VALHALLA, N.Y.--(BUSINESS WIRE)--The Ross Solar Group, a Con Edison Solutions company, has begun preparations to install a third record-setting solar project for Gengras Motor Cars at the dealership group’s Chrysler / Dodge / Jeep / Ram facility on Connecticut Blvd., in East Hartford, Conn. The SunPower® Helix™ Roof Solution, a fully integrated commercial solar power platform, will feature 954 high efficiency SunPower E-Series solar panels. Upon completion, the installation will be the largest single SunPower rooftop solar installation to date in East Hartford, Conn. In 2015, Ross Solar installed two separate SunPower solar power systems for Gengras Motor Cars at their Volvo and Chevrolet facilities on Connecticut Blvd., totaling 418 kilowatts in size, which at the time were the two largest single SunPower rooftop solar installations in East Hartford. According to estimates provided by the U.S. Environmental Protection Agency, the forthcoming installation will offset 266 metric tons of greenhouse gas emissions annually, representing a reduction in Co2 emissions equivalent to not burning 283,559 pounds of coal each year, and equal to the carbon sequestered by 6,887 tree seedlings grown for ten years. East Hartford-based Gengras Motor Cars has been a leading member of the Connecticut business community since 1937, with Volvo, Chevrolet, Dodge / Chrysler / Jeep / Ram, and Harley Davidson showrooms and service facilities on Connecticut Blvd., as well as a Volvo dealership in North Haven, Conn., a BMW dealership in Springfield, Mass., and a Honda dealership in Lebanon, NH. “ Solar is an important component of our long-term strategy, helping us to reduce operational expenses and remain competitive, while underscoring our commitment as a responsible corporate partner to grow renewable energy in East Hartford, ” said third-generation Gengras Motor Cars Co-Owner Jonathan Gengras. “ Ross Solar’s commitment to quality, customer service, and full transparency, echoes our pledge to our own customers, and once again makes them the clear choice as the right partner for us.” The project was made possible through awards that Ross Solar secured on Gengras Motor Cars’ behalf through the Connecticut ZREC program. “ We are proud to partner with Gengras Motor Cars again on this high-profile renewable energy project, and we appreciate the confidence and the level of trust that the Gengras Family continues to place in us,” said Robert Kline, PV Solar Consultant at Ross Solar.

The major challenge of photocatalytic water splitting, the prototypical reaction for the direct production of hydrogen by using solar energy, is to develop low-cost yet highly efficient and stable semiconductor photocatalysts. Herein, an effective strategy for synthesizing extremely active graphitic carbon nitride (g-C3N4) from a low-cost precursor, urea, is reported. The g-C3N4 exhibits an extraordinary hydrogen-evolution rate (ca. 20 000μmol h-1 g-1 under full arc), which leads to a high turnover number (TON) of over 641 after 6h. The reaction proceeds for more than 30h without activity loss and results in an internal quantum yield of 26.5 under visible light, which is nearly an order of magnitude higher than that observed for any other existing g-C3N 4 photocatalysts. Furthermore, it was found by experimental analysis and DFT calculations that as the degree of polymerization increases and the proton concentration decreases, the hydrogen-evolution rate is significantly enhanced. A recipe for success: Graphitic carbon nitride exhibited an internal quantum yield of 26.5 at 400nm when prepared by a specific tailored recipe. The activity was shown to be inversely proportional to the protonation status at specific nitrogen sites in heptazine units (see picture; N blue, C gray, H white). Theoretical results indicated that protonation significantly influences reductive power and charge migration to active sites. © 2014 The Authors. Published by Wiley-VCH Verlag GmbH & Co. KGaA.

While the chemical energy in fossil fuels has enabled the rapid rise of modern civilization, their utilization and accompanying anthropogenic CO2 emissions is occurring at a rate that is outpacing nature's carbon cycle. Its effect is now considered to be irreversible and this could lead to the demise of human society. This is a complex issue without a single solution, yet from the burgeoning global research activity and development in the field of CO2 capture and utilization, there is light at the end of the tunnel. In this article a couple of recent advances are illuminated. Attention is focused on the discovery of gas-phase, light-assisted heterogeneous catalytic materials and processes for CO2 photoreduction that operate at sufficiently high rates and conversion efficiencies, and under mild conditions, to open a new pathway for an energy transition from today's "fossil fuel economy" to a new and sustainable "CO2 economy". Whichever of the competing CO2 capture and utilization approaches proves to be the best way forward for the development of a future CO2-based solar fuels economy, hopefully this can occur in a period short enough to circumvent the predicted adverse consequences of greenhouse gas climate change. The future is bright for the transformation of sunlight into renewable solar fuels that can sustain civilization. Recent advances that focus on the discovery of gas-phase, light-assisted, heterogeneous catalytic materials and processes for CO2 photo-reduction that operate at sufficiently high rates and conversion efficiencies to facilitate an energy transition from today's unsustainable "fossil fuel economy" to a new and sustainable "CO2 economy" are highlighted. © 2015 WILEY-VCH Verlag GmbH & Co.

Monthly median values of hourly total electron content (TEC) is obtained with GPS at a station near northern anomaly crest, Rajkot (geog. 22.29°N, 70.74°E; geomag. 14.21°N, 144.9°E) to study the variability of low latitude ionospheric behavior during low solar activity period (April 2005 to March 2006). The TEC exhibit characteristic features like day-to-day variability, semiannual anomaly and noon bite out. The observed TEC is compared with latest International Reference Ionosphere (IRI) - 2007 model using options of topside electron density, NeQuick, IRI01-corr and IRI-2001 by using both URSI and CCIR coefficients. A good agreement of observed and predicted TEC is found during the daytime with underestimation at other times. The predicted TEC by NeQuick and IRI01-corr is closer to the observed TEC during the daytime whereas during nighttime and morning hours, IRI-2001 shows lesser discrepancy in all seasons by both URSI and CCIR coefficients. © 2011 COSPAR.

The present invention overcomes the limitations of Siemens reactors by providing for the deposition reaction to occur inside of a sealed crucible rather than inside of the overall cavity of a water-cooled reactor. The crucible itself is positioned inside of a cartridge reactor, which can have heat shields between crucible and the reactor walls to significantly reduce radiant energy losses. Additionally, the ratio of deposition surface area to cavity volume in the crucible is much higher than that in the ratio of rod deposition surface area to overall cavity volume in Siemens reactors, which results in a much higher contact percentage of gas molecules with the deposition surfaces. This in turn results in a much higher actual conversion ratio of material in the gas to material on the deposition surfaces.
