying safety-related technical data gaps, and supporting safety knowledge tools and databases cover the gamut from research and development to demonstration and deployment. The Panels recent work has focused on the safe deployment of hydrogen and fuel cell systems in support of DOE efforts to accelerate fuel cell commercialization in early market applications: vehicle refueling, material handling equipment, backup power for warehouses and telecommunication sites, and portable power devices. This paper resulted from observations and considerations stemming from the Panels work on early market applications. This paper focuses on hydrogen system components that are installed in outdoor enclosures. These enclosures might alternatively be called cabinets, but for simplicity, they are all referred to as enclosures in this paper. These enclosures can provide a space where a flammable mixture of hydrogen and air might accumulate, creating the potential for a fire or explosion should an ignition occur. If the enclosure is large enough for a person to enter, and ventilation is inadequate, the hydrogen concentration could be high enough to asphyxiate a person who entered the space. Manufacturers, users, and government authorities rely on requirements described in codes to guide safe design and installation of such systems. Except for small enclosures used for hydrogen gas cylinders (gas cabinets), fuel cell power systems, and the enclosures that most people would describe as buildings, there are no hydrogen safety requirements for these enclosures, leaving gaps that must be addressed. This paper proposes that a technical

    1995-08-07

    After months of delays, the sale of Petroleos del Peru SA (Petroperu) was postponed earlier this year until after the elections, which saw Peru`s incumbent President Alberto Fujimori reelected. In June, Fujimori appointed Amado Yataco Minister of Energy and Mines. Yataco, also serving as president of the privatization commission Copri, said a decision on the sale of Petroperu would be made quickly, perhaps by July 28, ahead of this report`s presstime. The uncertain status of Petroperu has not, however, slowed activity in Peru`s petroleum sector. The paper first discusses privatization plans and Petroperu`s budget, then describes exploration and development activities in the supergiant Camisea gas/condensate fields in the central southern jungle. Activities in several smaller fields are briefly described.

    Bajer, E.R.

    1982-08-23

    Mr. Bajer feels that elimination of many federal conservation programs will have no effect on the US goal of reducing oil imports because the private sector can do a better job of providing these efforts. He notes that many government programs were the result of overreaction to the 1973 oil embargo, when Congress misread the public's willingness to respond. The American people have taken the initiative, however, and have reduced their energy consumption and import rates. Mr. Bajer further notes that, according to the DOE Office of Policy, Planning and Analysis, DOE's conservation programs accounted for less than 5% of reduction of energy use per unit of GNP. He thinks that new policies will allow market forces to continue providing conservation incentives and will remove government intervention and competition with the private sector. (DCK)

    1998-10-19

    The U.S. Department of Energy (DOE) launched the Contract Reform Initiative in 1994 in order to improve the effectiveness and effkiency of managing major projects and programs. The intent of this initiative is to help DOE harness both technical and market forces to reduce the overall cost of accomplishing DOE's program goals. The new approach transfers greater risk to private contractors in order to develop incentives that align contractor performance with DOE's objectives. In some cases, this goal can be achieved through public-private partnerships wherein the govermhent and the contractor share risks associated with a project in a way that optimizes its economics. Generally, this requires that project risks are allocated to the party best equipped to manage and/or underwrite them. While the merits of privatization are well documented, the question of how privatized services should be financed is often debated. Given the cost of private sector equity and debt, it is difficult to ignore the lure of the government's "risk free" cost of capital. However, the source of financing for a project is an integral part of its overall risk allocation, and therefore, participation by the government as a financing source could alter the allocation of risks in the project, diminishing the incentive structure. Since the government's participation in the project's financing often can be a requirement for financial feasibility, the dilemma of structuring a role for the government without undermining the success of the project is a common and difficult challenge faced by policymakers around the world. However, before reverting to a traditional procurement approach where the government enters into a cost-plus risk profile, the government should exhaust all options that keep the private entity at risk for important aspects of the project. Government participation in a project can include a broad range of options and can be applied with precision to bridge a gap in the project

    2007-06-25

    A field study was conducted in an unoccupied single story residence in Clovis, California to provide data to address issues important to assess the indoor exposure to particles of outdoor origin. Measurements of black and organic carbonaceous aerosols were performed using a variety of methods, resulting in both near real-time measurements as well as integrated filter based measurements. Comparisons of the different measurement methods show that it is crucial to account for gas phase adsorption artifacts when measuring organic carbon (OC). Measured concentrations affected by the emissions of organic compounds sorbed to indoor surfaces imply a higher degree of infiltration of outdoor organic carbon aerosols into the indoor environment for our unoccupied house. Analysis of the indoor and outdoor data for black carbon (BC) aerosols show that, on average, the indoor concentration of black carbon aerosols behaves in a similar manner to sulfate aerosols. In contrast, organic carbon aerosols are subject to chemical transformations indoors that, for our unoccupied home, resulted in lower indoor OC concentrations than would be expected by physical loss mechanisms alone. These results show that gas to particle partitioning of organic compounds, as well as gas to surface interactions within the residence, are an important process governing the indoor concentration to OC aerosols of outdoor origin.

    1996-09-30

    The U.S. Department of Energy has chosen to accomplish the Tank Waste Remediation System disposal mission via privatization. The disposal mission has been divided into two phases. Phase I, a `proof of concept` phase, will establish and demonstrate the technical, commercial, and procurement capabilities necessary for privatization to proceed. Once established on this relatively small scale, privatization will be expanded, through a second competition, in the form of a second phase (Phase II) to dispose of the remainder of the tank waste. The Phase I privatization site will be located in the former Grout Disposal Site area. To prepare the site for use for the private contractors, utilities must be extended from the 200 East Area infrastructure. This document describes the design requirements for the prime water services; i.e raw, fire suppression and sanitary (potable) to be provided to the private contractors. These requirements will be used in directing the conceptual design of these proposed water services.

    In China`s 9th 5-year plan (1996-2000), the Chinese government has placed high priority on energy conservation. The China Green Lights Program (CGLP) is listed as one of the key projects of energy conservation. The basic strategy of the CGLP is to mobilise all of the potential contributors to participate in the program, and to use market signals and supplementary non-market instruments to facilitate its implementation. Governmental funds and loans will be used as seed money to attract private participation in the program. The program contains the following elements: (1) Information dissemination to educate the public on the economic and other values of the program and to provide CGLP information to increase consumer awareness and, as a result, increase the demand for energy-efficient lighting systems. (2) Development of standards and codes for lighting systems, establishment of product specifications, and enforcement of product standards. (3) Development of quality certification and labelling system to provide assurances to consumers that the products they are purchasing will meet their performance and cost saving expectations. (4) Highlighted support and financing for production technology development and production capacity expansion. (5) Demonstration and pilot projects to boost consumer confidence in green lighting systems and to demonstrate new production technologies and processes. (6) International co-operation to expand the international exchange and absorb advanced technology and experience for implementation of the China Green Lights Program.

    SciTech Connect (OSTI)

    BROWN, N.R.

    2001-02-01

    Privatization acquisition strategies embody substantial contract reform principles-private financing and ownership, competition, fixed prices, and payment only upon delivery of services-which in time became the recipe for privatization of Department of Energy (DOE) Environmental Management (EM) cleanup projects. Privatization changes the federal government's approach from traditional cost-plus contracting, where the federal government pays the contractor as the project progresses, to a strategy where the federal government pays for products or services as they are delivered. To be successful, the privatization requires additional risk taking by the contractor. This paper focuses on why the Tank Waste Remediation System (TWRS) pursued privatization, how the TWRS Privatization Project matured, and why the privatization project moved to an alternate path. The paper is organized as follows: a description of the TWRS-Privatization framework, how the project changed from the original request for proposal through the decision not to proceed to Part B-2, and the lessons learned during evolution of the effort, including what worked as well as what went wrong and how such negative outcomes might be prevented in the future.

    Optical vortices and orbital angular momentum are currently topical subjects in the optics literature. Although seemingly esoteric, they are, in fact, the generic state of light and arise whenever three or more plane waves interfere. To be observed by eye the light must be monochromatic. Laser speckle is one such example, where the optical energy circulates around each black spot, giving a local orbital angular momentum. This talk with report three on-going studies. First, when considering a volume of interfering waves, the laser specs map out threads of complete darkness embedded in the light. Do these threads form loops? Links? Or even knots? Second, when looking through a rapidly spinning window, the image of the world on the other side is rotated: true or false? Finally, the entanglement of orbital angular momentum states means measuring how the angular position of one photons sets the angular momentum of another: is this an angular version of the EPR (Einstein, Podolsky, and Rosen) paradox?

  9. Harnessing the market: The opportunities and challenges of privatization

    SciTech Connect (OSTI)

    1997-01-01

    The decision to privatize comes from a policy determination that the Government no longer needs particular assets or no longer needs to be in control of all the means by which products or services are obtained or delivered. Most broadly defined, privatization substitutes, in whole or in part, private market mechanisms for the traditional Government role as employer, financier, owner, operator, and/or regulator of a product or service. This definition admits a wide variety of actions, from innovative contractual arrangements to outright divestiture of activities or assets. But all of these actions share common objectives: to remove the agency from those activities that are not inherently governmental functions or core business lines; to improve the management of remaining activities; to reduce the costs of doing business; and to shift greater performance and financial risk to the private sector. This report by the Privatization Working Group provides an indepth analysis of the major issues that surround privatization within the Department of Energy (DOE). The report divides privatization initiatives at the DOE into three major types: divestiture of functions, contracting out, and asset transfers. It includes the results of a survey of the entire DOE system that identifies more than 200 potential privatization opportunities. The report also includes 13 case studies that explore actual DOE privatization efforts over the past 2 years. Additionally, it summarizes the key legal authorities that govern each of the three types of privatization opportunities in the DOE. The report makes a series of recommendations and outlines accompanying actions that will help the DOE seize the opportunities presented by privatization and confront its challenges.

    We deployed a 855 cm2 thin-film, single-junction gallium arsenide (GaAs) photovoltaic (PV) module outdoors. Due to its fundamentally different cell technology compared to silicon (Si), the module responds differently to outdoor conditions. On average during the test, the GaAs module produced more power when its temperature was higher. We show that its maximum-power temperature coefficient, while actually negative, is several times smaller in magnitude than that of a Si module used for comparison. The positive correlation of power with temperature in GaAs is due to temperature-correlated changes in the incident spectrum. We show that a simple correction based on precipitable water vapor (PWV) brings the photocurrent temperature coefficient into agreement with that measured by other methods and predicted by theory. The low operating temperature and small temperature coefficient of GaAs give it an energy production advantage in warm weather.

    The process of characterizing human exposure to particulate matter requires information on both particle concentrations in microenvironments and the time-specific activity budgets of individuals among these microenvironments. Because the average amount of time spent indoors by individuals in the US is estimated to be greater than 75%, accurate characterization of particle concentrations indoors is critical to exposure assessments for the US population. In addition, it is estimated that indoor particle concentrations depend strongly on outdoor concentrations. The spatial and temporal variations of indoor particle concentrations as well as the factors that affect these variations are important to health scientists. For them, knowledge of the factors that control the relationship of indoor particle concentrations to outdoor levels is particularly important. In this report, we identify and evaluate sources of data for those factors that affect the transport to and concentration of outdoor particles in the indoor environment. Concentrations of particles indoors depend upon the fraction of outdoor particles that penetrate through the building shell or are transported via the air handling (HVAC) system, the generation of particles by indoor sources, and the loss mechanisms that occur indoors, such as deposition. To address these issues, we (i) identify and assemble relevant information including the behavior of particles during air leakage, HVAC operations, and particle filtration; (ii) review and evaluate the assembled information to distinguish data that are directly relevant to specific estimates of particle transport from those that are only indirectly useful and (iii) provide a synthesis of the currently available information on building air-leakage parameters and their effect on indoor particle matter concentrations.

    Performance data is provided for current Sunpak production collectors. The effects of an improved manifold are seen from the test results. The test results show excellent correlation between the solar simulator derived test results and outdoor test results. Also, because of different incident angle modifiers, the all-day efficiency of this collector with a diffuse reflector is found to be comparable to the performance with the standard shaped specular reflector.

    Thin-film photovoltaic modules are known to exhibit light-induced transient behavior which interferes with accurate and repeatable measurements of power. Typically power measurements are made after a light exposure in order to target a 'light state' of the module that is representative of outdoor performance. Here we show that the concept of a unique light state is poorly defined for both CIGS and CdTe modules. Instead we find that their metastable state after a light exposure can depend on the temperature of the module during the exposure. We observe changes in power as large as 5.8% for a 20 degrees C difference in light exposure temperature. These results lead us to conclude that for applications in which reproducibility and repeatability are critical, module temperature should be tightly controlled during light exposure.

    Reversible performance changes due to light exposure frustrate repeatable performance measurements on CdTe PV modules. It is common to use extended light-exposure to ensure that measurements are representative of outdoor performance. We quantify the extent to which such a light-exposed state depends on module temperature and consider bias in the dark to aid in stabilization. We evaluate the use of dark forward bias to bring about a performance state equivalent to that obtained with light exposure, and to maintain a light-exposed state prior to STC performance measurement. Our results indicate that the most promising method for measuring a light-exposed state is to use light exposure at controlled temperature followed by prompt STC measurement with a repeatable time interval between exposure and the STC measurement.

    1995-08-01

    Two-dimensional laminar forced convection on an outdoor fenestration surface, with the wind perpendicular to the glazing surface, was analyzed using the penalty function approach finite-element method (FEM). The air far from the fenestration surface (free-stream conditions) was assumed to be at ASHRAE standard fenestration conditions of {minus}18 C (0 F) and 6.7 m/s (15 mph). A prototype fenestration configuration of a typical wood casement window, consisting of a double-step frame and an insulating glazing unit (IGU), was used in defining the outdoor fenestration profile. A flat-plate geometry was also considered for purposes of comparison with other available numerical and experimental results and for validation of the results for the actual fenestration profile. The results are reported in the form of velocity vector plots and local convective surface heat transfer coefficients. Recommendations on the local outdoor surface convective heat transfer coefficient for use in two- and three-dimensional heat transfer analyses of fenestration systems are presented.

  18. Calibrating Pyrgeometers Outdoors Independent from the Reference Value of the Atmospheric Longwave Irradiance

    In this article, we describe a method for the calibration of thermopile pyrgeometers in the absence of a reference for measurement of atmospheric longwave irradiance. This is referred to as the incoming longwave irradiance in this article. The method is based on an indoor calibration using a low-temperature blackbody source to obtain the calibration coefficients that determine the pyrgeometer's radiation characteristics. From these coefficients the outgoing irradiance of the pyrgeometer can be calculated. The pyrgeometer is then installed outdoors on an aluminum plate that is connected to a circulating temperature bath. By adjusting the temperature bath to the approximate value of the effective sky temperature, the pyrgeometer's body temperature is lowered changing the pyrgeometer's thermopile output. If the incoming longwave irradiance is stable, the slope of the outgoing irradiance versus the pyrgeometer's thermopile output is the outdoor net irradiance responsivity (RSnet), independent of the absolute value of the atmospheric longwave irradiance. The indoor calibration coefficients and the outdoor RSnet are then used in the pyrgeometer equation to calculate the incoming longwave irradiance. To evaluate this method, the calculated irradiance using the derived coefficients was compared to the irradiance measured using a pyrgeometer with direct traceability to the World Infrared Standard Group (WISG). This is maintained at the Physikalisch-Meteorologisches Observatorium Davos, World Radiation Center, Switzerland. Based on results from four pyrgeometers calibrations, this method suggests measurement agreement with the WISG to within +/- 3 W/m2 for all sky conditions.

    Unlike the oil industry, Russian gas is dominated by an officially sanctioned monopoly--Joint Stock Society (RAO) Gazprom. The company produces, transports, and exports most of the gas in Russia, the world leader in gas reserves. Two major challenges confront Gazprom as it adapts to existence as a private concern. One is financing of a major pipeline to Europe for export of gas produced in fields under development in the Yamal Peninsula. The other is collection of debts owed it by customers, both in and outside of Russia, for past gas deliveries. While it grapples with those challenges and the strains of operating a huge gas production and transportation system, Gazprom also must deal with questions about whether it should continue as a monopoly--questions not likely to be answered until Russia`s political situation is more certain than it is now. This paper reviews Gazprom`s production, processing, gas transportation, and marketing businesses. It describes its financing strategies for construction of new pipelines.

    2015-09-15

    The transport of particles via intermittent filamentary structures in the private flux region (PFR) of plasmas in the MAST tokamak has been investigated using a fast framing camera recording visible light emission from the volume of the lower divertor, as well as Langmuir probes and IR thermography monitoring particle and power fluxes to plasma-facing surfaces in the divertor. The visible camera data suggest that, in the divertor volume, fluctuations in light emission above the X-point are strongest in the scrape-off layer (SOL). Conversely, in the region below the X-point, it is found that these fluctuations are strongest in the PFR of the inner divertor leg. Detailed analysis of the appearance of these filaments in the camera data suggests that they are approximately circular, around 1–2 cm in diameter, but appear more elongated near the divertor target. The most probable toroidal quasi-mode number is between 2 and 3. These filaments eject plasma deeper into the private flux region, sometimes by the production of secondary filaments, moving at a speed of 0.5–1.0 km/s. Probe measurements at the inner divertor target suggest that the fluctuations in the particle flux to the inner target are strongest in the private flux region, and that the amplitude and distribution of these fluctuations are insensitive to the electron density of the core plasma, auxiliary heating and whether the plasma is single-null or double-null. It is found that the e-folding width of the time-average particle flux in the PFR decreases with increasing plasma current, but the fluctuations appear to be unaffected. At the outer divertor target, the fluctuations in particle and power fluxes are strongest in the SOL.

    This report provides background data upon which residential lighting fixture energy conservation programs can be built. The current stock of residential lighting is described by usage level, lamp wattage, fixture type, and location within the house. Data are discussed that indicate that 25% of residential fixtures are responsible for 80% of residential lighting energy use, and that justify targeting these fixtures as candidates for retrofit with energy-efficient fixtures. Fixtures determined to have the highest energy use are hardwired ceiling fixtures in kitchens, living/family rooms, dining rooms, and outdoors. An assessment of the market for residential fixtures shows that nearly half of new residential fixtures are imported, 61% of new fixtures sold are hardwired, and about half of all new fixtures sold are for ceiling installation.

    Portugal`s recently privatized state oil company Petrogal is about to embark on a major expansion worldwide. That comes against the backdrop of major change in Portugal`s energy sector and the rocky road to Petrogal`s partial privatization. Despite the controversy, there remain opportunities for foreign companies investing in Portugal`s energy sector. The most attractive opportunities are in Portugal`s downstream petroleum sector and in the country`s continuing campaign to develop its natural gas industry. Typical of the latter is Portugal`s participation in the Trans-Maghreb gas pipeline megaproject. The paper discusses the background to privatization, its current status, Petrogal strategy, modernization of refineries, a joint partnership with Venezuela, constraints, energy policy program, gas pipeline privatization, and concerns of the gas industry.

    The Yuma Sector Border Patrol Area is a high flux lighting application in a high temperature environment, presenting a formidable challenge for light-emitting diodes (LEDs). This retrofit is an Energy Savings Performance Contract ENABLE project under the U.S. Department of Energy (DOE) Federal Energy Management Program. If high flux LED technology performs well in a region with high ambient temperature and solar radiation, it can perform well in most outdoor environments. The design process for the Yuma retrofit has already provided valuable knowledge to CBP and DOE. The LED lighting system selected for the retrofit is expected to reduce energy consumption 69% compared to the incumbent quartz metal halide (QMH) lighting system. If the LED lighting system is installed, GATEWAY will continue to document and disseminate information regarding the installation and long-term performance so that others may also gain valuable knowledge from the Yuma Sector Border Patrol Area lighting retrofit.

    1997-06-01

    {open_quotes}Privatization{close_quotes} has become the buzzword of the 1990s not only here in the United States but throughout the world. Privatization has been traditionally defined as the sale/transfer of state-owned (i.e. federal, state, county, city or public) assets to the private sector. Although there are numerous reasons for the privatization of state-owned assets, the primary reasons include the generation of a significant amount of cash to the state (Great Britain`s sale of electric power industry); capitalization of the formerly state-owned utility (sale of the utilities within many countries of the former Soviet Union); and state policy goals of eliminating monopolies, encouraging competition, and restructuring (Chile). Several year ago, the Department of Defense (DoD) and specifically the Department of Army (DoA) initiated its own `Privatization Process`. Coupled with shrinking budgets, workforce and funding resources from the Government, the Army was faced with antiquated utility infrastructure in need of significant upgrades and in some cases total replacements. Recognizing that the provision of utility services was not a core mission of the Army, DoA has encouraged its Installations throughout the country to consider the privatization of the Government-owned utility systems. In compliance with DoA policy, Forces Command (FORSCOM) has been at the forefront of the privatization process. To date, FORSCOM has initiated the process of analyzing the potential privatization of over 30 utility systems at 12 FORSCOM Installations located throughout the country. The FORSCOM Installations include Fort Irwin, CA; Fort Campbell, KY; Fort Bragg, NC; Fort McPherson, GA; Fort Hood, TX; Fort Polk, LA; Fort Lewis, WA; Fort Riley, KS; Fort Stewart, GA; Hunter Army Airfield, GA; Fort Carson, CO; Fort Devens, MA; Fort Dix, NJ; and Fort Gillem, GA.

    Highlights: • We compared efficiency and effectiveness of waste collection by the public and private sector. • Public sector performs better than private sector in some areas and vice versa. • Outsourcing waste collection in developing countries is hindered by limited capacity on contractual issues. • Outsourcing collection in developing countries is hampered by inadequate waste information. • There is need to build capacity in the public sector of developing countries to support outsourcing. - Abstract: Formal privatization of solid waste collection activities has often been flagged as a suitable intervention for some of the challenges of solid waste management experienced by developing countries. Proponents of outsourcing collection to the private sector argue that in contrast to the public sector, it is more effective and efficient in delivering services. This essay is a comparative case study of efficiency and effectiveness attributes between the public and the formal private sector, in relation to the collection of commercial waste in Gaborone. The paper is based on analysis of secondary data and key informant interviews. It was found that while, the private sector performed comparatively well in most of the chosen indicators of efficiency and effectiveness, the public sector also had areas where it had a competitive advantage. For instance, the private sector used the collection crew more efficiently, while the public sector was found to have a more reliable workforce. The study recommends that, while formal private sector participation in waste collection has some positive effects in terms of quality of service rendered, in most developing countries, it has to be enhanced by building sufficient capacity within the public sector on information about services contracted out and evaluation of performance criteria within the contracting process.

    Background: Predicted rise in global mean temperature and intensification of heat waves associated with climate change present an increasing challenge for occupational health and safety. Although important scientific knowledge has been gathered on the health effects of heat, very few studies have focused on quantifying the association between outdoor heat and mortality or morbidity among workers. Objective: To quantify the association between occupational heat-related illnesses and exposure to summer outdoor temperatures. Methods: We modeled 259 heat-related illnesses compensated by the Workers' Compensation Board of Quebec between May and September, from 1998 to 2010, with maximum daily summer outdoor temperatures in 16 health regions of Quebec (Canada) using generalized linear models with negative binomial distributions, and estimated the pooled effect sizes for all regions combined, by sex and age groups, and for different time lags with random-effect models for meta-analyses. Results: The mean daily compensation count was 0.13 for all regions of Quebec combined. The relationship between daily counts of compensations and maximum daily temperatures was log-linear; the pooled incidence rate ratio (IRR) of daily heat-related compensations per 1 °C increase in daily maximum temperatures was 1.419 (95% CI 1.326 to 1.520). Associations were similar for men and women and by age groups. Increases in daily maximum temperatures at lags 1 and 2 and for two and three-day lag averages were also associated with increases in daily counts of compensations (IRRs of 1.206 to 1.471 for every 1 °C increase in temperature). Conclusion: This study is the first to quantify the association between occupational heat-related illnesses and exposure to summer temperatures in Canada. The model (risk function) developed in this study could be useful to improve the assessment of future impacts of predicted summer outdoor temperatures on workers and vulnerable groups, particularly in colder

    We present the application of a phenomenological four parameter equation to fit and analyze regularly measured current density-voltage JV curves of a CdTe module during 2.5 years of outdoor operation. The parameters are physically meaningful, i.e. the short circuit current density Jsc, open circuit voltage Voc and differential resistances Rsc, and Roc. For the chosen module, the fill factor FF degradation overweighs the degradation of Jsc and Voc. Interestingly, with outdoor exposure, not only the conductance at short circuit, Gsc, increases but also the Gsc(Jsc)-dependence. This is well explained with an increase in voltage dependent charge carrier collection in CdTe.

    One of the issues that came out of the Tank Waste Remediation System (TWRS) Privatization Interface Control Document (ICD) effort was the need to identify below grade obstructions that exist where the TWRS Privatization Phase 1 transfer/feed corridors pass through the former Grout complex (ICD Issue 9C). Due to the numerous phases of construction at the complex, and the lack of consolidated facility configuration drawings, as-built (or as-recorded) information on the area is difficult to find, let alone decipher. To resolve the issue, this study was commissioned to identify and consolidate the as-recorded information available (drawings and Engineering Change Notices, ECNS).

    As privatization and liberalization proceed in India--the world`s second largest growth market for electricity--sensible experimentation by the states on the rules of the game is vital. A new joint venture approach in Rajasthan may be a helpful model. This article provides an overview of the principal challenges confronting US utilities interested in investing in distribution in India as well as a summary of two mechanisms developed to facilitate private investment. These challenges also should be considered in view of the changing political conditions in India owing to the recent election of the coalition government led by the Bharatiya Janata Party.

  2. Measuring the Optical Performance of Evacuated Receivers via an Outdoor Thermal Transient Test: Preprint

    Modern parabolic trough solar collectors operated at high temperatures to provide the heat input to Rankine steam power cycles employ evacuated receiver tubes along the collector focal line. High performance is achieved via the use of a selective surface with a high absorptance for incoming short-wave solar radiation and a low emittance for outgoing long-wave infrared radiation, as well as the use of a hard vacuum to essentially eliminate convective and conductive heat losses. This paper describes a new method that determines receiver overall optical efficiency by exposing a fluid-filled, pre-cooled receiver to one sun outdoors and measuring the slope of the temperature curve at the point where the receiver temperature passes the glass envelope temperature (that is, the point at which there is no heat gain or loss from the absorber). This transient test method offers the potential advantages of simplicity, high accuracy, and the use of the actual solar spectrum.

  4. Secure quantum private information retrieval using phase-encoded queries

    We propose a quantum solution to the classical private information retrieval (PIR) problem, which allows one to query a database in a private manner. The protocol offers privacy thresholds and allows the user to obtain information from a database in a way that offers the potential adversary, in this model the database owner, no possibility of deterministically establishing the query contents. This protocol may also be viewed as a solution to the symmetrically private information retrieval problem in that it can offer database security (inability for a querying user to steal its contents). Compared to classical solutions, the protocol offers substantial improvement in terms of communication complexity. In comparison with the recent quantum private queries [Phys. Rev. Lett. 100, 230502 (2008)] protocol, it is more efficient in terms of communication complexity and the number of rounds, while offering a clear privacy parameter. We discuss the security of the protocol and analyze its strengths and conclude that using this technique makes it challenging to obtain the unconditional (in the information-theoretic sense) privacy degree; nevertheless, in addition to being simple, the protocol still offers a privacy level. The oracle used in the protocol is inspired both by the classical computational PIR solutions as well as the Deutsch-Jozsa oracle.

    Algal biofuels and valuable co-products are being produced in both open and closed cultivation systems. Growing algae in open pond systems may be a more economical alternative, but this approach allows environmental microorganisms to colonize the pond and potentially infect or outcompete the algal “crop.” In this study, we monitored the microbial community of an outdoor, open raceway pond inoculated with a high lipid-producing alkaliphilic alga, Chlorella vulgaris BA050. The strain C. vulgaris BA050 was previously isolated from Soap Lake, Washington, a system characterized by a high pH (~9.8). An outdoor raceway pond (200 L) was inoculated with C. vulgarismore » and monitored for 10 days and then the culture was transferred to a 2,000 L raceway pond and cultivated for an additional 6 days. Community DNA samples were collected over the 16-day period in conjunction with water chemistry analyses and cell counts. Universal primers for the SSU rRNA gene sequences for Eukarya, Bacteria, and Archaea were used for barcoded pyrosequence determination. The environmental parameters that most closely correlated with C. vulgaris abundance were pH and phosphate. Community analyses indicated that the pond system remained dominated by the Chlorella population (93% of eukaryotic sequences), but was also colonized by other microorganisms. Bacterial sequence diversity increased over time while archaeal sequence diversity declined over the same time period. Using SparCC co-occurrence network analysis, a positive correlation was observed between C. vulgaris and Pseudomonas sp. throughout the experiment, which may suggest a symbiotic relationship between the two organisms. The putative relationship coupled with high pH may have contributed to the success of C. vulgaris. As a result, the characterization of the microbial community dynamics of an alkaliphilic open pond system provides significant insight into open pond systems that could be used to control photoautotrophic biomass

    The widespread absence of systems for real-time measurement and feedback control, of minimum outdoor air intake rates in HVAC systems contributes to the poor control of ventilation rates in commercial buildings. Ventilation rates affect building energy consumption and influence occupant health. The project designed fabricated and tested four prototypes of systems for measuring rates of outdoor air intake into roof top air handlers. All prototypes met the ±20% accuracy target at low wind speeds, with all prototypes accurate within approximately ±10% after application of calibration equations. One prototype met the accuracy target without a calibration. With two of four prototype measurement systems, there was no evidence that wind speed or direction affected accuracy; however, winds speeds were generally below usually 3.5 m s-1 (12.6 km h-1) and further testing is desirable. The airflow resistance of the prototypes was generally less than 35 Pa at maximum RTU air flow rates. A pressure drop of this magnitude will increase fan energy consumption by approximately 4%. The project did not have resources necessary to estimate costs of mass produced systems. The retail cost of components and materials used to construct prototypes ranged from approximately $1,200 to $1,700. The test data indicate that the basic designs developed in this project, particularly the designs of two of the prototypes, have considerable merit. Further design refinement, testing, and cost analysis would be necessary to fully assess commercial potential. The designs and test results will be communicated to the HVAC manufacturing community.

    The present study examines how climatic conditions and pond design affect the growth performance of microalgae. From January to April of 2011, outdoor batch cultures of Nannochloropsis salina were grown in three replicate 780 L conventional raceways, as well as in an experimental 7500 L ARID (Algae Raceway Integrated Design) pond. The ARID culture system utilizes a series of 8 to 20 cm deep basins and a 1.5 m deep canal to enhance light exposure and mitigate temperature variations and extremes. The ARID culture reached the stationary phase 27 days earlier than the conventional raceways, which can be attributed to its superior temperature management and shallower basins. On a night when the air temperature dropped to -9 C, the water temperature was 18 C higher in the ARID pond than in the conventional raceways. Lipid and fatty acid content ranged from 16 - 25 % and 5 - 15 %, respectively, as a percentage of AFDW. Palmitic, palmitoleic, and eicosapentaenoic acid comprised the majority of fatty acids. While the ARID culture system achieved nearly double the volumetric productivity relative to the conventional raceways (0.023 vs 0.013 g L-1day-1), areal biomass productivities were of similar magnitude in both pond systems (3.34 vs. 3.47 g m-2day-1), suggesting that the ARID pond design has to be further optimized, most likely by increasing the culture depth or operating at higher cell densities while maintaining adequate mixing.

    Solid-state lighting using light-emitting diodes (LEDs) has the potential to reduce energy consumption for lighting by 50% while revolutionizing the way we illuminate our homes, work places, and public spaces. Nevertheless, substantial technical challenges remain in order for solid-state lighting to significantly displace the well-developed conventional lighting technologies. We review the potential of LED solid-state lighting to meet the long-term cost goals.
